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. Launch was proposed for September 2009. By December 14, 2004, eight proposals were selected, including
Mars 2020 that were under consideration for Mars 2020. A workshop was held on 8–10 February 2017 in Pasadena, California, to discuss these sites, with the goal of narrowing down the list to three sites for further consideration. The selected sites are: In November 2018, it was announced that Jezero crater was chosen as the planned landing site for Mars 2020 rover. A key mission requirement for this rover is that it must help prepare NASA for its Mars sample-return mission (MSR) campaign, which is needed before any crewed mission takes place. Such effort would require three additional vehicles: an orbiter, a
