NASA Artemis II launch: Date, time, live stream and how to watch the historic mission live | Watch live stream Here

Artemis II launch date and time: The countdown for NASA’s Artemis II test flight is underway at the agency’s Kennedy Space Center in Florida, with members of the launch team arriving at their consoles inside the Rocco Petrone Launch Control Center. Artemis II mission marks the first time in 53 years that a crewed spacecraft is poised to depart for the Moon. The onsite countdown clock started ticking down at 4:44 pm EDT (2:14 A.M IST) to a targeted launch time of 6:24 pm (3:54 A.M IST) on Wednesday, April 1. Artemis II is the first crewed launch of NASA’s SLS (Space Launch System) rocket and Orion spacecraft.

The 32-story Space Launch System (SLS) rocket is scheduled to ignite Wednesday evening, carrying a four-member international crew that includes the first woman, the first person of color, and the first non-US citizen to embark on a lunar trajectory. With countdown officially underway, engineers are powering up flight hardware, checking communication links, and preparing the rocket’s cryogenic systems for the precise fueling sequence required to load hundreds of thousands of gallons of super-cooled liquid hydrogen and liquid oxygen.

The Artemis II crew, NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, remains in Astronaut Crew Quarters inside NASA Kennedy’s Neil A Armstrong Operations and Checkout Building. The crewmates have spent the final countdown phase focused on readiness and technical verification, remaining in quarantine under strict health monitoring and completing medical checks to ensure fitness for launch. They have been following a controlled sleep schedule and nutrition plan to maintain energy and hydration for launch, while continuing to receive regular updates on the rocket’s configuration and weather conditions from crew quarters.
