Gemini Space Program the Gemini


The Von Braun team had quickly traveled to the Redstone Arsenal located in Huntsville, Alabama to work on the Explorer satellite and were working on a moon rocket booster -- the Saturn which was to produce 1.5 million pounds of thrust which was more than a sufficient amount to boost the new spacecraft into orbit. It is reported that the storability of the fuels also were a positive factor for NASA as the vehicle could be fuel without being unloaded and refueled traveling through extended holds with cryogenic fuels such as liquid oxygen. (NASA, 2000, paraphrased) The following figure shows the final Gemini design.

The Space Rendezvous Apparatus and Method Patent was issued in July, 1966 and reports that it is an invention that "relates to an apparatus and method for effecting a space rendezvous and more particularly relates to an in-transit or linear rendezvous mode of space transport employing trajectory operations conducted by two or more individually launched space units adapted to rendezvous in-transit for assembly into a single spacecraft." (United State Patent Office, 1966)

It is reported by the U.S. Patent Office that when a rocket booster is involved in connection with this type of operation "the booster has been designed to effect a docking in rendezvous with a payload before the rocket began its planned, out-or-orbit flight. The limitations inherent in designing an apparatus for use in connection with 'orbital rendezvous' operations severely restrict features of reliability, safety, vulnerability, availability and versatility, which factors are of paramount concern to the efficient achievement of any particular space mission." (United State Patent Office, 1966) What was provided by this invention was an apparatus and method in which space rendezvous and docking are not any longer restricted to satellite orbits but were after this invention able to be performed at any altitude "and in parabolic or hyperbolic orbits wherein the rendezvousing objects proceed at or near local escape velocity." (United State Patent Office, 1966) This type of apparatus is stated to comprise "a rocket booster having a thrush unit forming a uniquely arranged docking face on the fore-end thereof adapted to receive and be coupled to a manned or unmanned payload unit pursuant to in-transit space rendezvous." (United State Patent Office, 1966) Also enabled by this invention was the ability of two objects to be able to rendezvous and dock in 'high energy orbit'…" (United State Patent Office, 1966)

Summary & Recommendations

This work has examined the Gemini space program and information gained in this specific study includes information concerning the design and construction of a rocket booster system for the Gemini program that had not been previously utilized by NASA which allowed for rendezvous whether the spacecraft was in an parabolic or hyperbolic orbits and as well the thrust of the unit enabled the rendezvous and docking of two craft in a high energy orbit. Due to the brief nature of this study there are contributions that the Gemini space program made that have not been reviewed and it is therefore suggested that in order to better understand the contributions of the Gemini space program that a more in-depth study be conducted.
