At 1 p.m. EDT on Monday, Aug. 29, NASA leaders gave an update on the launch of the Artemis I flight test. Following tanking operations, engineers were troubleshooting an issue conditioning one of the RS-25 engines (engine 3) on the bottom of the rocket's core stage. All engines must reach a proper temperature range before they can be started. Teams are poring through the data and will set a new launch date and time. Artemis I is the first integrated flight test of the Space Launch System (SLS) and Orion spacecraft that will return humanity to the Moon. As NASA’s most powerful rocket ever built, SLS will launch the uncrewed Orion spacecraft on a six-to-eight-week mission around the Moon and back to Earth. Orion will travel 280,000 miles (450,000 km) from Earth and 40,000 miles (64,000 km) beyond the far side of the Moon, carrying science and technology payloads to expand our understanding of lunar science, technology developments, and deep space radiation.
