Mars Odyssey arrives at the red planet

2001 Mars OdysseyNASA’s 2001 Mars Odyssey probe reaches Mars and settles into an orbit which will gradually be corrected by aerobraking (using the friction of the planet’s atmosphere to slow the vehicle down). Unlike the Mars Surveyor mission, Odyssey does not contain a landing probe, but will instead look at the planet from orbit. Another unique feature of Odyssey’s mission plan is the fact that it won’t be shut down when its scientific investigation has come to an end; it will be left in Mars orbit to serve as a communications relay satellite for future missions.
