NASA and ESA will brief media at 17:30 CET on Wednesday, 16 January, on the details for ESA to provide a service module for the first Orion spacecraft mission in 2017. European media are invited to watch the event and can ask questions.

Orion will be the most advanced spacecraft ever designed and carry astronauts farther into space than ever before. ESA’s service module will be based on the Automated Transfer Vehicle (ATV). Sitting directly below Orion’s crew capsule, it will provide propulsion, power, thermal control, as well as supplying water and atmosphere for the astronauts in the habitable module.
