Space Launch System

NASA says a faulty memory chip was the cause of a problem that forced technicians to swap out an engine control computer on the first Space Launch System rocket late last year, but the issue is not a constraint for an upcoming SLS fueling test or launch later this spring.

NASA says the first rollout of the Space Launch System moon rocket is planned for March ahead of a key fueling test on a seaside launch pad at Kennedy Space Center, a delay of several weeks to allow more time for work inside the Vehicle Assembly Building.

NASA will announce later this year the four astronauts who will slingshot around the far side of the moon on the Artemis lunar program’s first crew mission, currently scheduled for launch in 2024, the head of the agency’s human space exploration division recently said. The crew is expected to include three U.S. fliers and one Canadian astronaut.

With NASA’s powerful new 322-foot-tall moon rocket fully stacked at Kennedy Space Center, managers said Friday that Feb. 12 is the soonest the unpiloted Artemis 1 mission could blast off toward lunar orbit, a date that hinges on the outcome of a critical fueling test on the launch pad in January.

Technicians at NASA’s Kennedy Space Center worked overnight Wednesday to tighten 360 bolts connecting the Orion spacecraft for the Artemis 1 moon mission to the first Space Launch System heavy-lift rocket, hours after a crane hoisted the deep space capsule atop the booster inside the Vehicle Assembly Building.

Teams at NASA’s Kennedy Space Center moved the Orion spacecraft for the Artemis 1 moon mission into the Vehicle Assembly Building Tuesday for stacking on top of the Space Launch System.

Workers at NASA’s Kennedy Space Center have lifted the Orion Stage Adapter on top of the Space Launch System moon rocket, adding the structure housing 10 CubeSat rideshare payloads heading into deep space on the Artemis 1 mission. But three of the CubeSat missions missed their opportunity to fly on the first SLS mission.

The swing arms on the mobile launch tower for NASA’s Space Launch System released and retracted Sunday night inside the Vehicle Assembly Building at Kennedy Space Center, another key test on the march toward liftoff of the Artemis 1 moon mission.

The earliest NASA’s first Space Launch System moon rocket could roll out from the Vehicle Assembly Building to its seaside launch complex in Florida is in late November, officials told Spaceflight Now, leaving little time to conduct a critical fueling test, roll the rocket back into the VAB for final closeouts, then return to the pad for liftoff before the end of the year.
