After a very close flyby of the Moon, the Orion capsule begins its return to Earth

The Orion space capsule made a very close flyby of the lunar surface, the last major maneuver of the mission.

NASA’s Orion space capsule flew over the Moon on Monday less than 130 kilometers from its surface, a spectacular maneuver that marks the beginning of the return trip to Earth of this first mission of the Artemis program.

By making this flyby very close to the surface, the spacecraft took advantage of the Moon’s gravitational pull to propel itself on its return trajectory.

Communication with the capsule was interrupted for 30 minutes when it passed behind the far side of the Moon. It was also to fly over the landing sites of the Apollo mission.

last big move

The essential thrust of the European Service Module main engine, which propels the capsule, lasted just over three minutes.

It was the last big maneuver of the mission. The latter began with the liftoff of NASA’s new megarocket on November 16, for a journey that should last 25 and a half days in total.

Orion will now only make slight course corrections until it touches down in the Pacific Ocean off the US city of San Diego on Sunday, December 11 at 5:40pm GMT. She will be recovered and hoisted aboard a US Navy ship.

A sustainable presence on the Moon as a goal

During the mission, Orion spent about six days in a remote orbit around the Moon.

A week ago, this new spacecraft broke the distance record for a habitable capsule, venturing just over 432,000 km from our planet, beyond the Apollo missions.

The capsule does not carry a passenger, the purpose of this Artemis 1 mission is to verify that the vehicle is safe for a future crew.

The main objective is to test the resistance of Orion’s heat shield -the largest ever built- when it enters the Earth’s atmosphere at a speed of 40,000 km/h. It will have to withstand a temperature half as hot as the surface of the Sun (2800°C).

With the Artemis program, the Americans intend to establish a lasting presence on the Moon, in order to prepare for a trip to Mars.

The Artemis 2 mission will take astronauts to the Moon, even without landing there. This honor will be reserved for the crew of Artemis 3, which will land for the first time on the South Pole of the Moon. Officially, these missions will take place in 2024 and 2025, respectively.
