(©NASA/Eric Bordelon) Will the Orion capsule from the Artemis I mission ever leave? NASA’s mega rocket was scheduled to lift off on Monday, August 29, 2022 at 2:33 pm French time. Ultimately, the launch was canceled due to a leak in the launch station’s No. 3 engine. The postponement date fell this Saturday, September 3, 2022, at 20:17 French time. A leak has been detected, but a new problem has come to interrupt the party. The teams found a leak of liquid hydrogen while loading propellant into the center stage of the rocket’s launch system. Multiple troubleshooting efforts to address the area of ​​the leak by reinstalling a seal on the quick disconnect where liquid hydrogen is introduced into the rocket have not resolved the problem. NASA’s Artemis I mission will not launch this Saturday. “Ultra-sophisticated plumbing” “Reminds everyone how complex space is. It’s the right decision,” commented Josef Aschbacher, director general of the European Space Agency. See the tweet Videos: currently at ActuMais, so we have the right to ask ourselves how it is possible that in 1969, engineers with the knowledge of the time managed to successfully take off to the moon, and that in 2022, 53 years later, we can no longer do so. they are no less good than those of 1969,” says Gilles Dawidowicz, vice-president of the French astronomical society and president of the planetology commission, contacted by actu.fr. “But, in fact, they have to play with quite old components.” He explains that we thought it would be a good idea to reuse engines that have already flown. “We thought it would cost less, but sometimes making new with old doesn’t work,” he notes. Beyond that, a space launch station like the one that had of launching Orion is “miles of pipes. Ultra-sophisticated plumbing, in which liters of hydrogen and liquid oxygen roam, at -217°C and -181°C respectively. phenomena of expansion and retraction of structures. This can damage the machinery, and compromise the entire operation”, explains the president of the planetology commission. Considering the billions of euros that such a launch costs, we should not miss it, especially since of the 22 people who lost their lives during a space journey, only three were beyond the limits of the atmosphere . Most accidents occur during takeoff. So we understand that NASA does not want to take any risks for the launch. When is the new test? At the moment it is difficult to predict. As experts from the National Center for Space Studies explained during the animated live stream during the first launch, “the stars move in the sky, and the meeting can only be done when the objects [stellaires] are correctly positioned. At the time of writing, NASA has not communicated a postponement date. Was this article helpful to you? Note that you can follow Actu in the My Actu space.
