Lunar/Planetary Events The Japanese Advanced Earth Observing Satellite (ADEOS) Midori was developed to establish platform technology for Earth Advanced Earth Observing System (EOS) spacecraft and inter-orbit Observing Satellite communication technology for the transmission of Earth observation data. In addition, ADEOS contributed global 24277 observation of environmental change to the international community during the pre-EOS era. NASA's Mission to Planet Facts in Brief Earth (MTPE) program contributed two instruments for the ADEOS mission. Launch Date: 1996-08- 16 ADEOS was a sun-synchronous, morning equator-crossing (in : H-2 descending node at about 10:30 a.m.), polar orbiting Launch spacecraft. It had a modular type shape with a deployable one Site: Tanegashima, Japan wing solar paddle. The body measured 4 x 4 x 5 m and the Mass: 3500.0 kg solar paddle was 3 x 13 m in size. Nominal Power: 5000.0 W ADEOS was three-axis stabilized by a zero momentum strap- down attitude-control system. Attitude was maintained by four reaction wheels, two magnetometers, an inertial reference unit, Funding Agency and two hydrazine thrusters. Power was provided by a single National Space gallium arsenide flexible solar paddle and five 35 A-hr NiCd Development Agency batteries. Data was transmitted via direct transmission and (NASDA) (Japan) inter-orbit communication through ETS-6. A Mission Data Recorder system on-board ADEOS stored high data rate and low data rate data on separate tape recorders. Discipline

Eight experiments on ADEOS included: (1) Ocean Color and Earth Science Temperature Scanner (OCTS), a NASDA core instrument; (2) Advanced Visible and Near-Infrared Radiometer (AVNIR), a Additional NASDA core instrument; (3) NASA Scatterometer (NSCAT), a Information NASA/MTPE-provided instrument; (4) Total Ozone Mapping Spectrometer (TOMS), a NASA/MTPE provided instrument; (5) Launch/Orbital Polarization and Directionality of the Earth's Reflectances information for ADEOS (POLDER), provided by CNES of ; (6) Interferometric PDMP information for Monitor for Greenhouse Gases (IMG), provided by MITI of ADEOS Japan; (7) Improved Limb Atmospheric Spectrometer (ILAS), provided by Environmental Agency of Japan; and, (8) Telecommunications Retroreflector in Space (RIS), provided by the Environmental information for ADEOS Agency of Japan. Experiments on ADEOS The design lifetime for this mission was three years, but the spacecraft ceased operating on 30 June 1997 for as yet Data collections from unknown reasons. Subsequent flights of ADEOS are planned ADEOS during the EOS era.

Lunar/Planetary Events The Fast Auroral SnapshoT Explorer (FAST) was successfully Small Explorer/FAST launched on 1996-08-21 into its intended orbit. FAST Explorer 70 investigates the plasma physics of auroral phenomena at extremely high time and spatial resolution using the full SMEX/FAST complement of particle and fields instruments. FAST is the Fast Auroral SnapshoT second spacecraft (SAMPEX was first) in the Small Explorer Explorer (SMEX) program at NASA-GSFC. SMEX was established to 24285 provide rapid (3 year development) low cost ($35M development) mission opportunities (1 per year) to the space science community using a single designated Principal Facts in Brief Investigator (PI). Launch Date: 1996-08- In order to capture the auroral phenomena over small time 21 (microseconds) and spatial scales, FAST utilizes high speed Launch data sampling, a large, fast-loading ("burst") memory, and a Vehicle: Pegasus XL smart, on-board software to trigger on the appearance of Launch various key phenomena. Using a 1 Gb solid-state memory and Site: Vandenberg AFB, a data acquisition rate of 8 Mbs (almost two orders of United States magnitude faster than previous satellites), FAST produces Mass: 187.0 kg high-resolution "snapshots" of auroral arcs and other Nominal Power: 60.0 W interesting auroral events. FAST flies in a highly eccentric, near-polar orbit precessing nominally one degree per day. Funding Agency Scientific investigations are operate in a campaign mode (about 60 days long) as apogee transitions through the NASA-Office of Space northern auroral zone and in less intense survey mode during Science Applications the rest of the orbit. (United States)

The FAST mission uses a unique (not a SAMPEX derivative), lightweight, orbit-normal spinner spacecraft developed by the Discipline SMEX project. The spacecraft has body-mounted solar arrays, Space Physics and is spin-stabilized, rotating at 12 rpm with the spin axis normal to the orbit plane ("cartwheel"). The four FAST experiments are: (1) the Electrostatic Analyzers (ESA) for Additional measuring the electron and ion distribution function, (2) the Information Time-of-flight Energy Angle Mass Spectrograph (TEAMS) for measuring the full 3-dimensional distribution function of the Launch/Orbital major ion species, (3) the Tri-Axial Fluxgate and Search-coil information for FAST Magnetometers for measuring magnetic field data, and (4) the PDMP information for Electric Field/Langmuir Probe Instrument for obtaining electric FAST field data and plasma density and temperature. The FAST Telecommunications electric field instrument stopped providing meaningful data information for FAST around 2002, all other instruments and systems continue to function nominally.

Mission Profile After launch on a Delta 7925 (a Delta II Lite launch vehicle with nine strap-on solid-rocket boosters and a Star 48 (PAM-D) third stage) and a 10 month cruise phase, the Mars Global Surveyor was inserted into an elliptical capture orbit at 01:17 UT 12 September 1997. Over the next four months, it was intended that aerobraking maneuvers and thrusters would be used to lower the orbit to the final circular mapping orbit. However, one of the solar panels failed to latch properly when it was deployed and subsequently showed unexpected motion and moved past its fully deployed position when aerobraking began (thought to be due to the fracture of a damper arm and subsequent structural damage). A new aerobraking schedule was employed, which involved slower aerobraking putting less pressure on the solar panels through April 1998, at which time an 11.6 hour science phasing orbit with a 171 km periapsis was achieved and aerobraking was halted. After a 5 month hiatus, aerobraking was resumed on 23 September 1998. Science observations were made periodically during these maneuvers.

