Space Shuttle Endeavour successfully lifted off into space this morning from Kennedy Space Center in Florida. This is the shuttle's final mission (STS-134), led by mission commander Mark Kelly. The crew will be delivering the Alpha Magnetic Spectrometer to the International Space Station, among other science projects and spare parts.
You can watch the launch below (I attempted to embed the code from NASA's website, if it doesn't work, watch it here):
After nearly a month long delay due to a heater malfunction, the launch went flawlessly. Endeavour is the youngest of the shuttles, built to replace the Challenger, which was tragically lost in a 1986 launch accident. Endeavour saw it's first flight in 1992, almost exactly 19 years ago. After almost two decades of service, the heater malfunction shows Endeavour age and the need for replacements. The other shuttles have been in service for over 30 years.
After Endeavour's final 16-day mission is complete, the shuttle will be cleaned and prepared for public display at the California Science Center, a museum in Los Angeles. The final planned shuttle mission will be STS-135, the final voyage of Atlantis, scheduled for mid-July.
