Artemis I realizará un inusual "reingreso de rebote largo" a la Tierra

By Ninian Carter

December 7, 2022 - El vehículo Orion de Artemis I rebotará como una piedra en la atmósfera de la Tierra durante su reingreso – una técnica jamás intentada por una nave espacial para pasajeros.

The uncrewed Orion spacecraft, currently flying home from the moon, must survive 2,700°C temperatures when it slams into Earth’s atmosphere on Sunday.

NASA’s $20 billion Orion vehicle will return to Earth at a speed in excess of 32,000km/h – the fastest and hottest for any crew-rated spacecraft in history.

However, NASA is hoping a technique known as “long skip re-entry” will assist the capsule during the final leg of its mission, as opposed to a single deceleration event like the ones used for returning Apollo moon missions.

Orion carries an innovative new heat shield to deal with the high temperatures, and is dependant upon the success of the skip re-entry procedure in which the spacecraft will bounce off the atmosphere, temporarily return to space and then perform a second reentry – lessening aerodynamic braking loads and temperatures, and lessening g-forces for a smoother ride.

Orion is due to splashdown in the Pacific Ocean off the coast of San Diego on Sunday, December 11 around 1740GMT.