After aerobraking ended in February 1999, MGS was in a 118 minute circular polar science mapping orbit with an index altitude of 378 km. The orbit is sun-synchronous (2 a.m./2 p.m.) and maps over the 2 p.m. crossing from south to north (instead of north to south as originally planned). The orbit has a 7 day near-repeat cycle so Mars will be mapped in 26 day cycles. Science mapping began in mid-March 1999, which was summer in the northern hemisphere on Mars. The primary mission lasted one martian year (687 Earth days) through January, 2001. An extended mission took place until April 2002, further extensions were added until contact with the spacecraft was lost on 2 November 2006.

The Mars Global Surveyor mission cost about $154 million to develop and build and $65 million to launch. Mission operations and data analysis cost approximately $20 million/year.

Lunar/Planetary Events The Mars Pathfinder was the second of NASA's low-cost MESUR Pathfinder planetary Discovery missions to be launched. The mission Carl Sagan Memorial consists of a stationary lander and a surface rover. The Station mission had the primary objective of demonstrating the feasibility of low-cost landings on and exploration of the Pathfinder Martian surface. This objective was met by tests of 24667 communications between the rover and lander, and the lander Mars Pathfinder and Earth, tests of the imaging devices and sensors, and tests of the maneuverability and systems of the rover on the Facts in Brief surface. The scientific objectives include atmospheric entry Launch Date: 1996-12- science, long-range and close-up surface imaging, rock and 04 soil composition and material properties experiments, and Launch Vehicle: Delta meteorology, with the general objective being to characterize II 7925 the Martian environment for further exploration. (Mars Launch Site: Cape Pathfinder was formerly known as the Mars Environmental Canaveral, United States Survey (MESUR) Pathfinder.) Mass: 463.0 kg Nominal Power: 35.0 W Mars Pathfinder was launched on a Delta 7925 (a Delta II Lite launch vehicle with nine strap-on solid-rocket boosters and a Star 48 (PAM-D) third stage) at 6:58:00 UT (1:58 a.m. EST) on Funding Agency 4 December 1996. The spacecraft entered the Martian atmosphere on 4 July 1997 directly from its approach NASA-Office of Space hyperbola at about 7300 m/s without going into orbit around Science (United States) the planet. The cruise stage was jettisoned 30 minutes before atmospheric entry. The lander took atmospheric Discipline measurements as it descended. The entry vehicle's heat shield slowed the craft to 400 m/s in about 160 seconds. A 12.5 Planetary Science meter parachute was deployed at this time, slowing the craft to about 70 m/s. The heat shield was released 20 seconds after parachute deployment, and the bridle, a 20 meter long braided Additional Kevlar tether, deployed below the spacecraft. The lander Information separated from the backshell and slid down to the bottom of Launch/Orbital the bridle over about 25 seconds. At an altitude of about 1.6 information for Mars km, the radar altimeter acquired the ground, and about 10 Pathfinder seconds before landing four air bags inflated in about 0.3 seconds forming a 5.2 meter diameter protective 'ball' around PDMP information for the lander. Four seconds later at an altitude of 98 m the three Mars Pathfinder solid rockets, mounted in the backshell, fired to slow the Telecommunications descent, and about 2 seconds later the bridle was cut 21.5 m information for Mars above the ground, releasing the airbag-encased lander. The Pathfinder lander dropped to the ground in 3.8 seconds and impacted at 16:56:55 UT (12:56:55 p.m. EDT) on 4 July 1997 at a velocity Experiments on Mars of 18 m/s - approximately 14 m/s vertical and 12 m/s horizontal Pathfinder - and bounced about 12 meters (40 feet) into the air, bouncing at least another 15 times and rolling before coming to rest Data collections from Mars approximately 2.5 minutes after impact and about 1 km from Pathfinder the initial impact site.

After landing, the airbags deflated and were retracted. http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1996-068A[08/06/2011 23:08:27] NASA - NSSDC - Spacecraft - Details

Pathfinder opened its three metallic triangular solar panels Questions or comments (petals) 87 minutes after landing. The lander first transmitted about this spacecraft can the engineering and atmospheric science data collected during be directed to: Dr. David R. entry and landing, the first signal being received at Earth at Williams. 18:34 UT (2:34 p.m. EDT). The imaging system obtained views of the rover and immediate surroundings and a panoramic view of the landing area and transmitted it to Earth at 23:30 UT. After some maneuvers to clear an airbag out of the way, ramps were deployed and the rover, stowed against one of the petals, rolled onto the surface on 6 July at about 05:40 UT (1:40 a.m. EDT).

The bulk of the lander's task was to support the rover by imaging rover operations and relaying data from the rover to Earth. The lander was also equipped with a meteorology station. Over 2.5 meters of solar cells on the lander petals, in combination with rechargeable batteries, powered the lander. The lander on-board computer is based on 32-bit architecture with 4 million bytes of static random access memory and 64 million bytes of mass memory for storing images. The main lander components are held in a tetrahedral shaped unit in the center of the three petals, with three low-gain antennas extending from three corners of the box and a camera extending up from the center on a 0.8 meter high pop-up mast. Images were taken and experiments performed by the lander and rover until 27 September 1997 when communications were lost for unknown reasons.

The landing site in the Ares Vallis region of Mars is at 19.33 N, 33.55 W. The lander has been named the Sagan Memorial Station. The Ares Vallis region of Mars is a large outwash plain near Chryse Planitia. This region is one of the largest outflow channels on Mars, the result of a huge flood (possibly an amount of water equivalent to the volume of all five Great Lakes) over a short period of time flowing into the martian northern lowlands.

The Mars Pathfinder mission cost approximately $265 million including launch and operations. Development and construction of the lander cost $150 million and the rover about $25 million.

La sonda Mars Pathfinder fue la segunda misión del programa Discovery de la NASA, una iniciativa para la exploración del Sistema Solar con desarrollos cortos del proyectos y bajo coste. Esta misión fue dirigida por el JPL de la NASA y su objetivo principal era la realización de una demostración de tecnologías y conceptos clave que serían usados en futuras misiones a Marte empleando aterrizadores.

