You can thank the Pluto Underground", http://arago.si.edu/index.asp?con=2&cmd=1&id=192129&img=1&pg=1, "Postage for Pluto: A 29-cent stamp pissed off scientists so much they tacked it to, "Pluto Mission a Go!  However, scientists decided that a flyby of Titan during the Saturn encounter would be a more important scientific objective. Planetas que no tienen una superficie bien definida, ya que están compuestos mayoritariamente por fluidos. This project got delayed, and in 2000 the mission was cancelled, with NASA giving the reason of cost overruns. The plan included a twelve-year trip from Earth to Pluto, mapping from orbit, multiple landings, a warm water probe, and possible in situ propellant production for another twelve-year trip back to Earth with samples.  Possible objectives discussed by the group for a follow-up mission include mapping the surface at 30 feet per pixel, observations of Pluto's smaller satellites, observations of how Pluto changes as it rotates on its axis, and topographic mapping of Pluto's regions that are covered in long-term darkness due to its axial tilt. A mushroom-shaped pluton may be called a lopolith, and a cylindrical one may be called a "bysmalith." 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. The idea was shortly scrapped, however, because of the infeasibility of miniaturizing scientific instruments aboard such a spacecraft to that size. The group started a letter writing campaign which aimed to bring to attention Pluto as a viable target for exploration. Thus plutons, and especially batholiths, go along with subduction zones that create arc volcanism. De acuerdo con un importante resultado de la teoría de la relatividad, un observador en el sistema Tierra-Plutón vería contraerse la nave en la dirección del movimiento. That is, plutons are defined by the presence of plutonic rocks. , In May 1989, a group of scientists and engineers, including Alan Stern and Fran Bagenal, formed an alliance called the "Pluto Underground". , Another mission concept, known as Pluto 350, was developed by Robert Farquhar of the Goddard Space Flight Center, with Alan Stern and Fran Bagenal of the Pluto Underground, who both served as study scientists for the project.  On 15 April 2015, Pluto was imaged showing a possible polar cap.  The concept describes an entrycraft that would brake using the drag of Pluto's thin but highly spread-out atmosphere. - Upravo su mi telefonirali iz policije - objasni Miki ulazeći u auto - da je nekoliko divljih životinja pobeglo iz cirkusa. 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).  However, such a lander would only observe the Charon-facing hemisphere of Pluto, as Pluto and Charon are tidally locked. Eventually, despite official selection of scientific instruments and the appointment of several investigators, then-Science Mission Directorate Edward J. Weiler ordered the cancellation of the entire Pluto and Kuiper belt mission in 2000, citing growing budget constraints, which had plagued the project since its inception in 1992. Power and propulsion would come from the bimodal MITEE nuclear reactor system.. Aunque, quizás esta idea sea nuevamente cambiada en poco tiempo. An alternative plan which was considered at one point was to send to Pluto a configuration of the Mariner Mark II spacecraft, which would weigh 2,000 kilograms and cost US$3.2 billion, in sharp contrast to Pluto 350's $543 million cost. Exploring Pluto was contemplated since its discovery by Clyde Tombaugh in 1930, but Pluto presents significant challenges for exploration because of its small mass and great distance from Earth. A pluton exposed at the Earth's surface has had its overlying rock removed by erosion. Other plutons have fatter shapes that have a roof and a floor. One of many possibilities for the Voyager 1 spacecraft after its flyby of Saturn in 1980 was to use Saturn as a slingshot towards Pluto for a flyby as early as March 1986. The project was still too expensive, however, in the eyes of Administrator Goldin. In the United States, the Idaho, Sierra Nevada, and Peninsular batholiths are the largest. Pluto was rejected in favor of Titan, Uranus and Neptune. 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." The formation and fate of plutons is an important, long-standing scientific problem. Because no mission to Pluto was planned by any space agency at the time, it would be left unexplored by interplanetary spacecraft for years to come. Camino a Júpiter.  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. That stamp had been in so many presentations by that point, I knew it would please people to have it go along.  The probe could use electric propulsion similar to NASA's Dawn mission. Both spacecraft were to weigh only around 35-50 kilograms each (including 7 kg worth of scientific instruments), and the project would cost less than US$500 million to develop, excluding launch costs.  