The spacecraft's on-orbit mass including fuel is over 470kg (1,040lb) on the Jupiter flyby trajectory, but would have been only 445kg (981lb) for the backup direct flight option to Pluto.

Of all the missions we've ever launched into space, only five probes will leave the Solar System: Pioneer 10 and 11, Voyager 1 and 2, and New Horizons. It also observed Neptune's largest moon Triton (a captured KBO) in 2019. The command and data handling software was updated to address the problem of computer resets. (CNN: UNITED LAUNCH ALLIANCE, NASA, MARS ONE) As of January 2019, the power output of the RTG is about 190W.[52]. After the spacecraft passed Arrokoth, the instruments continue to have enough power to be operational until the 2030s. SWAP measures particles of up to 6.5keV and, because of the tenuous solar wind at Pluto's distance, the instrument is designed with the largest aperture of any such instrument ever flown. ET on . The titanium fuel tank is in this tube. [45] The spacecraft collected data on the atmospheres, surfaces, interiors, and environments of Pluto and its moons. New Horizons is an interplanetary space probe that was launched as a part of NASA's New Frontiers program. The RTG provided 245.7W of power at launch, and was predicted to drop approximately 3.5W every year, decaying to 202W by the time of its encounter with the Plutonian system in 2015 and will decay too far to power the transmitters in the 2030s. New Horizons is the first mission in NASA's New Frontiers mission category, larger and more expensive than the Discovery missions but smaller than the missions of the Flagship Program. These were the closest images taken of a Kuiper belt object besides Pluto and Arrokoth as of February2018[update]. NewHorizons Launch Date: 2006-01-19 Launch Vehicle: Atlas V Launch Site: Cape Canaveral, United States Mass: 385 kg Personnel Selected References Stern, A., and J. Spencer, New horizons: The first reconnaissance mission mission to bodies in the Kuiper Belt, Earth, Moon, Planets, 92, 477-482, 2003. [92], On April 7, 2006, the spacecraft passed the orbit of Mars, moving at roughly 21km/s (76,000km/h; 47,000mph) away from the Sun at a solar distance of 243 million kilometers.[93][94][95]. The larger thrusters are used primarily for trajectory corrections, and the small ones (previously used on Cassini and the Voyager spacecraft) are used primarily for attitude control and spinup/spindown maneuvers. New Horizons Jul 14, 2015 RELEASE 15-149 NASA's Three-Billion-Mile Journey to Pluto Reaches Historic Encounter Pluto nearly fills the frame in this image from the Long Range Reconnaissance Imager (LORRI) aboard NASA's New Horizons spacecraft, taken on July 13, 2015 when the spacecraft was 476,000 miles (768,000 kilometers) from the surface. New Horizons' body forms a triangle, almost 0.76m (2.5ft) thick. Where is New Horizons? Ralph is a science instrument aboard the robotic New Horizons spacecraft, which was launched in 2006. The "secondary objectives" were expected to be met but were not demanded. [183] This KBO was again imaged by the LORRI instrument on April 78, 2016, from a distance of 111millionkm (69millionmi; 0.74AU). The Naval Observatory itself is not far from the Lowell Observatory where Pluto was discovered.

New Horizons, U.S. space probe that flew by the dwarf planet Pluto and its largest moon, Charon, in July 2015. Each unit contains three solid-state gyroscopes and three accelerometers. [56], The spacecraft carries two computer systems: the Command and Data Handling system and the Guidance and Control processor. [127][128] New Horizons was more than 203million kilometers (126,000,000mi) away from Pluto when it began taking the photos, which showed Pluto and its largest moon, Charon. The asteroid was imaged by Ralph (use of LORRI was not possible because of proximity to the Sun), which gave the team a chance to test Ralph's capabilities, and make observations of the asteroid's composition as well as light and phase curves. Weiler stated that it was a result that "[his] administration was not going to fight". The Cassini launch had been protested by multiple organizations, due to the risk of such a large amount of plutonium being released into the atmosphere in case of an accident. [citation needed], In 2011, mission scientists started the New Horizons KBO Search, a dedicated survey for suitable KBOs using ground telescopes. VBSDC searched for dust, inferring meteoroid collision rates and any invisible rings. [27] New Horizons was based largely on Stern's work since Pluto 350 and involved most of the team from Pluto Kuiper Express. On April 17, 2021, the New Horizons spacecraft passed 50 astronomical units - 50 times Earth's distance from the sun - while speeding toward interstellar space. This "wall" was first detected in 1992 by the two Voyager spacecraft.[24][25]. [144], Initial predictions envisioned Kerberos as a relatively large and massive object whose dark surface led to it having a faint reflection. There are 16 thrusters on New Horizons: four 4.4N (1.0lbf) and twelve 0.9N (0.2lbf) plumbed into redundant branches. The downlink signal is amplified by dual redundant 12-watt traveling-wave tube amplifiers (TWTAs) mounted on the body under the dish. It was in 2006 when the New Horizons spacecraft was launched by NASA with the aim of performing the closest flyby of Pluto. [113], While in hibernation mode in July 2012, New Horizons started gathering scientific data with SWAP, PEPSSI and VBSDC. [175] A course change to reach it required about 35% of New Horizons' available trajectory-adjustment fuel supply. [150] The transfer was completed on October 25, 2016, at 21:48UTC, when the last piece of datapart of a PlutoCharon observation sequence by the Ralph/LEISA imagerwas received by the Johns Hopkins University Applied Physics Laboratory. Two star cameras are used to measure the spacecraft attitude. This antenna was used only for early mission phases near Earth, just after launch and for emergencies if the spacecraft had lost attitude control. Overall mass is 8.6kg (19lb), with the optical tube assembly (OTA) weighing about 5.6kg (12lb),[67] for one of the largest silicon-carbide telescopes flown at the time (now surpassed by Herschel). For other uses, see, Pluto's Charon-facing opposing hemisphere viewed on July 11, 2015, Distant view of Cape Canaveral during the launch of, Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI), Venetia Burney Student Dust Counter (VBSDC), In-flight tests and crossing of Mars orbit. NASA's New Horizons spacecraft, launched in January 2006, is the one best suited to measure them. The probability that a target for New Horizons would be found was estimated beforehand at about 95%.[168]. (The Pioneers have hexagonal bodies, whereas the Voyagers, Galileo, and CassiniHuygens have decagonal, hollow bodies.) In May 2006 it was discovered that New Horizons would pass close to the tiny asteroid 132524 APL on June 13, 2006. [192] Confirmation that the craft had succeeded in filling its digital recorders occurred when data arrived on Earth ten hours later, at 15:29 UTC. [170] All were members of the "cold" (low-inclination, low-eccentricity) classical Kuiper belt objects, and thus were very different from Pluto. Now five years past its rendezvous with Pluto, where it captured the first up-close images of the dwarf planet, today it ventures through the Kuiper belt at the edge of our solar system where pickup ions are the freshest. A 7075 aluminium alloy tube forms the main structural column, between the launch vehicle adapter ring at the "rear", and the 2.1m (6ft 11in) radio dish antenna affixed to the "front" flat side.
