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 sample-return mission complexity and technical problems. One mission concept (provisionally named simply Mars Sample-Return) was originally considered by NASA's Mars Exploration Program to return samples by 2008, but was cancelled following a review of the program. A NASA-ESA concept mission was aborted in 2012. The United States' Mars Exploration Program, formed after "Mars Observer" failure in September 1992, supported a Mars sample-return. One example of a mission architecture was the "Groundbreaking Mars Sample-Return" by MacPhereson in the early 2000s. In early 2011, the National Research Council's Planetary Science Decadal Survey, which laid out mission planning priorities for the period 2013–2022 at the
