The launch of NASA’s upcoming Mars rover has been pushed back again but yet again.
The vehicle-measurement Perseverance rover, the centerpiece of NASA’s daily life-looking Mars 2020 mission, will carry off no previously than July 30, 8 times later on than the former target day, agency officials declared right now (June 30).
“A liquid oxygen sensor line presented off-nominal information all through the wet dress rehearsal, and more time is essential for the team to examine and examine,” NASA officers wrote in an update these days, outlining the induce of the hold off.

The launch staff performed the wet gown rehearsal, a detailed countdown follow session with Mars 2020’s United Launch Alliance Atlas V rocket, at Cape Canaveral Air Pressure Station in Florida on June 22.
Mars 2020’s primary launch window extended from July 17 to Aug. 11. The “no previously than” day has been pushed again three periods — initial to July 20 simply because of a faulty crane, then to July 22 to take care of a potential contamination difficulty with ground assist lines, and now to July 30.
But there’s a nugget of good news in the most recent update as effectively: Mars 2020 has a bit additional time to get off the ground than initially assumed.
“Flight examination groups have expanded the mission start chances to August 15 and are examining if the start period may possibly be extended more into August,” NASA officials wrote these days.
Mars missions have limited launch windows for the reason that Earth and the Crimson World align properly for interplanetary vacation just when each and every 26 months. If the $2.7 billion Mars 2020 simply cannot get off the floor this summer months, the mission will have to be set into storage right up until autumn 2022. That destiny befell the European-Russian ExoMars rover Rosalind Franklin, which encountered problems with its parachute method and other challenges that could not be solved in time for a 2020 start.
Whenever it launches in the course of the coming window, Perseverance will land inside Mars’ Jezero Crater on Feb. 18, 2021. The six-wheeled robot will hunt for symptoms of historical existence in the 28-mile-broad (45 kilometers) Jezero, which harbored a lake and river delta billions of a long time in the past.
Perseverance will also accumulate and cache various dozen samples, which will be returned to Earth, possibly as early as 2031, in a joint exertion by NASA and the European Place Company. The rover will also examination out a number of new exploration systems, like equipment that generates oxygen from Mars’ skinny, carbon dioxide-dominated ambiance and a minor helicopter named Ingenuity.
