Artemis launch

NASA began fueling its massive new rocket early Saturday (Sept. 3), setting the stage for a critical Artemis 1 test flight to the moon.

NASA is encountering new problems with its second attempt to launch its massive Space Launch System rocket and Orion spacecraft to the moon.

This time, they used helium to pressurize the line, but this did not work either. They also started loading the liquid hydrogen, but at about 7:15 a.m. But when they started to reflow the hydrogen, they noticed another leak.

NASA's 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 ...

The launch team planned to ignore the faulty sensor this time around and rely on other instruments to ensure each main engine was properly chilled. If not, the resulting damage could lead to an abrupt engine shutdown and aborted flight. On Monday, hydrogen fuel escaped from elsewhere in the rocket. People last walked on the moon 50 years ago. 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. But minutes later, hydrogen fuel began leaking from the engine section at the bottom of the rocket.

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.

NASA canceled its second Artemis I launch attempt to the moon on Saturday, after encountering a stubborn liquid hydrogen fuel leak that couldn't be stemmed.

Next, engineers tried to repressurize it with helium, and then returned to the warm-and-chill method to stop the leak. — NASA called off the second attempt to launch an ambitious test flight of its new moon rocket on Saturday (Sept. 3), this time because of a stubborn leak that delayed fueling.

For the second time in five days, NASA halted a countdown in progress for the debut flight of its next-generation rocket in the moon-to-Mars program.

SLS has been under development for more than a decade, with years of delays and cost overruns. Many experts, however, believe that time frame is likely to slip by a few years. But NASA officials have yet to make that call. But pre-flight operations were officially called off for the day by Artemis I launch director Charlie Blackwell-Thompson about three hours before the start of that window. NASA chief Bill Nelson said mission managers would convene later in the day to discuss a future launch opportunity, adding there was a chance that the rocket might be rolled back to its assembly building for further trouble-shooting and repairs. For the second time in five days, the US space agency halted a countdown in progress and postponed a planned attempt to launch the debut test flight of its giant, next-generation rocket, the first mission of the agency's moon-to-Mars Artemis program.

NASA scrapped its first attempt to launch Artemis I earlier this week, but a new launch is set for Saturday. How to watch the new moon mission.
