Apollo rockets powered mankind to the moon in the 60s and 70s. Now the mighty Artemis I rocket is set to blast off today from NASA's Space Launch Pad 39B for an unmanned systems test.
NASA will stream the launch on its website and on NASA TV starting at 12 am ET. YouTube will pick up live coverage at 8am ET.
Actual liftoff is set for between 8:30 am and 10:30 am ET.
If the launch is delayed you might link up with Greek mythology websites and stories to catch up with god Apollo and goddess Artemis, who were twin offspring of the big Greek god Zeus.
