At 00:35 CEST today (18:35 local time on 1 April), NASA's Space Launch System rocket lifted off from the Kennedy Space Center in Florida, carrying four astronauts aboard the Orion spacecraft on Artemis II. At the heart of the mission is ESA's European Service Module, which powers, propels and sustains the Orion spacecraft and its crew on their journey around the Moon and safely back to Earth.
Over the next 10 days, NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, together with Canadian Space Agency astronaut Jeremy Hansen, will fly around the Moon and return safely to Earth, the first journey of its kind since Apollo 17 in 1972, over half a century ago.
Powering Orion on this historic voyage is our second European Service Module, which is responsible for life support for the astronauts, as well as power generation and propulsion. Its four solar arrays, each stretching seven metres, give electricity to the spacecraft, while its systems provide air, water, and a comfortable temperature for the astronauts. Thirty-three engines, including a powerful repurposed Space Shuttle engine, will guide Orion through deep space and perform critical manoeuvres on the lunar journey.
