Biography
Place in spaceflight history
Houbolt analyzed competing lunar-mission modes, documented the mass and operational advantages of lunar-orbit rendezvous, and elevated the proposal beyond normal review channels when he believed the concept was being dismissed without adequate consideration.
The architecture NASA selected allowed a dedicated lunar module to descend from lunar orbit while the command module remained aloft, making Apollo's landing plan achievable within available launch capacity.
