The Artemis II launch is tonight. Here's how to watch it live.

As launch time approaches for NASA's first moonshot in more than half a century, anticipation is building for the Artemis II mission, which will send a crew of four astronauts on a nine-and-a-half-day voyage around the moon and back. Here's how to watch tonight's launch — and where it will be visible to skywatchers in person.

What time will the Artemis II launch happen?

The launch window for Artemis II opens at 6:24 p.m. EDT Wednesday and closes two hours later, at 8:24 p.m. EDT.

If the countdown and pre-flight checks go exactly according to plan, the giant Space Launch System rocket will roar to life and lift off from the Kennedy Space Center in Florida at 6:24 p.m. EDT. But there could be a variety of delays along the way, so launch could slide to a later point within that two-hour window.

If it's delayed further, the next opportunity for launch would be a two-hour window beginning at 7:22 p.m. EDT Thursday.

Where to watch the Artemis II launch on TV

Where will the Artemis II launch be visible in person?

NASA offers viewing packages to watch launches from the Kennedy Space Center Visitor Complex, but those tickets are all sold out.

If the weather is clear, people across most of Florida and southeastern Georgia may be able to spot the rocket on its way to space if they look up at the right time. NASA shared a visibility map showing where and when people can see it it, between about 10 seconds to 70 seconds after liftoff, depending on their distance from the launch site.
