The Area Launch System, with the Orion crew capsule, stands at launch advanced 39B through the Moist Gown Rehearsal, a full-scale countdown and propellant load, for the Artemis II mission to the Moon at Kennedy Area Heart in Cape Canaveral, Florida, on Feb. 2, 2026.

Within the newest setback to return astronauts to the moon, NASA delayed the extremely anticipated flight but once more after a brand new drawback cropped up with the rocket Saturday.
April is now the earliest that the 4 Artemis II astronauts might fly to the moon.
NASA revealed the newest drawback simply at some point after concentrating on March 6 for Artemis II, humanity’s first flight to the moon in additional than half a century. In a single day, the stream of helium to the rocket’s higher stage was interrupted, officers stated. Stable helium stream is important for purging the engines and pressurizing the gas tanks
This helium concern has nothing to do with the hydrogen gas leaks that marred a countdown gown rehearsal of the Area Launch System rocket earlier this month and compelled a repeat check.
NASA Administrator Jared Isaacman stated a foul filter, valve or connection plate may very well be responsible for the stalled helium stream. Whatever the trigger, he stated, the one approach to entry the realm and repair the issue is to return the 322-foot (98-meter) rocket to its hangar for repairs.
“We are going to start preparations for rollback, and this may take the March launch window out of consideration,” Isaacman stated by way of X. NASA’s subsequent alternatives can be firstly or finish of April.
“I perceive individuals are disillusioned by this improvement,” he added. “That disappointment is felt most by the crew at NASA, who’ve been working tirelessly to arrange for this nice endeavor.”
Earlier within the day, NASA stated it was getting ready to maneuver the rocket again to the Car Meeting Constructing at Kennedy Area Heart whereas elevating the opportunity of the work being accomplished on the pad.
The state of affairs is dynamic, stated spokeswoman Cheryl Warner. Whether or not the fixes are on the pad or within the hangar, the rollback preparations alone rule out any probability of creating a March launch, she stated.
Hydrogen gas leaks had already delayed the Artemis II lunar fly-around by a month. A second fueling check on Thursday revealed hardly any leaks, giving managers the boldness to goal for a March liftoff. The 4 astronauts went into their two-week quarantine Friday night, necessary for avoiding germs.
Every thing labored superb with the rocket’s helium system throughout each gown rehearsals, Isaacman stated. The “surprising improvement” cropped up later in routine testing that saved engineers up all evening assessing the state of affairs.
The interrupted helium stream is confined to the SLS rocket’s interim cryogenic propulsion stage. This higher stage is important for putting the Orion crew capsule into the correct high-altitude orbit round Earth for checkout, following liftoff. After that, it is presupposed to separate from Orion and function a goal for the astronauts contained in the capsule, permitting them to observe docking methods for future moon missions.
Throughout NASA’s Apollo program, 24 astronauts flew to the moon from 1968 by 1972. The brand new Artemis program has accomplished just one flight up to now, a lunar-orbiting mission with no crew in 2022. That first check flight was additionally affected by hydrogen gas leaks earlier than blasting off, in addition to a helium concern much like the one which arose Saturday. The primary moon touchdown with a crew below Artemis continues to be at the least just a few years away.
