After launch, the New Horizons team scanned the spacecraft's trajectory to determine if any asteroids would, by chance, be close enough for observation. The communications dish on Earth measured the disappearance and reappearance of the radio occultation signal as the probe flew by behind Pluto. [105] Minor moons such as Amalthea had their orbit solutions refined. [148] Because of the extremely low RSL, it could only transmit data at 1 to 2 kilobits per second. Knowledge about Jupiter benefited from the fact that New Horizons' instruments were built using the latest technology, especially in the area of cameras, representing a significant improvement over Galileo's cameras, which were modified versions of Voyager cameras, which, in turn, were modified Mariner cameras. [42][43] A Florida-state quarter coin, whose design commemorates human exploration, is included, officially as a trim weight. [28] Each pellet is clad in iridium, then encased in a graphite shell. [66] These public images do not contain the full dynamic range of brightness information available from the raw LORRI images files. [1] Ralph has two major subinstruments, LEISA and MVIC. The other finalist, POSSE (Pluto and Outer Solar System Explorer), was a separate, but similar Pluto mission concept by the University of Colorado Boulder, led by principal investigator Larry W. Esposito, and supported by the JPL, Lockheed Martin and the University of California. The probe, about the size of a piano, weighed nearly 1,054 pounds at launch. After separation from the launch vehicle, overall control was taken by Mission Operations Center (MOC) at the Applied Physics Laboratory in Howard County, Maryland. [189], Science objectives of the flyby included characterizing the geology and morphology of Arrokoth[190][191] and mapping the surface composition (by searching for ammonia, carbon monoxide, methane, and water ice). After the spacecraft passed Arrokoth, the instruments continue to have enough power to be operational until the 2030s. Starting 3.2 days before the closest approach, long-range imaging included the mapping of Pluto and Charon to 40km (25mi) resolution.

[15] In August 2016, New Horizons was reported to have traveled at speeds of more than 84,000km/h (52,000mph). Its primary role is to determine the relative concentrations of various elements and isotopes in Pluto's atmosphere. The command and data handling software was updated to address the problem of computer resets.

The necessary course adjustment was performed with four engine firings between October 22 and November 4, 2015. After completing its famous flyby of dwarf planet Pluto in 2015,. [132] The object would be too distant to resolve surface features or take spectroscopy, but it would be able to make observations that cannot be made from Earth, namely a phase curve and a search for small moons. [24][25], The Ralph telescope, 75mm[72] in aperture, is one of two photographic instruments that make up New Horizons' Pluto Exploration Remote Sensing Investigation (PERSI), with the other being the Alice instrument. 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. Redundant components as well as guidance and control systems were shut down to extend their life cycle, decrease operation costs and free the Deep Space Network for other missions. The VBSDC is always turned on measuring the masses of the interplanetary and interstellar dust particles (in the range of nano- and picograms) as they collide with the PVDF panels mounted on the New Horizons spacecraft. It has seven instruments on board to . There are two redundant IEMs. New Horizons had a relative velocity of 13.78km/s (49,600km/h; 30,800mph) at its closest approach, and came as close as 28,800km (17,900mi) to Charon. 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. [19][20] In August 2018, NASA cited results by Alice on New Horizons to confirm the existence of a "hydrogen wall" at the outer edges of the Solar System. This Alice instrument is derived from another Alice aboard ESA's Rosetta spacecraft. [102] Callisto's surface was analyzed with LEISA, revealing how lighting and viewing conditions affect infrared spectrum readings of its surface water ice. Estimates for the dimensions of these bodies are: Nix at 49.833.231.1km (30.920.619.3mi); Hydra at 50.936.130.9km (31.622.419.2mi); Kerberos at 19109km (11.86.25.6mi); and Styx at 1698km (9.95.65.0mi). [134][135] On July 5, NASA announced that the problem was determined to be a timing flaw in a command sequence used to prepare the spacecraft for its flyby, and the spacecraft would resume scheduled science operations on July 7. Multiple redundant clocks and timing routines are implemented in hardware and software to help prevent faults and downtime. An objective to measure any magnetic field of Pluto was dropped, due to mass and budget issues associated with including a magnetometer on the spacecraft. During and after closest approach, SWAP and PEPSSI sampled the high atmosphere and its effects on the solar wind. The rated power is 21watts, though not all instruments operate simultaneously. The Radio Science Experiment (REX) used an ultrastable crystal oscillator (essentially a calibrated crystal in a miniature oven) and some additional electronics to conduct radio science investigations using the communications channels. The aft low-gain antenna is mounted within the launch adapter at the rear of the spacecraft. (Alice can perform similar occultations, using sunlight instead of radio beacons.) Infrared signatures of a further 36 volcanoes were noticed. Previous missions had the spacecraft transmit through the atmosphere, to Earth ("downlink"). [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. The first images of Pluto from New Horizons were acquired September 2124, 2006, during a test of LORRI. There are 16 thrusters on New Horizons: four 4.4N (1.0lbf) and twelve 0.9N (0.2lbf) plumbed into redundant branches. During the flyby, engineers expected LORRI to be able to obtain select images with resolution as high as 50m per pixel (160ft/px) if closest distance were around 12,500km, and MVIC was expected to obtain four-color global dayside maps at 1.6km (1mi) resolution. [180][181], Aside from its flyby of 486958 Arrokoth, the extended mission for New Horizons calls for the spacecraft to conduct observations of, and look for ring systems around, between 25 and 35 different KBOs. About 30 grams (1oz) of Clyde Tombaugh's ashes are aboard the spacecraft, to commemorate his discovery of Pluto in 1930. [130] Starting May 11 a hazard search was performed, looking for unknown objects that could be a danger to the spacecraft, such as rings or hithero undiscovered moons, which could then possibly be avoided by a course change. In terms of pure heliocentric velocity, the current champions are two probes called Helios I and II that were launched in 1974 and 1976. [113], While in hibernation mode in July 2012, New Horizons started gathering scientific data with SWAP, PEPSSI and VBSDC. Titanium provides strength and thermal isolation. [99] The images, taken from a distance of approximately 4.2billionkm (2.6billionmi; 28AU), confirmed the spacecraft's ability to track distant targets, critical for maneuvering toward Pluto and other Kuiper belt objects. 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. Weiler stated that it was a result that "[his] administration was not going to fight". No NASA spacecraft had ever launched with a nuclear-powered electrical source before.

[30], In November 2001, New Horizons was officially selected for funding as part of the New Frontiers program. [27] Alice Bowman became Mission Operations Manager (MOM).[32]. The craft had a communication rate of 38kbit/s at Jupiter; at Pluto's distance, a rate of approximately 1kbit/s per transmitter was expected. Mission managers estimated a one in 10,000 chance that debris could have destroyed the probe or its communication-systems during the flyby, preventing it from sending data to Earth.
