NASA conducted a news conference on Tuesday, Feb. 3, to discuss initial findings from the recently completed Artemis II wet dress rehearsal test. Participants included:
Biomedical research to keep crews healthy and CubeSat deployments for educational research topped the science schedule aboard the International Space Station on Tuesday. The Expedition 74 crew also focused on cargo swaps and life support maintenance throughout the day.
The Sun emitted a strong solar flare, peaking at 9:08 a.m. ET on Feb. 3. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft […]
NASA concluded a wet dress rehearsal for the agency’s Artemis II test flight early Tuesday morning, successfully loading cryogenic propellant into the SLS (Space Launch System) tanks, sending a team out to the launch pad to closeout Orion, and safely draining the rocket. The wet dress rehearsal was a prelaunch test to fuel the rocket, designed to […]
The Artemis II wet dress rehearsal countdown was terminated at the T-5:15 minute mark due to a liquid hydrogen leak at the interface of the tail service mast umbilical, which had experienced high concentrations of liquid hydrogen earlier in the countdown, as well. The launch control team is working to ensure the SLS (Space Launch […]
NASA teams officially entered the final 10 minutes of today’s Artemis II wet dress rehearsal countdown known as terminal count after Charlie Blackwell-Thompson, NASA’s Artemis launch director, gave the “go” to proceed. During terminal count, automated systems take control of countdown operations, final checks of flight computers, engine bleed systems, and ground support equipment occur, and the rocket […]
NASA’s Artemis II closeout crew has completed its critical tasks and departed NASA Kennedy’s Launch Complex 39B during the Artemis II wet dress rehearsal. The departure of the closeout crew marks the transition to the final countdown phase, ensuring the launch pad is clear and safe for simulated liftoff procedures. Although the Artemis II astronauts did not […]
NASA teams completed closing the launch abort system hatch during the Artemis II wet dress rehearsal, simulating final launch day procedures. The launch abort system hatch provides access to the Orion crew module through the outer aeroshell of the launch abort system and must be securely sealed to ensure crew safety during ascent. Closing the launch abort […]
The Artemis II wet dress rehearsal entered the T-10 minute hold in the simulated countdown at 8:50 p.m. EST. Though it had been counting down to the opening of a simulated launch window at 9 p.m. EST Monday, Feb. 2, the test will proceed as teams continue to work through countdown milestones. The closeout crew […]
