In the summer of 1959, NASA Langley\u2019s John Houbolt led two study groups dedicated to figuring out how best to perform a rendezvous in space.<\/p>\n\n\n\n<p>Houbolt would become the agency\u2019s greatest champion of the Lunar Orbit Rendezvous concept, which turned out to be the method NASA used to reach the moon.<\/p>\n\n\n\n<p>NASA Langley also played a part in preparing the Gemini VII\/VI-A astronauts for their historic meeting in space.<\/p>\n\n\n\n<p>Astronauts practiced on the center\u2019s Rendezvous Docking Simulator, an apparatus installed in the rafters of Building 1244, better known as the center\u2019s hangar.

It was an exciting time, with the chance to tackle some difficult problems and opportunities to work with smart, dedicated people.

He recalled that astronauts would fly into the center aboard T-38 jets.<\/p>\n\n\n\n<p>\u201cIf you saw two or three T-38s parked out there you knew some astronauts were here for simulations,\u201d said Bergeron, who remembers chatting with the astronauts while the system\u2019s computer came on line \u2014 a process that could take as long as 30 minutes.<\/p>\n\n\n\n<p>\u201cAt the time, you didn\u2019t realize the significance of what was going on,\u201d Bergeron said. \u201cWas I excited?
