NASA’s Perseverance rover has now serene a dozen Martian rocks.
The automobile-sized Perseverance drilled out and sealed up its 12th rock sample on Wednesday (Aug. 3), mission crew contributors presented through Twitter (opens in fresh tab) this day (Aug. 5) — its fourth such operation in lower than a month.
In February 2021, Perseverance landed with NASA’s exiguous Ingenuity helicopter on the floor of the 28-mile-large (45 kilometers) Jezero Crater, which harbored a extensive lake and a river delta billions of years ago. The six-wheeled rover is trying to gain indicators of outmoded Mars life and bagging up dozens of samples for future return to Earth, among other responsibilities.

The well-known eight rock samples that Perseverance serene — from September 2021 to March of this twelve months — were volcanic in initiating save, in accordance with the mission crew’s sample log (opens in fresh tab). However the final four, which occupy been gathered between July 7 and Wednesday, all attain from sedimentary rocks.
As that commerce suggests, Perseverance is now exploring a remnant of the delta, inspecting layered rock formations that constructed up over time as silt fell out of Jezero’s outmoded river. Such deposits are extra doubtless than volcanic ones to harbor natural compounds and other that you may perchance also factor in indicators of Mars life, if it ever existed, Perseverance crew contributors occupy stated. So it is now now not frightful that the sample-gathering high-tail has now picked up.
Perseverance carries a total of 43 sample tubes, 38 of that would also also be stuffed with Martian rock and dust. The opposite five are “peep tubes,” which will succor the mission crew settle which materials, if any, in serene samples would be contaminants from Earth.
Perseverance has now sealed up 15 of these 43 tubes. Twelve own rock cores, one holds Martian air, and the opposite two are peep tubes. (The “atmospheric sample” used to be sealed within the aftermath of Perseverance’s abortive first rock capture, an August 2021 strive that failed when the drilled cloth crumbled to bits.)
These tubes will be dropped at Earth by a joint NASA-European Dwelling Company (ESA) campaign, per chance as early as 2033. The structure of that campaign changed now now not too long ago; NASA and ESA determined to save away with an ESA-equipped “acquire rover” and rely as every other on Perseverance and, if wished, two Ingenuity-cherish helicopters to divulge the sample tubes to the NASA rocket that will delivery them off the Martian surface.