INTRODUCCIÓN Además la misión llevaba instrumentos científicos hasta la superficie del planeta rojo para investigar la estructura de la atmósfera marciana, la meteorología, la geología y la composición elemental de las rocas y el suelo. Por último un rover llamado sería desplegado para realizar experimentos tecnológicos y para estudiar las rocas del entorno, convirtiéndose en el primer rover marciano de la historia.

Lanzamiento de la misión Pathfinder LANZAMIENTO Y VIAJE La nave de crucero fue lanzada en un cohete Delta II - 7925 que llevaba acoplado una etapa superior PAM-D (Payload Assist Module), desde Cabo Cañaveral (Torre 17B) en una ventana de lanzamiento de 29 días que comenzaba el 2 de diciembre de 1.996. La nave salió disparada al espacio el 4 de diciembre de 1.996 a las 06:58 GMT. Tras el lanzamiento la nave requiere unos 7 meses de viaje de crucero para llegar a Marte. En esta fase se programaron 4 maniobras de corrección de trayectoria (TCM) para ajustar el recorrido de la etapa de crucero de la sonda los días 10 de enero, 3 de febrero, 6 de mayo y 25 de junio. El seguimiento, la telemetría y los comandos son enviados usando las antenas de la Deep Space Network de la NASA.

Etapa de crucero con el aterrizador en su interior El objetivo para la nave era entrar en la atmósfera marciana, desplegar un paracaidas de frenado que la llevara hasta cerca de la superficie de Marte. Allí unos retro-cohetes y varios airbags protegerían al aterrizador del impacto contra el suelo. Tras esto comenzaría la fase primaria de toma de datos con una duración estimada de 30 días marcianos o soles. Además el microrover debía moverse por la superficie al menos durante 7 soles. Si pasado este periodo ambos funcionaran correctamente, la NASA ampliaría la misión del aterrizador hasta 1 año y la del microrover durante un mes. LUGAR DE ATERRIZAJE El lugar de aterrizaje de Pathfinder pasó una serie de rigurosos estudios de ingeniería para determinar la seguridad del lugar: suficiente luz solar, pendientes aceptables, poca rugosidad del suelo, baja elevación del polvo para tener la suficiente densidad atmosférica, poco potencial para tormentas, etc. Además debía proporcionar un buen retorno de datos científicos. Finalmente se seleccionó un lugar cerca de la boca de un canal donde se produjo un desbordamiento catastrófico en el pasado en Ares Vallis y que además permitía tener rocas de diferentes tipos en el mismo lugar. Aunque era imposible saber durante la misión el lugar de procedencia de cada roca, el uso de los datos de los orbitadores posteriores pudo ser usado para determinar el camino que siguieron la rocas estudiadas por Pathfinder. La zona de aterrizaje para la nave tenía forma de elipse con una dimensiones de 200 x 70 kilómetros.

Elipse de aterrizaje en Ares Vallis. 19,33º N y 33,55º O ENTRADA, DESCENSO Y ATERRIZAJE La etapa de entrada, descenso y aterrizaje (EDL) para Mars Pathfinder comenzó varios días antes de la llegada a Marte cuando los controladores del JPL enviaron comandos a la nave para decirle cuando y como debía ejecutar las complejas maniobras de la secuencia para llegar a la superficie marciana de una pieza. Este proceso se repite hasta unas horas antes de la llegada para aumentar la precisión del recorrido y los datos enviados, ya que la gravedad marciana sólo es perceptible para la nave las 48 horas previas a la llegada. Desde una hora y media antes del aterrizaje hasta 3 horas y media después, la nave está bajo el control del programa autónomo de abordo que dirige los eventos que ocurrirán. La primera tarea de la nave es hacer circular el líquido de enfriamiento por toda la nave unos 90 minutos antes de la llegada. Este fluido circuló por el perímetro de la etapa de crucero y dentro del aterrizador para mantener los fríos durante los 7 meses de la etapa de crucero. Con su misión cumplida, la etapa de crucero es expulsada media hora antes de la llegada a 8.500 kilómetros de la superficie de Marte. Esta etapa de crucero usaba como combustible para la propulsión hidrazina monopropelante, que hacía funcionar 8 toberas de 4,4 N y proporcionando un delta-V (diferencia de velocidad) de 130 m/s.

Algunos minutos antes de la llegada, la nave comienza a sentir las capas exteriores de la atmósfera a unos 125 kilómetros de altura y quedando ya tan sólo 4 minutos para llegar al suelo. Con el giro estabilizado a 2 revoluciones por minuto y a 7,5 km/s de velocidad, la nave entra en la atmósfera con un ángulo de 14,8º. El escudo térmico derivado de los Viking protege la nave del intenso calor de la reentrada. En el momento de máximo calor, el escudo absorbe más de 100 megavatios de energía termal, de tal manera que la nave baja su velocidad hasta los 400 m/s. La deceleración es superior a los 20 G's y es detectada por los acelerómetros de abordo, lo que provoca que una secuencia de eventos programados comience a funcionar en una rápida sucesión.

Fase completa de entrada y descenso (EDL) El despliegue del paracaidas de 7,5 metros ocurre a los 2 minutos y medio tras la entrada atmosférica a una altura de entre 5 y 11 kilómetros de la superficie bajando la velocidad hasta los 65 m/s. El escudo térmico es separado pirotécnicamente unos 20 segundos más tarde y cae desde una altura entre los 2 y los 9 kilómetros. El aterrizador comienza a separarse del escudo trasero descendiendo en una cuerda de Kevlar de 20 metros de longitud, lo que deja espacio para el inflado de los airbags, una distancia prudente para el encendido de los motores y una estabilidad adicional. Una vez que el aterrizador está en posición se activa el radar altímetro y ayuda en la secuencia de eventos que llegan a continuación (inflado de airbags, encendido de motores del escudo trasero y corte del cable de Kevlar). El radar del aterrizador comenzará a detectar la superficie unos 32 segundos antes del aterrizaje a una altura de 1,5 kilómetros. Los airbags se inflan 8 segundos antes del aterrizaje a 300 metros de altura. Los airbags tienen dos dispositivos explosivos, el primero de los cuales corta los cables y libera las bolsas para que puedan ser infladas. El segundo explosivo se enciende 0,25 segundos después y 4 segundos antes de que se enciendan los cohetes, para activar tres generadores de gas que inflan en 0,3 segundos las tres bolsas de 5,2 metros de diámetro a una presión de poco menos de 1 psi.

