A host of biomedical studies filled the Expedition 67 crew’s day as NASA and its international partners continue exploring how living in space long-term affects the human body. The residents aboard the International Space Station also set up a 3-D hologram device and tested a new robotic arm. The orbiting lab’s four astronauts took turns …
The Artemis I wet dress rehearsal ended today at 7:37 p.m. EDT at T-29 seconds in the countdown. Today’s test marked the first time the team fully loaded all the Space Launch System rocket’s propellant tanks and proceeded into the terminal launch countdown, when many critical activities occur in rapid succession. During propellant loading operations …
The launch control team is filling the Space Launch System’s interim cryogenic propulsion stage (ICPS) with liquid hydrogen (LH2) followed by liquid oxygen (LOX) loading. The core stage LH2 and LOX tanks, meanwhile, are being replenished as some of the supercool propellant boils off, meaning the propellant tank will be full through the rest of …
On Monday at 10:20 a.m. Central time, Northrop Grumman’s Cygnus NG CRS-17 engine was scheduled to fire for 5 minutes, 1 second to test the cargo craft’s ability to reboost the International Space Station in the future. The engine firing was aborted after five seconds. Cygnus’ Mission Director at Dulles, Virginia reported that the cause …
The launch control team has begun chill down operations and resumed the countdown clock ahead of flowing super cold liquid oxygen (LOX) into the core stage tank. The T-0 time for today’s test is now 4:38 p.m. EDT for the first of the two terminal count runs for the wet dress rehearsal. The process for …
The launch director gave the “go” to start tanking operations. The countdown will resume at 9:20 a.m. EDT at T-6 hours, 40 minutes. Tanking begins with chilling down, or cooling, the liquid oxygen propellant lines for the core stage. In sequential fashion, liquid oxygen (LOX) and liquid hydrogen (LH2) will flow into the rocket’s core stage …
The mission management team chair has given a “go” to proceed with tanking the Space Launch System rocket for the Artemis I wet dress rehearsal test. As the countdown continues, the launch director will be responsible for giving the “go” to officially begin the tanking process. Meteorologists with Space Launch Delta 45 said that weather remains favorable for …
The mission management team for Artemis I met this afternoon to review the status of operations and continues to press ahead toward terminal countdown for the wet dress rehearsal test. Meteorologists with the U.S. Space Force Space Launch Delta 45 currently predict favorable weather conditions for tanking operations on Monday, June 20. Weather constraints stipulate …
The launch team is making its way through countdown operations and wet dress rehearsal activities remain on track. The mission management team will meet this afternoon to review the status of operations. Overnight, engineers powered up the Orion spacecraft and the Space Launch System’s core stage. Teams also configured several systems on the ground, …
At approximately 5 p.m. EDT today, the launch team arrived at their stations inside the Launch Control Center at NASA’s Kennedy Space Center in Florida to begin the wet dress rehearsal test for NASA’s Artemis I mission. The countdown began 30 minutes later at 5:30 p.m. or L-45 hours, 10 minutes before the initial target …
