Moving a 1.7-million-pound rocket requires a specialized railcar trek

In short: Getting a rocket to the launchpad is a feat of heavy engineering. For the Vulcan Centaur, this meant moving a 202-foot-tall platform across a 0.3-mile stretch of land. It is a high-stakes transition from hangar to pad that marks the final step before liftoff.

The rollout of the Vulcan Centaur rocket to Space Launch Complex-41 at Cape Canaveral Space Force Station occurred on January 5, 2024. This move was essential for its debut mission scheduled for January 8, which aimed to send the private Peregrine lander toward the moon. The rocket, standing 202 feet tall, weighs approximately 1.7 million pounds. To move such a massive platform, United Launch Alliance (ULA) utilized a combination of undercarriage railcars and trackmobile machines to push the vehicle along tracks up a hill to the pad.

This specific mission served as a milestone for both the rocket and the payload. The Vulcan Centaur was designed to replace the venerable Atlas V and Delta IV rockets in the ULA fleet.

Meanwhile, the Peregrine lander, built by Astrobotic, was part of NASA's Commercial Lunar Payload Services program. This initiative seeks to establish a path for the Artemis astronaut missions by utilizing private craft to deliver science payloads from NASA and Germany's DLR, as well as private memorial capsules. The logistics of these rollouts are part of a broader shift in space exploration. NASA's Commercial Orbital Transportation Services (COTS) program, for instance, has been instrumental in developing a robust U.S. commercial space transportation industry. By partnering with companies like Orbital Sciences Corporation and SpaceX, NASA aims to create a reliable and cost-effective pipeline for transporting humans and cargo to low-Earth orbit and beyond.
