The Artemis 1 space mission from start to finish


AFP, published on Wednesday, August 24, 2022 at 07:27. NASA’s Artemis 1 mission, which is scheduled to lift off on Monday, is expected to last 42 days in total. The trip to the Moon, without an astronaut on board, is meticulously choreographed, and should allow for spectacular images to be collected as well as valuable scientific data. air from Launch Complex 39B at Kennedy Space Center, Florida. Its four RS-25 engines. , and two white thrusters located on each side, will produce 39 meganewtons of thrust, 15% more than the Saturn V rocket of the Apollo program. After two minutes, the thrusters will fall back into the Atlantic Ocean. After eight minutes, the main (orange) stage will detach in turn, leaving only the Orion spacecraft, whose solar panels will then deploy, attached to the rocket’s upper stage (ICPS). After circling the Earth, the latter will give the final push that will place Orion in the path of the Moon, approximately 1 hour and 30 minutes after liftoff, before dropping down as well. capsule where the astronauts will be in the future, powered by a service. module built by the European Space Agency (ESA) will take several days to reach the Moon, which it will approach by reaching only 100 km. “It’s going to be spectacular, we’re going to hold our breath,” mission flight director Rick LaBrode said weeks ago. It will climb up to 64,000 km behind the Moon, a record for a habitable capsule. Then, after passing close to the Moon again. Moon to take advantage of its gravitational assistance, it will begin its return journey, the mission is to test the heat shield of the capsule, the largest ever built (5 m in diameter). On its return to Earth’s atmosphere, it will have to withstand a speed of 40,000 km/h and a temperature of 2,800 ° C. The spacecraft will be slowed down to 480 km/h by the atmosphere, then 32 km/h by a series of parachutes, until their landing in the Californian city of San Diego. Divers will attach cables to it to be towed within hours inside a US Navy ship. – Passengers The capsule will carry a mannequin called Moonikin Campos, installed in the commander’s seat and dressed in the new NASA suit. It will record the acceleration and vibrations experienced. Also on board: two busts of women, named Helga and Zohar, and made of materials imitating bones or even human organs. One will wear an anti-radiation jacket, the other will not? A large number of cameras on board will allow you to follow the entire journey, for example from the point of view of a passenger in the capsule. the end of the solar panels will take selfies of the ship with the Moon and the Earth in the background.plan.- Embedded experiments Reality could approach science fiction with an experiment called Callisto, and inspired by the ship’s computer from Star Trek, able to trade with the crew. It is an improved version of Amazon’s Alexa voice assistant, which will be asked from the control center to adjust the light in the capsule or to read the flight data. The idea is to make life easier for astronauts in the future. In addition, a set of ten CubeSats, microsatellites the size of a shoebox, will be deployed on the upper stage of the rocket. The experiments are multiple: studying an asteroid, the effect of radiation on living organisms, the search for water on the Moon… These projects, carried out independently by companies or international researchers, take advantage of the rare opportunity of a launch into deep space.
