Launch of the seventeenth Commercial Resupply Services mission on board a Falcon 9 rocket as seen from my back yard. Originally scheduled for May 3rd, the launch was delayed and took place on May 4th at 2:48 AM local time.
Launch of Space Shuttle Endeavour (STS-100). Even from 20 miles away (give or take), a shuttle launch was always impressive to watch. The primary mission of STS-100 was to install the Canadarm2 robotic arm on the International Space Station.
