So apparently the issue was one of the fourt engines wasn't cooling to the necessary temperature.

On investigation, they believe it was a faulty temperature sensor, not actually anything to do with the cooling process.

@NTA I hope it wasn't one of those cases where a faulty 50c part halted a multi-million dollar liftoff!! But I'd rather a faulty part than a big engine issue.

lol what are the chances that sensor actually costs a shit-ton

Probably cost a couple of bucks but NASA pay thousands

Given the Artemis uses an enhanced version of a design first flight certified over four decades ago, and that temperature was the issue behind he integrity of the Challenger's O-rings, I can understand NASA's reticence. It's expensive because of the engineering required to operate in such extremes.

@antipodean oh shit, yeah no wonder they were erring on the side of caution. What a cool but kinda nightmare fuel job to be working on a gnarly project like this.

@Paekakboyz I can tell you from personal experience; if the sensor was made by Audi, it'll cost at least two shit-tons

But fuck me if it blows up on the pad it'll be awesome to see.

Well the whole American rocket industry was heavily reliant on Ze Germans in the early days, so....

NASA gets Voyager 1 talking again — and discovers a new mystery

14.6 billion miles from one another, NASA engineers have found and fixed a computer glitch that had caused Voyager 1 to transmit garbled telemetry data since May.

Artemis 1: Nasa’s moon rocket springs hazardous leak ahead of launch

Fuel leak comes after Nasa fixed an engine issue that postponed the original launch attempt five days earlier

Nasa was poised to make a second attempt to fly its pioneering Artemis 1 moon rocket on Saturday afternoon after the US space agency declared it had identified and fixed an engine issue that caused the postponement of the original launch attempt five days earlier.

But the new moon rocket sprang another hazardous leak Saturday, as the launch team began fueling it for liftoff on a test flight that must go well before astronauts climb aboard.

As the sun rose, an over-pressure alarm sounded and the tanking operation was briefly halted, but no damage occurred and the effort resumed, Nasa’s Launch Control reported. But minutes later, hydrogen fuel began leaking from the engine section at the bottom of the rocket. Nasa halted the operation, while engineers scrambled to plug what was believed to be a gap around a seal.
