The use of a plutonium RTG battery was opposed by about 30 anti-nuclear protesters in minor demonstrations some days before launch. They are mounted on the face of the spacecraft and provide attitude information while in spinning or in 3-axis mode. [13], The Star 48B third stage is also on a hyperbolic Solar System escape trajectory, and reached Jupiter before the New Horizons spacecraft. new avenues. make the best out of a difficult situation ; turn sth negative into a positive. Because of the extreme distance from Pluto and the Kuiper belt, only one buffer load at those encounters can be saved. It is planned for New Horizons to fly within 10,000 km (6,200 mi) of Pluto in 2015. The downlink signal is amplified by dual redundant 12-watt TWTAs (traveling-wave tube amplifiers) mounted on the body under the dish. Because the population of KBOs appears quite large, multiple objects may qualify. [11] One of the trim weights on the spacecraft is a Florida state quarter. This entry is from Wikipedia, the leading user-contributed encyclopedia. Multiple clocks and timing routines are implemented in hardware and software to help prevent faults and downtime. Guo, Y.; Farquhar, R. W. (2005). The engines burned for 76 seconds, adjusting the spacecraft's velocity by about 1.16 meters per second. Search to look for new horizons and thousands of other words in English definition and synonym dictionary from Reverso. REX will perform radiometry of the nightside. [2] The spacecraft was at a declination of −21.44 degrees, and a right ascension of 18.483 hours at that time. Synonyms for horizons include field, expanse, length, breadth, extent, range, stretch, reach, scope and spread. It is expected, but not demanded, that most of these objectives will be met. when life gives you lemons, make lemonade! This equalizes temperature by radiative heat transfer. Also, the mass distribution required for a spinning spacecraft demands a wider triangle. The Jupiter encounter also served as a shakedown and dress rehearsal for the Pluto encounter. The moons' discoverers chose these names for this reason, in addition to Nix and Hydra's relationship to the mythological Pluto.[8]. The cost of the mission (including spacecraft and instrument development, launch vehicle, mission operations, data analysis, and education/public outreach) is approximately 650 million USD over 15 years (from 2001 to 2016). widen one's horizons. During the flyby, LORRI should be able to obtain select images with resolution as high as 50 m/px (if closest distance is around 10,000 km), and MVIC should obtain 4-color global dayside maps at 1.6 km resolution. new frontiers. phr. These objectives may be attempted, though they may be skipped in favor of the above objectives. [21], New Horizons' Long Range Reconnaissance Imager (LORRI) took its first photographs of Jupiter on September 4, 2006. A windows (pop-into) of information (full-content of Sensagent) triggered by double-clicking any word on your webpage. Uncompressed images will take about nine months[citation needed] to transmit, depending on Deep Space Network traffic. The high-gain dish has a Cassegrain layout, composite construction, and a 2.1 meter diameter (providing well over 40 dB of gain, and a half-power beam width of about a degree). Search for synonyms and antonyms. Even though it was launched far faster than any outward probe before it, New Horizons will never overtake Voyager 1 as the most distant man-made object from Earth. The rest of the time, the spacecraft will be in a slow spin, sending a beacon tone which will be checked once per week. It is also the first spacecraft launched directly into a solar escape trajectory, which requires an approximate velocity of 16.5 km/s (36,900 mph), plus losses, all to be provided by the launcher. The major part of this thrust is supplied by the Russian RD-180 engine, providing 4.152 MN (933,000 lbf). New Horizons has both spin-stabilized (cruise) and three-axis stabilized (science) modes, controlled entirely with hydrazine monopropellant. [UK];[Slang] Comes from cockney rhyming slang for "butcher's hook" = "look" - shows 3-letter terms; a? In the inner Solar System, the spacecraft must prevent overheating. This was the first launch of the 551 configuration of the Atlas V, as well as the first Atlas V launch with an additional third stage (Atlas V rockets usually do not have a third stage). term largely used in the 20's to describe women who acted contrary to what was commonly expected by going out, drinking, smoking, dancing, wearing make-up etc. It was still a white spot when Cassini flew by. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares. american. and '*': ??? In addition to the high-gain antenna, there are two low-gain antennas and a medium-gain dish. Special characters '?' 171.4%. Between star camera readings, knowledge is provided by dual redundant Miniature Inertial Measurement Unit (MIMU) from Honeywell. Each square carries a letter. View American English definition of broaden your horizons. The spacecraft trajectory coincidentally flew down the magnetotail for months. The Doppler shift will be measured by comparison with the ultrastable oscillator in the communications electronics. Then, when the spacecraft is cruising inactively in the cold outer Solar System, the louvers are closed, and the shunt regulator reroutes power to electric heaters. The primary encounter goals included Jovian cloud dynamics, which were greatly reduced from the Galileo observation program, and particle readings from the magnetotail of the Jovian magnetosphere. Total mass is 31 kg; rated power is 21 watts (though not all instruments operate simultaneously).