The Rover “Perseverance” system of processing of soil samples

The Rover “Perseverance” (Perseverance) future NASA mission “Mars-2020” received two major components of the system of receiving and storage of soil samples: carousel with drill bits and machinery moving and storage tubes. The launch mission, scheduled for this summer, yet was postponed due to the pandemic coronavirus, reported on the website of the jet propulsion Laboratory of NASA.

The start of the mission “Mars-2020” in the space scheduled for the period from 7 July to 5 August 2020, and landing on the planet’s surface must be done on 18 February 2021. Mars will leave the Rover, named “Perseverance” (Perseverance, “Perseverance”): it is based on the design of “Curiosity” and has an expanded set of scientific instruments, including 23 cameras. Also during the mission on Mars will send unmanned aircraft Mars Helicopter. Devices will work in the crater Lake, where in the past the river Delta and you can find clay minerals and carbonates that could have formed in the presence of liquid water and keep traces of ancient Martian life. In addition, the Rover will study the climate of Mars, to collect sample images of the soil for subsequent delivery to the Earth and be able to try out technologies that are used in future manned missions to Mars, such as the production of oxygen from the atmosphere.

Currently concluding work on the Rover and test all its systems at Kennedy Space center NASA in Florida: a pandemic coronavirus have not yet impacted the project schedule. March 3, 2020 for the Rover system was installed ACA (Adaptive Caching Assembly), consisting of seven engines and more than three thousand parts. Its main component is a manipulator, to move the filled sampling tube in a sealed vault. March 7, on the top of the Rover installed the carousel containing nine different nozzles for drilling rig: two for the abrasive cleaning of the upper layers of rocks, one sample of regolith and six for obtaining cores. Before starting work, the mechanism provides supply or chisel, or, in the case of core samples, drill bit and sampling tube, which is then moved to the system analysis of the samples. The drilling nozzle after use is returned back to the carousel.

Finally, on March 11, installation was completed and testing of electrical wiring for both systems. After a couple of months the Rover will load a set of clean sampling tubes, after which the system receiving and storing the soil sample will be completely ready to work.
