Space Rocket History #188 – Apollo 10 – Command Module Pilot John Young

John Young enjoyed the longest career of any astronaut thus far. Over the course of 42 years of active NASA service he made six space flights and is the only person to have piloted, and been commander of, four different classes of spacecraft: Gemini, the Apollo Command/Service Module, the Apollo Lunar Module, and the Space Shuttle.

Space Rocket History #187 – Apollo 10 – Lunar Module Pilot Eugene Cernan

On Cernan’s second space flight, he was lunar module pilot of Apollo 10, May 18-26, 1969.  Apollo 10 was the first comprehensive lunar-orbital qualification and verification flight test of an Apollo lunar module. Cernan was accompanied on the 248,000 nautical sojourn to the moon by Thomas P. Stafford (spacecraft commander) and John W. Young (command module pilot).

Space Rocket History #185 – Apollo 10 – Preparations

Although the contractors had shipped excellent spacecrafts, preparations at Kennedy did not go quickly from the assembly building to the launch pad. Testing was delayed several days in order to stay out of the way of Apollo 9 pre-flight activities. Also during maintenance to the Launch Control Center, the electrical power was switched off to replace a valve. The Apollo 10 launch vehicle’s pneumatic controls sensed the power outage, opened some valves and dumped 20,000 liters of fuel on the launch pad.

Space Rocket History #184 – Apollo 9 – The Return

Even before crawling back into the command module, McDivitt said he was tired and ready for a three-day holiday.  Another 140 hours would pass before touchdown in the Atlantic, but the crew had achieved more than 90 percent of the mission objectives.

Space Rocket History #183 – Apollo 9 – Lunar Module Maneuvers Part 4

When Scott tried to release the lunar module, he did not hold the button long enough so the lander got hung on the capture latches.

Space Rocket History #182 – Apollo 9 – Lunar Module Maneuvers Part 3

On the fourth day of the flight of Apollo 9, Schweickart felt better than expected as he worked his way into the lander to get it ready for the EVA. By the time he had put on the backpack, McDivitt was ready to let him do more – to stand on the lunar lander porch at least.

McDivitt later said that the engine had come on abruptly, but with the tremendous mass, acceleration was very slow – it took the whole 5 seconds to add 11 meters per second to the speed.
