Funding was secured on July 1, 2016. Because there are two redundant communications subsystems, there are two, identical REX circuit boards. The cost of the mission (including spacecraft and instrument development, launch vehicle, mission operations, data analysis, and education/public outreach) is approximately $700 million over 15 years (2001–2016). Sometimes when fishing you’ll bring up Boots, Tires, or even Cans. [99] Recording from different angles and illumination conditions, New Horizons took detailed images of Jupiter's faint ring system, discovering debris left over from recent collisions within the rings or from other unexplained phenomena. Auf Io konnte ein Vulkanausbruch beobachtet werden. Am 8. [34] Pluto's satellites Nix and Hydra also have a connection with the spacecraft: the first letters of their names (N and H) are the initials of New Horizons. During the flyby, engineers expected LORRI to be able to obtain select images with resolution as high as 50 m per pixel (160 ft/px) if closest distance were around 12,500 km, and MVIC was expected to obtain four-color global dayside maps at 1.6 km (1 mi) resolution. Allerdings bestand nur bei einem Start bis einschließlich 2. Effective collecting area is 0.125 m2 (1.35 sq ft). Das DSN stellte zur Fehlerbehebung außerplanmäßig alle nötigen Ressourcen zur Kommunikation mit der Sonde zur Verfügung. Significantly, had the backup option been taken, this would have meant less fuel for later Kuiper belt operations. The structure is designed to act as shielding, reducing electronics errors caused by radiation from the RTG. Januar 2019 das Kuipergürtelobjekt (486958) Arrokoth (damals noch inoffiziell: Ultima Thule). The heat from the RTG adds warmth to the spacecraft while it is in the outer Solar System. These are the closest images taken of a Kuiper belt object besides Pluto and 486958 Arrokoth as of February 2018[update]. [31] Unter anderem die Gaia-Mission lieferte Daten zur Vorhersage von Sternbedeckungen. Es wurde mit der LORRI-Kamera erzeugt. Pioneer 11 (1973–1995) | Galileo (1989–2003) | Okkultationen gab es am 3. Sie führte in einer Entfernung von nur 3500 km an dem Asteroiden vorbei; dabei wurden alle Instrumente eingesetzt, die zuvor bei der Beobachtung Plutos verwendet worden waren. Januar 2006 und blieb bis zum 14. [27], 9. [15] On October 25, 2016, at 21:48 UTC, the last of the recorded data from the Pluto flyby was received from New Horizons. New Horizons (2006–) | Planmäßig flog die Sonde um 13:50 MESZ in 12.500 km Entfernung an Pluto und um 14:04 MESZ in 28.800 km Entfernung an Charon vorbei. New Horizons (englisch für Neue Horizonte) ist eine Raumsonde der NASA, die im Rahmen des New-Frontiers-Programmes am 19. Nach dem Jupiter-Vorbeiflug 2007 wurden sie zunächst nur noch einmal jährlich zu Testzwecken betrieben. Die beiden Kurskorrekturen ergaben eine Geschwindigkeitsänderung von 18 m/s. January 16, 2006: Rocket moved onto launch pad. Juli: Charon und Pluto, Aufnahme von New Horizons, 14. [116] Between July 19–24, 2014, New Horizons' LORRI snapped 12 images of Charon revolving around Pluto, covering almost one full rotation at distances ranging from about 429 to 422 million kilometers (267,000,000 to 262,000,000 mi). The detector contains fourteen polyvinylidene difluoride (PVDF) panels, twelve science and two reference, which generate voltage when impacted. New Horizons passed within 12,500 km (7,800 mi) of Pluto, with this closest approach on July 14, 2015, at 11:50 UTC. Ebenfalls im März wurde das SDC-Experiment aktiviert. Voyager 1 (1977–) | It is the fifth space probe to achieve the escape velocity needed to leave the Solar System. The exposure time was too short to see Pluto's smaller, much fainter, moons. New Horizons gehört zu den beliebtesten Marken in Deutschland und erhält die Auszeichnung NASA Pluto Probe to Fly by Another Object in 2019", "New Horizons Encore? The spacecraft's on-orbit mass including fuel is over 470 kg (1,040 lb) on the Jupiter flyby trajectory, but would have been only 445 kg (981 lb) for the backup direct flight option to Pluto. The rest of the triangle is primarily sandwich panels of thin aluminium facesheet (less than 1⁄64 in or 0.40 mm) bonded to aluminium honeycomb core. [56] The software of the probe runs on Nucleus RTOS operating system.[57]. [199] The majority of the science data was collected within 48 hours of the closest approach in a phase called the Inner Core. [6], Im Januar 2017 machte New Horizons eine Reihe von Aufnahmen vom Sternenhintergrund. Daraus konnten stereoskopische Bilder erzeugt werden.[62][63]. Besides the low data rate, Pluto's distance also causes a latency of about 4.5 hours (one-way). This Alice instrument is derived from another Alice aboard ESA's Rosetta spacecraft. Ende 2000 gab es mit New Horizons einen neuen Vorschlag einer Pluto-Mission. However, despite the large population of KBOs, many factors limited the number of possible targets. [63] In addition, New Horizons has an Ultrastable Oscillator subsystem, which may be used to study and test the Pioneer anomaly towards the end of the spacecraft's life. Die Flugzeit zu Pluto konnte damit gegenüber einer Flugbahn ohne Vorbeiflug an Jupiter um mehrere Jahre verkürzt werden. Predicted to take approximately 20 months. [141], Soon after the Pluto flyby, in July 2015, New Horizons reported that the spacecraft was healthy, its flight path was within the margins, and science data of the Pluto–Charon system had been recorded. Dieses führte zu einer Überlastung und Blockade des Computersystems, anschließend wurde automatisch auf das redundante B-Side-Computersystem umgeschaltet. To conserve heat and mass, spacecraft and instrument electronics are housed together in IEMs (integrated electronics modules). The downlink signal is amplified by dual redundant 12-watt traveling-wave tube amplifiers (TWTAs) mounted on the body under the dish. Heat-induced lightning strikes in the polar regions and "waves" that indicate violent storm activity were observed and measured. It is expected that the mission will be extended further if the spacecraft remains operational. The RTG provided 245.7 W of power at launch, and was predicted to drop approximately 3.5 W every year, decaying to 202 W by the time of its encounter with the Plutonian system in 2015 and will decay too far to power the transmitters in the 2030s.
