NASA’s upgraded crawler-transporter 2 (CT-2) returns to the Vehicle Assembly Building (VAB) from its trek to Launch Pad 39B at the agency’s Kennedy Space Center in Florida. CT-2 was driven along the crawlerway and onto Pad 39B to test recently completed upgrades and modifications for NASA’s journey to Mars. The Ground Systems Development and Operations Program at Kennedy oversaw upgrades to the crawler in the VAB. The crawler will carry the mobile launcher with Orion atop the Space Launch System rocket to Pad 39B for Exploration Mission 1.
