  • Tianwen-1: China's Mars Mission
    Tianwen-1: China's Mars Mission drishtiias.com/printpdf/tianwen-1-china-s-mars-mission Why In News China will launch its first Mars Mission - Tianwen-1- in July, 2020. China's previous ‘Yinghuo-1’ Mars mission, which was supported by a Russian spacecraft, had failed after it did not leave the earth's orbit and disintegrated over the Pacific Ocean in 2012. The National Aeronautics and Space Administration (NASA) is also going to launch its own Mars mission in July, the Perseverance which aims to collect Martian samples. Key Points The Tianwen-1 Mission: It will lift off on a Long March 5 rocket, from the Wenchang launch centre. It will carry 13 payloads (seven orbiters and six rovers) that will explore the planet. It is an all-in-one orbiter, lander and rover system. Orbiter: It is a spacecraft designed to orbit a celestial body (astronomical body) without landing on its surface. Lander: It is a strong, lightweight spacecraft structure, consisting of a base and three sides "petals" in the shape of a tetrahedron (pyramid- shaped). It is a protective "shell" that houses the rover and protects it, along with the airbags, from the forces of impact. Rover: It is a planetary surface exploration device designed to move across the solid surface on a planet or other planetary mass celestial bodies. 1/3 Objectives: The mission will be the first to place a ground-penetrating radar on the Martian surface, which will be able to study local geology, as well as rock, ice, and dirt distribution. It will search the martian surface for water, investigate soil characteristics, and study the atmosphere.

The series features two anthropomorphic characters depicting the Rosetta orbiter and Philae lander, introducing the mission story, goals and milestones with a fairy- tale flair.

  • Exomars Trace Gas Orbiter Operations ESOC
    Training Opportunity for Swiss Trainees Reference Title Duty Station CH-2019-OPS-OPE Exomars Trace Gas Orbiter operations ESOC Overview of the unit’s mission: OPS-OP is responsible for mission preparation and flight operations for the ESA fleet of solar and interplanetary spacecraft. The division currently operates four missions (Cluster, Mars Express, ExoMars TGO, Bepi Colombo) and prepares for the launch of three others (Solar Orbiter, ExoMars Rover and Surface Platform, JUICE). Within OPS-OP, the ExoMars TGO unit (OPS-OPE) is responsible for the operations of the Trace Gas Orbiter (TGO) in-orbit around Mars. This includes monitoring, control and mission planning of the satellite as well as the mission responsibility for the required data systems and related interfaces. Overview of the field of activity proposed: The ExoMars TGO is the first in a series of Mars missions undertaken jointly by ESA and Roscosmos. From its 400-km- altitude science orbit TGO shall gain a better understanding of methane and other atmospheric gases present in small concentrations (less than 1% of the atmosphere) which could be evidence for possible biological or geological activity. The Orbiter is also an invaluable Mars telecommunications asset, currently providing communication services to NASA rovers (or landers) on the Mars Surface: it acts as a data relay hub for sending commands to the rovers and downloading rover data to Earth using ESA, NASA and Russian space communication networks. This relay function will serve the ExoMars 2020 mission, combining a European Rover and a Russian science Surface Platform, planned to land on Mars in March 2021.

  • Balloon Powered Phoenix Mars Lander Model (Simplified Version)
    balloon powered Phoenix Mars Lander Model (simplified version) by Steve Widmark Mountain View High School, Mountain View, CA What is Phoenix? Phoenix is NASA’s latest mission to Mars. Launched on a Delta II rocket on August 4 th , 2007, the Phoenix lander will touch down in the northern region of Mars on May 25, 2008. Once there, it will dig into the Martian permafrost using a robotic arm and analyze the composition of the soil and ice it removes with a sophisticated automated laboratory. In a nutshell, the goal of the mission is to determine if the Martian surface is (or was) capable of supporting life. Unlike the previous rover missions to Mars that made bounce landings using air bags, Phoenix will make a powered landing employing twelve thrusters positioned around the spacecraft. The model demonstrates this method of landing with a single balloon “thruster.” For more information about the Phoenix mission go to http://phoenix.lpl.arizona.edu Materials and tools: 1 parts sheet color printed on 110 lb (#110) card stock 1 balloon (lander flies best with a 5” balloon) 1 small paper clip clear tape glue sick or white glue scissors pencil Directions: Note: If the directions tell you to bend a tab down, this means to bend the tab down with the printed portion of the part facing up. If the directions tell you to bend a tab up, this means to bend the tab up with the printed portion of the part facing up. The front side of a part is the side with the printing.

  • ROVING ACROSS MARS: SEARCHING for EVIDENCE of FORMER HABITABLE ENVIRONMENTS Michael H
    PERSPECTIVE ROVING ACROSS MARS: SEARCHING FOR EVIDENCE OF FORMER HABITABLE ENVIRONMENTS Michael H. Carr* My love affair with Mars started in the late 1960s when I was appointed a member of the Mariner 9 and Viking Orbiter imaging teams. The global surveys of these two missions revealed a geological wonderland in which many of the geological processes that operate here on Earth operate also on Mars, but on a grander scale. I was subsequently involved in almost every Mars mission, both US and non- US, through the early 2000s, and wrote several books on Mars, most recently The Surface of Mars (Carr 2006). I also participated extensively in NASA’s long-range strategic planning for Mars exploration, including assessment of the merits of various techniques, such as penetrators, Mars rovers showing their evolution from 1996 to the present day. FIGURE 1 balloons, airplanes, and rovers. I am, therefore, following the results In the foreground is the tethered rover, Sojourner, launched in 1996. On the left is a model of the rovers Spirit and Opportunity, launched in 2004. from Curiosity with considerable interest. On the right is Curiosity, launched in 2011. IMAGE CREDIT: NASA/JPL-CALTECH The six papers in this issue outline some of the fi ndings of the Mars rover Curiosity, which has spent the last two years on the Martian surface looking for evidence of past habitable conditions. It is not the fi rst rover to explore Mars, but it is by far the most capable (FIG. 1). modest-sized landed vehicles. Advances in guidance enabled landing Included on the vehicle are a number of cameras, an alpha particle at more interesting and promising places, and advances in robotics led X-ray spectrometer (APXS) for contact elemental composition, a spec- to vehicles with more independent capabilities.

JSC-RN was designed to be chemically and mineralogically similar to material from the 25 aeolian sand shadow named Rocknest in Gale Crater, particularly the 1-3 wt.% low temperature 26 (<450 ºC) water release as measured by the Sample Analysis at Mars (SAM) instrument on the 27 Curiosity rover. Sodium perchlorate, goethite, pyrite, ferric sulfate, regular and high capacity 28 granular ferric oxide, and forsterite were added to a Mojave Mars Simulant (MMS) base in order 29 to match the mineralogy, evolved gases, and elemental chemistry of Rocknest.
