CAPE CANAVERAL, Fla. – Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, technicians prepare a new engine and generator for installation on crawler-transporter 2 CT-2). The Apollo era diesel engines were removed last month. Work continues in high bay 2 to upgrade CT-2 so that it can carry NASA’s Space Launch System heavy-lift rocket, which is under design, and new Orion spacecraft to the launch pad. The crawler-transporters were used to carry the mobile launcher platform and space shuttle to Launch Complex 39 for space shuttle launches for 30 years. Photo credit: NASA/Jim Grossmann
