(MELBOURNE, FLA) — At least 100,000 people are expected for Artemis I, the first launch of NASA’s moon-focused Space Launch System rocket slated for Aug. 29.

The rocket stands at 322 feet tall, and is said to be the biggest and most powerful rocket to launch from the Space Coast in years.

Takeoff will be set for Aug. 29 at 8:33 a.m. ET. Other viewing opportunities are set for Sept. 2, and Sept. 5 (Labor Day).

The rocket is part of NASA’s Artemis program, which aims to put humans back on the moon sometime this decade. That starts with the uncrewed Artemis I mission and its plan to take an Orion capsule on a four-to-six-week journey to the moon and back. Artemis II will do the same with astronauts, then Artemis III will put two astronauts on the surface sometime after 2024.
