Perseverance Team Works on Jet-Lag Inducing ‘Mars Time’ For The Mission

NASA simply landed a brand new rover on Mars, the fruits of a 300-million-mile journey that despatched the robotic into an historical lake mattress. 

But the touchdown is just the start of the Perseverance rover’s mission. It’s set to discover Mars’ Jezero Crater for the following two years.


It will seek for indicators of historical microbial life that might have gotten trapped in sediment from the river that flowed into the lake.

Perseverance goals to gather about 40 samples of Martian rock and soil, which it should save so {that a} future NASA mission can carry them again to Earth.

At NASA, the workforce of scientists and engineers behind the Perseverance floor operations should work across the robotic’s schedule.

That means about 350 folks shall be retaining “Mars time” for the following three months – shifting their workdays 40 minutes later daily.

“The team is going to get used to getting up later and then working a little bit into the night. That’s not bad, to be on a different shift, but the problem with Mars time is that the Mars days are 40 minutes longer than the Earth days,” Jennifer Trosper, who has labored on all 5 of NASA’s Mars rovers and serves as deputy challenge supervisor for this one, mentioned in a briefing earlier than the touchdown.

The workforce normally begins work throughout the Martian afternoon, as a result of that is when the rover’s knowledge dump reaches Earth.


They work for 12 to 14 hours to arrange an add to ship again to the rover. The first shift on this cycle started at round 2 pm, Trosper mentioned, then it’s shifting 40 minutes later daily.

After 37 days – a full “cycle” – the shifts are again the place they began.

“The reason we do Mars time is because it is the most efficient way to have the rover make progress on a day-to-day basis. And that’s really important early in the mission to get it kind of unbuckled and ready to go,” Trosper mentioned.

The first duties the workforce will do with the rover on this unusual schedule contain checking all its techniques, science devices, and {hardware}.

Then it has to drive to a subject and launch the tiny helicopter it carried to Mars. The drone will conduct some take a look at flights, and after that, Perseverance can start its sample-collecting work.

But the continuously altering work hours should not simple for people, so NASA solely asks folks to do this for 3 months.

“The first cycle everybody’s excited: ‘This is cool. I’m on Mars time,'” Trosper mentioned. “By the next cycle, people start to get a little bit tired. And by the third, by the time we finish Mars time, they are well ready to be finished with Mars time. It’s hard on your body. It’s like being jet-lagged.”


Ahead of Perseverance’s touchdown, she added, she lastly purchased an eye fixed masks to assist her sleep by daylight hours.

“It took me five missions to figure this out,” Trosper mentioned. “So I’m ready. I have my earplugs, and we’ll be on Mars time.”

The wonky schedule is particularly sophisticated this yr, for the reason that pandemic means so many workforce members are working from dwelling. Taking 4 am convention calls is likely to be disruptive to sleeping relations or roommates.

So NASA has arrange some socially distanced on-site locations for workforce members to return in in the event that they wish to.

Trosper mentioned “a couple dozen people” plan to benefit from this selection throughout the subsequent three months. That manner, she mentioned, “they can not interfere with their family’s life, which is not on Mars time.”
