Airbus to build three more moon mission modules


The European Space Agency has contracted Airbus Defence and Space to build three more European service modules (ESM) to be used as part of the Artemis moon landing program. The new contract adds to the three ESMs already in production. All three of the new modules will propel astronauts to the moon.


The ESM provides power, propulsion and life support to Nasa’s Orion crew capsule. Each ESM is 4 metres in diameter and height. Its four solar arrays span 19 metres when unfurled and can generate enough energy to power two households. The ESM’s 8.6 tonnes of fuel powers its main engine and 32 smaller thrusters.

首个ESM在NASA位于佛罗里达州的肯尼迪航天中心,为定于今年晚些时候进行的无人Artemis I测试飞行做准备。第二个ESM将载着宇航员绕月球飞行并返回。第三个ESM将搭载宇航员,他们将在2024年之后的某个时候降落到火星表面。

The first ESM is at Nasa’s Kennedy Space Center in Florida being prepared for the uncrewed Artemis I test flight scheduled later this year. The second ESM will fly astronauts around the moon and back. The third ESM will carry the astronauts who will descend to the surface, sometime after 2024.
