Space Rocket History #197 – Apollo 10 – Ascent Stage Rendezvous, Docking & Jettisoning

As the lunar module approached, Young saw it through his sextant at a distance of 259 kilometers. Stafford and Cernan got a radar lock on the command module shortly after the insertion burn and watched with interest as the instrument measured the dwindling gap between the vehicles and demonstrated the theories of orbital mechanics in actual practice. Cernan especially liked the steady communications that kept both crews aware of what was happening.

Space Rocket History #190 – Apollo 10 – The Launch

On May 18th 1969, a king, some congressmen, other distinguished guests, and a hundred thousand other watchers waited at scattered vantage points around the Cape area. At 49 minutes past noon, Rocco Petrone’s launch team sent Apollo 10 on its way to the United States’s second manned rendezvous with the moon.

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 #186 – Apollo 10 – Commander Thomas P. Stafford

Thomas P. Stafford was the first member of his Naval Academy Class of 1952 to pin on the first, second, and third stars of a General Officer. He flew six rendezvous in space; logged 507 hours and 43 minutes in space flight and wore the Air Force command Pilot Astronaut Wings. He has flown over 127 different types of aircraft and helicopters and four different types of spacecraft.

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 #94 – Soyuz Development – Part 3

After Voskhod-2, an ideological vacuum, disorder, and vacillation cropped up in the Soviet maned space program. There was no clear-cut answer to which project should be the priority, a new series of Voskhods, artificial gravity experiments, or the construction of the Soyuzes.  However, during  August 1965 the wavering ended.  First priority was given to the Soyuzes.  A real all-hands rush job to develop and manufacture Soyuzes got underway. A new un-realistic schedule was created that required OKB-1 to supply, three Soyuz flight vehicles ready for testing, two in December of 1965 and one in January of 1966.
