The project was still too expensive, however, in the eyes of Administrator Goldin. [28][29], No follow-up missions to New Horizons have been formally planned, but at least two mission concepts have been studied. You can thank the Pluto Underground",, "Postage for Pluto: A 29-cent stamp pissed off scientists so much they tacked it to, "Pluto Mission a Go! Other plutons have fatter shapes that have a roof and a floor. Shortly after the New Horizons flyby, Stern suggested a Charon lander as a follow-up that would observe Pluto from Charon's surface. The only true way to tell the difference is by mapping and analyzing the details of the rocks that are exposed along with the geology of the surrounding area. Power and propulsion would come from the bimodal MITEE nuclear reactor system.[18]. According to New Horizons principal investigator Alan Stern, “If we send an orbiter, we can map 100 percent of the planet, even terrains that are in total shadow." [24] Between April and June 2015, New Horizons began returning images of Pluto that exceeded the quality that the Hubble Space Telescope could produce. Two scientists who attended the event, World Space Foundation president Robert Staehle and JPL scientist Stacy Weinstein, were inspired by Pluto's status on the stamp, such that they started to inquire about the feasibility of sending a spacecraft to Pluto. [7] The spacecraft's minimalistic design was to allow it to travel faster and be more cost-effective, in contrast to most other big-budget projects NASA were developing at the time, such as Galileo and Cassini. Planetas que no tienen una superficie bien definida, ya que están compuestos mayoritariamente por fluidos. Los pequeños compañeros de Plutón These have a conduit of some sort that fed magma into them, usually called a feeder dike (if it's flat) or a stock (if it's round). Sala je bila puna, i rijetko je tko htio propustiti priču u nastajanju. Camino a la Tierra. [8] Alan Stern, as a compromise, reached an agreement with Russian Space Research Institute scientists in Moscow, in which Pluto Fast Flyby would be launched atop a Proton rocket, saving NASA over US$400 million in launch costs. Interest in a mission to the Kuiper belt arose such that NASA instructed the JPL to re-purpose the mission as not only a Pluto flyby, but also a Kuiper belt object (KBO) flyby. Described as a "radical" mission concept, the mission would see two spacecraft being sent to Pluto. In 1992, NASA's Jet Propulsion Laboratory (JPL) proposed the Pluto Fast Flyby mission. New Horizons had its closest approach to Pluto on 14 July 2015—after a 3,462-day journey across the Solar System. Su interior probablemente es similar al de otras lunas heladas del sistema solar. New Horizons captured its first (distant) images of Pluto in late September 2006, during a test of the Long Range Reconnaissance Imager. If New Horizons had travelled through such a ring system, there would have been an increased risk of potentially disabling micrometeoroid damage.[27].

Scientists to Push for Orbiter Mission". [12][13] Engineers at the Jet Propulsion Laboratory, inspired by the "Not Yet Explored" status of Pluto, also started to put forward ideas about a mission to Pluto. The formation and fate of plutons is an important, long-standing scientific problem. It appears that they need help from regional tectonics that pulls the crust apart—the same thing that favors volcanoes at the surface. Magma is less dense than rock and tends to rise as buoyant bodies. Plutons may readily melt their way upward in the lower crust, but they have a hard time reaching the surface through the cold, strong upper crust. «De hecho, si pones a la Tierra donde está Plutón, ¡quedaría excluida!», le dijo Stern a CNN en 2015.
