It was a lucky change in early August when Perseverance made its first attempt to obtain the sample, but scientists found that nothing had ended up in the collection tube. The falling mechanism unfortunately turned the brittle stone into dust, which fell to the ground near the drilling hole. Rochette was chosen in part because of the harder rock there and the greater tendency to be trapped in the pipe.
Why it’s a great thing: Collecting samples is one of the main goals of the mission. Persistence is equipped with 43 collection tubes, and NASA expects to fill it with samples of rocks and soil from Earth to return to Earth one day. The 28-kilometer-long Jezer crater is believed to be the site of the old delta of the river. If Mars had ever lived in its wet ages billions of years ago, this is one of the best places where fossilized habitat has found its home. Although the character is armed with tools that will tell us what is happening in Jezero, the best way to look for biosignatures and traces of microbial life is in the Earth lab.
