This is a massive collaboration between NASA and SpaceX. Just like the very first time that people set foot on the moon, this is going to change the world

The Space Launch System , also known as SLS , is being rolled out to the launchpad for the very first time.

The SLS has been in development since 2011 , and it is just now being tested for its first launch.

The first test will be a wet dress rehearsal and system check for the SLS and Orion spacecraft.

Artemis 1 will be the first flight, which will go all the way out to orbit around the Moon.

Artemis 2 should come either next year or the year after, and Artemis 3 will be landing people on the moon.

The HLS Starship is a vehicle that SpaceX have been actively developing and testing since 2019 .

The idea is a fully reusable Super Heavy lift rocket with an upper stage that can not only land back on the Earth , but can also land on the Moon and even on Mars with people on board.

The FAA has delayed the launch of the Starship until March 28th .

The plan from SpaceX is to conduct one or two orbital tests where the ship and booster will probably be destroyed in the process.

Starship is extremely tall, 50 meters in height.
