Perseverance has Collected its First Sample of Mars and Prepared it for Return to Earth… Eventually

It’s another first for NASA.

In early September, the Perseverance rover successfully used its robotic arm and drill to drill into a rock and extract a sample. It extracted a rock core about 6 cm (2 in) long and placed it inside a sealed tube. This is the first time a robotic spacecraft has collected a sample from another planet destined for a return to Earth on a separate spacecraft.

Now we wait for the eventual return of the sample to Earth.

Perseverance Drills Another Hole, and This Time the Sample is Intact

When it landed on Mars in February of 2021, the Perseverance rover joined a small armada of robotic explorers working hard to characterize Mars’ environment and atmosphere and determine if it ever supported life. But unlike its predecessors, one of the key objectives of the rover is to obtain samples of Martian soil and rock, which it will leave in a cache for later retrieval by a joint NASA-ESA mission.

This will be the first sample return from Mars, and the analysis of these samples will provide new insight into the geological and environmental evolution of Mars. The first attempt to obtain a sample didn’t go so well, with the sample crumbling before it was placed in the cache. Undeterred, the science team moved onto the next site and prepared to try again. A few days ago, NASA confirmed that the rover succeeded in its second attempt and has the pictures to prove it!

Just A Couple Of Weeks From Now, OSIRIS-REx Will Grab A Sample From Bennu

NASA is about to achieve another first for their organization. In about three weeks time, on October 20th, the OSIRIS-REx spacecraft will descend to Bennu’s surface, briefly touch down, and collect a sample from the asteroid. The spacecraft will collect a minimum of 60 grams (2 oz.) of material for return to Earth.
