Space Shuttle Endeavour STS-134 on Launch Pad

Overnight, Space Shuttle Endeavour made its way on the special crawler from the Vehicle Assembly Building (VAB) to launch pad 39A. The 3.4-mile trip began at 7:56 p.m. Thursday evening and ended at 3:49 a.m. Friday morning. Ok, can't resist, the math problem is just too good... So, how fast does the crawler travel in miles per hour?

Ground crews will continue to prepare Endeavour for launch from the pad. STS-134 Launch is scheduled for April 19th at 7:48 p.m.
