Space Shuttle 'Go for Launch' on July 13

Tuesday July 5, 2005
It has been nearly two and a half years since the disintegration of the space shuttle Columbia caused the grounding of the entire space shuttle fleet. For the last 29 months, the crew of the International Space Station has been down to two people and has been relying on Russian Soyuz rockets for supplies. Finally, after a two-day Flight Readiness Review meeting at NASA's Kennedy Space Center in Florida, senior managers approved a July 13 launch date for Discovery. NASA's Deep Impact Generates its own Spectacular Photo Flash
The hyper-speed demise of NASA's Deep Impact probe generated an immense flash of light, which provided an excellent light source for the two cameras on the Deep Impact mothership. Deep Impact scientists theorize the 820-pound impactor vaporized deep below the comet's surface when the two collided at 1:52 am July 4, at a speed of about 10 kilometers per second (6.3 miles per second or 23,000 miles per hour).
