NASA’s Perseverance Mars rover has dropped its fourth rock pattern tube at a location in Jezero Crater, that means its first backup pattern depot is now 40% full.
Perseverance, which landed on the Crimson Planet in February 2021, will stash 10 samples total on the location known as Three Forks, which is located in an historic river delta on the ground of the 28-mile-wide (45 kilometers) Jezero Crater.
“Pattern Depot: 40% full!,” the rover staff celebrated by way of NASA’s Perseverance Twitter account (opens in new tab)on Wednesday (Jan. 4). “One other profitable tube drop provides to my rising assortment right here on the ‘Three Forks’ location. 4 of the ten tubes I am leaving right here as a backup set are down.”
Perseverance has delivered to Mars 43 6-inch-long (15.2 centimeters) titanium tubes, 38 of which might be full of samples of Martian dust, grime and rock. The remaining 5 tubes might be used to measure the cleanliness of the sampling system, NASA stated in a statement (opens in new tab).

NASA scientists are particularly in search of samples from places which will have harbored microbial life billions of years in the past, hoping traces of those microbes may nonetheless be detectable within the materials. NASA and the European House Company will work collectively to collect Perserverance’s samples and deliver them to Earth for detailed examine, maybe as early as 2033.
The stash at Three Forks is meant as a backup. Perseverance collects two samples from every of its goal rocks, maintaining one inside its stomach. The first objective is for the rover itself to ship the samples to an incoming NASA lander, which can carry a rocket to blast the samples off the Martian floor. However in case Perseverance, which on the time of the pattern return mission’s arrival could possibly be over 10 years previous, will get caught someplace, a pair of helicopters, which can arrive with the lander, will acquire the backup samples and take them to the return car, according to NASA (opens in new tab).
Perseverance dropped its first sample at Three Forks on Dec. 21. The entire operation was far more technically demanding than it might need checked out first look. For instance, the bottom management staff needed to be sure that the pattern tubes had been within the right place and had not rolled beneath the rover’s wheels. Simply retrieving the pattern from contained in the rover took about one hour per pattern, NASA stated within the assertion.
Based on an earlier Perseverance Twitter thread (opens in new tab), scientists aren’t fearful that infamous Martian dust storms may fully bury the dear tubes in grime over the subsequent decade. And in case a lot dust collects on the tubes that they’re not seen, Perseverance is making a cautious document of their actual place in order that “going again to them once more later shouldn’t be a difficulty,” the rover staff said in a tweet (opens in new tab) final month.