Primeras etapas de la entrada El escudo cónico trasero sobre el aterrizador contiene los tres motores de combustible sólido que provocan una fuerza de una tonelada durante dos segundos. El ordenador enciende los motores por unos instantes a una altura de entre 80 y 100 metros del suelo, para que la velocidad sea nula a una altura de 12 metros de la superficie. En ese instante se corta el cable de tal forma que el escudo junto con el paracaidas es lanzado lejos de la zona y el aterrizador envuelto en los airbags cae al suelo. El último impulso de los cohetes debería provocar una gran velocidad lateral al aterrizador, de hasta 25 m/s y un ángulo de 30º para evitar que el paracaidas y el escudo le caigan encima. Tras esto el aterrizador comenzará a botar hasta a 12 metros de altura y recorriendo más de 100 metros entre los botes.

Los retrocohetes frenan la caída y se suelta el airbag que comienza a botar

Tras pararse en la superficie, se activan dispositivos pirotécnicos en los pétalos para que puedan ser abiertos y permitan al aterrizador que comienze su actividad. El aterrizaje ocurrió sobre las 03:00 de la hora local marciana, las 17:07:25 GMT del viernes 4 de julio de 1.997. RETRO-COHETES Los motores de Pathfinder eran esenciales para un aterrizaje seguro. Al ser la atmósfera marciana tan delgada, el paracaidas no podría frenar lo suficiente la nave para evitar que se estrellara. Sin estos cohetes la velocidad de impacto contra el suelo habría sido de 62 m/s y los airbags hubieran reventados junto con la nave. Construidos por la empresa Thiokol, los cohetes apenas tienen una longitud de 90 centímetros pero poseen una gran potencia. De esta forma, en tan sólo 2,4 segundos eran capaces de frenar el descenso y dejar a Pathfinder sin velocidad de caída Durante el instante que son encendidos, podrían generar la suficiente electricidad como para abastecer a una localidad de 15.000 personas. Los gases expulsados llegan a una temperatura de 3.000º C (la mitad de la temperatura de la superficie solar) y una velocidad de 2,6 km/s (10 veces más rápido que un avión de pasajeros). Los tres cohetes son anclados en un estructura que va insertada en el escudo trasero.

Un test de los retrocohetes RETRACCIÓN DE LOS AIRBAGS Y ORIENTACIÓN DEL ROVER Una vez que Mars Pathfinder ha aterrizado en la superficie, se activan los sistemas pirotécnicos en los petalos del aterrizador, de tal manera que permitan su apertura. Las juntas que unen los pétalos laterales son necesarias debido a las fuerzas ejercidas en los pétalos del aterrizador por el sistema de airbags desplegado.

En paralelo con la apertura de los pétalos, un sistema de retracción comenzará a recoger los airbags hacia el aterrizador, practicando una apertura en el lateral de cada bolsa para facilitar el proceso de desinflado a través de un filtro. Los airbags son traídos hacia los pétalos por cables internos que se extienden por las uniones entre los airbags y las pequeñas aberturas en cada una de las caras del aterrizador. El proceso dura unos 64 minutos en desinflar y retraer completamente los airbags.

Hay un motor de giro en cada una de las bisagras de los 3 pétalos. Si el lander aterriza sobre uno de los laterales, será colocado en la posición correcta por la apertura de un pétalo lateral con un motor que colocará el aterrizador en posición vertical. Una vez colocado correctamente se abren los otros dos pétalos.

El proceso de retraer los airbags y desplegar los pétalos del aterrizador dura unas 3 horas en total. Mientras tanto el sistema de radio en banda X del aterrizador es desconectado por primera vez desde el lanzamiento el 4 de diciembre de 1.996. Esto ahorra baterías y permite al sistema electrónico enfriarse tras haberse calentado durante la entrada al no disponer de sistema de enfriamiento. Tras este periodo la Tierra ya es visible bien alta sobre el horizonte y estará en buena posición para comunicarse con el aterrizador a través de la antena de baja ganancia a última hora de la mañana. LA NAVE. EL ATERRIZADOR Y EL ROVER.

El rover Sojourner La masa total del microrover era de 11,5 kilogramos incluyendo el mecanismo de despliegue del APXS y el propio instrumento. Otros 6 kilogramos están situados en el aterrizador como parte del sistema de comunicaciones UHF con el rover, los sistemas de despliegue y de soporte estructural durante el viaje. La altura es de 28 centímetros con una elevación inferior de 13 centímetros sobre el suelo. El espacio dentro del aterrizador para el rover era de tan sólo 20 centímetros por lo que debía viajar con las ruedas plegadas con una altura de tan sólo 18 centímetros. Su longitud total es de 63 centímetros y su anchura de 48 cm.

Esquema del rover. Imagen: Wikipedia Todo el rover es un experimento de tecnología en si mismo, para determinar el rendimiento de los microrovers en el por entonces poco conocido terreno marciano, de forma que permita a las siguientes generaciones de rovers una navegación y movimiento más efectivo en Marte.

El rover Sojourner Tiene tres objetivos principales: 1. Experimentos tecnológicos 2. Experimentos de ciencia con el rover 3. Experimentos de la misión del lander El rover tenía libertad de movimientos respecto al aterrizador y tenía un sistema básico de navegación autónoma usando dos lásers para la detección de obstáculos. Para desplazarse contaba con 6 ruedas autónomas y un sistema de suspensión que permitía sortear pequeñas rocas, viajando a una velocidad máxima de 1 centímetro por segundo. Los datos los enviaba y recibía a través de una antena UHF que conectaba con el aterrizador. Su carga científica constaba de: - Cámara fotográfica trasera a color y doble cámara delantera para imágenes en 3D - Mecanismo de despliegue del APXS - Espectrómetro APXS Para funcionar portaba sobre él un panel solar de 0,25 m2 que proporcionaba un pico de energía de 16 W-hora y una batería con capacidad para 50 W-hora. La temperatura era mantenida en unos límites aceptables gracias a 3 calentadores de radio-isótopos o RHU. El ordenador era un 80C85, con 0,1 MIPS y 0,5 MB de RAM para almacenar datos, todo ello con un peso de 500 gramos y un consumo de 1,5 W. Debido a las limitaciones energéticas, el rover podía funcionar entre las 10 de la mañana y las 2 de la tarde (4 horas en total), de cada sol.

