Perseverance er en marsbil opsendt som en del af NASA's Mars 2020-mission, — NASA's til dato mest komplekse marsmission. Marsbilen landede sikkert den 18. februar 2021 ved Jezero-krateret.[1]

Perseverance blev sendt op den 20 juli 2020 fra Cape Canaveral Space Force Station i Florida og rejste 203 dage og 472 millioner kilometer for at nå frem.[1] Selve landingen blev optaget på video, hvor man ser faldskærmens udfoldelse, deaccerelering, varmeskjoldets afkobling, landingsmotorens indkobling, afkobling fra bagskjoldet, terrænnavigering og nedhejsning af Perseverance.

Marsbilen har dansk involvering igennem PIXL-kameraet.[2]

PIA24426: Animation: How Perseverance's SuperCam Works

This narrated animation shows NASA's Perseverance rover on Mars and how the rover's SuperCam laser instrument works.

SuperCam is led by Los Alamos National Laboratory in New Mexico, where the instrument's Body Unit was developed. That part of the instrument includes several spectrometers, control electronics and software.

The Mast Unit was developed and built by several laboratories of the CNRS (French research center) and French universities under the contracting authority of CNES (French space agency). Calibration targets on the rover deck are provided by Spain's University of Valladolid.

JPL is building and will manage operations of the Mars 2020 rover for the NASA Science Mission Directorate at the agency's headquarters in Washington.

Perseverance Rover's Descent and Touchdown on Mars Onboard Camera Views .webm
NASA's Mars 2020 Perseverance mission captured thrilling footage of its rover landing in Mars' Jezero Crater on Feb. 18, 2021. The real footage in this video was captured by several cameras that are part of the rover's entry, descent, and landing suite. The views include a camera looking down from the spacecraft's descent stage (a kind of rocket-powered jet pack that helps fly the rover to its landing site), a camera on the rover looking up at the descent stage, a camera on the top of the aeroshell (a capsule protecting the rover) looking up at that parachute, and a camera on the bottom of the rover looking down at the Martian surface.
The audio embedded in the video comes from the mission control call-outs during entry, descent, and landing.

Original Caption Released with NASA Image:

Photo from Viking Lander 2 shows late-winter frost on the ground on Mars around the lander. The view is southeast over the top of Lander 2, and shows patches of frost around dark rocks. The surface is reddish-brown; the dark rocks vary in size from 10 centimeters (four inches) to 76 centimeters (30 inches) in diameter. This picture was obtained September 25, 1977. The frost deposits were detected for the first time 12 Martian days (sols) earlier in a black-and-white image. Color differences between the white frost and the reddish soil confirm that we are observing frost. The Lander Imaging Team is trying to determine if frost deposits routinely form due to cold night temperatures, then disappear during the warmer daytime. Preliminary analysis, however, indicates the frost was on the ground for some time and is disappearing over many days. That suggests to scientists that the frost is not frozen carbon dioxide (dry ice) but is more likely a carbon dioxide clathrate (six parts water to one part carbon dioxide). Detailed studies of the frost formation and disappearance, in conjunction with temperature measurements from the lander’s meteorology experiment, should be able to confirm or deny that hypothesis, scientists say.
Perseverance's First Full-Color Look at Mars.png
This is the first high-resolution, color image to be sent back by the Hazard Cameras (Hazcams) on the underside of NASA’s Perseverance Mars rover after its landing on Feb. 18, 2021.

A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).

Subsequent missions by NASA in cooperation with ESA (the European Space Agency), would send spacecraft to Mars to collect these cached samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 mission is part of a larger program that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance and Curiosity rovers.