There are no plans as yet for a follow-up mission, though follow-up concepts have been studied.. There used to be a whole set of names for other pluton shapes, but they aren't really much use and have been abandoned. Scientists to Push for Orbiter Mission". A blister-shaped pluton that raised the overlying rocks into a dome may be called a laccolith. He works as a research guide for the U.S. Geological Survey. (See What Is a Planet?). At the time, it was thought that the atmosphere of Pluto would freeze and fall to the surface during winter, and so a lightweight spacecraft was desirable, as it would be able to reach Pluto before such an event would occur.  Because no mission to Pluto was planned by any space agency at the time, it would be left unexplored by interplanetary spacecraft for years to come.  The report, written by principal investigator Stephanie Thomas of Princeton Satellite Systems, Inc., describes a Direct Fusion Drive (DFD) mission to Pluto. They also considered the term "plutinos." Otros astrónomos opinaban que Plutón podría ser una luna de Neptuno. Bottomless plutons like these are called stocks if they are smaller than 100 square kilometers in extent, and batholiths if they're larger. Space Exploration Issue - 29c Pluto single - Scott Catalogue USA: 2577.  In 1990, because of pressure from the scientific community, including those of the Pluto Underground, engineers at NASA decided to look into concepts for a mission to Pluto. Andrew Alden is a geologist based in Oakland, California. The exploration of Pluto began with the arrival of the New Horizons probe in July 2015, though proposals for such a mission had been studied for many decades. New Horizons also photographed the surfaces of Pluto and Charon.  Stern and David Grinspoon have also suggested that an orbiter mission could search for evidence of the subsurface ocean hinted at in New Horizons data.. It would then have the option of using Charon's gravity to leave the Pluto system after all Pluto science objectives are completed and study new KBOs beyond Pluto. Nuestros astrónomos ya se han reunido para enviar a los planetas a las diferentes agrupaciones. Shallower intrusions may be called subvolcanic or hypabyssal intrusions. After an intense political battle, a revised mission to Pluto called New Horizons was granted funding from the US government in 2003. Pluto 350 aimed to send a spacecraft, weighing 350 kilograms, to Pluto. 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.  All four outer planets were explored by Voyager 2, launched in 1977, with close approaches to Jupiter, Saturn, Uranus, and Neptune. The Fusion-Enabled Pluto Orbiter and Lander was a 2017 phase I report funded by the NASA Innovative Advanced Concepts (NIAC) program. The mission heralded the same ideology as the Pluto 350 concept: small in size and cost-effective in scope, so that the spacecraft would be able to get to Pluto faster and be affordable to develop and launch. A competition was held, in which NASA would select a mission concept to fund as part of the first mission of the New Frontiers program. The mission was thus re-branded as the Pluto Kuiper Express, after briefly being billed as Pluto Express prior to the revision. , No follow-up missions to New Horizons have been formally planned, but at least two mission concepts have been studied. This can be easy to see in a pluton that was tilted so that erosion could cut through it at an angle. This is similar to NASA's Triton Hopper concept for exploring Neptune's largest moon Triton. On 4 February 2015, NASA released new images of Pluto (taken on 25 and 27 January) from the approaching probe. After Voyager 2 successfully returned data from Neptune in 1989, planetary scientists looked to Pluto as the destination for a subsequent mission. Narrow sheets of magma that form sills and igneous dikes may qualify as plutons if the rock inside them solidified at depth.

Hasta 2006, el Sistema Solar contaba con un planeta más: Plutón. A pluton (pronounced "PLOO-tonn") is a deep-seated intrusion of igneous rock, a body that made its way into pre-existing rocks in a melted form several kilometers underground in the Earth's crust and then solidified.At that depth, the magma cooled and crystallized very slowly, allowing the mineral grains to grow large and tightly interlocked — typical of plutonic rocks. Fuera del sistema solar.  