Introduction: The icy satellites of Jupiter and horizontal stresses, respectively, Pp is pore fluid Saturn have been the subjects of substantial geological pressure (found from (3)), and μ is the coefficient of study. Much of this work has focused on their outer friction [12]. Finally, because equations (4) and (5) shells [e.g., 1–3], because that is the part most readily assess failure in the brittle domain, we also considered amenable to analysis. Yet many of these satellites ductile deformation with the relation n –E/RT feature known or suspected subsurface oceans [e.g., 4– ε̇ = C1σ exp , (6) 6], likely situated atop rocky interiors [e.g., 7], and where ε̇ is strain rate, C1 is a constant, σ is deviatoric several are of considerable astrobiological significance. stress, n is the stress exponent, E is activation energy, R For example, chemical reactions at the rock–water is the universal gas constant, and T is temperature [13]. -
Solar-Wind Proton Access Deep Into the Near-Moon Wake M

[1] We study solar wind (SW) entry deep into the near- wake were not known because there were no observation Moon wake using SELENE (KAGUYA) data. It has been data. Recently, a Japanese lunar orbiter SELENE known that SW protons flowing around the Moon access (KAGUYA) performed comprehensive measurements of the central region of the distant lunar wake, while their the plasma and electromagnetic environment around the intrusion deep into the near-Moon wake has never been Moon; in particular, entry of SW protons into the near- expected. We show that SW protons sneak into the deepest Moon wake was found [Nishino et al., 2009]. The SW lunar wake (anti-subsolar region at 100 km altitude), and protons are accelerated by the bipolar electric field around that the entry yields strong asymmetry of the near-Moon the wake boundary and come into the near-Moon wake by wake environment. Particle trajectory calculations their Larmor motion in the direction perpendicular to the demonstrate that these SW protons are once scattered at IMF. This entry mechanism, which we call ‘Type-I entry’, the lunar dayside surface, picked-up by the SW motional lets the SW protons come fairly deep into the wake (solar electric field, and finally sneak into the deepest wake. -

Schulz and his American icon Snoopy since Apollo missions began in the 1960s. Schulz created comic strips depicting Snoopy on the Moon, capturing public excitement about America’s achievements in space. In May 1969, Apollo 10 astronauts traveled to the Moon for a final trial run before the lunar landings took place on later missions. Because that mission required the lunar module to skim within 50,000 feet of the Moon’s surface and “snoop around” to determine the landing site for Apollo 11, the crew named the lunar module Snoopy. The command module was named Charlie Brown, after Snoopy’s loyal owner. These books are a united effort between Peanuts Worldwide, NASA and Simon & Schuster to generate interest in space among today’s younger children. -
Exploration of the Moon
Exploration of the Moon The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it. NASA's Apollo program was the first, and to date only, mission to successfully land humans on the Moon, which it did six times. The first landing took place in 1969, when astronauts placed scientific instruments and returnedlunar samples to Earth.

Contents Early history Space race Recent exploration Plans Past and future lunar missions See also References External links Early history The ancient Greek philosopher Anaxagoras (d. 428 BC) reasoned that the Sun and Moon were both giant spherical rocks, and that the latter reflected the light of the former. His non-religious view of the heavens was one cause for his imprisonment and eventual exile.[1] In his little book On the Face in the Moon's Orb, Plutarch suggested that the Moon had deep recesses in which the light of the Sun did not reach and that the spots are nothing but the shadows of rivers or deep chasms. -
The Subsurface Habitability of Small, Icy Exomoons J

S. van der Tak1,2 1 Kapteyn Astronomical Institute, University of Groningen, Landleven 12, 9747 AD Groningen, The Netherlands e-mail: [email protected] 2 SRON Netherlands Institute for Space Research, Landleven 12, 9747 AD Groningen, The Netherlands 3 Leiden Observatory, Leiden University, Niels Bohrweg 2, 2300 RA Leiden, The Netherlands Received 1 November 2019 / Accepted 8 March 2020 ABSTRACT Context. Assuming our Solar System as typical, exomoons may outnumber exoplanets. If their habitability fraction is similar, they would thus constitute the largest portion of habitable real estate in the Universe. Icy moons in our Solar System, such as Europa and Enceladus, have already been shown to possess liquid water, a prerequisite for life on Earth. Aims. We intend to investigate under what thermal and orbital circumstances small, icy moons may sustain subsurface oceans and thus be “subsurface habitable”. We pay specific attention to tidal heating, which may keep a moon liquid far beyond the conservative habitable zone. Methods. We made use of a phenomenological approach to tidal heating. We computed the orbit averaged flux from both stellar and planetary (both thermal and reflected stellar) illumination. We then calculated subsurface temperatures depending on illumination and thermal conduction to the surface through the ice shell and an insulating layer of regolith. We adopted a conduction only model, ignoring volcanism and ice shell convection as an outlet for internal heat. -
Misiones Espaciales Misiones Que Año Nación Lanzador Síntesis De La Misión Recorrido Lo Visitaron
Una vez finalizada la Segunda Guerra Mundial, Estados Unidos y la Unión Soviética se enfrentaron ideológica y políticamente. El campo de batalla de los dos bloques fue llamado Guerra fría. Las dos super potencias se embarcaron en una carrera por la conquista del espacio en un despliegue de poderío científico, militar y tecnológico. En un comienzo los mayores éxitos fueron de la URSS pero fue EE UU el que logró llevar seres humanos a la Luna. Luego de ese suceso, pasaron varios años hasta que otros países lograron el sueño de llegar a nuestro satélite. LMiUNsiones espacAiales En la actual carrera espacial ingresan nuevos proyectos financiados de manera privada.

James A. Lovell, Jr., Commander... Fred W. Haise, Jr., Lunar Module Pilot... John L. Swigeft, Jr., Command Module Pilot. SPACECRAFT--Hey, we've got a problem here. Thus, calmly, Command Module Pilot JackSwigert gave the first intimation of serious trouble for Apollo 13--200,000miles from Earth. CAPSULECOMMUNICATOR--ThisisHouston;say again, please. SC--Houston, we've hada problem. We've hada MainBbusundervolt. By "undervolt"Swigert meant a drop in power in one of the Command/Service Module's two main electrical circuits. His report to the ground began the most grippingepisode in man's venture into space. One newspaper reporter called it the most public emergency and the most dramatic rescue in the history of exploration. SC--Andwe hada pretty large bang associatedwith the cautionandwarning here. Lunar Module Pilot Fred Haise was now on the voice channel from the spacecraft to the Mission Control Center at the National Aeronautics and Space Administration's Manned Spacecraft Center in Texas. Commander Jim Lovell would shortly be heard, then again Swigert--the backup crewman who had been thrust onto the first team only two days before launch when doctors feared that Tom Mattingly of the primary crew might come down with German measles. Equally cool, the men in Mission Control acknowledged the report and began the emergency procedures that grew into an effort by hundreds of ground controllers and thousands of technicians and scientists in NaSA contractor plants and On university campuses to solve the most complexand urgent problem yet encountered in space flight. -
