Have you ever seen a halo around the Sun?
Guests look on from the terrace of Operations Support Building II as space shuttle Endeavour launches on the shuttle program's last planned night launch. Endeavour launched from Kennedy Space Center's Launch Pad 39A to begin the STS-130 mission early Monday, Feb. 8, 2010. Mission STS-130 will deliver a third connecting module, the Italian-built Tranquility node and a seven-windowed cupola, which will be used as a control room for robotics, to the International Space Station.