New Horizons was more than 203,000,000 km (126,000,000 mi) away from Pluto when it began taking the photos, which showed Pluto and its largest moon, Charon. The stamp for Pluto, however, depicted a featureless sphere, presented with the phrase "not yet explored" in place of the name of a spacecraft. Plutón no es tan grande ni tan pequeño. One of the earliest concepts was for a 40-kilogram spacecraft that would reach Pluto in five to six years. The cancellation of Pluto Kuiper Express angered some of the space-exploration scientific community, which led to groups, such as The Planetary Society, lobbying NASA for either a reboot of the Pluto Kuiper Express or a restart of a mission to Pluto. Early mission proposals. Plutón, designado (134340) Pluto, es un planeta enano del sistema solar situado a continuación de la órbita de Neptuno.Su nombre se debe al dios mitológico romano Plutón (Hades según la mitología griega).En la Asamblea General de la Unión Astronómica Internacional celebrada en Praga el 24 de agosto de 2006 se creó una nueva categoría llamada plutoide, en la que se incluye a Plutón. On 20 March 2015, NASA invited the general public to suggest names for surface features that will be discovered on Pluto and Charon. Incluso algunos siguen tratando de debatir este cambio, pero hasta el día de hoy Plutón sigue siendo un planeta enano. There are a slew of partial synonyms based on a pluton's size and shape, including batholith, diapir, intrusion, laccolith, and stock.  In response to the backlash caused by the cancellation of Pluto Kuiper Express, it was decided to inaugurate a new class of missions that would fit between the big-budget Flagship Program and the low-budget Discovery Program, creating a compromise for missions such as the former Pluto Kuiper Express, which proved to be too expensive for the Discovery Program.  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. .... , a znalo se o tim tijelima, tada, tako malo. This became known as the Pluto Express, and eventually the Pluto-Kuiper Express. The mission leader, S. Alan Stern, confirmed that some of the ashes of Clyde Tombaugh, who died in 1997, had been placed aboard the spacecraft..  The spacecraft were intended to be launched using Titan IV rockets, which would have cost US$400 million each, thus raising the budget to over US$1 billion. Stern envisaged the probe being launched in 2030, marking the 100th anniversary of Pluto's discovery, and spending 7-8 years traveling to the Pluto system.  New Horizons was launched successfully on 19 January 2006. The Geological Society of America, among other critics of the proposal, sent a quick protest, and a few days later the IAU decided on its epochal definition of "dwarf planet" that banished Pluto from the register of planets. Ne conecteaza cu cea mai adanca, subconstienta parte a personalitatii, si pe taramurile subconstientului colectiv, asa ca prin Pluton ne putem curata prin fluxul curentului al schimbarii colective. A subsequent flyby of Pluto was impossible, because the close approach of Titan meant it was also on a trajectory that slingshotted it upwards out of the ecliptic. New Horizons used a remote sensing package that includes imaging instruments and a radio science investigation tool, as well as spectroscopic and other experiments, to characterize the global geology and morphology of Pluto and its moon Charon, map their surface composition and analyze Pluto's neutral atmosphere and its escape rate. Magma is less dense than rock and tends to rise as buoyant bodies. , In October 1991, the United States Postal Service released a series of stamps commemorating NASA's exploration of the Solar System. Se supone, por simplificación, que existe un sistema inercial respecto al cual la Tierra y Plutón están en reposo; en particular, se ignora el movimiento de los dos planetas alrededor del Sol. A fusion reactor would be used to send a 1000 kg orbiter and lander to the Pluto system in only four years (more than twice as fast as New Horizons).. , A Pluto orbiter/lander/sample return mission was proposed in 2003.  Because of growing budget constraints, the dual-spacecraft concept was scrapped in favor of sending a single spacecraft to Pluto. The two Voyager missions had the success criteria of just one of them reaching Saturn, which they far exceeded. If New Horizons had travelled through such a ring system, there would have been an increased risk of potentially disabling micrometeoroid damage.. , In August 1992, Staehle telephoned Pluto's discoverer, Clyde Tombaugh, requesting permission to visit his planet.  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. Otherwise, it may take geophysical techniques to map the pluton's three-dimensional shape. Se han descubierto muchos cuerpos en la misma región, comparte el espacio con otros cuerpos celestes. Su interior probablemente es similar al de otras lunas heladas del sistema solar. Camino a Marte. Dinamičari su bili presretni, počinjalo se vidjeti da su bili u pravu. Global Aerospace Corporation presented a Pluto lander concept titled "Pluto Hop, Skip, and Jump" at the 2017 NIAC Symposium in Denver, Colorado. Once on Pluto's surface, the vehicle would exploit Pluto's low gravity to hop between sites using propellant. No los salvan ni los mayas . Sala je bila puna, i rijetko je tko htio propustiti priču u nastajanju. Then