Engineers bumped into issues repressurizing the Artemis II moon rocket’s higher stage helium tanks in a single day Friday, an issue that may require rolling the massive rocket off the launch pad and again to its processing hangar for troubleshooting. The work will push the already delayed mission from March into early April, NASA officers stated Saturday.
Pressurized helium is used to push propellants to rocket engines for ignition and to purge varied gasoline strains to clear them out earlier than propellants stream. It isn’t but identified what is likely to be stopping helium from flowing again into the SLS rocket’s higher stage following a profitable countdown rehearsal take a look at that ended Thursday.
“Whatever the potential fault, accessing and remediating any of those points can solely be carried out within the VAB (Car Meeting Constructing),” NASA Administrator Jared Isaacman stated in a submit on the social media platform X. “We’ll start preparations for rollback, and it will take the March launch window out of consideration.”
A NASA spokesperson confirmed to CBS Information {that a} March launch is not potential and the groups have switched to rollback preparations.
“Groups are reviewing potential causes of the difficulty, together with within the interface between floor and rocket strains used to route helium, in a valve within the higher stage, and with a filter between the bottom and rocket,” NASA stated in an announcement on Saturday.
The Artemis II mission goals to ship 4 astronauts — Reid Wiseman, Victor Glover, Christina Koch and Canadian astronaut Jeremy Hansen — on a flight across the far aspect of the moon and again to completely take a look at the company’s Orion deep house capsule to assist clear the way in which for a lunar touchdown mission, Artemis III, in 2028.

Due to the ever-changing positions of the Earth and moon, and related modifications in lighting and different components, solely a handful of launch alternatives can be found every month that meet the Artemis II mission necessities. The present launch interval ends on March 11. The accessible launch dates subsequent month are April 1, 3, 4, 5 and 6.
Wiseman, Glover, Koch and Hansen initially hoped to launch early this month, however hydrogen leaks detected throughout an preliminary “moist costume countdown” rehearsal finally pushed the flight to March.
NASA accomplished a second fueling take a look at and countdown on Thursday, loading the House Launch System rocket with greater than 750,000 gallons of liquid oxygen and hydrogen gasoline whereas working by way of the steps that might be wanted to really launch the massive rocket on the long-awaited mission.
The take a look at went properly; there have been no gasoline leaks like those that derailed plans for a launch earlier this month. Managers stated Friday the group would press forward for a launch try on March 6 to ship Wiseman and his crewmates to the moon.
Hoping for the very best, the astronauts went into pre-flight medical quarantine on the Johnson House Heart on Friday night and deliberate to fly to the Kennedy House Heart on March 1 to arrange for launch. They’ll now go away quarantine to await developments.
“I perceive persons are dissatisfied by this growth,” Isaacman stated. “That disappointment is felt most by the group at NASA, who’ve been working tirelessly to arrange for this nice endeavor.”
Throughout NASA’s Apollo program, 24 astronauts flew to the moon from 1968 by way of 1972. The brand new Artemis program has accomplished just one flight up to now, a lunar-orbiting mission and not using a crew in 2022.
“I’ll say once more, the President created Artemis as a program that may far surpass what America achieved throughout Apollo. We’ll return within the years forward, we’ll construct a Moon base, and undertake what must be steady missions to and from the lunar atmosphere,” Issacman stated. “The place we start with this structure and flight price just isn’t the place it’ll finish.”
