Space Rocket History an Encore Presentation of Episode #42 – Satellite Killer – Polyot-1

The Space Age had barely begun when Soviet engineers started planning ways to destroy enemy satellites. Some Western analysts have speculated that a design for an anti-satellite weapon system was started at Korolev’s OKB-1 bureau as early as 1956…

Space Rocket History #122 – Apollo: Serious Problems with the Lunar Module and Grumman

Toward the end of January 1967, it was revealed that Lunar Module 1 would not reach the Cape in February, as expected. This meant, the moon landing might be delayed because the lander was not ready. But the mission planners could not wait for the Apollo engineers to iron out all the problems. They had to plan for a landing in 1969 and hope that the hardware would catch up with them.

Space Rocket History #119 – Apollo: Lunar Module Design – Part 3

At various stages of lunar module design, mockup reviews were conducted to demonstrate progress and identify weaknesses. These inspections were formal occasions, with a board composed of NASA and contractor officials and presided over by a chairman from the Apollo office in Houston.

Space Rocket History #118 – Apollo: Lunar Module Design – Part 2

The Lunar Lander originally had two docking hatches, one at the top center of the cabin and another in the forward position, or nose, of the vehicle, with a tunnel in each location to permit astronauts to crawl from one pressurized vehicle to the other…

Space Rocket History #117 – Apollo: Lunar Module Design

Since the lunar module would fly only in space (earth orbit and lunar vicinity), the designers could ignore the aerodynamic streamlining demanded by earth’s atmosphere and build the first true manned spacecraft, designed solely for operating in the spatial vacuum.

Space Rocket History #108 – Apollo: The Mode Decision – Part 3

“I would like to reiterate once more that it is absolutely mandatory that we arrive at a definite mode decision within the next few weeks. . . . If we do not make a clear-cut decision on the mode very soon, our chances of accomplishing the first lunar expedition in this decade will fade away rapidly.” Wernher Von Braun June 7, 1962.

Space Rocket History #47 – Gemini Concepts

This brings us to Project Gemini.  Gemini started after Apollo had begun, in part to answer a crucial question for Apollo. Was rendezvous and docking in orbit a feasible basis for a manned lunar landing mission?
