One of many fundamental jobs for the Perseverance Mars rover previous few weeks has been collecting carefully selected samples of Mars rock and soil. These samples have been positioned and sealed in particular pattern tubes and left in well-identified places so {that a} future sample return mission can accumulate them and convey the Martian samples again to Earth.
Perseverance has now dropped 10 pattern tubes and to have fun, it took a few selfies with a number of of the pattern tubes seen within the designated ‘pattern depot’ it’s creating inside an space of Jezero Crater. The realm of the depot is nicknamed “Three Forks.”
The selfie was taken by the rover utilizing its WATSON (Vast Angle Topographic Sensor for Operations and eNgineering) digital camera on the tip of the robotic arm on Jan. 20, 2023, the 682nd Martian day, or sol, of the mission.
The selfies are composed of 56 particular person WATSON photos that had been stitched collectively as soon as they had been despatched again to Earth. Seen on the bottom proper subsequent to the rover on this picture is the ninth tube that was dropped by Perseverance. Different pattern tubes are seen as properly.
On this animated GIF, the rover seems down on the pattern tube after which again on the digital camera, like a proud mum or dad.
NASA says the depot marks a vital milestone within the Mars Pattern Return marketing campaign, which is being collectively established by NASA and ESA, and plans and details of the mission are currently in development. Perseverance is the primary mission to display this capacity on Mars, and it might doubtlessly pave the best way for future missions that would accumulate the samples and return them to Earth for intensive laboratory evaluation. This primary depot will function a backup if Perseverance can’t ship its samples to a future robotic lander.
The depot location has been well-documented by each native landmarks and exact coordinates from orbital measurements so {that a} future mission might land close by and journey to gather the pattern tubes.
The sampling equipment is kind of spectacular, and the stomach of the rover homes all of the tools and provides wanted to gather samples. It incorporates a rotating drill carousel, which is a wheel that incorporates totally different sorts of drill bits. Subsequent to which might be the tubes—there was 43 pattern tubes complete firstly of the mission.
Whereas the rover’s massive arm reaches out and drills rock, the rover stomach additionally incorporates a small robotic arm that works as a “lab assistant” to the large arm. The small arm picks up and strikes new pattern tubes to the drill, and transfers crammed pattern containers into an area the place they’re sealed and saved.
After a pattern is collected, the pattern tube is transferred again to the rover’s stomach. There, it’s handed off to the small inside robotic arm and moved to inspection and sealing stations. As soon as the tube is hermetically sealed, nothing can enter or go away it. The tubes are saved within the rover stomach till the staff decides on the time and place to drop the samples off on the floor.
This pattern return capacity is a part of the aims for Perseverance’s mission, which incorporates astrobiology and looking for indicators of historic microbial life. The rover will characterize the planet’s geology and previous local weather, hopefully paving the best way for human exploration of the Pink Planet.
