Space Rocket History #195 – Apollo 10 – Lunar Module Testing

When Stafford and Cernan were ready for undocking they discovered the Lunar Module had slipped three and a half degrees out of line with the command module at the latching point, possibly due to loose mylar collecting on the docking ring…

Space Rocket History #194 – Apollo 10 – Acquisition of Signal & Lunar Orbit

The six-minute retrograde maneuver seemed interminable, just as it had to Borman’s crew on Apollo 8, but the engine kept firing and the Apollo 10 crew’s confidence in it kept growing. When the engine finally shut down and they were sure that it had done its job, Stafford and Cernan had time to look at the lunar surface. They likened one area to a volcanic site in Arizona. Shortly, Stafford forced his attention back inside the cabin and told his crew-mates that he thought the best thing to say when they got back in radio contact with mission control was, “Houston, tell the earth we have arrived.”

Space Rocket History #193 – Apollo 10 – Coasting to the Moon & Loss of Signal

Stafford, Cernan, and Young were the first Apollo astronauts to be free from illness during the mission, although Cernan experienced a slight vestibular disturbance. Like all their colleagues who had flown before, once they unbuckled from the couches they had a stuffy feeling in their heads. This lasted for 8 to 10 hours for Stafford and Young; Cernan gradually lost the sensation over the next two days.
