Comment[edit]

cProto a technique in which the spacecraft is pitched to slow the apparent speed of the ground below. [1]

Final fate??[edit]

Does anyone know what has become of the physical spacecraft, has it de-orbited, will it de-orbit if so when? anyone have a clue? —Preceding unsigned comment added by 137.99.173.204 (talk) 21:34, 6 December 2009 (UTC)

Main article suggests it is still in near polar orbit. If the infobox "Periapsis = 171.4 km (107 mi)" is true it is well above aerobreaking heights and the orbit should last for many years. Rod57 (talk) 12:17, 15 December 2010 (UTC)

Current status[edit]

Article says it was last heard of in 'safe mode' in 2006. Anyone know what it will do when the battery fails ? When is the battery likely to fail ?

Can it maintain attitude (to keep at least one solar panel facing the sun?)? When might the attitude control fail (propellants exhausted ?) ? How much propellant remained when contact was lost ? Rod57 (talk) 12:17, 15 December 2010 (UTC)

orbital elements in infobox[edit]

Infobox says "Apoapsis 17,836 km (11,083 mi)" which seems out of date. Should that be the figure when science operations started, or the last known ? Rod57 (talk) 12:23, 15 December 2010 (UTC)

Longevity record[edit]

[2] suggests that until Dec 2010 MGS held the record for longest period of operation in Mars orbit. Rod57 (talk) 12:36, 15 December 2010 (UTC)

Is there anything like List of craft in Martian orbit ? Closest I can find is Mars#Current_missions and Exploration_of_Mars#Timeline of Mars exploration. Rod57 (talk) 12:45, 15 December 2010 (UTC)

10-year absence?[edit]

"It began the United States's return to Mars after a 10-year absence." Is this right? I think the gap was longer than that, with the previous successful mission being Viking 1 which was terminated on November 11, 1982. — Preceding unsigned comment added by 174.62.66.19 (talk) 11:04, 23 November 2011 (UTC)
