Though small compared to America's hulking, car-sized 1,025-kilogram (2,260-pound) Perseverance, it's almost twice as big as the two rovers China has sent to the moon in 2013 and 2019. Perseverance is expected to operate for at least two years. This Mars-launching season — which occ...
Landing on Mars is notoriously difficult. Only the U.S. has successfully landed a spacecraft on Martian soil, doing it eight times since 1976. NASA's InSight and Curiosity rovers still operate today. Six other spacecraft are exploring Mars from orbit: three American, two European and one fro...
Here are the key steps in the landing of Perseverance on Mars. (Image credit: NASA/JPL-Caltech) A rover's mission Perseverance's mission on Mars will last at least one Martian year, or 687 Earth days. Mars rovers can far outlive their planned missions, however. NASA's Curiosity rover,...

“If there’s one thing we know, it’s that landing on Mars is never easy,”saidMarc Etkind, NASA’s associate administrator for communications. “But as NASA’s fifth Mars rover, Perseverance has an extraordinary engineering pedigree and mission team. We are excited to invite the entire wor...
DLearning more about the makeup of the land on Mars is very important for protecting NASA's rovers(探测车). In2009, a rover called Spirit got stuck in a sand trap on Mars and never managed to get out.NASA's Curiosity Rover has been on Mars for eight years. Its camera has sent back...
“The Perseverance team is putting the final touches on the complex choreography required to land in Jezero Crater,” said Jennifer Trosper, deputy project manager for the mission atJPL. “No Mars landing is guaranteed, but we have been preparing a decade to put this rover’s wheels down...
Until Perseverance, NASA sought out flat, boring terrain on which to land –“one giant parking lot,” Chen said. That’s what China’s Tianwen-1 rover will be shooting for in Mars’ Utopia Planitia. NASA is upping its game thanks to new navigation technology designed to guide the rove...
In the past century, scientists and researchers have explored the depths of the ocean, landed rovers on Mars, and developed a deeper understanding of the human brain and body. In the wake of these discoveries and in the age of Google Maps and GPS, one would think that we have explored ...
