Timeline of Mars Science Laboratory of the glitch in Side-B is determined and remedied. Timeline of Mars Science Laboratory Timeline of Mars Science Laboratory is a timeline of the Mars Science Laboratory mission and its rover, "Curiosity". As of 23, 2019, "Curiosity" has been on the planet Mars for sols ( total days; ) since landing on August 6, 2012. "(See Current status.)" In April 2004, the United States National Aeronautics and Space Administration (NASA) called for scientific experiments and instruments proposals for the Mars Science Laboratory and rover mission.

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.
