Artemis II Moon Rocket Arrives at NASA Launch Pad
NASA’s Artemis II mission has reached a significant milestone with the arrival of its SLS (Space Launch System) rocket and Orion spacecraft at Launch Pad 39B. This event took place at 6:42 p.m. EST on January 17, 2026, after a nearly 12-hour journey from the Vehicle Assembly Building (VAB) located at Kennedy Space Center in Florida.
Transport to Launch Pad
The transport was executed by NASA’s crawler-transporter 2, which navigated a distance of approximately 4 miles. The crawler moved at a maximum speed of 0.82 mph, ensuring the safe delivery of the towering rocket and spacecraft. Upon reaching the launch pad, the rocket paused for a planned repositioning of the crew access arm. This arm is crucial for providing astronauts access to the Orion spacecraft on launch day.
Preparation for Wet Dress Rehearsal
In the following days, engineers and technicians will focus on preparations for the wet dress rehearsal. This critical test is scheduled for no later than February 2, 2026. During this rehearsal, the team will carry out the following:
- Load the rocket with cryogenic propellants.
- Conduct a full countdown sequence.
- Practice safely draining the propellants from the rocket.
These operations are essential steps ahead of the first crewed Artemis mission.
Possibility of Additional Tests
If necessary, additional wet dress rehearsals will be conducted to guarantee that the vehicle is thoroughly prepared for its flight. Following the rehearsal, there might be a need to return the SLS and Orion to the VAB for further assessments and adjustments before the impending launch.
About the Artemis II Test Flight
The upcoming Artemis II test flight will mark a historic journey. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch will be joined by Canadian Space Agency astronaut Jeremy Hansen. The mission will last approximately 10 days, taking the crew around the Moon and back.
This mission is a crucial step towards establishing a sustained U.S. presence on the Moon. It also sets the foundation for future crewed missions to Mars.
