NASA performs necessary fueling test for Artemis

CAPE CANAVERAL, Flor. (NBC) - On September 21, NASA is conducting a fueling test of the Artemis Space Launch System.

Technicians are going through the process of loading supercold liquid hydrogen and liquid oxygen into the Space Launch System (SLS) Core.

This Wednesday's test comes after the planned September 3 test flight of Artemis I was delayed when a hydrogen leak was detected.

The Artemis I team replaced two seals to fix the leak that was associated with a "quick disconnect" mechanism that linked the SLS core stage with a fuel line from the mobile launch tower.

Following those repairs, NASA officials hope Wednesday's fueling test will put Artemis I back on track for a September 27 launch window, with a backup opportunity on October 2.

The ultimate goal of the Artemis Program is to return astronauts to the lunar surface.
