NASA’s Mars rover on a roll as it collects second rock sample in a week

NASA’s Perseverance rover has extracted and securely stored its second sample of martian rock just days after its first successful collection.

The space agency’s Jet Propulsion Laboratory (JPL), which is overseeing the Mars mission, shared the news in a tweet on Wednesday, September 8.

“Two for two: I have successfully processed and stored my second sample of Mars, thus bringing my total to two Martian rock cores in one week,”  reads a post on the Perseverance Twitter page that also features images showing the drilled rock and collection tube with the material inside.

The achievement suggests JPL has finally nailed the rover’s sample-collection process following a failed effort in August when the loose consistency of the gathered material caused it to slip out of the collection tube.

Afterwards, the JPL team directed Perseverance to another rock with a more stable structure. Both stored samples have come from this rock, with the rover drilling out pieces about the size of a pencil before storing them in titanium tubes.

Perseverance will continue to drill material from different rocks during its exploration of Jezero Crater, a dried-up lake bed. While the rover will use its suite of onboard instruments to examine the samples, a later mission will aim to transport the haul to Earth so scientists can use more powerful analytical tools to hopefully discover more about the red planet and its history.

“Using the most sophisticated science instruments on Earth, we expect jaw-dropping discoveries across a broad set of science areas, including exploration into the question of whether life once existed on Mars,” said Thomas Zurbuchen, NASA’s associate administrator for science.

Perseverance reached Mars in February 2021 and since then has been exploring the surface of the planet, sending back fresh imagery — and audio — as well as preparing for its sample collections.

Unlike NASA’s previous rover missions, Perseverance brought with it a traveling companion in the form of a drone-like flying machine called Ingenuity, which in April became the first aircraft to perform powered, controlled flight on another planet.

Ingenuity was sent as a test device to see if such a machine could help future rovers plan their routes more efficiently and safely. But the aircraft’s numerous test flights have been going so well that Ingenuity itself has been able to help Perseverance find its way around the surface of Mars.

NASA is looking for volunteers for yearlong simulated Mars mission
The CHAPEA mission 1 crew (from left: Nathan Jones, Ross Brockwell, Kelly Haston, Anca Selariu) exit a prototype of a pressurized rover and make their way to the CHAPEA facility ahead of their entry into the habitat on June 25, 2023.

If you've ever wanted to visit Mars, then NASA has an offer for you. Though the agency isn't sending humans to the red planet quite yet, it is preparing for a future crewed Mars mission by creating a simulated mission here on Earth -- and it's looking for volunteers.

Simulated missions look at people's psychological and health responses to conditions similar to what astronauts would experience on a deep space mission. In the case of the Mars mission, called Crew Health and Performance Exploration Analog or CHAPEA, the aim is to simulate a Martian environment using a 3D-printed habitat and a set of Mars-related tasks that crew members must perform.

NASA has collected a whopping 121 grams of sample from asteroid Bennu
A view of eight sample trays containing the final material from asteroid Bennu. The dust and rocks were poured into the trays from the top plate of the Touch-and-Go Sample Acquisition Mechanism (TAGSAM) head. 51.2 grams were collected from this pour, bringing the final mass of asteroid sample to 121.6 grams.

When the OSIRIS-REx dropped a capsule in the Utah desert last year, it made headlines around the globe for returning NASA's first sample of an asteroid to Earth. Scientists were eager to get their hands on the sample of asteroid Bennu to learn about the early formation of the solar system, but actually getting at the sample proved to be rather trickier than imagined.

Scientists were able to extract 70 grams of material from the sample canister relatively easily, making it by far the largest asteroid sample ever brought to Earth, but two troublesome fasteners made it difficult to extract the rest of the sample. The team knew it had plenty more sample inside, but it had to be patient as special new tools were constructed that could undo the fasteners without losing a single gram of the precious sample.
