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

Posted on June 17, 2015

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 oth...

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

Posted on July 23, 2015

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 Apo...
