Chinanews, July 22nd, a comprehensive report. On July 22nd, local time, the National Aeronautics and Space Administration (NASA) announced that preparations for the operation of collecting soil samples from Mars are in the final stage, and related operations are expected to take two weeks. Carried out within.

  According to previous reports, the Perseverance successfully completed a landing on Mars in February.

This is NASA's ninth probe to visit the surface of Mars, and it will also be the first probe to sample from Mars for return to Earth.

The rock and soil samples it collected from Mars will be brought back to Earth in other Mars exploration missions in the future.

Data map: May 12, 2021. NASA announced on May 12, local time, that the "Perseverance" used the Perseverance mast camera Mastcam-Z to take a photo of the Martian hill "Santa Cruz" on April 29.

  On July 22, NASA announced on its official website that the agency's preparations for collecting soil samples from Mars are in the final stage.

The source also stated that “an important phase of the mission is expected to take place within two weeks.”

  According to the report, considering the distance to Mars, the time required to send commands to the rover, and the complexity of the mission, Perseverance is expected to take 11 days to complete the first sampling of Mars samples.

  In addition, before the start of the drilling operation, the rover will carefully study the surface of the rock to be sampled in order to extract the required soil with the aid of the drilling tool and the "test tube" on the robotic arm.

  According to reports, the mission objectives of Perseverance also include searching for signs of life that may have existed on Mars in ancient times, exploring the geological and climatic characteristics of Mars, and exploring Mars accumulation technology for future robots and humans.
