NASA's moon rocket setback delays Artemis II mission into spring
Helium flow interruption to rocket's upper stage caused the latest problem

This is the second major issue following previous hydrogen fuel leaks
Artemis program aims to return humans to the moon after a 50+ year gap
📖 Full Retelling
NASA announced Saturday that its new moon rocket has suffered another setback at Kennedy Space Center, with interrupted helium flow to the rocket's upper stage almost certainly delaying the Artemis II mission with four astronauts into spring, as revealed by Administrator Jared Isaacman. The space agency revealed the latest problem just one day after targeting March 6 for the Artemis II mission, humanity's first flight to the moon in more than half a century. Overnight, the flow of helium to the rocket's upper stage was interrupted, officials said, noting that solid helium flow is essential for purging the engines and pressurizing the fuel tanks. This helium issue has nothing to do with the hydrogen fuel leaks that marred a countdown dress rehearsal earlier this month and forced a repeat test. NASA Administrator Jared Isaacman said a bad filter, valve or connection plate could be to blame for the stalled helium flow, and regardless of the cause, the only way to access the area and fix the problem is in the Vehicle Assembly Building at Kennedy Space Center. 'We will begin preparations for rollback, and this will take the March launch window out of consideration,' Isaacman said via X, noting that NASA's next opportunities would be at the beginning or end of April. The four astronauts had already entered their two-week quarantine Friday night, mandatory for avoiding germs, as the agency had been preparing for the March launch following a successful second fueling test that revealed minimal hydrogen leaks.

Artemis II is a planned lunar spaceflight mission under the Artemis program, led by NASA. It is intended to be the second flight of the Space Launch System (SLS), and the first crewed mission of the Orion spacecraft. It is the first crewed mission around the Moon, and beyond low Earth orbit, since A...

The helium flow problem delays NASA's Artemis II mission, pushing the first crewed lunar flight in over 50 years into April. This setback affects the program's timeline, budget and international partnerships.
Context & Background
Artemis II was targeted for March 6 launch
Helium flow is needed to purge engines and pressurize fuel tanks
Previous hydrogen fuel leaks already delayed the mission
The rocket will be returned to the Vehicle Assembly Building for repairs
Next launch windows are early or late April
What Happens Next
NASA will complete repairs to the helium system in the Vehicle Assembly Building and conduct additional tests before attempting a launch in early or late April. If successful, the Artemis II mission will proceed, but further delays remain possible if issues persist.
Frequently Asked Questions
What caused the helium flow issue?
A likely faulty filter, valve or connection plate stopped the helium supply to the upper stage.
Will the launch be moved to a different launch pad?
NASA plans to repair the rocket in the Vehicle Assembly Building, not at the launch pad.
How will this affect the overall Artemis program?
The delay pushes the first crewed lunar flight into April and may impact subsequent mission schedules and budgets.

NASA's new moon rocket suffered another setback Saturday, almost certain to bump astronauts' first lunar trip in decades into spring. The space agency revealed the latest problem just one day after targeting March 6 for the Artemis II mission, humanity's first flight to the moon in more than half a century. Overnight, the flow of helium to the rocket's upper stage was interrupted, officials said. Solid helium flow is essential for purging the engines and pressurizing the fuel tanks. This helium issue has nothing to do with the hydrogen fuel leaks that marred a countdown dress rehearsal of the Space Launch System rocket earlier this month and forced a repeat test. NASA Administrator Jared Isaacman said a bad filter, valve or connection plate could be to blame for the stalled helium flow. Regardless of the cause, he noted, the only way to access the area and fix the problem is in the Vehicle Assembly Building at Kennedy Space Center. "We will begin preparations for rollback, and this will take the March launch window out of consideration," Isaacman said via X. NASA's next opportunities would be at the beginning or end of April. Earlier in the morning, NASA said it was preparing to return the 322-foot (98-meter) rocket to its hangar for repairs, while raising the possibility of the work being done at the pad. "I understand people are disappointed by this development," Isaacman said. "That disappointment is felt most by the team at NASA, who have been working tirelessly to prepare for this great endeavor." Hydrogen fuel leaks had already delayed the Artemis II lunar fly-around by a month. A second fueling test on Thursday revealed hardly any leaks, giving managers the confidence to aim for a March liftoff. The four astronauts went into their two-week quarantine Friday night, mandatory for avoiding germs. The interrupted helium flow is confined to the SLS rocket's interim cryogenic propulsion stage. This upper stage is essential for placing the Orion crew capsule into th...
