NASA Mission:  Dawn The Dawn mission launched on September 27, 2007. The mission is currently still operating. It had the goal of learning more about the formation and make up of the early solar system. The  The Dawn mission orbited Vista in 2011-2012 and is currently orbiting Ceres.NASA Mission:  Gemini The Gemini 12  mission launched on November 11, 1966.  The purpose of this mission was to test astronaut’s ability to endure long missions, up to two weeks in space.  It also helped understand how to dock and orbit around the Earth and moon, and perfected re-entry and landing methods. The Gemini 12 mission ended on November 15, 1966.NASA Mission: Mariner Mariner 2 launched August 27, 1962.  It entered solar orbit on its way to Venus.  It sent information during its 110 day journey about the existence of solar winds and charged particles coming from the Sun. There was no further communication from Mariner 2 after January 3, 1963.`NASA Mission: Enterprise Enterprise was the prototype for the space shuttle fleet. On July 26,1972 Rockwell International was selected as the prime contractor for the development of the orbiter, Enterprise. On February 15, 1977 approach and launching tests began at Dryden. The first official flight was made on August 12, 1977. Over several months  a total of five  test flights  were conducted including launching  from a modified Boeing 747 Shuttle Carrier Aircraft and landing on a concrete runway at Edwards Air Force Base. The last flight was made on October 26, 1977.  All these tests confirmed aerodynamics and handling capabilities to prepare for the flights of the space shuttle Columbia.The Enterprise was actually the prototype and never flew official missions. The knowledge and experience gained from the  Enterprise allowed other space shuttles to carry  people into orbit and allowed crews to launch, recover and repair satellites. The space shuttle fleet eventually  helped build and provide supplies for the International Space Station. After successful test flights the prototype, Enterprise was retired.  Originally it was on display at the Smithsonian Institution until it was replaced there by the Discovery. The Enterprise was moved to the Intrepid Sea, Air  and Space Museum.  The grand opening of the Space Shuttle Pavilion occurred July 12, 2012. On April 27, 2015 the Intrepid was dedicated to the fallen crews of Apollo 1, Challenger and Columbia.  The dedication service included comments from astronaut Scott Kelly from aboard the International Space Station.  The Enterprise continues to educate people about NASA and its missions.
