Space Rocket History #59 – Ranger 8-9, and Intelsat I

In total Ranger 9 transmitted 5,814 good contrast photographs during the final 19 minutes of flight. The last image taken before impact had a resolution of 0.3 meters per pixel. The spacecraft encountered the lunar surface after 64.5 hours of flight.  Impact occurred at 14:08:19 UT right on target in the Alphonsus crater. Impact velocity was 2.67 km/s. The spacecraft performance was excellent.

Space Rocket History #50 – Blue Gemini – 1963

“Blue Gemini” was the tag name for an Air Force manned space flight program to develop rendezvous, docking, and transfer for military purposes, using Gemini-type spacecraft.
