The Mars rover Perseverance has pebbles trapped in its drill. NASA has a system to fix it.
NASA’s Perseverance rover will dump its latest Mars sample to unclog pebbles from its drill.
Perseverance mission administrators manufactured the unforeseen announcement that they experienced to dump out Percy’s most current sample by way of a blog write-up on Friday (Jan. 14). The group even shared in the post that they in no way believed they would have to do that as one particular of Perseverance’s primary targets is to pick up Mars samples for foreseeable future assessment.
“I by no means imagined we would accomplish [this maneuver] – ever,” wrote Jennifer Trosper, task supervisor at NASA’s Jet Propulsion Laboratory, in the blog. “Merely set, we are returning the remaining contents of Sample Tube 261, our most up-to-date cored-rock sample, again to its planet of origin.”

The vehicle-sized rover described the trapped particles publicly throughout its sixth rock core seizure on Jan. 7, by means of the mission’s Twitter account and a earlier blog site publish. Engineers have continued to do the job on the challenge to apparent the difficulty without the need of producing any hurt to the craft. This take care of will possible call for that Percy sit in position for an additional week or so.
Trosper outlined the measures JPL has taken so much to determine out a option. Perseverance took pictures of the floor below on Jan. 12 so “we would have a great idea what rocks and pebbles already exist down there,” she claimed. There has also been some “terrestrial experimentation,” however Trosper did not elaborate on what exactly this entails.
Pre-start rover screening on Earth uncovered that evacuating the drill’s assortment tube is reasonably straightforward to do, she described, though this hasn’t been analyzed nevertheless on windy, dusty Mars the place the gravity is a quarter that of our possess planet’s.
“We sent commands up yesterday, and afterwards on currently the rover’s robotic arm will simply point the open up stop of the sample tube toward the area of Mars and let gravity do the relaxation,” Trosper mentioned, meaning the procedure was most likely completed more than this earlier weekend. Results are expected to be documented on Tuesday (Jan. 18).
The instructions will ask the rover to do rotation tests of its little bit carousel to assess pebble motion, and much more info will arrive from new shots taken beneath Perseverance to see if far more “pebbles come about to pop no cost,” she reported.
The workforce is not guaranteed how a lot of the cored rock is still in the tube, but if the evacuation goes properly they may well endeavor to redo the coring technique. Perseverance is caching samples like this a person for a prepared sample-return mission to choose up.
