Le missile Mega Moon prêt à être lancé

La méga fusée Artemis I Moon est sur la rampe de lancement à[{ » attribute= » »>NASA’s Kennedy Space Center in Florida. This powerful Space Launch System (SLS) rocket is getting ready to launch the Orion spacecraft and its European Service Module. The first opportunity for launch is November 16 at 1:04 a.m. EST/local time (07:04 CET, 06:04 GMT).

Artemis I is the first mission in a large program to send astronauts around and on the Moon sustainably. This uncrewed first launch will see the Orion spacecraft travel to the Moon, enter an elongated orbit around our satellite, and then return to Earth. The Orion spacecraft is powered by the European-built module that supplies electricity, propulsion, fuel, water, and air in addition to keeping the spacecraft operating at the right temperature.

Artemis to the Moon

The European Service Modules are made from components supplied by over 20 companies in ten European Space Agency (ESA) Member States and the United States. As the first European Service Module sits atop the SLS rocket on the launchpad, the second is only 8 km (5 miles) away, as it is currently being integrated with the Orion crew capsule for the first crewed mission – Artemis II. The third and fourth European Service Modules – that will power astronauts to a Moon landing – are in production in Bremen, Germany.

The Artemis program is an international endeavor to build a permanent outpost around and on the Moon. Modules for the lunar Gateway are being built in the United States and Europe, with the first European module – International Habitat – in production in Turin, Italy, and set for launch on the fourth Artemis mission alongside the Orion spacecraft.

The first Artemis launch this week is without humans, but three mannequins have been placed in the spacecraft’s seats to conduct scientific research. Fitted with more than 5600 sensors, two mannequins will measure the amount of radiation astronauts could be exposed to in future missions with unprecedented precision. ESA is also including active radiation dosimeters in the Crew Module to get more data on how radiation levels change on a mission to the Moon – building on the leadership developed over decades of radiation research on the International Space Station.

Dates

With a November 16 launch, the three-week Artemis I mission would end on December 11 with a splashdown in the Pacific Ocean. The European Service Module detaches from the Orion Crew Module before splashdown and burns up harmlessly in the atmosphere, its job complete after taking Orion to the Moon and back safely.

Backup Artemis I launch dates include November 19. Watch the launch live on ESA Web TV.

Le vaisseau spatial Orion équipé du module de service européen volera plus loin de la Terre que n’importe quel vaisseau spatial classé humain auparavant. Cette vidéo donne un aperçu de la première mission – sans astronautes – d’Artemis, en mettant l’accent sur le module de service européen de l’Agence spatiale européenne qui exploite le vaisseau spatial. Le vaisseau spatial survolera la lune, utilisant la gravité lunaire pour gagner en vitesse et se propulser à 70 000 kilomètres de la lune, à près d’un demi-million de kilomètres de la Terre – plus loin que n’importe quel humain n’a voyagé, car il se pompera dans un vol rétrograde lointain. tournent autour de la lune. Lors de son voyage de retour, Orion fera un autre survol de la Lune avant de retourner sur Terre. Le voyage total prendra environ 20 jours et se terminera avec l’eau qui coule dans l’océan Pacifique sans l’ESU – elle se sépare et brûle dans l’atmosphère sans danger.
