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. ]FIG] [5] [CITE@en[Mention Zone names with two slashes]] ([[eggert]]著, [TIME[2018-04-06 09:42:08 +09:00]]) [6] [CITE[Kyoto University Research Information Repository: 火星世界の時制 (時と曆の特輯)]] ([TIME[2018-03-23 14:45:26 +09:00]]) [7] [CITE@ja[さっき妻が電話で「夫が火星時間勤務になっちゃって…毎日40分ずつずれるそうで…前代未聞の時差ボケですよ…」と話していて相手が困惑していた - Togetter]], [TIME[2021-02-18T12:20:41.000Z]] [FIG(quote)[ [FIGCAPTION[ [9] [CITE@en[We're Getting Ready for Ingenuity’s Second Flight - NASA Mars]] ([[mars.nasa.gov]], [TIME[2021-04-26T06:12:22.000Z]]) ]FIGCAPTION] > With the first flight of Ingenuity a success, we’re looking toward our second taking place on April 22, which is the 18[SUP[th]] 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. ]FIG] [10] [CITE[- 9Page41.pdf]], [TIME[2021-04-21T19:29:09.000Z]], [TIME[2021-04-26T06:14:16.972Z]] [FIG(quote)[ [FIGCAPTION[ [11] [CITE@en[NASA's Ingenuity Mars Helicopter Flies Faster, Farther on Third Flight – NASA’s Mars Exploration Program]] ([[mars.nasa.gov]], [TIME[2021-04-26T06:15:35.000Z]]) ]FIGCAPTION] > 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.
