History of the Saturn 1B Before there was the Saturn V, there was the Saturn 1B, the NASA test bed for Apollo flight hardware. The Saturn 1B test flew versions of the Apollo Command and Service Module, and the Lunar Module. Initially tested as the second stage on the Saturn 1B rocket, the S-IVB upper stage eventually served as the third stage of the Saturn V rocket. The Saturn 1B would eventually see service as the primary launch vehicle for Earth orbit missions in the Apollo spacecraft. Features of the Rocket One of the distinctive features of the Saturn 1B is the set of cylindrical tanks that forms the rocket’s first stage. Sometimes people misidentify the tanks as re-purposed Redstone missile stages because they resemble a cluster of smaller rockets. In fact, these 70-inch diameter tanks were created using the same forms that produced the Redstone rockets. So, while they share a common lineage, they were not surplus rockets themselves. The tanks fueled eight H-1 engines, four of which could gimbal to steer the rocket while under power. Eight low profile fins ringed the base of the rocket for guidance during atmospheric flight. Saturn 1B Launches In February of 1966, NASA launched the first Saturn 1B rocket with an early version of the Apollo Command and Service Modules. There was no crew aboard. The subsequent Saturn 1B launch of Apollo 7 on October 11, 1968 certified the Apollo spacecraft for human spaceflight. It would be the last Saturn 1B launch for nearly five years.After the final Apollo moon landing in 1972, NASA used the last Saturn V to launch the Skylab Orbital Workshop. Three crews would eventually be sent to live and work in the space station. Each crew was launched aboard an Apollo Command Module carried by a Saturn 1B. Each launched aboard an Apollo Command Module carried by a Saturn 1B. The first of the three Skylab crews lifted-off on Saturn 1B vehicle SA-206 and stayed for 28 days. Their first task in orbit was to repair Skylab after an accident at launch ripped away a solar panel and sun shield. Led by Apollo 12 moon walker Pete Conrad, the crew performed a dangerous EVA and successfully rescued the space station. The Estes Saturn 1B SA-206 The Estes Saturn 1B SA-206 is a stunning 1:100 scale recreation of the Saturn 1B and Apollo spacecraft stack as it appeared in 1973 for the launch of the first Skylab crew. Every detail is there, from the Launch Escape System atop the Apollo Command and Service Module, to the first-stage H-1 engine nozzles (remove for launch). Textured body wraps, injection molded components, and other plastic formed parts add a level of realism to this Master-Level kit that every scale modeler will appreciate. Launch your finished model using one of the recommended Estes engines for a spectacular liftoff and dazzling two-piece recovery under dual parachutes. On display or in the air, the Estes Saturn 1B is a marvelous addition to any fleet.
