Final fate??

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

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

Infobox says "Apoapsis 17,836 km (11,083 mi)" which seems out of date.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

[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?

"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)
