Quiz: Crawling to Space

Test your knowledge about the massive vehicles that move NASA rockets from place to place.

Building a massive rocket that has the ability to reach the Moon is an amazing feat of engineering. But when it comes time to move that giant rocket from the shop to the launch pad, the necessary equipment must be of equal caliber. Enter NASA’s crawler-transporters, first dreamed up as part of the Apollo program to move the more than 6-million-pound Saturn V rocket out to the launch pad in the 1960s.

On Wednesday, February 25, crawler-transporter 2 was once again on the move. NASA’s Artemis II Space Launch System rocket traveled from Launch Complex 39B back to the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida to troubleshoot the flow of helium to the rocket’s interim cryogenic propulsion stage. Once fixed, the crawler will make the 12-hour trek back out to the launch pad to ready the rocket for the planned April 2026 launch window.

In honor of this week’s move, see what you know about the crawler-transporters—an ASME Mechanical Engineering Landmark—with this ASME quiz.