El aterrizador. Carl Sagan Memorial Station. La masa total del conjunto de la misión en el lanzamiento era de 890 kilogramos incluyendo el combustible para el viaje. La masa de entrada en la atmósfera del planeta (sin el módulo de crucero) era de 570 kilogramos y la masa del aterrizador era de 360 kilogramos, incluyendo airbags, paneles y rover. Los objetivos de la Estación Aterrizadora eran varios:

- Permitir al rover llegar hasta la superficie mediante dos rampas de descenso. - Recibir los datos del rover para reenviarlos a la Tierra y enviarle al rover las órdenes de los controladores. - Obtener datos científicos con la estación meteorológica y las cámaras del mástil. El ordenador del aterrizador era un R6000 con un bus VME, con 22 millones de instrucciones por segundo (MIPS) y 128 MB de memoria de almacenamiento. El aterrizador estaba alimentado por paneles solares y las comunicaciones de telemetría se enviaban por la antena de Alta Ganancia (HGA) de banda-X a un ritmo de 6 kb/s a las antenas de 70 metros de la DSN. Para los comandos de operaciones en superficie se usaba la HGA a un ritmo de 250 b/s.

Realización de pruebas de movimiento y comunicaciones en el aterrizador y el rover

El mástil, las antenas y las cámaras SISTEMA DE TELECOMUNICACIONES DEL ROVER El sistema de telecomunicaciones del rover es un sistema en dos direcciones en UHF entre el lander y el rover, usado para enviar comandos desde la Tierra al rover y recibir los datos e imágenes obtenidas. Debido a que el alcance es similar al de un walkie-talkie no es posible la comunicación directa con el rover. Todas las comunicaciones del rover se realizan con la ayuda del sistema de comunicaciones del aterrizador. Está formado por dos radios UHF y dos antenas UHF. La radio está localizada dentro del WEB (Warm Electronic Box) del rover, donde está protegida del frío extremo del ambiente marciano. La radio está conectada a la antena usando un cable coaxial.

Enlaces de comunicación SISTEMA ELÉCTRICO DEL ROVER Panel Solar Toda la energía del rover es proporcionada por un ligero panel solar colocado como un panel plano en la parte superior del rover. El panel es una red de varios cientos de celdas solares muy ligeras y frágiles. La producción al medio día es de unos 16 W, el equivalente a una luz de un horno, pero que permite al rover realizar todas sus actividades científicas.

El panel solar antes de ser instalado Baterías Durante los momentos en los cuales hay muy poca luz solar o ninguna, el rover usaba la electricidad almacenada en las baterías de forma moderada ya que si se descargan por completo ya no hubieran podido ser cargadas de nuevo. Se utilizaron sobretodo para experimentos nocturnos y operaciones a primera hora de la mañana, así como para los chequeos de salud a los que fue sometido durante los 7 meses de crucero hasta la Tierra. INSTRUMENTOS La misión llevaba 3 instrumentos científicos entre el rover y la base:

· Cámara de Mars Pathfinder - Imager For Mars Pathfinder (IMP) · Espectrómetro de Rayos-X Protones Alfa - Alpha Proton X-Ray Spectrometer (APXS) con un Mecanismo de despliegue del APXS. · Instrumentos de Estructura Atmosférica y Meteorología - Atmospheric Structure Instrument/Meteorology Package (ASI/MET)

Imager For Mars Pathfinder (IMP)

La cámara IMP (Imager for Mars Pathfinder) es un sistema de obtención de imágenes en estereo con la posibilidad añadida de captar imágenes en color usando filtros seleccionables en cada una de dos cámaras de las que consta el instrumento. Fue desarrollado por la Universidad de Arizona. El sistema está formado por la cabeza de la cámara (óptica estereo, rueda de filtros, CCDs, preamplificadores y motores de movimiento), el mástil extensible con el cableado y dos tarjetas electrónicas (tarjeta de los datos de CCD y tarjeta de los motores). Tenía un peso de 5,2 kilogramos y gastaba 2,6 Watios.

La cámara IMP Los movimientos en azimut y elevación para la cámara están proporcionados por motores de paso que permiten un movimiento de ±180 grados en azimut y +83/-72 grados en elevación. La cámara está situada en lo más alto del mástil desplegable con una elevación de un metro sobre la superficie del lander. Las imágenes adquiridas son de 256x256 píxeles y es idéntica a la cámara DISR de Huygens. Las dos ruedas llevaban cada una 12 filtros que eran combinados de hasta 30 formas diferentes para obtener las imágenes para observar la atmósfera, elementos geológicos o en estereo. Uno de los filtros era una lente que permitía algunos aumentos para fotografiar imágenes de los imanes que acumulaban el polvo del viento durante la misión y situados en la plataforma de la IMP.

Durante la misión se adquirieron varios panoramas completos de la zona de aterrizaje en color y en estereo. Antes del despliegue del mástil se obtuvo un panorama de 360 grados para luego comparar las distintas perspectivas a las dos alturas.

La cámara en el mástil desplegado Usando las imágenes obtenidas por la cámara se llevaron a cabo investigaciones atmosféricas. La opacidad de los aerosoles se mide realizando fotos del Sol en dos bandas estrechas con dos filtros distintos. Las partículas de polvo en la atmósfera se caracterizaron observando Phobos durante la noche. Además se estudió la abundancia de vapor de agua en la atmósfera con imágenes del Sol en varios filtros en la banda de absorción del agua. Durante algunos soles se fotografiaron los sensores de viento a varias alturas para conocer su dirección y velocidad.

