Curiosity (rover) conditions favorable for microbial life, including investigation of the role of water; and planetary habitability studies in preparation for human exploration. In December 2012, "Curiosity" two-year mission was extended indefinitely. On August 5, 2017, NASA celebrated the fifth anniversary of the "Curiosity" rover landing and related exploratory accomplishments on the planet Mars. The rover is still operational, and as of , "Curiosity" has been on Mars for sols ( total days) since landing on August 6, 2012. "(See current status.)"

Timeline of Mars Science Laboratory and natural gas on Earth. NASA stated that these findings are not evidence that life existed on the planet, but that the organic compounds needed to sustain microscopic life were present, and that there may be deeper sources of organic compounds on the planet. Since September 15, 2018, a glitch in "Curiosity"'s active computer (Side-B) has prevented "Curiosity" from storing science and key engineering data. On October 3, 2018, the JPL began operating "Curiosity" on its backup computer (Side-A). "Curiosity" will store science and engineering data normally using its Side-A computer until the cause of the glitch in Side-B is
