The crawler-transporter that will carry NASA’s Space Launch System (SLS) and Orion spacecraft to Launch Pad 39B for launch on Exploration Mission-1 in 2017 recently passed the first phase of an important milestone test at Kennedy Space Center in Florida.
CT-2 returned to the VAB on Jan. 31 so work can continue to install new roller bearing assemblies on the B and D truck sections. Another test is scheduled for November, after installation of the second set of bearings has been completed.
Upgrades to CT-2 are necessary in order to increase the lifted-load capacity from 12 million to 18 million pounds to support the weight of the mobile launcher and future launch vehicles, including the SLS and Orion.
