The realm must be not solely flat as in missing hills, but additionally missing in massive boulders or sand dunes, each of which might trigger issues for a touchdown car.

The workforce is ready to get an concept of potential areas by taking a look at information taken by Mars orbiters, which might take photographs of the planet’s floor at impressively excessive resolutions given how far-off they’re.

“We had been eyeing these areas since earlier than Perseverance’s touchdown, however imagery from orbit can solely inform you a lot,” stated JPL’s Mars Pattern Return Methods Engineering & Integration supervisor, Al Chen. “Now now we have some up-close-and-personal photographs of the touchdown strip that point out we have been proper on the cash. The touchdown strip will greater than doubtless make our shortlist of potential touchdown and caching websites for MSR.”