Otra parte de las investigaciones estuvo centrada en las propiedades magnéticas del polvo marciano. Se colocaron imanes de diferente fuerza en una placa acoplada al aterrizador y durante la misión se obtuvieron imágenes para determinar la acumulación de los componentes magnéticos llevados por el polvo marciano. Además las imágenes se obtuvieron con varios filtros para diferenciar los diversos minerales encontrados. Las observaciones también se centraron en un objetivo de referencia para la calibración de las imágenes que portaba un pequeño sensor de viento. Alpha Proton X-Ray Spectrometer

Este instrumento es un derivado directo de los espectrómetros de rayos X que volaron en las misiones rusas Vega y Phobos y es idéntico al que fue usado en la misión Mars 96. Con la movilidad proporcionada por el rover y el sistema de despliegue, el espectrómetro APX no sólo adquirió el espectro del polvo marciano, sino que por primera vez permitió el análisis de distintas rocas de la superficie marciana. El espectrómetro alfa y de protones ha sido proporcionado por el Instituto Max Planck de Alemania y el de rayos X por la Universidad de Chicago. Pesaba 0,74 kilogramos y gastaba 0,8 W.

El APXS en el frontal del rover El instrumento permite conocer la composición elemental de los materiales de las rocas y el suelo utilizando para ello una fuente radiactiva de partículas alfa y detectores de estas partículas, de protones y rayos X que analizaron la energía del espectro devuelto por las muestras. De esta manera se dedujo la composición química elemental de las rocas en todos sus elementos menos el hidrógeno.

Sensores del instrumento El sensor del APXS va montado externo al chasis del rover en un sistema desplegable. Este sistema coloca al APXS en contacto con la roca y el suelo. El resto de la electrónica va en el rover en un sistema de temperatura controlada.

APXS Deployment Mechanism

El sistema de despliegue soporta al APXS bajo las condiciones del lanzamiento y aterrizaje y proporciona los medios necesarios para colocar al APXS en su objetivo con un solo movimiento. El mecanismo es lo bastante flexible como para permitir la colocación del APXS a diversas alturas y orientaciones. Varios mecanismos de contacto en el anillo frontal permiten al rover saber que el aparato se encuentra ya bien posicionado, terminando los movimientos del mecanismo.

El mini-brazo con el APXS en el extremo Atmospheric Structure Instrument/Meterology Package

El ASI/MET es un subsistema de ingeniería que adquiere información atmosférica durante el descenso del aterrizador a través de la atmósfera y durante la misión. Está diseñado por el JPL de sistemas heredados de las misiones Viking. Los datos adquiridos durante la entrada y descenso permitieron la reconstrucción de perfiles de densidad atmosférica, temperatura y presión desde los 100 kilómetros de altura hasta la superficie. Pesaba 2 kilogramos y gastaba 3,2 W.

El ASI consiste en un acelerómetro con sensores en los 3 ejes que permiten conocer los movimientos y fuerzas de aceleración durante la entrada y los eventos del aterrizaje, hasta los 50 G's. Entre los instrumentos se encuentran sensores de temperatura, presión y viento, así como la electrónica necesaria para los sensores y el tratamiento digital de los datos obtenidos. La temperatura es medida por termopares montados en un mástil que se despliega tras el aterrizaje. Uno de ellos permite conocer la temperatura durante el descenso y otros tres están colocados a 25, 50 y 100 cm del suelo en la misión.

ASI/MET con los sensores de temperatura y viento Tres sensores de viento están colocados a varias alturas del mástil para determinar las velocidades y direcciones del viento en la zona de aterrizaje. Este sensor fue muy fotografiado por la cámara IMP durante la misión. De esta manera es posible conocer la orientación de los alerones para determinar la dirección y velocidad del viento a las 3 alturas, permitiendo la obtención de perfiles verticales del viento.

Lunar/Planetary Events The Mars Pathfinder was the second of NASA's low-cost Rocky IV planetary Discovery missions to be launched. The mission MFEX consists of a stationary lander and a surface rover. The mission had the primary objective of demonstrating the Microrover Flight feasibility of low-cost landings on and exploration of the Experiment Martian surface. This objective was met by tests of MESUR Pathfinder Rover communications between the rover and lander, and the lander Sojourner and Earth, tests of the imaging devices and sensors, and tests of the maneuverability and systems of the rover on the surface. The scientific objectives include atmospheric entry Facts in Brief science, long-range and close-up surface imaging, rock and soil composition and material properties experiments, and Launch Date: 1996-12- meteorology, with the general objective being to characterize 04 Launch Vehicle: Delta Mars Pathfinder Rover the Martian environment for further exploration. (Mars Pathfinder was formerly known as the Mars Environmental II Survey (MESUR) Pathfinder.) Launch Site: Cape Canaveral, United States The rover, which has been named "Sojourner" is a six-wheeled Mass: 10.5 kg vehicle, 280 mm high, 630 mm long, and 480 mm wide with a Nominal Power: 13.0 W ground clearance of 130 mm, mounted on a "rocker-bogie" suspension. The rover was stowed on the lander at a height of Funding Agency 180 mm. At deployment, the rover extended to its full height and rolled down a deployment ramp at about 05:40 UT on 6 NASA-Office of Space July 1997 (1:40 a.m. EDT). The rover was controlled by an Science (United States) Earth-based operator who used images obtained by both the rover and lander systems. Note that the time delay was between 10 and 15 minutes depending on the relative position Discipline of Earth and Mars over the course of the mission, requiring Planetary Science some autonomous control, provided by a hazard avoidance system on the rover. The on-board control system is an Intel 80C85 8-bit processor which runs about 100,000 instructions Additional per second. The computer is capable of compressing and Information storing a single image on-board. The rover is powered by 0.2 square meters of solar cells, which will provide energy for Launch/Orbital several hours of operations per sol (1 Martian day = 24.6 Earth information for Mars hours). Non-rechargeable lithium thionyl chloride (LiSOCl2) D- Pathfinder Rover cell batteries provide backup. All rover communications were PDMP information for done through the lander. Mars Pathfinder Rover Telecommunications The rover is equipped with black and white and color imaging information for Mars systems which were used to image the lander in order to Pathfinder Rover assess its condition after touchdown. The goal was to acquire three black and white images spaced 120 degrees apart of the Experiments on Mars lander.

