NASA Photo ID: STS033(S)004 File Name: 10063655.jpg Film Type: 120 CN Date Taken: 11/27/89 Title: STS-33 Discovery, OV-103, early morning liftoff from KSC LC Pad 39B Description: STS-33 Discovery, Orbiter Vehicle (OV) 103, lifts off from Kennedy Space Center (KSC) Launch Complex (LC) Pad 39B at 7:23:29:989 am Eastern Standard Time (EST). OV-103, its external tank (ET), and solid rocket boosters (SRBs) are highlighted by spotlights during its launch into darkness. OV-103 is nearly clear of the launch tower as an exhaust cloud covers LC Pad 39B and the surrounding area. A palm tree and other vegetation in the foreground are silhouetted against the exhaust cloud and the glow of the SRB and space shuttle main engine (SSME) firings. The light colored plume with the slight "diamond shock" effect comes from the SSMEs. The STS-33 launch is the first post-Challenger nocturnal launch.
