Space Shuttle Columbia soars into the cloud-washed sky above Cape Canaveral Lighthouse. After six scrubs from the original Sept. 25 launch date, liftoff occurred Oct. 20 at 9:53 a.m. EDT. The crew of seven comprises Commander Ken Bowersox, Pilot Kent Rominger, Mission Specialists Kathy Thornton (Payload Commander), Catherine Coleman and Michael Lopez-Alegria, plus Payload Specialists Fred Leslie and Albert Sacco. The 72nd Shuttle mission, STS-73 marks the second flight of the U.S. Microgravity Laboratory. Research is being conducted in five areas: fluid physics, materials science, biotechnology, combustion science, and commercial space processing. The lighthouse, undergoing refurbishment and upgrade, is shown with a network of nylon lines ready for canvas panels to be attached. The canvas shroud will protect the surrounding area during sand-blasting of the lead-based paint.
