The rocket will not go to the Moon but will launch the Orion spacecraft with a crew of astronauts to go to the Moon. The rocket lifts off at NASA\u2019s Kennedy Space Center in Florida. The engines give a big push that lifts the rocket off the launchpad. The engines have to push against the pull of gravity. Two minutes after launch, the rocket is high above Earth. The two white solid rocket boosters on the sides have burned all their fuel. They come off the rocket and fall back to Earth. The boosters splash into the sea. <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Eight minutes after launch, the orange core stage finishes its job. The four engines shut down. Then, the orange part of the rocket falls off and burns up in Earth\u2019s atmosphere. Only one part of SLS is left; it is called the upper stage. The upper stage has an engine. That engine pushes Orion faster and higher. The SLS rocket is so fast it could fly around Earth in only 66 minutes! Two hours after launch, Orion is more than 2,000 miles from Earth. The work of the SLS rocket is finished. The upper stage comes off and burns up. Orion finishes the trip to the Moon without the rocket in three days.<\/p>\n\n\n\n<h4 class=\"wp-block-heading has-text-align-center\">Watch a pre-launch play-by-play at NASA\u2019s Kennedy Space Center in Florida.<\/h4>\n\n\n\n<p><\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"3, 2, 1...
