In 1992, NASA's Jet Propulsion Laboratory (JPL) proposed the Pluto Fast Flyby mission. They also considered the term "plutinos." [14][15], In August 1992, Staehle telephoned Pluto's discoverer, Clyde Tombaugh, requesting permission to visit his planet. In early 2007 the craft made use of a gravity assist from Jupiter. There used to be a whole set of names for other pluton shapes, but they aren't really much use and have been abandoned. 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).[34]. [35][2] The concept describes an entrycraft that would brake using the drag of Pluto's thin but highly spread-out atmosphere. Hunt made fun of these in USGS Professional Paper 228 by proposing the name "cactolith" for a cactus-shaped pluton: "A cactolith is a quasihorizontal chonolith composed of anastomosing ductoliths whose distal ends curl like a harpolith, thin like a sphenolith, or bulge discordantly like an akmolith or ethmolith." Once on Pluto's surface, the vehicle would exploit Pluto's low gravity to hop between sites using propellant. Shortly after Voyager 2's flyby of Neptune and its findings at Triton in August 1989, scientists sought interest in a mission to Pluto and further studies for the existence of a Kuiper belt and Kuiper belt objects, potentially similar to Triton. 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. 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. 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. That is, plutons are defined by the presence of plutonic rocks. New Horizons captured its first (distant) images of Pluto in late September 2006, during a test of the Long Range Reconnaissance Imager.

Fuera del sistema solar. He works as a research guide for the U.S. Geological Survey. "Pluton" is a general term that covers the whole variety of shapes taken by bodies of magma. 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. 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). New Horizons also photographed the surfaces of Pluto and Charon. 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. Iza Neptuna nije samo Pluton, već cijeli niz tijela vezanih u orbitalne rezonance s njim. New Horizons had its closest approach to Pluto on 14 July 2015—after a 3,462-day journey across the Solar System. This is similar to NASA's Triton Hopper concept for exploring Neptune's largest moon Triton. [8][9], A Pluto orbiter/lander/sample return mission was proposed in 2003. A mushroom-shaped pluton may be called a lopolith, and a cylindrical one may be called a "bysmalith." Described as a "radical" mission concept, the mission would see two spacecraft being sent to Pluto. [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. Shallower intrusions may be called subvolcanic or hypabyssal intrusions. 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. There are a slew of partial synonyms based on a pluton's size and shape, including batholith, diapir, intrusion, laccolith, and stock. Exploring Pluto was contemplated since its discovery by Clyde Tombaugh in 1930 [citation needed], but Pluto presents significant challenges for exploration because of its small mass and great distance from Earth.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. 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. In the United States, the Idaho, Sierra Nevada, and Peninsular batholiths are the largest. [7], However, Goldin later decided that Pluto Kuiper Express was of low importance, and thus cut funding to the project drastically. [8] 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. 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! La Selección Colombia avergonzó al país, o al menos así lo indicaron los periodistas deportivos de más nombre en el territorio. [7], During the course of the late 1990s, a number of trans-Neptunian objects were discovered, confirming the existence of a Kuiper belt. [8] While both projects competed for approval, Pluto 350 was more favored by NASA mission planners, who were starting to adopt smaller missions such as Mars Pathfinder and NEAR Shoemaker. Pluto was rejected in favor of Titan, Uranus and Neptune. "I told him he was welcome to it", Tombaugh later remembered, "though he's got to go one long, cold trip". Alec Galeev, head of the Russian Space Research Institute, reached the agreement with Stern by stipulating that Russia would include an atmospheric probe that would impact Pluto after studying its atmosphere with a mass spectrometer. Dinamičari su bili presretni, počinjalo se vidjeti da su bili u pravu. The project was still too expensive, however, in the eyes of Administrator Goldin. As research and development into the mission progressed, the project's size, scope, and budget all expanded. 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. 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." 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. Es el más alejado del Sistema Solar. 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. [4][5] However, scientists decided that a flyby of Titan during the Saturn encounter would be a more important scientific objective. The two Voyager missions had the success criteria of just one of them reaching Saturn, which they far exceeded. [17] The proposal was forwarded to Administrator Goldin, but he vetoed the proposal, recommending instead that the JPL look into the feasibility of Pluto Fast Flyby being launched aboard a smaller rocket, such as the Delta II. The formation and fate of plutons is an important, long-standing scientific problem. Los astrónomos deberán seguir decidiendo su futuro. Sala je bila puna, i rijetko je tko htio propustiti priču u nastajanju. After a Neptune encounter, the alignment of Pluto made it impossible for Voyager 2 to continue there, leaving it on a trajectory out of the Solar System. 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. Planetas que no tienen una superficie bien definida, ya que están compuestos mayoritariamente por fluidos. Otherwise, it may take geophysical techniques to map the pluton's three-dimensional shape. [22] 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. Plutón es una bola helada de hielo y roca. 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.[20]. This project got delayed, and in 2000 the mission was cancelled, with NASA giving the reason of cost overruns. 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. [6] 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.

