Animation of the flight of Orion, the space vehicle for the Artemis mission to the moon

The European Space Agency has released a video of the first uncrewed mission of NASA’s Orion spacecraft, which provided it with a service module. This video focuses on the role of Orion-equipped service modules. This is our opportunity to tell you more about this module that is critical to the operation of the Orion aircraft.American astronauts drink and breathe Made in Europe !

European service modules areESA to space vehicle Orion. Within this framework, ESA is providing €450 million in funding for the development and production of the first service modules.This amount corresponds to which ESA must pay to NASA Period 2018-2020.Contributions made under barter elementA system built by the International Space Agency’s partners, each funding their share of usageInternational Space Station By providing services of the same amount as his contribution. As of 2017, ESA has fulfilled the responsibilities of its five missions.a television.

The unpressurized service module takes the form of a cylinder with a diameter of 4.1 meters and a length of 2.7 meters (4 meters for the engine), including four solar panels and a span of 19 meters when deployed. It is designed and manufactured by Airbus.One Lots of With a total weight of just over 13 tonnes, the module will carry 8.6 tonnespropellant It will power a main propulsion system and 32 micro thrusters. In addition to primary propulsion and attitude control capabilities, it will provide electrical power, thermal control (keeping the vehicle at the right temperature) and provide the power needed for the vehicle to function properly. In addition to storing water resources,oxygen and D’nitrogenit will also be able to carry additional cargo.

Orion spacecraft’s first uncrewed mission around the moon

Orion’s first mission, as Artemis Project back moon, expected in 2021.baptized Artemis 1the mission will include an uncrewed test flight around the moon with a trajectory similar to the mission Apollo 8 Use gravity monthly earnings speed and propelled itself nearly 70,000 kilometers from the Moon and nearly 500,000 kilometers from Earth—more distances than any human has traveled. On the return trip, Orion will fly by the Moon before returning to Earth.The mission will last about 20 days and will end with a swim in the Pacific Ocean without the service module, which will be detached from the vehicle andatmosphere.

The success of Artemis 1 sets the stage for a U.S. return to the moon from 2024

The purpose of the mission is to verify the performance of the capsule and service module, as well as the performance of the capsule and service module, before being used for crewed flight. launcher SLS.This test flight will pave the way for the first crewed mission (Artemis 2), followed by Artemis 3, which will send two astronaut Americans, a woman and a man, will land on the moon in 2024 (if Donald Trump’s successor keeps that date).

As a reminder, the Orion capsule has already made a test flight without its service module. Produced and baptized in December 2014 Discovery Flight Test 1 (EFT-1), the purpose of this flight was to test heat shieldthe largest ever capsule (5 meters in diameter), which was then used to validate the capsule’s systems such as avionics, attitude control and parachute. In July 2019, NASA tested emergency launch abort system (Rescue Tower). The purpose of the test is to test the evacuation of astronauts in near-real conditions in the event of a problem or explosion of the launcher shortly after launch.
