NASA will be rolling back the Artemis II SLS rocket and Orion spacecraft to the Vehicle Assembly Building (VAB) at the Kennedy Space Center in Florida observing interrupted flow of helium in the rocket’s interim cryogenic propulsion stage (ICPS). Weather pending, the roll back will take place on Tuesday, February 24. NASA is investigating potential faults, but accessing and remediating any of these issues can only be performed in the VAB. This removes the March launch opportunities from consideration.
NASA conducted this week a second countdown rehearsal and tanking test of the SLS rocket, called a wet dress rehearsal, where they assessed the readiness of all systems, including flight hardware, infrastructure, as well as launch, flight, and recovery teams. The mission management team was satisfied with the overall results and determined that they would try to launch on March 6, 2026 pending completion of required work at the launch pad, analysis of test data, and the outcome of a Flight Readiness Review (FRR) that NASA will hold at the end of next week.
Canadian Space Agency astronaut Jenni Gibbons explains her role as a capsule communicator, or capcom, for the Artemis II mission. The first Canadian certified in this role, she describes how capcoms are the primary link between Mission Control and the spacecraft, working in shifts to provide the crew with critical guidance during their mission to the Moon.
