Apollo Venus flyby | KSP cinematic

In the mid-1960s, NASA considered "a three-man flyby of Venus" as part of the Apollo Applications Program, using hardware derived from the Apollo program. The proposed mission would have used a Saturn V to send three astronauts on a flight past Venus, which would have lasted approximately one year. The S-IVB stage would have been a "wet workshop" similar to the original design of Skylab. In this concept, the interior of the fuel tank would be filled with living quarters and various equipment that did not take up a significant amount of volume. The S-IVB would then be filled with propellants as normal and used to accelerate the craft on its way to Venus. Once the burn was complete, any remaining propellant would be vented to space, and then the larger fuel tank could be used as living space, while the smaller oxygen tank would be used for waste storage. Only so much equipment could be carried in the hydrogen tank without taking up too much room, while other pieces could not be immersed in liquid hydrogen and survive. This equipment would instead be placed in the interstage area between the S-IVB and the Apollo Command/Service Module (CSM), known as the Spacecraft-LM Adapter (SLA), which normally held the Apollo Lunar Module on lunar missions. To maximize the amount of space available in this area, the Service Propulsion System engine of the CSM would be replaced by two LM Descent Propulsion System engines. These had much smaller engine bells, and would lie within the Service Module instead of extending out the end into the SLA area. This also provided redundancy in the case of a single-engine failure. These engines would have been responsible for both course correction during the flight and the braking burn for Earth re-entry. Mod: BDB Music: Ends of line - Flamings The unknowing
