Nasa Artemis 1 launch

The new Space Launch System's initial launch will be Artemis 1. According to NASA, this vehicle is a "heavy lift" vehicle.

On Saturday, September 3, the launch countdown will continue at the commencement of a planned 2.5-hour built-in hold, which will start at 4:37 a.m.

The initial launch attempt was aborted on August 29 because launch controllers were unable to cool down the four RS-25 engines, with one engine running on higher temperature than the others.

Artemis I is an autonomous mission to the Moon that will be the first in a succession of increasingly complicated missions that will eventually return humans to Earth's lone satellite.
