Mars Introduction Mars is the fourth planet from the Sun and is commonly referred to as the Red Planet. The average recorded temperature on Mars is -63° C (-81° F) with a maximum temperature of 20° C (68° F) and a minimum of -140° C (-220° F). One of the discoveries of the Mariner 9 spacecraft was that the south polar cap of Mars was made of thin layers or laminations of ice and sediment. www.solarviews.com /eng/mars.htm   (2575 words)

TPS: Exploring Mars: Past Missions to Mars   (Site not responding. Last check: 2007-09-09) Then, on September 3, 1976, the Viking 2 lander separated from the orbiter and touched down in the Utopia Planitia, on the opposite side of the planet and almost 1,500 kilometers closer to the north pole than Viking 1 (at roughly 47.27 degrees north, 225.99 degrees west). Mars Climate Orbiter was lost on September 23, 1999, when a mathematical conversion error placed the spacecraft too close to Mars at the time of orbital insertion. Mars Reconnaissance Orbiter, scheduled for launch in August 2005, will search for evidence that water persisted on the surface of Mars for a long period of time using a large and powerful suite of instruments. www.planetary.org /mars/missions-past.html   (2776 words)

Mars 3 - Wikipedia, the free encyclopedia The Mars 3 orbiter sent back a large volume of data covering the period from December 1971 to March 1972, although transmissions continued through August. Mars 3's descent module was released at 09:14 UT on December 2, 1971, 4 hours 35 minutes before reaching Mars. Mars 3 lander had a small 4.5 kg Mars 'rover' on board, which would move across the surface on skis while connected to the lander with a 15-meter umbilical. en.wikipedia.org /wiki/Mars_3   (888 words)

NSSDC Master Catalog Display: Spacecraft   (Site not responding. Last check: 2007-09-09) The primary scientific objective of the Mars 3 descent module was to perform a soft landing on Mars, return images from the surface, and return data on meteorological conditions, atmospheric composition, and mechanical and chemical properties of the soil. The Mars 2 and 3 landers carried a small walking robot called PROP-M. The robot had a mass of 4.5 kg and was tethered to the lander by a cable for direct communication. Mars 3 impacted the surface at a reported 20.7 m/s at approximately 45 degrees S, 158 degrees W, at 13:50:35 UT. Shock absorbers inside the capsule were designed to prevent damage to the instruments. nssdc.gsfc.nasa.gov /database/MasterCatalog?sc=1971-049F   (872 words)

Space Missions It flew past Mars at 2,200 km range and was able to return one swath of images and data on the ionosphere of Mars. Unfortunately, Mars 5 was suppose to serve as relay transmitters for landers 6 and 7. Its science objectives are to complete a high resolution mapping of the surface, study the topography and gravity of Mars, assess the role of water and dust on the surface and in the atmosphere of Mars, and determine the existence and evolution of the Martian magnetic field. www.windows.ucar.edu /tour/link=/mars/space_missions.html   (1030 words)

Facing Phobos :: Mars Astrobiology Magazine :: Search for Life on Mars Twin NASA rovers and one European Space Agency probe are planned for Mars landing in late 2003 and early 2004. Dust is confirmed as the dominant absorber of Solar radiation in Mars' atmosphere, which has important consequences for the transport of energy in the atmosphere and its circulation. The moment of inertia of Mars was refined to a corresponding core radius of between 807 miles and 1,242 miles (1,300 and 2,000 kilometers). mars.astrobio.net /news/article95.html   (1199 words)

What About Mars? Mars is a little farther from the Sun -- an average of 52% farther, at 227,920,000 km. The martian atmosphere is 95% carbon dioxide and 3% nitrogen. On December 2, 1971, the Mars 3 lander was the first spacecraft to land on Mars. xpda.com /mars   (2899 words)

