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 #142 – Venera 4

“It seemed that the nearby and mysterious planet was resorting to tricks to hide the secrets kept beneath its cover of clouds. As the probe drew nearer, Venus’ gravitational field increased its speed. The Doppler effect altered the wavelength of the signals received on Earth. The radio operators needed to be particularly vigilant so that the information sent from the station consistently landed in the narrow “throat” of the ground-based receivers.”  Boris Chertok
