The Space launch system

It takes a lot of power to send 26 tonnes worth of cargo to the Moon

1 Four RS-25 engines

NASA claims they’re the most efficient engines ever built.

2 Solid rocket boosters

Each one is the height of a 17-storey building.

3 Core stage

Contains almost 3 million litres of propellant, enough to power the engines for eight minutes.

4 Orion stage adapter

Where small satellites are stored ahead of delivery to deep space.

5 Orion spacecraft

The living quarters for the astronauts that will fly on future Artemis missions.

6 Interim cryogenic propulsion stage

The juice needed for the final push towards the Moon once Artemis 1 leaves Earth orbit.
