The US just returned to the Moon after more than 50 years. How big a deal is it, really?

Intuitive Machines, CC BY-NC-ND David Flannery, Queensland University of TechnologyIn the few short years since the COVID pandemic changed our world, China, Japan and India have all successfully landed on the Moon. Many more robotic missions have flown past the Moon, entered lunar orbit, or crashed into it in the past five years. This includes spacecraft developed by South Korea, the United Arab Emirates, and an Israeli not-for-profit organisation. Late last week, the American company Intuitive Machines, in collaboration with NASA, celebrated “America’s return to the Moon” with a successful landing of its Odysseus spacecraft. Recent Chinese-built sample return missions are far more complex than this project. And didn’t NASA ferry a dozen humans to the Moon back when microwaves were cutting-edge technology? So what is different about this mission developed by a US company? Back to the Moon The recent Odysseus landing stands out for two reasons. For starters, this is the first time a US-built spacecraft has landed – not crashed – on the Moon for over 50 years. Secondly, and far more significantly, this is the first time a private company has pulled off a successful delivery of cargo to the Moon’s surface. NASA has lately focused on destinations beyond the Earth–Moon system, including Mars. But with its Commercial Lunar...

NASA scrubs launch of giant Moon rocket, may try again Friday

NASA scrubs launch of giant Moon rocket, may try again FridayNASA has scrubbed a test flight of its powerful new rocket, in a setback to its plan to send humans back to the Moon and eventually to Mars, but may shoot for another launch attempt on Friday. "We don't launch until it's right," NASA administrator Bill Nelson said after an engine issue forced a cancellation of Monday's flight from the Kennedy Space Center in Florida. "This is a very complicated machine," Nelson said. "You don't want to light the candle until it's ready to go." The goal of the mission, baptized Artemis 1 after the twin sister of Apollo, is to test the 322-foot (98-meter) Space Launch System (SLS) rocket and Orion crew capsule that sits on top. The mission is uncrewed -- mannequins equipped with sensors are standing in for astronauts and will record acceleration, vibration and radiation levels. Mike Sarafin, mission manager of Artemis 1, said the space agency is hoping to make another launch attempt later this week. "Friday is definitely in play," Sarafin said. NASA would have a better idea of whether a Friday launch is feasible after a meeting on Tuesday of the management team, he said. "We just need a little bit of time to look at the data," Sarafin said. Next Monday, September 5, is an alternative launch date. Blastoff had been planned for 8:33 am (1233...
