NASA is just hours away from launching the most powerful rocket the world has ever seen. Lift-off from Cape Canaveral in Florida will take place between 08:33 and 10:33 ET (13:33 and 15:33 BST).
In a matter of hours, the $22 billion Space Launch System will lift off from Cape Canaveral in Florida and power an uncrewed Orion spacecraft into orbit for a 1.3 miIlion-mile voyage around the moon.
The Artemis Real-time Orbit Website will allow space fans to pinpoint where Orion is and track its distance from the Earth, distance from the moon, mission duration, and more.
