NASA Photo ID: STS055(S)055 File Name: 10073167.gif Film Type: 70mm CN Date Taken: 05/06/93 Title: STS-55 Columbia, Orbiter Vehicle (OV) 102, lifts off from KSC LC Pad 39A Description: STS-55 Columbia, Orbiter Vehicle (OV) 102, lifts off from Kennedy Space Center (KSC) Launch Complex (LC) Pad 39A at 10:50 am (Eastern Daylight Time (EDT)). OV-102, atop its external tank (ET) and flanked by two solid rocket boosters (SRBs), has only moments earlier begun its ascent. Leaving the mobile launcher platform below in a cloud of exhaust smoke, OV-102 rises along side the fixed service structure (FSS) tower into the sky. An exhaust cloud fills the surrounding area. The glow of the SRB and space shuttle main engine (SSME) firings is reflected in a waterway in the foreground.
