Orions first taste of space at Plum Brook Station

Interview with ESAs European Service Module test campaign manager Pierre Boisvert held at NASAs Plum Brook Station in Ohio, USA. The first Orion spacecraft will fly farther from Earth on the Artemis I mission than any human-rated vehicle has ever flown before but first it will undergo testing to ensure the spacecraft withstands the extremes of spaceflight.

Orion will be subjected to temperatures at Plum Brook ranging from 115°C to 75°C in vacuum for over two months non-stop the same temperatures it will experience in direct sunlight or in the shadow of Earth or the Moon while flying in space.

Behind the interview, Orion is being placed in a cage, called the Thermal Enclosure Structure (TES), that will radiate infrared heat during the tests inside the vacuum chamber.

The tests that will be run over the next few months will show that the spacecraft works as planned and adheres to the strictest safety regulations for human spaceflight. The European Service Module has 33 thrusters, 11 km of electrical wiring, four propellant and two pressurisation tanks that all work together to supply propulsion and everything needed to keep astronauts alive far from Earth there is no room for error.
