14P/Wolf
14P/Wolf is a periodic comet in the Solar System. Max Wolf (Heidelberg, Germany) discovered the comet on September 17, 1884. It was later discovered by, but not credited to, Ralph Copeland (Dun Echt Observatory, Aberdeen, Scotland) on September 23. Previously, the comet had a perihelion of 2.74 AU and an orbital period of 8.84 a; this changed to a perihelion of 2.43 AU and an orbital period of 8.28 a due to passing 0.125 AU from Jupiter on September 27, 1922. The current values have been from when the comet passed Jupiter again on August 13, 2005. Another close approach to Jupiter on March 10, 2041 will return the comet to parameters similar to the period 1925–2000.Cometography Home Page The comet nucleus The nucleus is the solid, central part of a comet, once termed a ''dirty snowball'' or an ''icy dirtball''. A cometary nucleus is composed of Rock (geology), rock, dust, and frozen gases. When heated by the Sun, the gases Sublimati ...

SpaceShipOne Flight 14P
Flight 14P of SpaceShipOne was its third powered flight, which occurred on May 13, 2004. The pilot was Mike Melvill. Details SpaceShipOne was released from White Knight at an altitude of and a speed of 120 knots (62 m/s). After ten seconds the rocket was lit, for a 55 second burn. At burn-out the altitude was and the Mach number was 2.5. The craft then coasted to an apogee altitude of . At one point during the flight, the avionics computer froze up and had to be rebooted. Melvill flew the aircraft manually until the computer became operable again. During reentry, the craft attained Mach 1.9 and deceleration of 3.5 ''g'' (34 m/s²). The craft switched to glider configuration at 55,000 feet (17.4 km). The craft returned to the spaceport A spaceport or cosmodrome is a site for launching or receiving spacecraft, by analogy to a seaport for ships or an airport for aircraft. The word ''spaceport'', and even more so ''cosmodrome'', has traditionally been used for sit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
