ESA European Space Agency

ESA, the European Space Agency is an intergovernmental organisation of 22 member states dedicated to the exploration of space. Established in 1975 and headquartered in Paris.

Participating countries: Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom. ESA is not an EU organisation.

ESA’s space flight programme includes human spaceflight (mainly through participation in the International Space Station program); the launch and operation of unmanned exploration missions to other planets and the Moon; Earth observation, science and telecommunication; designing launch vehicles; and maintaining a major spaceport, the Guiana Space Centre at Kourou (French Guiana), France. The main European launch vehicle Ariane 5 is operated through Arianespace with ESA sharing in the costs of launching and further developing this launch vehicle.

ESA Orion Service Module (SM)

  • European Service Module (ESM, SM) for the Orion spacecraft.
  • Developed, built and tested by ESA.
  • Operated by ESA and NASA.
  • Artemis program.

Provides electricity, propulsion, air and water. 15,461 kg. SM components:

  • Propulsion: 33 engines, 3 types. 4 tanks with 8000 litres of fuel.
  • Thermal control system: Heater and coolant (6 radiators outside the SM).
  • Consumables: Air and water (for 6 astronauts on a 20-day mission).
  • Solar Arrays: Turn on 2 axes to remain aligned with the Sun. 4 arrays.
  • Chassis structure: Holds everything together, absorbs vibrations, covered with Kevlar.
  • Avionics: Computers control all aspects of the SM: Propulsion, water, electronics and temperature.
  • Three abort scenario using the SM:
      1. Untargeted abort splashdown,
      2. Targeted abort splashdown,
      3. Ascent abort to orbit.
