After a pair of called-off launches, the latest caused by a large hydrogen leak, the agency is not expected to try again until later in the month or ...

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.

After technical difficulties disrupted NASA's Artemis I mission twice, its Space Launch System (SLS) rocket will not launch this week.

The termination system is part of the rocket that the NASA had 20 days in which to launch the rocket before it would have to be rolled back in order to test the batteries in the rocket’s flight termination system. Speaking soon after the second launch scrub on Saturday, NASA Administrator Bill Nelson said if the SLS rolls back into the VAB for repairs, the next launch attempt would most likely happen in mid to late October, after a planned crew mission to the International Space Station takes off earlier that month. The rocket was set to launch an uncrewed capsule called Orion on a mission called Artemis I. As noted by Sarafin, if NASA stayed on the pad, they could test the system at cryogenic temperatures, which would give them a better idea of how it would behave during a real launch. The announcement comes after two scrubbed launch attempts of the massive rocket, and will likely result in a delay of several weeks.

NASA postponed its Artemis I launch again, after making a second attempt to get the mission off the ground.

It's the first mission in NASA's Artemis lunar program, which is tentatively planned to land the agency's astronauts on the moon by its third mission in 2025. The agency said it will need to roll the 32-story tall rocket back to the Vehicle Assembly Building at Kennedy Space Center in Florida before another attempt. NASA made several attempts to fix the leak, but time ticked away ahead of the launch window that was set to open at 2:17 p.m. 17 and last about two weeks each. As NASA was filling the rocket on Saturday morning, the agency's team detected a hydrogen fuel leak from the engine section. 19 and Oct.

[The Moon is a jumping off point for Mars](/2022/09/03/moon-mars-nasa-artemis-missions) In this week's Markets Weekend, we dive into why America has such an acute labor shortage. [Artemis I](https://www.axios.com/2022/08/23/nasa-artemis-rocket-space-launch-system-launch) — is the first in NASA's bid to return people to the surface Moon for the first time since the end of the Apollo program. Why it matters: NASA is planning to launch its first test flight of its new Moon rocket today, marking one of the agency's first major steps along a decades-long journey to Mars. [surface of the Moon](https://www.axios.com/2022/09/03/moon-mars-nasa-artemis-missions) for the first time since the 1970s. - For this flight, the SLS is expected to send Orion on a journey around the Moon before the capsule comes back in for a landing on Earth, splashing down in the Pacific Ocean.

NASA wants to send the crew capsule atop the rocket around the moon, pushing it to the limit before astronauts get on the next flight.

The new moon rocket uses the same type of main engines. During Monday’s attempt, a series of small hydrogen leaks popped up there and elsewhere on the rocket. Ground controllers tried to plug it the way they handled previous, smaller leaks: stopping and restarting the flow of super-cold liquid hydrogen in hopes of closing the gap around a seal in the supply line. If the six-week demo succeeds, astronauts could fly around the moon in 2024 and land on it in 2025. After the latest setback, mission managers decided to haul the rocket off the pad and into the hangar for further repairs and system updates. That was on top of leaks detected during countdown drills earlier in the year.
