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 general on the location known as Three Forks, which is located in an historical river delta on the ground of the 28-mile-wide (45 kilometers) Jezero Crater.Â
“Pattern Depot: 40% full!,” the rover workforce 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 will likely be stuffed with samples of Martian dust, grime and rock. The remaining 5 tubes will likely be used to measure the cleanliness of the sampling system, NASA mentioned in a statement (opens in new tab).Â

NASA scientists are particularly searching for samples from places that will have harbored microbial life billions of years in the past, hoping traces of those microbes might nonetheless be detectable within the materials. NASA and the European Area Company will work collectively to collect Perserverance’s samples and deliver them to Earth for detailed research, 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, preserving one inside its stomach. The first objective is for the rover itself to ship the samples to an incoming NASA lander, which is able to 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However in case Perseverance, which on the time of the pattern return mission’s arrival could possibly be over 10 years outdated, will get caught someplace, a pair of helicopters, which is able to arrive with the lander, will accumulate the backup samples and take them to the return car, according to NASA (opens in new tab).Â
Perseverance dropped its first sample at Three Forks on Dec. 21. The entire operation was rather more technically demanding than it may need checked out first look. For instance, the bottom management workforce needed to be sure that the pattern tubes have 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 mentioned within the assertion.Â
In keeping with an earlier Perseverance Twitter thread (opens in new tab), scientists will not be fearful that infamous Martian dust storms might fully bury the dear tubes in grime over the following decade. And in case a lot dust collects on the tubes that they’re now 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 problem,” the rover workforce said in a tweet (opens in new tab) final month.