An alpha- proton-X-ray spectrometer (APXS) is on-board the rover to assess the composition of rocks and soil. Images of all samples tested are transmitted to Earth. The primary objectives were scheduled for the first seven sols, all within about 10 meters of the lander. The extended mission included slightly longer trips away from the lander, and even longer journeys were planned. Images were taken and experiments performed by the lander and rover until 27 September 1997 when communications were lost for unknown reasons.

The landing site in the Ares Vallis region of Mars is at 19.33 N, 33.55 W. The lander has been named the Sagan Memorial Station. The Ares Vallis region of Mars is a large outwash plain near Chryse Planitia. This region is one of the largest outflow channels on Mars, the result of a huge flood (possibly an amount of water equivalent to the volume of all five Great Lakes) over a short period of time flowing into the martian northern lowlands.

The Mars Pathfinder mission cost approximately $265 million including launch and operations. Development and construction of the lander cost $150 million and the rover about $25 million.

Lunar/Planetary Events The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Near Earth Asteroid Shoemaker), renamed in honor of Gene Shoemaker, was Rendezvous designed to study the near Earth asteroid Eros from close orbit NEAR over a period of a year. The mission was the first-ever to orbit an asteroid and to touch down on the surface of an asteroid. 23784 The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, Facts in Brief internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith properties, Launch Date: 1996-02- interactions with the solar wind, possible current activity as 17 indicated by dust or gas, and the asteroid spin state. This data Launch Vehicle: Delta NEAR Shoemaker will be used to help understand the characteristics of asteroids II 7925 in general, their relationship to meteorites and comets, and the Launch Site: Cape conditions in the early solar system. To accomplish these Canaveral, United States goals, the spacecraft is equipped with an X-ray/gamma ray Mass: 487.0 kg spectrometer, a near infrared imaging spectrograph, a multi- Nominal spectral camera fitted with a CCD imaging detector, a laser Power: 1800.0 W rangefinder, and a magnetometer. A radio science experiment was also performed using the NEAR tracking system to estimate the gravity field of the asteroid. The total mass of the Funding Agency instruments is 56 kg, and they require 81 W power. NASA-Office of Space Science Applications Mission Profile (United States) The ultimate goal of the mission was to study the near Earth asteroid 433 Eros from orbit for approximately one year. Eros is an S-class asteroid approximately 13 x 13 x 33 km in size, Disciplines the second largest near-Earth asteroid. Initially the orbit was circular with a radius of 200 km. The radius of the orbit was Planetary Science brought down in stages to a 50 x 50 km orbit on 30 April 2000 Space Physics and decreased to 35 x 35 km on 14 July 2000. The orbit was raised over succeeding months to a 200 x 200 km orbit and then slowly decreased and altered to a 35 x 35 km retrograde Additional orbit on 13 December 2000. The mission ended with a Information touchdown in the "saddle" region of Eros on 12 February 2001. Launch/Orbital information for NEAR After launch on a Delta 7925-8 (a Delta II Lite launch vehicle Shoemaker with nine strap-on solid-rocket boosters and a Star 48 (PAM-D) third stage) and exit from Earth orbit, NEAR entered the first PDMP information for part of its cruise phase. It spent most of this phase in a NEAR Shoemaker minimal activity "hibernation" state, which ended a few days Telecommunications before the flyby of the 61 km diameter asteroid 253 Mathilde information for NEAR on June 27, 1997. The spacecraft flew within 1200 km of Shoemaker Mathilde at 12:56 UT at 9.93 km/sec, returning imaging and other instrument data. On July 3, 1997 NEAR executed the Experiments on NEAR first major deep space maneuver, a two-part burn of the main Shoemaker 450 Newton thruster. This decreased the velocity by 279 m/sec and lowered perihelion from 0.99 AU to 0.95 AU. The Data collections from Earth gravity assist swingby occurred on January 23, 1998 at NEAR Shoemaker 7:23 UT. The closest approach was 540 km, altering the orbital http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1996-008A[08/06/2011 23:25:37] NASA - NSSDC - Spacecraft - Details

inclination from 0.5 to 10.2 degrees, and the aphelion distance from 2.17 to 1.77 AU, nearly matching those of Eros. Instrumentation was active at this time. Questions or comments about this spacecraft can The first of four scheduled rendezvous burns on 20 December be directed to: Dr. David R. 1998 at 22:00 UT aborted due to a software problem. Contact Williams. was lost immediately after this and was not re-established for over 24 hours. The original mission plan called for these four burns to be followed by an orbit insertion burn on 10 January 1999, but the abort of the first burn and loss of communication made this impossible. A new plan was put into effect in which NEAR flew by Eros on 23 December 1998 at 18:41:23 UT at a speed of 0.965 km/s and a distance of 3827 km from the center of mass of Eros. Images of Eros were taken by the camera, data was collected by the near IR spectrograph, and radio tracking was performed during the flyby. A rendezvous maneuver was performed on 3 January 1999 involving a thruster burn to match NEAR's orbital speed to that of Eros. A hydrazine thruster burn took place on 20 January to fine-tune the trajectory. On 12 August a 2 minute thruster burn slowed the spacecraft velocity relative to Eros to 300 km/hr.

Orbit insertion around Eros occurred on 14 February 2000 at 15:33 UT (10:33 AM EST) after NEAR completed a 13 month heliocentric orbit which closely matched the orbit of Eros. A rendezvous maneuver was completed on 3 February at 17:00 UT, slowing the spacecraft from 19.3 to 8.1 m/s relative to Eros. Another maneuver took place on 8 February increasing the relative velocity slightly to 9.9 m/s. Searches for satellites of Eros took place on 28 January, and 4 and 9 February, none were found. The scans were for for scientific purposes and to mitigate any chances of collision with a satellite. NEAR went into a 321 x 366 km orbit around Eros on 14 February. The orbit was slowly decreased to a 35 km circular polar orbit by 14 July. NEAR remained in this orbit for 10 days and then was backed out in stages to a 100 km circular orbit by 5 September 2000. Maneuvers in mid-October led to a flyby of Eros within 5.3 km of the surface at 07:00 UT on 26 October.

