In February, NASA showed how it will collect samples from Mars and bring them to Earth as part of the Mars 2020 Mission. ESA released more details on this task, at a time when NASA’s rover is due to launch between July and August this year.
The two space agencies will collaborate in the different phases of the mission. The process involves the development of the lander, the collection rover, an upward vehicle to launch the sample deposit into the Martian orbit, as well as the spacecraft that will return to Earth with the precious cargo.
Regarding the NASA rover, already called Perseverance, it has a drill on the end of the robotic arm and will drill the soil and obtain the samples for tubes that are stored inside the rover.
After collecting a set of samples, Perseverance drops them on the surface for collection. This is where the lander comes in, the vehicle that has the instruments. the Sample Fetch Rover and the Sample Transfer Arm to transfer the samples to a rocket and the Mars Ascent Vehicle, used to transport the samples from the planet to space.
