NASA is moving forward with a plan to repair the fuel leak on its Artemis II moon rocket, which grounded the massive spacecraft after an overnight countdown was derailed due to a hydrogen leak. The agency plans to conduct the repairs on the pad before attempting another launch in March, when five launch days will be available between March 6 and March 11.
The leak, which is located between two umbilical plates where an 8-inch-wide hydrogen fuel line enters the base of the rocket, was detected during a fueling test Monday afternoon. Sensors recorded high concentrations of hydrogen in a cavity between the ground and rocket sides of the umbilical, forcing fueling to halt.
While the team was able to get the leak back under control by adjusting flow rates and temperature, it suddenly spiked again in the final six minutes of the practice countdown when the first stage hydrogen tank was being pressurized as it would be for launch. At that point, an automated control system stopped the countdown, and the launch team ended the test without accomplishing several major objectives.
NASA Administrator Jared Isaacman announced that the agency will forego attempting to launch the mission in February and instead delay the flight until March at the earliest. The Artemis II commander, Reid Wiseman, expressed his pride in the team's efforts despite the setback, stating that they "got a chance for the rocket to talk to us" and that it provided them with an opportunity to wring out the system.
The repair plan is expected to be completed on the pad, which is considered a safe and controlled environment. However, the leak was detected in a critical area of the rocket, and NASA officials acknowledged that it presented a significant challenge. The agency's chairman of the Mission Management Team, John Honeycutt, noted that the test gave them exactly what they needed β an opportunity to identify issues before asking their crew to fly.
The Artemis II mission is a historic flight around the moon, which will carry four astronauts on board. Although the launch has been delayed until March, it clears the way for a two-man, two-woman crew to blast off next week on a flight to the International Space Station.
