NASA is targeting approximately 9 a.m. EST, Wednesday, Feb. 25, to begin rolling the SLS (Space Launch System) rocket and Orion spacecraft for Artemis II off the launch pad and back to the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida. Teams will continue to monitor winds and temperatures in advance […]
Due to weather, NASA now is targeting early Wednesday, Feb. 25, to roll the SLS (Space Launch System) rocket and Orion spacecraft for Artemis II off the launch pad and back to the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida. Cold temperatures and high winds are expected Tuesday, and rolling […]
Weather pending, NASA will roll the SLS (Space Launch System) rocket and Orion spacecraft for Artemis II off the launch pad at the agency’s Kennedy Space Center in Florida as soon as Tuesday, Feb. 24. Engineers are continuing to prepare for the move after encountering an issue with the flow of helium to the rocket’s […]
Editor’s note: NASA has updated an earlier version of this blog to provide additional details. NASA is taking steps to potentially roll back the Artemis II rocket and Orion spacecraft to the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida after overnight Feb. 21 observing interrupted flow of helium to the […]
NASA is targeting no earlier than Friday, March 6, for the launch of Artemis II, pending completion of required work at the launch pad, analysis of test data, and the outcome of a Flight Readiness Review in the coming days. The four astronauts set to fly around the Moon during the test flight entered quarantine […]
NASA successfully fueled its SLS (Space Launch System) rocket and demonstrated the launch countdown for Artemis II on Thursday during a wet dress rehearsal at the agency’s Kennedy Space Center in Florida. Engineers loaded more than 700,000 gallons of liquid propellant into the rocket, sent a closeout crew to the launch pad to demonstrate closing the Orion spacecraft’s hatches, and completed two runs of terminal count — the final phase of the launch countdown. The Artemis II crew also observed part of […]
Live updates for the Artemis II wet dress rehearsal will be published on this page. Live views of the launch pad and test are available online. All times are Eastern. 10:18 p.m. The Artemis II wet dress rehearsal ended today at 10:16 p.m., concluding as planned at T-29 seconds in the countdown. NASA will hold […]
NASA continues to press ahead through the Artemis II wet dress rehearsal countdown – a fueling test of the SLS (Space Launch System) rocket. Early this morning, at approximately 3 a.m. EST, teams powered up the rocket’s core stage, which will be loaded with more than 700,000 gallons of liquid oxygen and liquid hydrogen during […]
The countdown for the Artemis II wet dress rehearsal is underway at NASA’s Kennedy Space Center in Florida. The countdown clock began at 6:50 p.m. EST Tuesday, or L-49 hours, 40 minutes before the opening of a simulated launch window at 8:30 p.m., Thursday, Feb. 19. The test is expected to go until approximately 12:30 […]
NASA is targeting Thursday, Feb. 19, as the tanking day for the second wet dress rehearsal ahead of the agency’s Artemis II test flight. Over the weekend, teams replaced a filter in ground support equipment that was suspected of reducing the flow of liquid hydrogen during a Feb. 12 partial fueling test. The test provided […]
