NASA says it’s going to be compelled to prolong the release of its multibillion-dollar Perseverance venture to no previous than July 30. The Mars-bound huge rover will have to release on an Atlas V rocket from Cape Canaveral Air Power Station in Florida prior to the center of August, or it’s going to leave out Earth’s conjunction with the purple planet.
That is the 3rd prolong within the release marketing campaign for Perseverance, previously referred to as Mars 2020, and essentially the most relating to as a result of a brand new, formal release date has now not been set.
An issue arose all through a Rainy Get dressed Practice session check previous this month. All through this usual prelaunch check, an Atlas V rocket is fueled with propellant and a countdown is performed till the overall moments prior to ignition. So what came about? “A liquid-oxygen sensor line offered off-nominal information all through the Rainy Get dressed Practice session, and extra time is wanted for the group to check up on and assessment,” NASA stated in a commentary on Tuesday afternoon, in keeping with a question from Ars.
A supply in Florida indicated that the problem was once associated with the Atlas V rocket’s Centaur higher level, which is fueled with liquid hydrogen and liquid oxygen.
Increasing release window
The $2.1 billion rover is very similar to NASA’s Interest rover however incorporates a number of upgrades, together with the addition of a small helicopter, and it’s going to release at the 541 configuration of the Atlas V rocket. NASA in the beginning set a release window from July 17 to August 11, the optimum length for the rocket to release, and for Perseverance to achieve Mars inside about six months.
The release has since been behind schedule from July 17 to July 20 because of a crane factor all through the stacking procedure; it was once once more behind schedule from July 20 to July 22. NASA attributed the latter setback to “a processing prolong encountered all through encapsulation actions of the spacecraft.”
The spacecraft has but to be stacked on best of the Atlas V rocket’s first and 2d levels. It now turns out most probably that the rocket’s producer, United Release Alliance, will wish to perceive and deal with the problem with the liquid-oxygen sensor line prior to that job can continue. As soon as the rocket and its payload achieve the release pad, the venture may even need to deal with summertime climate in Florida, the place storms alongside the coast are not unusual.
On Tuesday, the gap company stated it had prolonged the release window to August 15 and can read about whether or not the release window may also be prolonged a couple of extra days into August. If the Perseverance venture misses this release window, it could be behind schedule 26 months, at a value of masses of thousands and thousands of bucks, till the following Earth-Mars conjunction in 2022.
