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 […]

Relaxation, exercise, and biomedical studies were the key research objectives for the Expedition 74 crew on Thursday as NASA and its partners investigate ways to keep astronauts healthy on long-term missions. The International Space Station is also orbiting higher after the docked Progress 93 cargo craft fired its thrusters on Wednesday.

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 […]

Vein scans and pharmaceutical research topped the science schedule aboard the International Space Station on Wednesday. The Expedition 74 crew rounded out the day with Dragon cargo transfers, lab familiarization activities, and life support maintenance duties.

These scientists welcomed the new year from a ship at the tip of the Antarctic Peninsula. Their goal? Collect water samples comparable to oceans beyond Earth.

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 […]

The seven-member Expedition 74 crew is in its first full week together aboard the International Space Station following Saturday’s arrival of NASA’s SpaceX Crew-12 mission. The orbital septet is resuming its full complement of advanced space science and lab maintenance as the Crew-12 quartet familiarizes itself with station operations.

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 […]
