NASA will try to launch the Artemis I mission again, this time on Saturday, September 3, starting at 21:17 (Romanian time). Artemis I will be the first integrated test of the Orion spacecraft and the Space Launch System (SLS) rocket, and the event will take place from the Kennedy Space Center in Florida.
Artemis I mission managers met to discuss data from the aborted launch on Monday, Aug. 29, and then developed a plan to resolve problems that arose on the day of the original launch.
During the first test, the teams were unable to cool the four RS-25 engines to the temperature of about minus 215 degrees Celsius, and engine 3 had higher temperatures than the rest of the engines.
The teams also noticed a leak of hydrogen.
What will NASA teams do in the coming days?
In the coming days, NASA teams will modify and test fuel loading procedures to perform a procedure similar to what was successfully accomplished during another test, known as the Green Run, at NASA’s Stennis Space Center in Mississippi.
The updated procedures will involve cooling the engines approximately 30 – 45 minutes earlier as part of the countdown during the liquid hydrogen filling phase.
What will the weather be like on launch day?
Researchers are also configuring platforms at Launch Pad 39B to allow engineers to access and perform analysis when appropriate, according to GODMOTHER.
Meteorologists at US Space Force Space Launch Delta 45 have announced favorable weather for Saturday, September 3. Although rain is expected, it will be sporadic during the launch interval announced by the US space agency.
