The design of Mars lander cameras for Mars Pathfinder, Mars Surveyor '98 and Mars Surveyor '01
The Mars Pathfinder, Mars Surveyor ’98, and Mars Surveyor ’01 lander designs all utilize charged coupled device (CCD)-based cameras to conduct scientific investigations, assist with navigation of surface rovers and/or confirm sample acquisition and delivery by robotic arms (RAs). The extreme temperature and pressure environment of the Martian surface, the vibration and shock experienced during ...
متن کاملMartian clouds observed by Mars Global Surveyor Mars Orbiter Camera
[1] We have made daily global maps that cover both polar and equatorial regions of Mars for Ls 135 –360 and 0 –111 using the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) red and blue wide-angle swaths taken from May 1999 to January 2001. We study the seasonal distribution of condensate clouds and dust clouds during roughly 1 Martian year using these daily global maps. We present the dev...
متن کاملOverview of the Mars Global Surveyor mission
The Mars Global Surveyor spacecraft was placed into Mars orbit on September 11, 1997, and by March 9, 1999, had slowly circularized through aerobraking to a Sunsynchronous, near-polar orbit with an average altitude of 378 km. The science payload includes the Mars Orbiter Camera, Mars Orbiter Laser Altimeter, Thermal Emission Spectrometer, Ultrastable Oscillator (for Radio Science xperiments), a...
متن کاملMars global surveyor mission: overview and status.
The Mars Global Surveyor (MGS) spacecraft achieved a 45-hour elliptical orbit at Mars on 11 September 1997 after an 11-month cruise from Earth. The mission is acquiring high-quality global observations of the martian surface and atmosphere and of its magnetic and gravitational fields. These observations will continue for one martian year.
متن کاملThe gravity field of Mars: results from Mars Global Surveyor.
Observations of the gravity field of Mars reveal a planet that has responded differently in its northern and southern hemispheres to major impacts and volcanic processes. The rough, elevated southern hemisphere has a relatively featureless gravitational signature indicating a state of near-isostatic compensation, whereas the smooth, low northern plains display a wider range of gravitational ano...
