exist2022Year11moon16Earlier on Wednesday, Artemis (Artemis) After Rocket 1’s test flight with three dummies, NASA’s Orion spacecraft deployed four planes spanning approximately63feet of solar panel on the way to the moon. After years of delays and billions in cost overruns, the rocket launched from the Kennedy Space Center in Florida.Artemis Iis the first in a series of increasingly complex missions that will enable human exploration of the Moon and Mars.
Lockheed–Martin’s Space Launch System (SLS) the moon landing rocket reached in a few seconds160kilometer/hours flying the Orion capsule, proving it is the most powerful rocket in the world, capable of carrying more payloads into deep space than any other vehicle. With its unprecedented power and capabilities, NASA’s Artemis 1 mission plans to travel beyond the Moon by approximately4Ten thousand miles, in25Return to Earth in a few days.

After reaching its initial orbit, Orion deployed its solar panels and engineers began inspecting the spacecraft’s systems. Then, about an hour and a half into the flight, the rocket’s final stage engine successfully lifted off about18minutes, giving Orion the huge boost it needs to get it out of Earth’s orbit and toward the Moon.
