Following the Artemis I pre-launch briefing, meteorologists with the U.S. Space Force Space Launch Delta 45 predict a 60% chance of favorable weather conditions at the beginning of the two-hour launch window that opens at 2:17 p.m. EDT Sept 3, increasing to an 80% chance of favorable weather conditions toward the later part of the …
The Artemis I mission management team met this afternoon to review the status of the operations and have given a “go” for a Sept. 3 launch attempt of the Space Launch System rocket and Orion spacecraft. Since the previous launch attempt on Monday, Aug. 29, teams have updated procedures, practiced operations and refined timelines. Over …
Meteorologists with the U.S. Space Force Space Launch Delta 45 predict a 60% chance of favorable weather conditions for an Artemis I launch attempt during a two-hour window that opens at 2:17 p.m. EDT Saturday, Sept. 3. While rain showers are expected in the area, they are predicted to be sporadic during the launch window. …
NASA will target Saturday, Sept. 3 at 2:17 p.m. EDT, the beginning of a two-hour window, for the launch of Artemis I, the first integrated test of NASA’s Orion spacecraft, Space Launch System (SLS) rocket, and the ground systems at the agency’s Kennedy Space Center in Florida. Mission managers met Tuesday to discuss data and …
Engineers are evaluating data gathered during the Artemis I launch attempt Monday, Aug. 29, when teams could not get the rocket’s engines to the proper temperature range required to start the engines at liftoff, and ran out of time in the two-hour launch window to continue. The mission management team will convene Tuesday afternoon to discuss …
The launch director halted today’s Artemis I launch attempt at approximately 8:34 a.m. EDT. The Space Launch System rocket and Orion spacecraft remain in a safe and stable configuration. Launch controllers were continuing to evaluate why a bleed test to get the RS-25 engines on the bottom of the core stage to the proper temperature …
Teams are in a hold in the countdown at T-40 minutes while engineers evaluate why the bleed test to condition the engines was not successful. Engineers are looking at options to gather as much data as possible. The Artemis I rocket and spacecraft are in a stable, safe condition.
While liquid oxygen loading into the interim cryogenic propulsion stage continues and core stage tanks continue to be replenished with propellants, engineers are troubleshooting an issue conditioning one of the RS-25 engines (engine 3) on the bottom of the core stage. Launch controllers condition the engines by increasing pressure on the core stage tanks to …
The Space Launch System’s core stage liquid oxygen (LOX) and liquid hydrogen (LH2) tanks are fully fueled and both are being replenished. During replenish, the propellant that naturally boils off is being replaced to ensure the tanks are at full capacity for launch. A “go” has been given for liquid oxygen loading into the interim …
As teams continue to fuel the Space Launch System (SLS) rocket’s core stage with liquid oxygen (LOX) and liquid hydrogen (LH2), teams have been given a go to begin propellant loading operations for the rocket’s interim cryogenic propulsion stage (ICPS). The ICPS is the upper stage of the rocket responsible for giving the Orion spacecraft the …
