NASA will make a second launch attempt of Artemis I on Saturday

HUNTSVILLE, Ala. (WHNT) – NASA will make another attempt this weekend to launch the historic Artemis I mission after the first attempt was canceled on Monday.

NASA says the next launch attempt is scheduled for Saturday, September 3. The two-hour launch window is expected to open at 2:17 p.m. ET.

NASA executives weren’t clear on why they moved the second launch window from Friday to Saturday, but said they hoped they had learned enough to make necessary improvements before the next attempt.

“We agreed to change the loading procedure operationally and start our engine cooling earlier. We have also agreed to move our launch date to Saturday, September 3,” said Artemis Mission Manager Mike Sarafin.

The space agency canceled the first launch attempt on Monday after teams struggled to bring one of the four RS-25 engines on the bottom of the rocket’s core stage to the proper temperature range for liftoff. .

NASA officials say they believe there is a problem with the sensors that test the temperature of liquid hydrogen in the engines.

“These sensors are not piloted instruments. They were designed solely to be development flight instruments. And so we’re a bit concerned about one of those sensors,” says Space Launch System (SLS) program manager John Honeycutt.

So to circumvent these potential sensor issues, teams will now analyze data from Monday’s attempt to figure out the best way to calculate engine temperatures from ground sensors, to ensure the engines are within launch settings.

“We need to continue to analyze the data, we need to piece together the rationale for the flight anticipating that we won’t get better results on this three-point engine leak temperature sensor,” Honeycutt says.

NASA is moving the next launch window from Friday to Saturday, giving them just over 24 additional hours to review and reevaluate before their next attempt.

But the launch weather officer predicts disruptions.

“I am optimistic that we will have clear air to work with through Saturday afternoon, but again the likelihood of a weather violation at any time during the countdown still appears to remain high. “said Mark Berger of the US Space Force’s 45th Weather Service. Squadron.

This new window will open at 1:17 p.m. on Saturday and close 2 hours later.

If they can’t launch on Saturday, they’ll have another opportunity next Monday, before having to bring the SLS back to the vehicle assembly bay and wait for other launch windows in September.
