The Space Launch System is the most powerful rocket ever developed by the US space agency, and is designed to send astronauts and their equipment back to the Moon after an absence of 50 years. The launch of Nasa’s new Artemis I Moon rocket is facing a potentially lengthy delay after a second postponement. Controllers tried and failed again on Saturday to get the Space Launch System vehicle to lift off. They were thwarted by a fuel leak. Is a fuel leak a very minor thing that could have been resolved during development and testing such delays ?
