NASA’s Moon Mission Test Triumphs After Prior Catastrophic Failure—What Went Right This Time?

NASA’s Moon Mission Test Triumphs After Prior Catastrophic Failure—What Went Right This Time?

So NASA’s Artemis II mission just nailed its ‘wet dress rehearsal’ on the second try—because who doesn’t love a good comeback story? The first run got the boot thanks to a sneaky liquid hydrogen leak that stopped the countdown at T-minus 5:15. But after some tinkering and a bit of that classic space-age elbow grease, they loaded over 700,000 gallons of fuel without bursting a sweat—or a pipe. Funny enough, experts were already expecting this hydrogen hiccup; apparently, NASA’s got a little leak budget that they smartly banked on this time around. Still, even with a shaky moment where communications took a quick nap, the team kept their cool and pushed through. Now, while the astronauts prep to quarantine, the whole world’s holding its breath for launch day to get the green light. Makes you wonder—if controlling a rocket this massive is this tricky, what’s next? Maybe teaching it to make coffee before liftoff? LEARN MORE

After having to call things off previously the ‘wet dress rehearsal’ for NASA’s Artemis II mission has been carried out successfully second time around.

The first attempt had to be cancelled at T-5:15 minutes due to a liquid hydrogen leak, so NASA conducted repairs and set it up for a second attempt yesterday (19 February).

Jordan Bimm, Assistant Instructional Professor of Science Communication at the University of Chicago, had told LADbible had been anticipating this problem and went into the first test thinking ‘we’re gonna hear about a hydrogen leak’.

He explained that NASA has ‘an allowance for a certain amount of hydrogen to leak out’, and this time they have done it.

NASA announced they ‘successfully fuelled its SLS (Space Launch System) rocket and demonstrated the launch countdown’ as part of preparations for the mission itself.

A successful test for Artemis II

Over 700,000 gallons of liquid propellant was loaded into the rocket while a crew, not the actual crew set to fly it on the big day, closed all of the spacecraft’s hatches.

NASA said the liquid hydrogen fuelling had ‘proved challenging during previous tests’ but this time they ‘remained under allowable limits’ which has given them confidence in new seals which were installed.

That’s not to say things went off without a hitch, as NASA explained there had still been some problems with the wet dress rehearsal.

They said: “Early in fuelling operations, teams experienced a loss of ground communications in the Launch Control Center.

“Operators temporarily moved to backup communication methods to maintain safe propellant loading activities before normal communications channels were restored. Engineers isolated the equipment that caused the issue.”

Still, it’s considered a successful test ahead of launch.

The Artemis II crew goes into quarantine

NASA said they expect the Artemis II crew, who observed the test, to go into quarantine today ahead of a potentially green light for the mission.

There has been no formal launch date set, but the astronauts need to be in quarantine for roughly 14 days before they set off for space.

It doesn’t mean they’re launching in March, but it keeps the option open should conditions permit it.

NASA had identified 6 March as the earliest possible opportunity for launch.

The Artemis II mission

The mission itself plans to send the crew of astronauts into space where they will orbit the Earth before setting off around the Moon.

They will go further round the far side of the Moon than anyone has ever gone before, and depending on their launch date it’ll be the furthest human beings have ever made it into space.

“It comes down to which launch window they pick. I don’t want to take away from how historic this is, how risky it is, how daring it is,” Professor Bimm said.

“I think for me that’s the real accomplishment, not did they get the extra five, 10 on the yardstick.

“We tried this really hard thing that hasn’t been done in a really long time and we’re doing it in a new way with a new vision of what to do there.

“Our astronauts this time are gonna be higher up, they’re gonna see more of the surface of the moon out the window and they’re gonna do some cool human-eye observations of that.”

Now we wait for NASA to announce the launch date.
