National Astronomical Research Institute NARIT reveal OrionPlease return safely to the world on December 12, 2022 at 0:40 AM Thailand time. Lunar probe Orion successfully returns to Earth Landing in the Pacific Ocean, the end of the Artemis 1 mission.
Landing Time Data At 0:00, approximately 40 minutes before landing in the ocean, the Orion Crew Module successfully separated from the Service Module in preparation for entry into the Earth’s Atmosphere deck, where the Service Module was designed to cause atmospheric friction. Until it finally burned and dispersed, while the Crew Module, which is the astronaut carrying a heat shield to go through the atmosphere and parachutes to land on the surface of the ocean.
Mission Artemis 1 It is one of the hottest journeys a spacecraft will encounter. Because it is the farthest lunar orbiting mission. So for the safety of future astronauts. The researchers designed the crew module’s heat shield to withstand temperatures of up to 2,800 degrees Celsius. They also experimented with a new technique for entering the Earth’s atmosphere called a “skip entry,” which instead of a gradual descent in gradually, similar to the Apollo, but with this technique, as soon as the spacecraft reaches the upper atmosphere, it will “bounce” back into space again. and then dive back down again It’s like throwing a rock to bounce on the surface of the water.
This technique, the first to be tested on a spacecraft on a manned mission, helps the spacecraft’s aerodynamics, prevents atmospheric friction from overheating, reduces the g-forces generated, and allows for a more efficient space that travels back to the world more smoothly than before.
while the spaceship enters the atmosphere The intense heat generated around the spaceship will turn gases in the atmosphere into plasma. These plasma blocks the radio signals that the control team uses to communicate with the spacecraft. Therefore, there are times during the live that the signal will be lost.
After reaching an altitude of 8 km, the spacecraft opened its parachute. Slow down by around 500 kilometers per hour. to be less than 30 kilometers per hour Be able to touch the surface of the ocean safely. After that, boat and helicopter teams will go to retrieve the spacecraft. come back to analyze the results of different tests At the Kennedy Space Center (Kennedy Space Center) next
Mission Artemis 1 This was the first test of a new type of space probe since the most powerful rocket of our time, the SLS. Orion, or a new lunar probe that astronauts will actually use. to the global support system, which is also a new technology that can end the 26-day mission beautifully Prepare for the Artemis 2 mission, which will send astronauts to orbit the moon by 2024.