Se han descubierto muchos cuerpos en la misma región, comparte el espacio con otros cuerpos celestes. Camino a Marte. This can be easy to see in a pluton that was tilted so that erosion could cut through it at an angle. 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. [19] New Horizons was launched successfully on 19 January 2006. After an intense political battle, a revised mission to Pluto called New Horizons was granted funding from the US government in 2003. Internal divisions within NASA, including its Scientific Advisory Council, also voiced support for a Pluto mission. That stamp had been in so many presentations by that point, I knew it would please people to have it go along. [32] The probe could use electric propulsion similar to NASA's Dawn mission. Scientists to Push for Orbiter Mission". If New Horizons had travelled through such a ring system, there would have been an increased risk of potentially disabling micrometeoroid damage.[27]. A blister-shaped pluton that raised the overlying rocks into a dome may be called a laccolith. The idea was shortly scrapped, however, because of the infeasibility of miniaturizing scientific instruments aboard such a spacecraft to that size. 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. Muchos investigadores e integrantes de la sociedad civil no estuvieron de acuerdo con este nombramiento. Otros astrónomos opinaban que Plutón podría ser una luna de Neptuno. 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." Andrew Alden is a geologist based in Oakland, California. The stamp for Pluto, however, depicted a featureless sphere, presented with the phrase "not yet explored" in place of the name of a spacecraft. Then there are plutons that have no floor, or at least no evidence of one. One of the earliest concepts was for a 40-kilogram spacecraft that would reach Pluto in five to six years. 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. 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. Alan Stern would later cite that event as a significant factor towards the low enthusiasm for the Pluto Fast Flyby project. 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. [3][33] The report, written by principal investigator Stephanie Thomas of Princeton Satellite Systems, Inc., describes a Direct Fusion Drive (DFD) mission to Pluto. No los salvan ni los mayas . Exploring Pluto was contemplated since its discovery by Clyde Tombaugh in 1930[citation needed], but Pluto presents significant challenges for exploration because of its small mass and great distance from Earth. The Fusion-Enabled Pluto Orbiter and Lander was a 2017 phase I report funded by the NASA Innovative Advanced Concepts (NIAC) program. Camino a la Tierra. 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. 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. [16] That year, Staehle, with the help of JPL engineers and students from the California Institute of Technology, formed the Pluto Fast Flyby project. The next Pluto mission—an orbiter and lander? 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. [24] Between April and June 2015, New Horizons began returning images of Pluto that exceeded the quality that the Hubble Space Telescope could produce. [7] Because of growing budget constraints, the dual-spacecraft concept was scrapped in favor of sending a single spacecraft to Pluto. Durante muchos años se creyó de que Plutón era un satélite del planeta Neptuno. Scientific observations of Pluto began five months before the closest approach and continued for at least a month after the encounter. The weight of the spacecraft was raised again, this time to 175 kilograms, and NASA allowed further liberty with the project's budget. The stamps were unveiled in a ceremony at the Jet Propulsion Laboratory. [32] However, such a lander would only observe the Charon-facing hemisphere of Pluto, as Pluto and Charon are tidally locked. Su interior probablemente es similar al de otras lunas heladas del sistema solar. Other plutons have fatter shapes that have a roof and a floor. At the time of cancellation, the projected costs surpassed $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. Narrow sheets of magma that form sills and igneous dikes may qualify as plutons if the rock inside them solidified at depth. A pluton exposed at the Earth's surface has had its overlying rock removed by erosion. At that depth, the magma cooled and crystallized very slowly, allowing the mineral grains to grow large and tightly interlocked — typical of plutonic rocks. Pluto 350, however, would later become controversial among mission planners at NASA, who considered the project to be too small and too high-risk. Solar System → Local Interstellar Cloud → Local Bubble → Gould Belt → Orion Arm → Milky Way → Milky Way subgroup → Local Group → Local Sheet → Virgo Supercluster → Laniakea Supercluster → Observable universe → UniverseEach arrow (→) may be read as "within" or "part of". The last objective could be accomplished using infrared laser pulses. Who said geologists couldn't be funny? «De hecho, si pones a la Tierra donde está Plutón, ¡quedaría excluida!», le dijo Stern a CNN en 2015. [25][26], 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. 