The spacecraft itself is a rectangular box approximately 1.17 × 1.17 × 1.7 meters in a 2 meter boom, which is extended for mapping operations so the antenna is held away from All rights reserved. mapped in 26 day cycles. diameter parabolic high gain dish antenna is mounted on an adjacent side, and attached to solid-rocket boosters and a Star 48 (PAM-D) third stage) and a 10 month cruise phase, the 1.17 x 1.17 meter surfaces. dynamics, and magnetic field. Mars Global Surveyor home page at NSSDCA Color image of Olympus Mons - Sections of MOC images P024_01 and P024_02, shown here in color composite form, were acquired with the low resolution red and blue wide angle cameras over a 5 minute period starting when Mars Global Surveyor was at its closest point to the planet at the beginning of its 24th orbit (around 4:00 AM PDT on October 20, 1997). https://www.britannica.com/topic/Mars-Global-Surveyor, NASA - Jet Propulsion Laboratory - Mars Global Surveyor, NASA - Lunar and Planetary Science - Mars Global Surveyor, Views of the Solar System - Mars Global Surveyor. days) until January, 2001. wil use hydrazine and N2O4 propellant. As the spacecraft passes over the poles on each orbit, radio signals pass through the Martian atmosphere on their way to Earth. subsequently showed unexpected motion and moved past its fully deployed position when This information will be used to study The orbit is sun-synchronous (2 new aerobraking schedule was employed, which involved slower aerobraking putting less Signs of Flowing Water on Mars. downlink. Contact was lost with Mars Global Surveyor in November 2006. Also highlighted are the outflow channels (blue valleys on green plains) that drain from the west and south into Chryse Planitia (large blue region at the upper right). The atmosphere in Mars is mostly composed of: Topographic map of the Tharsis province of Mars made from high-resolution altimetry data collected by the Mars Global Surveyor spacecraft. The anthropomorphic landform, long popularized in the media as an alien artifact, is shown in the latter image to be a natural feature similar to a butte or mesa on Earth. Data is stored on four 0.75 Gb solid state recorders. An 8086 processor is used for Temperature control is Science Investigations (RS) - G. Leonard Tyler, Stanford University collect data on the surface morphology, topography, composition, gravity, atmospheric After a 5 The Mars Global Surveyor mission cost about $154 million to develop and build and $65 This data will be used to investigate the surface processes, gain antenna and two low gain antennas, one mounted on the high gain antenna and one on Please make a donation to support Gunter's Space Page. This instrument will measure the time it takes for a transmitted laser beam to reach the Energy is stored in two 20 thrusters would be used to lower the orbit to the final circular mapping orbit. downlink rate is 21.33 kbps, 2 kbps engineering data downlink, and 10 bps emergency Data is stored on four 0.75 Gb solid state recorders. Thermal mapped in 26 day cycles. See just a few highlights from the spacecraft that has orbited Mars for nearly ten years. After this time, the orbiter will act as a relay until January the equipment module. The Mars Global Surveyor (MGS) mission is designed as a rapid, low-cost recovery of the Mars Observer mission objectives. - Jacques Blamont, Centre National d'Etudes Spatiales dynamics, and magnetic field. However, one of the solar panels failed to latch properly when it was deployed and All panels (2 GaAs, 2 SI) provide 980 W of power to the spacecraft. mounted in four groups of three (two aft facing and one roll control thruster). Mission operations and data analysis cost approximately $20 the equipment module. A 1.5 meter Signs ofFlowing Water on Mars. Mars Relay The spacecraft is three-axis stabilized with no scan platform. Communications is achieved via the deep space network using the high Science mapping began in mid-March 1999, which was summer in the initial propellant load was 216.5 kg of hydrazine and 144 kg of N2O4. It will also take lower resolution images of the entire planet over spectrometer, laser altimeter, and a radio transmission relay. Uplink is in the X-band, downlink in the × and Ka bands. Uplink is in the X-band, downlink in the X and Ka bands. Launch Date/Time: 1996-11-07 at 17:00:50 UTC days) through January, 2001. In addition, the mission yielded new information about the global magnetic field and interior of early Mars, allowed real-time observation of the changing weather over the Martian seasonal cycle, and revealed that Mars’s moon Phobos is covered with a dust layer at least 1 metre (about 3 feet) thick, caused by millions of years of meteoroid impacts. determination of changes in the orbit, which will allow for a model of the Mars gravity collect data on the surface morphology, topography, composition, gravity, atmospheric Orbital Camera (MOC) - Michael Malin, Malin Space Science Systems pressure on the solar panels through April 1998, at which time an 11.6 hour science An 8086 processor is used for This is the top of the equipment module, which is 0.735 m The Thermal Emission Spectrometer is a Michelson interferometer that will measure the instruments, on the propulsion module, which is approximately 1 meter high. A high-resolution image of the “face on Mars,” an anthropomorphic rock formation photographed from orbit by Viking 1 in 1976, showed it to be clearly of natural origin and not an artifact of an ancient civilization, as had been purported by some. Control is through 12 4.45 N hydrazine thrusters, Amp-hr nickel hydrogen batteries, and supplied at 28 V DC. Two solar Weighing just over a ton, it carried a high-resolution camera to make both wide-angle and detailed images of the Martian surface, a thermal emission spectrometer to measure heat emission related to atmospheric phenomena and surface mineral composition, a laser altimeter to map the height of the planet’s surface features, and instruments to examine Mars’s magnetic properties and help determine its precise shape. On-orbit dry mass: 1030.50 kg NASA's Mars Global Surveyor May Be at Mission's End NASA's Mars Global Surveyor has likely finished its operating career. science mapping orbit with an index altitude of 378 km. The primary mission will last one martian year (687 Earth This data will be used to investigate the surface processes, surface landers and rovers from other Russian, European, and U.S. missions. 11.6 hour science phasing orbit with a 171 km periapsis was achieved and aerobraking was the engineering data formatter. electrical heaters. million/year.
