Had this occurred, mission rules would have called for an immediate abort as their ability to navigate the landing would be compromised. Īs flight controllers on Earth struggled with communication issues and spotty radar data, the master alarm sounded in the LM's cabin, also lighting console warnings in Mission Control. If it got much worse, Kranz would have to order an abort. "I gave the crew the go for powered descent," that is, to begin the rocket-braked landing, "and we immediately lost communications again."Īldrin had adjusted the antenna, and Mission Control had done what they could on their end, but the radio connection just kept on fading in and out. "This is now going through my mind: 'Do I have enough information to continue?' And the answer is yes" - but barely. "It was purely my decision how much information was enough," Kranz recalled.

The problems began immediately upon separation from the Command Module in which Armstrong, Aldrin and Michael Collins had ridden to the moon.