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. 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! 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. 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 (magma) several kilometers underground in the Earth's crust and then solidified. The group started a letter writing campaign which aimed to bring to attention Pluto as a viable target for exploration. 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. Aunque, quizás esta idea sea nuevamente cambiada en poco tiempo. - Upravo su mi telefonirali iz policije - objasni Miki ulazeći u auto - da je nekoliko divljih životinja pobeglo iz cirkusa. The Pluto Underground, Pluto 350 and Mariner Mark II, USPS postage stamp and "Pluto Fast Flyby", Kuiper belt, Pluto Kuiper Express and cancellation, Smithsonian National Postal Museum (date unknown). The mission was thus re-branded as the Pluto Kuiper Express, after briefly being billed as Pluto Express prior to the revision. [7], In October 1991, the United States Postal Service released a series of stamps commemorating NASA's exploration of the Solar System. [23] On 15 April 2015, Pluto was imaged showing a possible polar cap. 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. Geophysicists call such bodies diapirs ("DYE-a-peers"); salt domes are another example. Shortly after the New Horizons flyby, Stern suggested a Charon lander as a follow-up that would observe Pluto from Charon's surface. [12] 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. 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. [11] The series featured a stamp for all planets, displaying an image of the planet and highlighting an associated spacecraft which was sent to it. En nuestro Sistema Solar había nueve planetas anteriormente hasta que se redefinió lo que era o no un planeta y Plutón tuvo que salir de la conjunción de planetas. [9], In May 1989, a group of scientists and engineers, including Alan Stern and Fran Bagenal, formed an alliance called the "Pluto Underground". This became known as the Pluto Express, and eventually the Pluto-Kuiper Express. Los pequeños compañeros de Plutón [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.

Hasta 2006, el Sistema Solar contaba con un planeta más: Plutón. Plutón, el planeta olvidado que ya no es planeta. [30] 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.[31]. Incluso algunos siguen tratando de debatir este cambio, pero hasta el día de hoy Plutón sigue siendo un planeta enano. Power and propulsion would come from the bimodal MITEE nuclear reactor system.[18]. (See What Is a Planet?). 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. After Voyager 2 successfully returned data from Neptune in 1989, planetary scientists looked to Pluto as the destination for a subsequent mission. [8], 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. 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. Camino a Júpiter. Camino a Plutón. [28][29], No follow-up missions to New Horizons have been formally planned, but at least two mission concepts have been studied. For many years, people had waved that stamp around as sort of a call to arms, as a motivating graphic: "Not yet explored". Global Aerospace Corporation presented a Pluto lander concept titled "Pluto Hop, Skip, and Jump" at the 2017 NIAC Symposium in Denver, Colorado. Space Exploration Issue - 29c Pluto single - Scott Catalogue USA: 2577. Bottomless plutons like these are called stocks if they are smaller than 100 square kilometers in extent, and batholiths if they're larger. Early mission proposals. [10] 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. Thus plutons, and especially batholiths, go along with subduction zones that create arc volcanism. 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. [7] All four outer planets were explored by Voyager 2, launched in 1977, with close approaches to Jupiter, Saturn, Uranus, and Neptune. [21] The images, taken from a distance of approximately 4.2 billion kilometers, confirmed the spacecraft's ability to track distant targets, critical for maneuvering toward Pluto and other Kuiper belt objects.

[7], During the development of Pluto Fast Flyby, however, there were multiple concerns from both NASA, Administrator Goldin and the mission's development team. Plutón no es tan grande ni tan pequeño. Tras la convención que hubo en Praga, se dio una definición diferente para los planetas. 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. Ne indeamna sa fim distructivi, dar si de a aduce o reforma pozitiva si schimbari definitive. In 1953, Charles B. [1] There are no plans as yet for a follow-up mission, though follow-up concepts have been studied.[2][3]. It appears that they need help from regional tectonics that pulls the crust apart—the same thing that favors volcanoes at the surface.
