Answer: NASA's Mars 2020 Perseverance rover is searching for signs of ancient microbial life on Mars and collecting core samples of Martian rock and regolith (broken rock and soil). The samples are for potential pickup by a future mission that would bring them to Earth for detailed study.

Distance record

Since it landed on the Red Planet in 2021, Perseverance has driven farther, faster than any vehicle ever has on the surface of another world. On Oct. 11, its odometer reached 28.10 miles (45.22 kilometers), rolling past the record of 28.06 miles (45.16 kilometers) set by NASA's Opportunity rover (2004-2018). Perseverance covered the ground in about 5½ years, compared to almost 15 for its predecessor.

Science instruments

Perseverance's instruments are designed to acquire information about Martian geology, atmosphere, environmental conditions, and potential biosignatures.

• Mastcam-Z is the mast-mounted camera system with a zoom function. Its cameras can zoom in, focus, and take 3D pictures and video at high speed to allow detailed examination of distant objects.
• The Mastcam-Z cameras sit on the rover mast at the eye level of a 6 ½-foot-tall person (2 meters tall), separated by 9.5 inches (24.2 centimeters) to provide stereo vision.
• The mast head contains the SuperCam instrument; the two Mastcam-Z imagers sit beneath the masthead.
• The rover's two navigation cameras sit on the exterior sides of the Mastcam-Z imagers.