Following the flyby NEAR moved to a 200 km circular orbit and shifted the orbit from prograde near-polar to a retrograde near- equatorial orbit. By 13 December 2000 the orbit was be shifted back to a circular 35 km low orbit. where NEAR will remain until the nominal end of mission on 12 February 2001. Starting on 24 January 2001 the spacecraft began a series of close passes (5 to 6 km) to the surface and on 28 January passed 2 to 3 km from the asteroid. The spacecraft made a slow controlled descent to the surface of Eros ending with a touchdown in the "saddle" region of Eros on 12 February 2001 at 20:01:52 UT (3:01:52 p.m. EST). This was the first spacecraft touchdown on an asteroid. After landing, the spacecraft continued to operate until the final contact was made on 28 February. The gamma-ray spectrometer collected data from the asteroid's surface over this time. A later attempt to contact the spacecraft on 10 December 2002 was unsuccessful.

Spacecraft and Subsystems The spacecraft has the shape of an octagonal prism, approximately 1.7 m on a side, with four fixed gallium arsenide solar panels in a windmill arrangement, a fixed 1.5 m X-band high-gain radio antenna with a magnetometer mounted on the antenna feed, and an X-ray solar monitor on one end (the forward deck), with the other instruments fixed on the opposite end (the aft deck). Most electronics are mounted on the inside of the decks. The propulsion module is contained in the interior.

The craft is three-axis stabilized and uses a single bipropellant

(hydrazine / nitrogen tetroxide) 450 Newton (N) main thruster, and four 21 N and seven 3.5 N hydrazine thrusters for propulsion, for a total delta-V potential of 1450 m/s. Attitude control is achieved using the hydrazine thrusters and 4 reaction wheels. The propulsion system carries 209 kilograms of hydrazine and 109 kilograms of NTO oxidizer in two oxidizer and three fuel tanks.

Power is provided by four 1.8 by 1.2 meter gallium arsenide solar panels which can produce 400 W at 2.2 AU (NEAR's maximum distance from the Sun) and 1800 W at 1 AU. Power is stored in a 9 amp-hour, 22-cell rechargeable super nickel- cadmium battery.

Spacecraft guidance is achieved through the use of a sensor suite of five digital solar attitude detectors, an inertial measurement unit, (IMU) and a star tracker camera pointed opposite the instrument pointing direction. The IMU contains hemispherical resonator gyros and accelerometers. Four reaction wheels (arranged so that any three can provide complete three-axis control) are used for normal attitude control. The thrusters are used to dump angular momentum from the reaction wheels, as well as for rapid slew and propulsive maneuvers. Attitude control is to 0.1 degree, line-of- sight pointing stability is within 50 microradians over 1 second, and post-processing attitude knowledge is to 50 microradians.

The command and data handling subsytem is composed of two redundant command and telemetry processors and solid state recorders, a power switching unit, and an interface to two redundant 1553 standard data buses for communications with other subsystems. The solid state recorders are constructed from 16 Mbit IBM Luna-C DRAMs. One recorder has 1.1 Gbits of storage, the other has 0.67 Gbits.

The NEAR mission was the first launch of NASA's Discovery program, a series of small-scale spacecraft designed to proceed from development to flight in under three years for a cost of less than $150 million. The total cost of the mission was $220.5 million, which included $43.5 million for the launch vehicle and $60.8 million for mission operations after launch.

NEAR (Near Earth Asteroid Rendezvous) was a mission to rendezvous and orbit around an near earth asteroid (433 Eros). On the cruise to Eros, it flew by asteroid 253 Mathilde on 27 Jun 1997 and flew by earth on 23 January 1998. After failing to insert itself into Eros' orbit in January 1999, NEAR finally inserted itself into orbit around the asteroid on the second try on 14 February NEAR [NASA] 2000. Initially in a 323 km x 370 km orbit, it lowered its altitude during observation. After reaching orbit, NEAR was renamed NEAR-Shoemaker.

After completing its one year mission, NEAR Shoemaker gently landed on the tips of two solar panels and its bottom edge on February 12, 2001. The spacecraft snapped 69 detailed pictures during the final 5 km of its descent, the highest resolution images ever obtained of an asteroid, showing features as small as one centimeter across. The slow touchdown speed left the spacecraft intact and still sending a signal back to Earth. NASA decided to extend the mission to February 28th, to get "bonus science" from the spacecraft, which had already collected 10 times more data than originally planned. This allowed the gamma-ray spectrometer to collect data from an ideal vantage point about four inches (10 cm) from the surface

The primary scientific goals were to measure the asteroid's:

bulk properties (size, shape, volume, mass, gravity field, and spin state); surface properties (elemental and mineral composition, geology, morphology, and texture); internal properties (mass distribution and magnetic field).

Science instruments:

MultiSpectral Imager (MSI) - a refractive telescope with passively cooled Si CCD array (244 x 537) that will determine the overall size, shape, and spin characteristics of the asteroid, map the morphology and composition of the surface, and search for satellites of Eros.2.25 x 2.9 deg FOV, 10-16 meter resolution from 100 km altitude, sensitive between 400 and 1100 nm. X-Ray/Gamma-Ray Spectrometer (XGRS) - containing two sensors (an X-ray fluorescence spectrometer and a gamma-ray spectrometer), XGRS will be used to determining the surface/near-surface elemental composition of the asteroid. Near-Infrared Spectrograph (NIS) - a spectrometer covering 800-2700 nm, NIS is designed to map the mineralogical composition of Eros. Magnetometer - a three-axis fluxgate sensor that will be used to measure Eros' magnetic field. These measurements will help determine the internal composition of the asteroid. NEAR Laser Rangefinder (NLR) - an altimeter that uses a solid-state pulsed laser to measure the distance between the spacecraft and the surface of the asteroid. It will be used to make will make accurate measurements of the asteroid's shape and detailed surface structure. Nd-YAG laser operating at 1.064 mm wavelength, 6 meter resolution, 50 km range. Radio Science - uses the satellite's telemetry system to map Eros' gravity field.
