PASADENA, Calif. (NASA PR) — With only about 50 million miles (80 million kilometers) left to go in its 293-million-mile (471-million-kilometer) journey, NASA’s Mars 2020 Perseverance rover is nearing its new planetary home. The spacecraft has begun its approach to the Red Planet and in 43 days, on Feb. 18, 2021, Perseverance will blaze through Mars’ atmosphere at about 12,100 mph (19,500 kph), touching down gently on the surface about seven minutes later.

HOUSTON (NASA PR) — Later this summer, NASA is launching the Mars Perseverance Rover to the Red Planet with the Mars 2020 Mission. The rover is loaded with equipment to search for signs that there once was life on Mars. One device, called the Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals (SHERLOC) instrument, will be used to detect chemicals on the Martian surface that are linked to the existence of life.

To keep the instrument working well, a team from the Astromaterials Research and Exploration Science (ARES) division at NASA’s Johnson Space Center (JSC) recently built a new calibration device for the rover to check SHERLOC’s function and properly tune it during the upcoming mission.
