New Horizons is an interplanetary
space probe that was launched as a part of
NASA's
New Frontiers program. Engineered by the
Johns Hopkins University Applied Physics Laboratory (APL) and the
Southwest Research Institute (SwRI), with a team led by
S. Alan Stern, the spacecraft was launched with the primary mission to perform a
flyby study of the
Pluto system, and a secondary mission to fly by and study one or more other
Kuiper belt objects (KBOs).
On January 19, 2006, New Horizons was launched from Cape Canaveral Air Force Station directly into an Earth-and-solar escape trajectory. After a brief encounter with asteroid 132524 APL, New Horizons proceeded to Jupiter, making its closest approach on February 28, 2007. The Jupiter flyby provided a gravity assist that increased New Horizons' speed; the flyby also enabled a general test of New Horizons' scientific capabilities, returning data about the planet's atmosphere, moons, and magnetosphere.
Most of the post-Jupiter voyage was spent in hibernation mode to preserve on-board systems, except for brief annual checkouts. On December 6, 2014, New Horizons was brought back online for the Pluto encounter, and instrument check-out began. On January 15, 2015, the New Horizons spacecraft began its approach phase to Pluto.
On July 14, 2015, at 11:49 UTC, it flew 12,500 km (7,800 mi) above the surface of Pluto, making it the first spacecraft to explore the dwarf planet. Having completed its flyby of Pluto, New Horizons has maneuvered for a flyby of Kuiper belt object 2014 MU69, expected to take place on January 1, 2019, when it is 43.4 AU from the Sun.
Glynn S. Lunney (November 27, 1936 – March 19, 2021) was an American
NASA engineer. An employee of NASA since its foundation in 1958, Lunney was a
flight director during the
Gemini and
Apollo programs, and was on duty during historic events such as the
Apollo 11 lunar ascent and the pivotal hours of the
Apollo 13 crisis. At the end of the Apollo program, he became manager of the
Apollo-Soyuz Test Project, the first collaboration in spaceflight between the United States and the
Soviet Union. Later, he served as manager of the
Space Shuttle program before leaving NASA in 1985 and later becoming a Vice President of the
United Space Alliance.
Lunney was a key figure in America's manned space program from Project Mercury through the coming of the Space Shuttle. He has received numerous awards for his work, including the National Space Trophy, which he was given by the Rotary Club in 2005. Chris Kraft, NASA's first flight director, described Lunney as "a true hero of the space age", saying that he was "one of the outstanding contributors to the exploration of space of the last four decades".
