Mars Phoenix Lander Post Landing Briefing http://www.space-multimedia.nl.eu.org/index.php?option=com_content&task=view&id= 3703&Itemid=2 Mars Phoenix Lander Briefing - First Downlink of Data http://www.space-multimedia.nl.eu.org/index.php?option=com_content&task=view&id= 3702&Itemid=2 Mars Phoenix Lander Landing Coverage http://www.space-multimedia.nl.eu.org/index.php?option=com_content&task=view&id= 3701&Itemid=2 The neat NASA animations provided to the media shows how rockets slowled the ship down prior to landing. Out of curiosity, doesn't that contaminate the soil all around the landing side and kill off all life with the fire/heat of the rockets ? How do they mitigate this problem ?

The low Martian gravity means the terminal velocity isn't all that great and the legs take up the impact. A future mission will have the lander descend on a hovering platform, lowered by a winch. The platform will translate a distance away before setting down/impacting. --Damon >A future mission will have the lander descend on a hovering platform, >lowered by a winch.

But isn't that mission the big rover (humvee version of MER)? So contamination isn't much of an issue since it can just drive away. Landing on a boulder is that mission's concern.
