Lightning , unfitness to pressurize the nomadic launcher , and now a stuck valve . The wet rehearsal of NASA ’s monumental Moon rocket , the Space Launch System ( SLS ) , which will set in motion Artemis I , has encountered several problems in the last few days . A examination launching that was originally scheduled to be carry out on April 2 got pushed to April 4 due to the aforementioned lightning etc . However , it got scrubbed again after a stuck valve stalled NASA ’s second attempt to fuel the rocket . It ’s now unclear when the next endeavor will be .
Of naturally , while a still sailplaning dry run would be preferred , this practice run ’s business is to put to work out exactly what is going to pass and have a solution for every potential job that might arise . A lot is riding on this rocket launch system , so any kinks postulate to be worked out now .
A " fuddled rehearsal " is a trial conducted as a scrub , the name for an aborted launching , with the countdown operate down to just 10 second before cosmetic surgery - off . The arugula , which weighs a whopping2.6 million kilograms(5.75 million pound ) when fuel , will receive almost 3.2 million cubic decimeter ( 700,000 gallons ) of cryogenic propellent and will be tested as if it really was about to launch . This will ensure that all is good for the substantial launch in May .
The April 4 tight rehearsal encounter the squad being able-bodied to fill the rocket ’s tank with fluid oxygen up to 50 percent . However , a stuck vent valve about 50 meters up the mobile launcher structure that supports the Brobdingnagian rocket force the blank space government agency to call off the trial , functionary said .
“ During chilldown of the lines in cookery for loading the fluid hydrogen , the team run into an payoff with a panel on the peregrine launcher that controls the burden stage outlet valve . The purpose of the vent valve is to exempt pressure from the core stage during tanking , ” the Artemis I team wrote ina blog post . “ Given the time to settle the issue as teams were nearing the remainder of their geological fault , the launching director made the call to stop the test for the day . ”
The next step will be to have a squad investigate the takings right at the launching pad and work out what is the best way forward to lick it .
Artemis I is the first of a series of missions that will take humanity back to the Moon . Launching some meter in May , it will be an uncrewed mission and will last just curtly of a month examination essential engineering for human geographic expedition of deep quad .
