It was not immediately clear if space agency will be able to make fixes in time to meet next backup launch date of Monday.

Officials said they had identified that problem as a faulty sensor rather than an issue with the cooling system or engine itself. “This is part of the space business,” he said. It was the second time in five days that technical issues had kept the spacecraft on the launchpad.

The rocket is to propel an uncrewed Orion capsule to the moon. It’s the first launch of a new complex rocket and there are likely still bugs to be worked out. There are opportunities on Monday and Tuesday, but if the agency is not able to pursue them, it would have to wait until possibly mid-October, Mr. “Be ready for the scrubs.” They tried several times to fix it before the launch director, Charlie Blackwell-Thompson, decided at 11:17 a.m. Kenneth Chang has been reporting on NASA and spaceflight since the 1990s.

The US space agency Nasa has again postponed the planned launch of its new moon rocket due to technical issues. The new rocket, known as the space launch ...

The current mission, known as Artemis 1, is uncrewed and is essentially a test flight to put the various parts of the system through their paces. This could lead to a delay of several weeks in the launch. This is the second time in a week that Nasa has been forced to cancel the planned launch.

A fuel leak that thwarted NASA's second attempt to launch its new Artemis 1 moon rocket on Saturday (Sept. 3) will likely take weeks to fix.

It's unclear at the moment if the mission team plans to seek such a waiver. Ten tiny cubesats are flying on Artemis 1, to conduct a variety of science work and test various technologies. The leak occurred after a brief "inadvertent" overpressurization of the fuel line that was three times the acceptable pressure, said Mike Sarafin, NASA's Artemis 1 mission manager. But they stressed that calling off the launch today was the right move, as did NASA Administrator Bill Nelson, who also participated in the briefing. The Saturday leak occurred near the base of the SLS rocket in what NASA calls a "quick disconnect," a fitting that connects a liquid hydrogen fuel line to the core booster to fuel it for launch. — A fuel leak that thwarted NASA's second attempt to launch its new Artemis 1 moon rocket on Saturday (Sept. One thing is clear, however: The quick disconnect's soft seal gasket will likely have to be replaced. The leak led to levels of flammable hydrogen gas near the rocket that were several times higher than the acceptable range, he added. 3) will likely take weeks to fix, and may even force the megarocket off its launch pad, space agency officials said. Despite three separate tries to fix the leak, engineers weren't able to stem it and ultimately stood down to assess the situation further.

One was to simply disconnect and reconnect the fuel line and attempt to launch again in a couple of days. He called the scrub “bittersweet” but hedged that they had begun the day with “the same expectations of ‘probably won’t happen.’” The mission managers decided the gasket would be need to be replaced, and engineers are considering whether it would be better to do that work at the launchpad, where they could then run liquid hydrogen through the line to ensure the fix was successful, or first roll the rocket back to a behemoth structure known as the Vehicle Assembly Building. Monday’s launch was called off when a faulty sensor reported that one of the rocket’s four core-stage engines was not sufficiently chilled. — For the second time in a week, NASA officials on Saturday called off the test launch of a rocket that is to one day carry astronauts to the moon. The scrubbed launch is for Artemis I, a weekslong, uncrewed mission that will test the rocket and the capsule where future astronauts will ride. Sarafin said that the problem might have been related to an incorrect command sent to the propellant-loading system on the launchpad, causing overly high pressures — 60 pounds per square inch instead of 20 — in the fuel line for a few seconds. After three attempts to seal the leak failed, the launch attempt was called off at 11:17 a.m. That could have damaged the gasket in the connector. NASA has already spent more than $40 billion to develop the rocket, known as the Space Launch System, and the capsule, known as Orion. The moon landings half a century ago were part of NASA’s Apollo program. Kenneth Chang has been reporting on NASA and spaceflight since the 1990s.
