The quad means has been running various prelaunch tests on the rocket , formally known as the Space Launch System ( SLS ) , since April 1 , two weeks after itwas convey out to Pad 39Bat NASA ’s Kennedy Space Center ( KSC ) in Florida . NASA hope that the tests , get it on as the " fuddled apparel rehearsal , " would take less than 48 hours to complete , but two week and three trials subsequently , the agency has decided to bring the 322 - foot - tall ( 98 meters ) rocket back at bottom .
The sozzled dress rehearsals were being perform to ready the globe ’s most powerful rocket for the upcomingArtemisI flight , which will see the SLS fire an uncrewed Orion capsule around themoonand back in readying for later on crewed missions . But after thecolossal rocket inched its way out onto the launch pad , NASA engineer ’ attempt to load it with propellent and prepare it to the point of kindling fail . NASA has identified the main problems as a faulty helium check valve and a melted hydrogen escape and hopes to repair the issues through improvements to both the supply system of rules and the rocket , the agencysaid in a argument .
The sunrise casts a warm glow around the Artemis I Space Launch System (SLS) and Orion spacecraft at Launch Pad 39B at NASA’s Kennedy Space Center in Florida on March 21.

The authority insists that , aside from these " nuisance " payoff , the arugula is hunky-dory .
" The Mega Moon rocket is still doing very well . The one hindrance valve is literally the only literal subject we ’ve seen so far . We ’re very proud of the arugula , " Tom Whitmeyer , a deputy associate administrator at NASA headquarters in Washington , D.C. , tell at a printing press conference on Monday ( April 18 ) . " But we have a little moment more work in front of us . "
NASA engineers look to roll the rocket back inside the Vehicle Assembly Building by April 26 , where they will replace a defective atomic number 2 check valve on the rocket ’s upper level that prevented ground crews from loading it with supercooled limpid oxygen and liquid atomic number 1 .
Work on the rocket engine is expected to take most of May to nail . The time need to do these repairs will open a window for NASA ’s gaseous nitrogen supplier , Air Liquide , to promote its off - site system , and for the space agency to fix a leak on the the mobile launching towboat ’s can service mast umbilical , which feeds the arugula propellent and electrical energy while it is on the launchpad . The repairs will also give NASA engineers time to review the results of the miscarry soused attire attempt , reappraise the test agenda and decide on any further checks to make before undertake launching .

But despite the setbacks , NASA is sure-footed that the lunation rocket , which is more than 11 years and $ 30 billion in the qualification , will be quick shortly .
" We ’ll utterly go back out [ to the launchpad ] . We ’re absolutely run low to do a wet dress rehearsal , " Whitmeyer allege . " It ’s just a matter of what ’s the right time , what ’s the ripe way to do that . "
Once the rocket engine finally lifts off for its initiatory missionary station , it will venture on a 280,000 - mile ( 450,000 - km ) round tripper around the moonshine , going farther than any space vehicle build to carry humans has ever gone before , according to NASA . Artemis I will then be succeed by Artemis II , which will make the same flyby but with human passenger , and Artemis III , which will send humans back to the moon ’s open — includingthe first woman and the first someone of colour .
