The Perseverance rover landed in Mars’ Jezero Crater largely due to in depth proof that the crater as soon as hosted a lake, that means the presence of liquid water which may as soon as have hosted Martian life. And the touchdown was a hit, putting the rover on the fringe of a construction that seemed to be a river delta the place the close by highlands drained into the crater.

However a abstract of the primary 12 months of information from the rover, printed in three totally different papers being launched at the moment, means that Perseverance has but to stumble throughout any proof of a watery paradise. As a substitute, all indications are that water publicity within the areas it explored was restricted, and the waters had been prone to be close to freezing. Whereas this does not rule out that it’ll discover lake deposits later, the setting may not have been as welcoming for all times as “a lake in a crater” might need advised.

Placing all of it collectively

Perseverance may be thought-about a platform for a big suite of devices that present an image of what the rover is taking a look at. Even its “eyes,” a pair of cameras on its mast, can create stereo photos with 3D data, and provide data on what wavelengths are current within the photos. It additionally has devices that may be held as much as rocks to find out their content material and construction; sample-handling {hardware} can carry out a chemical evaluation of supplies taken from rocks.
