NASA's Artemis II mission has advanced as its Space Launch System rocket and Orion spacecraft arrived at Launch Pad 39B at Kennedy Space Center. The overnight rollout marks a crucial step toward the first crewed Artemis flight, set to orbit the Moon. Engineers now prepare for prelaunch tests ahead of sending four astronauts on a 10-day journey.
On Saturday, January 17, at 6:42 p.m. EST, NASA's crawler-transporter 2 completed a 4-mile journey from the Vehicle Assembly Building to Launch Pad 39B at Kennedy Space Center in Florida. The fully stacked Space Launch System rocket and Orion spacecraft moved at a top speed of 0.82 mph, taking nearly 12 hours for the transfer. During the rollout, teams paused briefly to adjust the crew access arm, which will allow astronauts to board the Orion spacecraft on launch day.
In the coming days, technicians will conduct a wet dress rehearsal, simulating launch procedures no later than February 2. This test involves loading the rocket with cryogenic propellants, executing a full countdown sequence, and then draining the fuels safely. NASA may perform additional rehearsals if needed, potentially rolling the stack back to the Vehicle Assembly Building for inspections or modifications.
The Artemis II mission will carry NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, alongside Canadian Space Agency astronaut Jeremy Hansen. The crew plans to spend about 10 days traveling around the Moon before returning to Earth. This flight represents a major milestone in NASA's efforts to return humans to the lunar surface, establish a sustained presence there, and ultimately prepare for crewed missions to Mars.
