2001 Mars Odyssey first few minutes on the Martian surface. "Odyssey" also acts as a relay for UHF radio signals from the (MSL) rover "Curiosity". Because "Odyssey" is in a Sun-synchronous orbit, it consistently passes over "Curiosity"s location at the same two times every day, allowing for convenient scheduling of contact with Earth. 2001 Mars Odyssey 2001 Mars Odyssey is a robotic spacecraft orbiting the planet Mars. The project was developed by NASA, and contracted out to Lockheed Martin, with an expected cost for the entire mission of US$297 million.

Mars Exploration Rover one Martian year anniversary (669 sols or 687 Earth days) on November 20, 2005. "Opportunity" celebrated its anniversary on December 12, 2005. At the beginning of the mission, it was expected that the rovers would not survive much longer than 90 Martian days. The Columbia Hills were "just a dream", according to rover driver Chris Leger.