TPS: Exploring Mars   (Site not responding. Last check: 2007-09-09) Previous descriptions of Mars 2 and 3 omitted mention of the small vehicles that were attached to the main landers by tethers. Mars 2, although it crashed, holds the distinction of being the first human-made object to reach the surface of Mars. Mars 2 and 3 was launched May 19, 1971 and reached the Red Planet on November 27. www.planetary.org /mars/tpr_rover-rus_first-rover.html   (599 words)

Space Today Online - Exploring the Red Planet - Past Mars Probes Mars 2 and Mars 3 were identical spacecraft – each an orbiter with attached descent module. Both Mars 2 and Mars 3 arrived in orbit over the Red Planet and dropped their descent modules, which were decorated with USSR flags. The four petals covering the Mars 3 lander opened and, 90 seconds later, the capsule began transmitting to the Mars 3 orbiter. www.spacetoday.org /SolSys/Mars/MarsExploration/MarsProbesPast.html   (1541 words)

Mars   (Site not responding. Last check: 2007-09-09) The Mars Global Surveyor Spacecraft has detected traces of residual magnetic fields trapped in parts of the crust suggesting that Mars once had a magnetic field and presumably a molten iron core. Mars’ crust was battered during heavy hits from the last of debris in the young solar system has swept up. Because it was not preprogrammed ad the Mars 2 and Mars 3 orbiters were, it was able to wait out the dust storm. faculty.icc.edu /lkellerman/projects_04/mars.htm   (1612 words)

Mars Exploration: Missions Mariner 3 and 4 were identical spacecraft designed to carry out the first flybys of Mars. Mariner 3 was launched on November 5, 1964, but the shroud encasing the spacecraft atop its rocket failed to open properly, and Mariner 3 did not get to Mars. The Mariner 4 spacecraft was not expected to survive much longer than the eight months to its Mars flyby encounter, but actually lasted about three years in solar orbit, continuing long-term studies of the solar wind environment and making coordinated measurements with Mariner 5, a sister ship launched to Venus in 1967. mars.jpl.nasa.gov /missions/past/mariner3-4.html   (276 words)

Soviet Mars Images Soviet Mars probes in the 1960s were far ahead of their time but suffered a series of unlucky failures. The original plan was to spend the first 40 days performing photographic surveys; however, Mars was experiencing a severe planet-wide dust storm when the Soviet probes (and the American Mariner-9) arrived. These were very similar to cameras later flown on Venera-9 and 10 orbiters, but one of the Mars versions had a photomultiplier tube sensitive to infrared. www.mentallandscape.com /C_CatalogMars.htm   (960 words)

Missions to Mars: Past, Present and Future The orbiter took no useful pictures as Mars was in the midst of a global dust storm and the orbiter's picture taking sequence had been preprogrammed. A combination orbiter and lander destined for the moon Phobos, the craft arrived at Mars and returned data until contact was lost on 03/27/1989 prior to releasing its lander. Also known as the Mars Surveyor 98 Orbiter, this orbiter mission was entering Mars orbit but crashed to the surface as a result of a misunderstanding over English vs Metric units. www.astrodigital.org /mars/mission_past.html   (948 words)

ESA - Mars Express - Voyages to Mars Mars 2 arrived and entered orbit and released a lander, but this crashed on the surface after its breaking rockets failed - although it did become the first man-made object on Mars. Mars Global Surveyor became the first successful mission to the Red Planet in twenty years when it was launched in 1996, entering orbit in 1997. The Russian Mars ’96 orbiter and landers, carrying several European experiments, were lost in launch vehicle accident in 1996. www.esa.int /export/SPECIALS/Mars_Express/SEMGF2374OD_0.html   (807 words)

CNN.com - No news is bad news from Mars - Dec. 25, 2003 An attempt earlier in the day, by the U.S. Mars Odyssey already in orbit, was not able to detect the probe's signal on its first pass over the landing site, AP reports. Scientists were earlier hopeful the British-built Beagle 2 had landed on Mars, despite being unable to receive a signal to confirm the probe's touchdown. The mini-lander hitched a six-month ride to the red planet with the Mars Express, which last Friday dispatched Beagle 2 on its way to Isidis Planitia, Martian lowlands in a basin that may have contained water several billion years ago, when the planet was thought to have been warmer and wetter. edition.cnn.com /2003/TECH/space/12/25/mars.beagle.nosignal/index.html   (829 words)

