Space Rocket History #273 – Apollo 13 – Free Return – Part 3
Lovell toggled the “master arm” switch to On and glanced around to see if everything else was in order. Guidance control was set to “Primary Guidance”; thrust control was on “Auto”; engine gimbals were enabled; the propellant quantity, temperature, and pressure looked good; the ship was…

Space Rocket History #270 – Apollo 13 – The News Breaks
Cronkite did not look good. He called Schirra over and thrust a sheet of wire-service copy at him. Schirra scanned the text hurriedly, and with each sentence his heart sank. This was bad. This was worse than bad. This was . . . unheard of. He had a thousand questions, but there wasn’t time to…

Space Rocket History #227 – Apollo 11 – Rendezvous, Docking and Jettisoning
The ascent of the Eagle was strikingly swift compared with the liftoff of the huge Saturn V rocket from Cape Canaveral. Of course for the Moon launch, there was no atmosphere resisting Eagle, and there was only one-sixth gravity to overcome. Homepage with Pics
-
Space Rocket History #226 – Apollo 11 – Moon Launch
Until now they had been focused on reaching the moon, landing, taking a walk on its surface, setting up experiments, exploring, and gathering evidence. With those tasks completed and their lunar bounty was board, the top priority was to fly back to Earth. Homepage with Pics
