NASA delays rocket launch to moon for second time

NASA named the program after the twin sister of Apollo, the moon goddess in Greek mythology.The reason for the second cancellation in six days was a liquid hydrogen propellant leak. The Project Artemis I unmanned test mission is the first step towards returning humans to the Moon since 1972. For the second time in six days, NASA postponed this Saturday (03/09) the launch of the Space Launch System (SLS) rocket. , of the Artemis I project in Cape Caneveral, Florida. The unmanned test mission is the first step towards returning humans to the Moon since the Apollo 17 mission in 1972. The launch of the 98-meter-tall SLS and its Orion capsule has been further delayed after repeated attempts space technicians. repair a leak of supercooled liquid hydrogen propellant on the third stage of the vehicle. Operations were canceled approximately three hours before the two-hour launch window, scheduled to open at 3:17 p.m. (Brasilia time). A new attempt should not take place before the end of September. Last Monday, the first launch attempt was thwarted by technical difficulties, including a leaky fuel line, a faulty temperature sensor and some cracks in the insulating foam. NASA said these issues have been resolved. What is the Artemis program? The launch will be the first in a series of six scheduled missions to the Moon through 2028. With no astronauts aboard the Orion spacecraft, Artemis I will primarily be a safety test for future manned travel. Initiated in 2017 and formed by NASA, the European Space Agency (ESA) and space agencies from other countries, the Artemis program is part of efforts to revitalize space programs. “We want to extend the reach of human beings in space. The Moon is our closest neighbour. Despite the research potential, Artemis aims above all to conquer our first anchor in space”, says Jürgen Schlutz, aerospace engineer at ESA. NASA named the program after the twin sister of Apollo, the moon goddess in Greek mythology. Orion is a partially reusable spacecraft, equipped with solar panels and an automatic docking system, and equipped with primary and secondary propulsion engines. ESA, along with other European companies such as AirBus, has played a central role in developing the technology for the spacecraft, which can accommodate up to six crew members. On its maiden voyage, Orion will carry three mannequins, fitted with sensors to measure radiation, acceleration and vibration. To Mars Ultimately, Artemis’ objective is a manned mission to Mars. Schlutz says the Moon is a milestone, as it will be like a kind of outpost for these missions. The forecast is that by the end of this decade, the first lunar landing platform will be completed. The Chinese National Space Administration and the Russian space agency Roscosmos also plan to build their own bases on the Moon by the early 2030s. On Artemis, the lunar base would support missions to Mars and be used as outpost to improve technologies and living conditions. The trip to her would take less than a week. “The environment on the Moon is inhospitable. Our biggest challenge is to protect astronauts from radiation. We want to build housing modules with exterior regolith bricks.” [poeira lunar] to block radiation,” says ESA materials scientist Aiden Cowley. Resource management, radiation protection and energy harvesting systems will be tested on the Moon before being taken to Mars, which takes six months. to travel (AFP, Reuters)
