Space Rocket History #200 – Luna 15

In February of 1969, the first launch of the Soviet Moon Rocket, the N-1, exploded.  By April, the Soviets still did not have a clear program of subsequent piloted Soyuz fights. In May, the Soviets watched the successful US lunar orbital flight and practice landing of Apollo 10. In June, a Lunar Sample return mission failed when the Block D stage refused to ignite. On July 3rd the second N1 launch failed with a spectacular explosion…

Space Rocket History #198 – Apollo 10 – Snoopy Returns and a Successful Dress Rehearsal

“Hey, Apollo – Houston, this is Apollo 10. Look, I know you ran some studies, but by golly, we can see Snoopy, and he isn’t too far away! He’s catching up with us. Can you talk to the FIDOS? He’s right down below us. We can occasionally see him tumbling end-over-end down below there, and he’s coming in closer each pass. That’s Snoopy’s descent stage. We can see him right down below us now, and he’s right – I thought he was a little out-of-plane, but now he’s looking more in-plane with us.” Tom Stafford Apollo 10
