Artemis I Launch Highlights: NASA Artemis I Launch Called Off Due To Technical Issues With SLS Rocket Engine
The launch of Artemis I on Monday, August 29, was scrubbed due to a technical problem with one of the engines of the Space Launch System (SLS) rocket. As a result, the first leg of NASA’s Moon mission has been postponed.
NASA said in a mission update that the US space agency will keep everyone posted on the timing of the next launch attempt.
The launch director halted Monday's launch attempt of Artemis I at approximately 8:34 am EDT (6:04 pm IST).
A few hours before the launch attempt, NASA engineers were troubleshooting a conditioning issue with one of the RS-25 engines of the SLS, the world's most powerful rocket. Launch controllers increased the pressure on the core stage tanks to condition the engines, and to cause some of the cryogenic propellant to bleed to the engines. This is an important step because it ensures the engines can reach the proper temperature range to get started.
However, NASA teams observed an issue with the bleeding of engine number 3. As a result, the mission was scrubbed.
