The launch of NASA’s subsequent Mars rover has been pushed again but once more.
The car-size Perseverance rover, the centerpiece of NASA’s life-hunting Mars 2020 mission, will elevate off no sooner than July 30, eight days later than the earlier goal date, company officers introduced at present (June 30).
“A liquid oxygen sensor line offered off-nominal knowledge in the course of the moist gown rehearsal, and extra time is required for the crew to examine and consider,” NASA officers wrote in an replace at present, explaining the reason for the delay.

The launch crew carried out the moist gown rehearsal, a complete countdown observe session with Mars 2020’s United Launch Alliance Atlas V rocket, at Cape Canaveral Air Drive Station in Florida on June 22.
Mars 2020’s authentic launch window prolonged from July 17 to Aug. 11. The “no sooner than” date has been pushed again 3 times — first to July 20 due to a defective crane, then to July 22 to resolve a possible contamination concern with floor help traces, and now to July 30.
However there is a nugget of excellent information within the newest replace as nicely: Mars 2020 has a bit extra time to get off the bottom than initially thought.
“Flight evaluation groups have expanded the mission launch alternatives to August 15 and are inspecting if the launch interval could also be prolonged additional into August,” NASA officers wrote at present.
Mars missions have restricted launch home windows as a result of Earth and the Crimson Planet align correctly for interplanetary journey simply as soon as each 26 months. If the $2.7 billion Mars 2020 cannot get off the bottom this summer season, the mission should be put into storage till autumn 2022. That destiny befell the European-Russian ExoMars rover Rosalind Franklin, which encountered issues with its parachute system and different points that might not be solved in time for a 2020 launch.
Each time it launches in the course of the coming window, Perseverance will land inside Mars’ Jezero Crater on Feb. 18, 2021. The six-wheeled robotic will hunt for indicators of historical life within the 28-mile-wide (45 kilometers) Jezero, which harbored a lake and river delta billions of years in the past.
Perseverance will even gather and cache a number of dozen samples, which shall be returned to Earth, maybe as early as 2031, in a joint effort by NASA and the European House Company. The rover will even take a look at out a number of new exploration applied sciences, together with gear that generates oxygen from Mars’ skinny, carbon dioxide-dominated environment and a little helicopter named Ingenuity.
