Timeline of Mars Science Laboratory November 27, 2013, an overview (titled, "The World of Mars") of current and proposed Mars exploration by John Grotzinger, chief scientist of the "Curiosity" rover mission, was published in the New York Times. On December 9, 2013, NASA reported that the planet Mars had a large freshwater lake (which could have been a hospitable environment for microbial life) based on evidence from the "Curiosity" rover studying Aeolis Palus near Mount Sharp in Gale Crater. On December 9, 2013, NASA researchers described, in a series of six articles in the journal Science, many new discoveries from the "Curiosity" rover. Possible organics
Mars Surveyor 2001 Lander is identical to that of the Mars Polar Lander, which had been intended to be the first of a series of low-cost "Mars Surveyor" landers sent to Mars. Prior to mission cancellation, cost overruns and technical problems caused the Lander design to be rescoped, and the planned large Athena rover was replaced by a small rover duplicating the "Sojourner" which was a part of the Mars Pathfinder mission. (The Athena did later make it to Mars, however, with two such rovers making up the Mars Exploration Rover Mission of 2004. The second of these, MER-B "Opportunity", landed at Mars Surveyor
