NASA is trying to launch in September after addressing moon rocket leaks.
NASA is repairing faulty seals on its moon rocket at the launch pad in anticipation of flying it on its maiden test flight by the end of this month, according to CAPE CANAVERAL, Fla.
In order to make sure all hydrogen fuel leaks are sealed, managers declared on Thursday that they will do another test following the repairs.
NASA may attempt to launch the 322-foot rocket once again in late September if the test launch goes well and the Space Force grants a flight safety waiver.
If this happens, the rocket will need further development and won't launch until at least October.
Last week, several hydrogen fuel leaks and other issues prevented back-to-back launch attempts.
The Space Launch System rocket, the most potent NASA has ever produced, is carrying a crew capsule with three test subjects inside.
