Since it was launched in February 2021 on Mars, Perseverance collected dust, rock and even air from Red Planet. The rover analyzes many of them by itself and collects other stuff in titanium test tubes to send them to the Earth in the future.

A mission called Mars Sample Return is still in the planning stage. Perseverance is expected to hand the samples over to robotic landers, which will place the test tubes in a special capsule in a small rocket. The capsule will move to another spacecraft that will try to get scientific samples from Earth (like to hunt for signs of life on the Red Planet), and investigate the possibility of it for a single day.

There’s a plan for a certain emergency in case a problem arises before the Sample Return robot arrives. The rover drops a pair of random samples, which includes a “fork” in the lake Crater, where special helicopters will then pick up the samples. On December 21st, Perseverance left there the first test tube with a sample of igneous rock, which he collected from South Seytakh on January 31st.

Perseverance received a vial, checked the CacheCam and then threw it 89 cm away. Next, a WATSON camera, equipped with one of the two-meter robotic arms of the rover, checked the slideability and did not roll away.

Approximately the next two months, the remaining nine canels will be thrown into the Three Forks.
