The problems with the fuel leak in NASA’s Space Launch System (SLS) have been solved, the American space agency reports. The test in which the moon rocket was completely filled with fuel was successful. NASA plans to make another launch attempt on September 27.By our tech editors
NASA made two launch attempts with the SLS rocket in late August and early September. Both times, the launch was canceled at the last minute due to issues. During the most recent launch attempt on September 3, an excessive fuel leak occurred.
The rocket is filled with liquid oxygen and liquid hydrogen. The spacecraft must be filled at extremely low temperatures. At low temperatures, the fuel tank shrinks 15 centimeters during filling. This creates tensions on, for example, the seams of the fuel tank, which can lead to small leaks.
Fuel leaks are normal, according to NASA, but must remain within safe limits. During the latest test, NASA adjusted the filling process by slightly increasing the temperature. The leakage that occurred this time remained within safe limits.

Rocket to take astronauts to the moon by 2024
The new launch attempt is now scheduled for September 27, with a backup on October 2. NASA still has to get approval from the authorities. NASA’s license for the previous launch attempts has expired.
The SLS rocket is also known as the moon rocket. The rocket is set to take astronauts back to the moon for the first time in 52 years in 2024. Ultimately, the rocket should also transport people to Mars.
