NASA's Orion Spacecraft Arrives at Vehicle Assembly Building for Artemis II Mission
The Orion spacecraft has been transported to NASA's Vehicle Assembly Building, marking a significant step toward the Artemis II mission scheduled for early next year.
NASA's Orion spacecraft, designated for the Artemis II mission, has been moved to the Vehicle Assembly Building (VAB) at Kennedy Space Center in Florida. This relocation is a pivotal step in preparing for the mission, which aims to send four astronauts around the Moon early next year.
The spacecraft's journey covered approximately six miles within the space center. Despite the ongoing government shutdown that began on October 1, NASA and its contractors continue to advance the Artemis II preparations, following White House approval to proceed with the program.
Artemis II will be the first crewed flight of the Orion spacecraft, developed by Lockheed Martin. The mission's crew includes astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen. Their 10-day flight will mark the first human journey to the Moon's vicinity since 1972.
Prior to its arrival at the VAB, the Orion spacecraft underwent several preparatory steps. Technicians filled it with hydrazine and nitrogen tetroxide propellants for its main engine and maneuvering thrusters. High-pressure helium and ammonia coolant were also loaded into its propulsion and thermal control systems. Additionally, the Launch Abort System was installed to ensure crew safety during launch.
In the coming days, cranes will lift the 78,000-pound spacecraft within the VAB to position it atop the Space Launch System (SLS) heavy-lift rocket. This integration will create a 322-foot-tall launch vehicle, ready for final tests and checkouts inside the VAB.
A critical upcoming activity is a countdown rehearsal with the Artemis II crew. The astronauts will practice launch-day procedures inside the Orion spacecraft, configuring the cockpit for flight. This event will occur without fueling the rocket.
Further tasks include testing the rocket's destruct system, designed for use if the vehicle deviates from its course after liftoff. NASA plans to roll the SLS rocket and Orion spacecraft to Launch Complex 39B, likely in January, to conduct a practice countdown involving fueling with super-cold liquid hydrogen and liquid oxygen.
Charlie Blackwell-Thompson, NASA's Artemis II launch director, expressed confidence in resolving previous hydrogen leak issues, stating that officials believe the problem has been "put to bed" after design changes and improved fueling procedures during the Artemis I countdown.
If all tests proceed without major issues, the launch team will prepare for the actual launch attempt a few days after the final rehearsal. The Artemis II mission represents a significant milestone in NASA's efforts to return humans to lunar exploration.
