NASA’s rhinoceros-size Perseverance rover pulled off essentially the most exact touchdown in Martian historical past Thursday (Feb. 18), touching down efficiently in Jezero crater. The touchdown put the cell robotic laboratory in place to start the hunt for indicators of long-lost life within the historic remnants of a river delta that after flowed via the area.
The two,260-pound (1,025 kilograms) machine radioed dwelling a sequence of quick chirps throughout its meteoric plunge into the Martian ambiance, indicating success throughout every of the complicated maneuvers that have been required to soundly deposit its bulk on the floor. (Reside Science detailed these maneuvers right here.) The ultimate stage of the touchdown concerned a never-before-used robotic skycrane that guided the rover to a protected touchdown location and introduced its plunge to a whole halt earlier than decreasing it 65 ft (20 meters) to the floor utilizing cables. Relaying its sign via the Mars Reconnaissance Orbiter (MRO) satellite tv for pc, the rover reported that it was on the floor and protected at 3:56 p.m. ET.

“Landing success! Perseverance has landed on Mars,” stated Swati Mohan, steering and management operations lead for the mission and NASA’s mission commentator on NASA TV’s dwell stream throughout the occasion.
A video feed confirmed the Jet Propulsion Laboratory’s entry, descent and touchdown group erupting with cheers when Perseverance despatched its chirp of success, which arrived after a 15-minute delay because of the distance between Mars and Earth and a specific amount of lag from the MRO.
Perseverance hasn’t but despatched any photos dwelling, although they need to be coming within the following hours and days. NASA mounted cameras and a microphone on the descent automobile and rover to file the touchdown. The massive video recordsdata might take as much as per week to totally add throughout interplanetary area, NASA stated.

Perseverance’s life-hunting mission implies that the rover is kind of a $2.7 billion nuclear-powered geologist, carrying a giant toolbelt of devices to exactly observe the compounds current within the crater’s minerals, searching for indicators of historic life. It additionally carries a ground-penetrating radar to review the subsurface geology of the area and an experiment designed to provide oxygen from Martian carbon dioxide — a proof of idea of a expertise that might possible be a key part of any future crewed Mars missions. The rover will even gather samples that NASA hopes to return to Earth utilizing a future joint mission with the European House Company.
A pigeon-sized helicopter named Ingenuity rode to the floor hooked up to Perseverance’s stomach. It is also a proof-of-concept experiment, the aim being to attain the primary powered flight on Mars.
All of that may take time to stand up and working, nonetheless. For now, NASA can breathe a sigh of reduction that its massive mission wasn’t destroyed on affect.
