The Mars time of noon is 12:00 which is in Earth time 12 hours and 20 minutes after midnight. For the Mars Pathfinder, Mars Exploration Rover (MER), Phoenix, and Mars Science Laboratory missions, the operations teams have worked on "Mars time", with a work schedule synchronized to the local time at the landing site on Mars, rather than the ...
A Martian year is approximately 668.6 sols, equivalent to approximately 687 Earth days [1] or 1.88 Earth years. The sol was adopted in 1976 during the Viking Lander missions and is a measure of time mainly used by NASA when, for example, scheduling the use of a Mars rover .
The basic time periods from which the calendar is constructed are the Martian solar day (sometimes called a sol) and the Martian vernal equinox year.The sol is 39 minutes 35.244 seconds longer than the Terrestrial solar day, and the Martian vernal equinox year is 668.5907 sols in length (which corresponds to 686.9711 days on Earth).
Curiosity rover on Mars (5 August 2015) The Mars Science Laboratory and its rover, Curiosity, were launched from Earth on 26 November 2011. As of February 7, 2025, Curiosity has been on the planet Mars for 4446 sols (4568 total days; 12 years, 185 days) since landing on 6 August 2012. (See Current status.)
While Spirit became immobile in 2009, and ceased communications in 2010, Opportunity exceeded its planned 90 sol (Martian days) duration of activity by 14 years 46 days (in Earth time). Opportunity continued to move, gather scientific observations, and report back to Earth until 2018. What follows is a summary of events during its continuing ...
