A Martian "sol" lasts about 40 minutes longer than an Earth day, and a Martian year lasts nearly two Earth years. Opportunity's Sol 1 was landing day, Jan. 25, 2004 (that's in Universal Time; it was Jan. 24 in California). The prime mission was planned to last 90 sols. NASA did not expect the rover to survive through a Martian winter. Sol 5,000 will begin early Friday, Universal Time, with the 4,999th dawn a few hours later. Opportunity has worked actively right through the lowest-energy months of its eighth Martian winter.

With the first flight of Ingenuity a success, we’re looking toward our second taking place on April 22, which is the 18th of the 30 sols (Martian days) of our flight test window.
For this second flight test at “Wright Brothers Field,” we are targeting a takeoff time for 5:30 a.m. EDT (2:30 a.m. PDT), or 12:30 p.m. Local Mean Solar Time.

NASA’s Ingenuity Mars Helicopter continues to set records, flying faster and farther on Sunday, April 25, 2021 than in any tests it went through on Earth. The helicopter took off at 4:31 a.m. EDT (1:31 a.m. PDT), or 12:33 p.m. local Mars time, rising 16 feet (5 meters) – the same altitude as its second flight.
