NASA has released details about the launch countdown procedure for its upcoming Artemis II mission, which will send four astronauts on a journey around the Moon. According to NASA, the launch team at Kennedy Space Center in Florida will begin the countdown approximately two days before liftoff.

The crew for Artemis II includes NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency (CSA) astronaut Jeremy Hansen. The mission will mark the first crewed lunar flyby since the Apollo era.

Teams across the country will participate in the countdown process alongside the primary launch team at Kennedy Space Center. NASA's release outlines the structured sequence of events and checks that must be completed during the roughly 48-hour countdown window leading up to launch.

Artemis II is part of NASA's broader Artemis program, which aims to return humans to the lunar vicinity and eventually to the lunar surface. This particular mission is designed as a crewed test of the Orion spacecraft and Space Launch System (SLS) rocket under deep space conditions with astronauts aboard.
