Nasa gör nytt försök att skjuta upp månraket på lördag

Artemis 1, officially Artemis I and formerly known as Exploration Mission-1, is a planned uncrewed Moon-orbiting mission and the first spaceflight in NASA's Artemis program. It is also the first flight of the agency's Space Launch System (SLS) rocket and the complete Orion spacecraft.A first launch attempt was made on 29 August 2022, but technical difficulties and uncertainty about the weather forced a cancellation. The test flight launch has not yet been rescheduled.Artemis 1 will last for six weeks and will test all the rocket stages and spacecraft that would be used in later Artemis missions. After reaching orbit and performing a trans-lunar injection (burn to the Moon), the mission will deploy ten CubeSat satellites and the Orion spacecraft will enter a distant retrograde orbit for six days. The Orion spacecraft will then return and reenter the Earth's atmosphere, protected by its heat shield, and splash down in the Pacific Ocean. The launch date of Artemis 1 was initially planned for December 2016, but it was delayed at least sixteen times due to technical issues with the SLS and the Orion spacecraft. Other factors contributing to the delays are the cost overruns (which is the main criticism of the SLS) and budget limits imposed by the federal government. After the Artemis 1 mission, Artemis 2 will perform a crewed lunar flyby and Artemis 3 will perform a crewed lunar landing, five decades after the last Apollo mission.
