NASA’s Mega Artemis II Rocket Moves to Launch Pad for Historic Moon Mission

NASA has successfully transported its colossal Space Launch System (SLS) rocket to the launch pad at Kennedy Space Center, Florida, as final preparations ramp up for the first crewed mission to the Moon in over 50 years.

Standing 98 meters tall, the Artemis II rocket completed its 4-mile (6.5 km) journey from the Vehicle Assembly Building to Launch Pad 39B over nearly 12 hours. The rocket, mounted on a massive crawler-transporter, moved at a steady pace of 0.82 mph (1.3 km/h), giving space enthusiasts around the world a chance to witness this slow-motion engineering marvel via live coverage.

With the rocket now positioned at the pad, NASA will conduct a series of final system checks, countdown rehearsals, and a “wet dress rehearsal”, which tests fueling operations and pre-launch procedures. The earliest possible launch of Artemis II is set for 6 February 2026, with additional windows available later in February, March, and April.

Artemis II Crew: Preparing for Lunar Orbit

The mission’s four astronauts—Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen—observed the rocket’s journey at Kennedy Space Center. In just a few weeks, they will strap into the Orion spacecraft atop the SLS, ready for the 10-day lunar orbit mission.

Artemis II will be the first crewed lunar mission since Apollo 17 in 1972, and NASA states it may take its astronauts further into space than any humans before. While Artemis II won’t land on the Moon, it will provide critical data and experience for Artemis III, NASA’s upcoming mission targeting a lunar south pole landing. Artemis III is currently scheduled for no earlier than 2027, with experts projecting 2028 as a realistic earliest date.

Astronaut Christina Koch described seeing the rocket as “an amazing feeling,” highlighting the crew’s readiness and focus. Hansen emphasized the mission’s potential to inspire humanity, pointing out that seeing humans orbit the Moon may make people appreciate the Moon from a new perspective.

Mission Overview: Earth Orbit to Lunar Far Side

The Artemis II mission will begin with two days in Earth orbit, climbing to 40,000 miles out, roughly a fifth of the distance to the Moon. Koch explained that the crew will experience Earth as a single ball through the spacecraft window, followed by a journey a quarter of a million miles away. During their time orbiting the far side of the Moon, the astronauts will have three hours dedicated to lunar observation, capturing images and studying geology to inform future Moon landings.

European Space Agency’s Key Contribution

A critical component of the Orion spacecraft is the European Service Module, built in Bremen, Germany, by Airbus. The module provides propulsion, life support, and energy, enabling the spacecraft to reach lunar orbit. Sian Cleaver, spacecraft engineer at Airbus, explained:

“The European Service Module is essential—we simply cannot reach the Moon without it. Its solar arrays generate power, while tanks supply oxygen, nitrogen, and water for life support aboard Orion.”

Why Artemis II Matters

NASA’s Artemis II mission marks a historic milestone in human space exploration, paving the way for the next generation of Moon missions and potential future lunar colonization. The combination of advanced SLS technology, Orion spacecraft systems, and international collaboration positions Artemis II as a pivotal step in humanity’s return to the Moon.
