NASA has delayed the launch of Artemis I due to problems with the SLS rocket.
10 feet, 11 inches tall and 16.5 feet in diameterUnderstanding Artemis I missionArtemis I is an uncrewed test flight that is designed to provide NASA with information that will be utilized for the two later missions.
As Orion undertakes its days-long journey to the moon, NASA engineers will evaluate the spacecraft’s systems to make sure things are operating as expected. As the brave commander heads to its destination, the engineers on Earth will continue to monitor the Orion craft as it approaches and orbits the moon, stationed about 60 miles above the lunar surface during its closest approach, NASA officials say.
“This distance is 30,000 miles farther than the previous record set during Apollo 13, and the farthest in space any spacecraft built for humans has flown,” information from NASA said. And therein lies one of the most important tests of the mission: The speed of returning to Earth. As Orion is speeding along at 300 mph, NASA expects it to produce temperatures of about 5,000 degrees Fahrenheit on the craft itself. This will test the craft’s heat shield's performance,“Our first and our primary objective is to demonstrate Orion’s heat shield at lunar re-entry conditions.