there are plutons that have no floor, or at least no evidence of one. Se darán una nueva vuelta por el Universo. La Selección Colombia avergonzó al país, o al menos así lo indicaron los periodistas deportivos de más nombre en el territorio. It was named in homage of the Mars Underground, another group of scientists that successfully lobbied for the restart of missions to Mars, following the lack of such since the Viking program. The two probes of the Voyager program, launched in 1977 to explore Jupiter and Saturn, had also the ability for an extended mission to other targets. Additionally, morale among the team and personnel working on interplanetary missions was low following the loss of the Mars Observer spacecraft during its attempted Areocentric orbit insertion in August 1993. , Pluto's small moons, discovered shortly before and after the probe's launch, were considered to be potentially hazardous, as debris from collisions between them and other Kuiper belt objects could have produced a tenuous dusty ring.  Between April and June 2015, New Horizons began returning images of Pluto that exceeded the quality that the Hubble Space Telescope could produce. Durante muchos años se creyó de que Plutón era un satélite del planeta Neptuno. New Horizons captured its first (distant) images of Pluto in late September 2006, during a test of the Long Range Reconnaissance Imager. In April 2017, a workshop met in Houston, Texas to discuss ideas for a follow-up mission. For many years, people had waved that stamp around as sort of a call to arms, as a motivating graphic: "Not yet explored". Tienen pinta de terrícolas y un Gran Final les espera . Described as a "radical" mission concept, the mission would see two spacecraft being sent to Pluto. Plutón, el planeta olvidado que ya no es planeta. Scientific observations of Pluto began five months before the closest approach and continued for at least a month after the encounter. At the time of cancellation, the projected costs surpassed $1 billion. For a few days in 2006, the International Astronomical Union considered giving the name "plutons" to large bodies in the outer part of the solar system, apparently thinking that it would signify "Pluto-like objects." 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. New Horizons had its closest approach to Pluto on 14 July 2015—after a 3,462-day journey across the Solar System. The stamps were unveiled in a ceremony at the Jet Propulsion Laboratory. Since the Houston workshop, Stern changed his mind to advocate instead for a Cassini-style orbiter that would use Charon's gravity to adjust its orbit while studying Pluto and its moons. A full list of previous and upcoming missions to the outer Solar System can be found at the List of missions to the outer planets article. Tras la convención que hubo en Praga, se dio una definición diferente para los planetas. Initial Funding Secured", "New Horizons, Not Quite to Jupiter, Makes First Pluto Sighting", "Happy Birthday Clyde Tombaugh: New Horizons Returns New Images of Pluto", "Help us put names on the maps of Pluto and Charon! Algunos científicos opinaban que Plutón se podía haber formado en cualquier otro punto del universo y había quedado atrapado en la órbita gravitatoria del Sol. Plutón [a] foi o deus do inframundo na mitoloxía romana.O seu equivalente na mitoloxía grega era Hades, aínda que Plutón era máis benigno.En canto á etimoloxía do nome confúndeselle coa de Pluto, o deus grego das riquezas.. Mito. In 1953, Charles B.  The series featured a stamp for all planets, displaying an image of the planet and highlighting an associated spacecraft which was sent to it. , However, Goldin later decided that Pluto Kuiper Express was of low importance, and thus cut funding to the project drastically. 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.  Described by Staehle as a "faster, better, [and] cheaper" approach than the Pluto 350 and Mariner Mark II projects, it caught the attention of then-NASA Administrator Daniel S. Goldin, who ordered all work on both Pluto 350 and Mariner Mark II to cease and shift all resources to the new Pluto Fast Flyby project instead.  That year, Staehle, with the help of JPL engineers and students from the California Institute of Technology, formed the Pluto Fast Flyby project. It appears that they need help from regional tectonics that pulls the crust apart—the same thing that favors volcanoes at the surface. It may also represent a magma chamber that never reached the surface, like Stone Mountain in Georgia. Iza Neptuna nije samo Pluton, već cijeli niz tijela vezanih u orbitalne rezonance s njim. Photographs of Pluto taken on 14 July 2015 taken 15 minutes after New Horizon's closest approach, from a distance of 18,000 kilometers and sent to Earth on 13 September 2015 show a near-sunset on Pluto with details of the surface and a haze in the atmosphere.
