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
Sol (day on Mars) Mars Sol Date is defined mathematically as MSD = (Julian Date using International Atomic Time - 2451549.5 + "k")/1.02749125 + 44796.0, where "k" is a small correction of approximately 0.00014 d (or 12 s) due to uncertainty in the exact geographical position of the prime meridian at Airy-0 crater. The word "yestersol" was coined by the NASA Mars operations team early during the MER mission to refer to the previous sol (the Mars version of "yesterday"), and came into fairly wide use within that organization during the Mars Exploration Rover Mission of 2003. It was eventually picked up and used