CNN - NASA unveils first 3-D map of Mars - May 27, 1999 Pilcher said the data will serve as a basic reference book for Mars scientists for many years, and should provide new insights about the planet's geologic history and the ways that water has flowed across its surface during the past four billion years. David Smith, the principal investigator for MOLA, said the most curious aspect of the topographic map is the striking difference between the planet's low, smooth northern hemisphere and the heavily cratered southern hemisphere, which sits, on average, about three miles (five km) higher than the north. Mars Global Surveyor carries five science instruments designed to generate a complete global portrait of Mars and its seasonal changes during a full Martian year, the equivalent of two Earth years. www.cnn.com /TECH/space/9905/27/mars.map   (538 words)

NSSDC Master Catalog Display: Spacecraft The attached orbiter/bus and descent module had a mass of approximately 4650 kg at launch (including fuel) and was 4.1 meters high, 5.9 meters across the two solar panel wings, and had a base diameter of 2 meters. A three axis magnetometer to measure the interplanetary and martian fields was mounted on a boom extending from one of the solar panels. The Mars 3 orbiter also carried a French-built experiment which was not carried on Mars 2. nssdc.gsfc.nasa.gov /database/MasterCatalog?sc=1971-049A   (723 words)

Mars 3 Orbiter Mission Profile Mars 3 was launched towards Mars from a Tyazheliy Sputnik (71-049C) Earth orbiting platform. Meanwhile, the orbiter engine performed a burn to put the spacecraft into a long 11-day period orbit about Mars with an inclination thought to be similar to that of Mars 2 (48.9 degrees). It was announced that Mars 2 and 3 had completed their missions by 22 August 1972. library.thinkquest.org /19455/mars3_mission_profile.htm   (133 words)

CNN.com - NASA: Liquid water once on Mars - Mar. 3, 2004 While reporters pushed the scientists to come up with a "when" for the existence of water on Mars, Squyres said it was very difficult to infer an age simply by looking at pictures. From their knowledge of rocks on earth, scientists say rocks with as much salt as this Mars rock either formed in water, or had a long exposure to water after they were formed. Scientists say the case for a watery past is further strengthened by the pictures taken by the rovers' panoramic cameras and its microscopic imager. www.cnn.com /2004/TECH/space/03/02/mars.findings   (979 words)

Mars Polar Lander Timeline The lander is cruising to Mars powered by a cruise stage that provides maneuvering capability and solar power. MSOP has responsibiltiy for operating all the spacecraft in the Mars Surveyor Program, which includes the Mars Global Surveyor (MGS) orbiter, the Mars Climate Orbiter (MCO) and the Mars Polar Lander (MPL). By this time, the Mars Global Surveyor Orbiter had achieved its final mapping orbit and obtained new photographic and topographic observations of the landing site region. mars.sgi.com /msp98/lander/timeline2.html   (911 words)

Mars probe program - Wikipedia, the free encyclopedia The 1973 Mars launch window was inefficient and thus the Proton rocket could not deliver the mass to Mars, as had been possible in 1971. The descent module separated from the bus at a distance of 48,000 km from Mars. Unfortunately, much of the data were unreadable due to a flaw in a computer chip which led to degradation of the system during its journey to Mars. en.wikipedia.org /wiki/Mars_probe_program   (1520 words)

What NASA Isn't Telling You About Mars - Part 3 Incredibly, the Opportunity and Spirit rovers on Mars are now entering their third year of operation. The evidence and facts about unusual happenings and objects on Mars are right out in plain sight, if one knows what to look for. Temperature measurements didn't agree with ice formation, and seemed to indicate that some type of atmosphere must be present to explain the observations and images. www.rense.com /general69/newmar.htm   (1357 words)
