Space Rocket History #106 – Apollo: The Mode Decision – Part 1

Posted on March 26, 2015

The mode that Apollo would use to land on the moon was the most studied, analyzed, and debated decision made for the lunar landing program. There were four main choices Direct-ascent, Earth-Orbit Rendezvous, Lunar-Orbit Rendezvous, and Lunar Surface...
