CAPE CANAVERAL, Fla. — Not all space heroes put on spacesuits. Typically they put on exhausting hats.
NASA’s $4.1 billion Space Launch System (SLS) rocket sat ready on Launch Pad 39B right here at Kennedy Area Heart in Florida on Tuesday (Nov. 15) forward of launch when sensors detected yet one more fueling leak. Such leaks had been the bane of this rocket’s existence throughout earlier launch makes an attempt, and when one other leak arose throughout final evening’s countdown, it appeared to many who we might witness yet one more scrubbed launch — or worse, a rollback to the Car Meeting Constructing for repairs.
But that is not what occurred, because the spectacle within the Florida skies early on Wednesday morning (Nov. 16) proved. Because the world watched to see if this gas leak might be repaired, Artemis 1 mission managers made a dangerous determination: They’d ship a “Pink Crew,” a specialised workforce of technicians, to what engineers name “zero deck” on the base of the fueled rocket to attempt to cease the liquid hydrogen leak.
Fortunately, the Pink Crew was profitable.

The unsung heroes had been in a position to pull off the daring restore, and simply hours later Artemis 1 was on its method to orbit round the moon.
Trent Annis, one of many Pink Crew members, mentioned that though it was terrifying being beneath the fueled rocket, his workforce remained centered on the job at hand.
“I might say we had been very centered on what was occurring up there,” Annis advised NASA TV after the launch. “Simply ensuring we knew what was occurring. As a result of the rocket is, , it is alive, it is creaking, it is making venting noises, it is — it is fairly scary. So on zero deck, my coronary heart was pumping. My nerves had been going however yeah, we confirmed up at the moment.”
Annis and the opposite two members of the crew, Billy Cairns and Chad Garrett, had been despatched to the cellular launch platform on the base of SLS to tighten down “packing nuts,” {hardware} that helps type a decent seal on the replenishment valves by means of which liquid hydrogen was pumped into the Artemis 1 moon rocket’s core stage after the primary tanking process. As a result of hydrogen is such a small molecule, it manages to search out its manner out of even the tightest seals, that means NASA has to maintain replenishing the hydrogen gas tanks all through the launch countdown even after most important fueling procedures have been accomplished.
With Artemis 1’s launch window ticking away on Tuesday evening (Nov. 15), Cairns, Garrett and Annis arrived at the mobile launch platform (opens in new tab) beneath the extremely harmful SLS automobile at 10:12 p.m. EST (0312 GMT on Nov. 16) to cease the leak — and quick — or danger shedding this launch alternative. As soon as on the platform, the crew found that the packing nuts had been “visibly free,” in accordance with an announcement by launch commentator Derrol Nail on NASA TV’s media channel.
Fortunately, with nerves seemingly fabricated from metal, the Pink Crew carried out admirably, tightening the nuts and enabling the Artemis 1 launch countdown to renew.
“You already know, I nonetheless cannot imagine it. Like I mentioned it is actually simply superb,” Annis mentioned throughout the post-launch interview.
“We had lots of people right here serving to us out, a variety of groups, the fireplace room,” Annis mentioned. “I am positive that was hectic. And , NASA, Boeing, all the opposite corporations did an incredible job. We’re glad to be a part of that.” In a testomony to how uncommon the damaging process was, NASA TV commentators interviewing the Pink Crew added that Cairns mentioned he has served on the crew for 37 years and had by no means earlier than been known as in for a restore on a fully-fueled rocket earlier than final evening’s daring tour.
The Artemis 1 mission is now safely on its 25-day mission by means of deep space towards the moon, the place it would pave the best way for future crewed missions. The Orion spacecraft will attain the moon on Monday (Nov. 21) earlier than spending a number of extra days positioning into lunar orbit.
The mission will conclude on Dec. 11 when Orion will reenter Earth’s atmosphere at 25,000 mph (40,233 kph) and expertise temperatures as much as 5,000 levels Fahrenheit (2,760 Celsius) earlier than splashing down within the Pacific Ocean — hopefully with no Pink Crew wanted.