[57]. Images were obtained through the Ralph telescope. Still, due to Pluto's tilt and rotation, a portion of the northern hemisphere will be in shadow at all times. Helium is used as a pressurant, with an elastomeric diaphragm assisting expulsion. Company Information Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. phr. You can also try the grid of 16 letters. Change your default dictionary to American English. Acta Astronautica 56 (3): 421–429. They are much improved over Galileo's cameras, which were evolved versions of Voyager cameras which, in turn, were evolved Mariner cameras. phr. Communication with the spacecraft is via X band. REX will perform active and passive radio science. One of the solid rocket boosters was hit by a door. Electronic activity is limited, power is diverted to shunts with attached radiators, and louvers are opened to radiate excess heat. The spacecraft carries two computer systems, the Command and Data Handling system and the Guidance and Control processor. To commemorate the discovery of Pluto, one ounce of the ashes of Pluto discoverer Clyde Tombaugh are aboard the spacecraft,[12] while one of the science packages (a dust counter) is named after Venetia Burney, who, as a child, suggested the name Pluto after its discovery. 3. new heights. Change the target language to find translations. M.M. ○   Anagrams The cameras determined their position, acting as "reverse optical navigation". phr. The processor used is the Mongoose-V, a 12 MHz radiation-hardened version of the MIPS R3000 CPU. "The New Horizons Distant Flyby of Asteroid 2002 JF56". The mission's principal investigator is Alan Stern (NASA Associate Administrator, formerly of the Southwest Research Institute). TCM-1 was accurate enough to permit the cancellation of TCM-2, the second of three originally scheduled corrections. Many subsystems and components have flight heritage from APL's CONTOUR spacecraft, which in turn had heritage from APL's TIMED spacecraft. However, it will not be the fastest spacecraft to leave the Solar System. Find out more, Computer-generated view from the spacecraft during flyby of. Coverage will repeat twice per day, to search for changes due to snows or cryovolcanism. Classic Thesaurus. The SensagentBox are offered by sensAgent. First day launch attempts scrubbed because of unacceptable weather conditions (high winds). [28] The available region, being fairly close to the plane of the Milky Way and thus difficult to survey for dim objects, is one that has not been well-covered by previous KBO search efforts. The aim point of the gravity-assist maneuver meant the spacecraft passed millions of kilometers from any of the Galilean moons. When life gives you lemons, make lemonade; but when life gives you melons, you might be dyslexic! The launch was delayed for further testing. RTG output is relatively predictable; load transients are handled by a capacitor bank and fast circuit breakers. The titanium fuel tank is in this tube. With a SensagentBox, visitors to your site can access reliable information on over 5 million pages provided by Past 55 AU, the communications link becomes too weak, and the RTG wattage will have decayed significantly enough to hinder observations. The flyby increased New Horizons' speed away from the Sun by nearly 4 km/s (8,900 mph), putting the spacecraft on a faster trajectory to Pluto, about 2.5 degrees out of the plane of the Earth's orbit (the "ecliptic"). C. open new horizons > synonyms. New Horizons reached Uranus's orbit at 22:00 GMT. No impact on the subsequent mission is expected.

[61][62][63], Other possible targets are Neptune trojans. In May 2006 it was discovered that New Horizons would pass close to the tiny asteroid 132524 APL on June 13, 2006. It was believed that a worst-case scenario of total dispersal of on-board plutonium would spread the equivalent radiation of 80% the average annual dosage in North America from background radiation over an area with a radius of 105 km (65 mi),[citation needed] at the Materials and Fuels Complex (formerly Argonne West), a part of the Idaho National Laboratory in Bingham County, near the town of Arco and the city of Idaho Falls. Unlike the Pioneers and Voyagers, the radio dish is also enclosed in blankets which extend to the body. Search to explore new horizons and thousands of other words in English definition and synonym dictionary from Reverso. [7] Pluto's newly-discovered 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". Subsequent to launch, the New Horizons team scanned the spacecraft's trajectory to determine if any asteroids would, by chance, be close enough for observation. consider, contemplate, examine, eye, eyeball, feast one's eyes upon, gaze, get a load of, regard, scan, scrutinize, see, study, survey, take a dekko at, appear, display, evidence, exhibit, look like, make clear, manifest, present, seem, seem to be, show, strike one as, face, front, front on, give onto, overlook, anticipate, await, expect, hope, reckon on, be the image of, favour, make one think of, put one in mind of, remind one of, resemble, take after, gaze, glance, glimpse, inspection, look-see, air, appearance, aspect, bearing, cast, complexion, countenance, demeanour, effect, expression, face, fashion, guise, manner, mien, attend to, care for, guard, keep an eye on, mind, nurse, protect, sit with, supervise, take care of, take charge of, tend, watch, contemn, despise, disdain, hold in contempt, look down one's nose at, misprize, scorn, sneer, spurn, treat with contempt, turn one's nose up (at), anticipate, await, count on, count the days until, expect, hope for, long for, look for, set one's heart on, wait for, check out, delve into, examine, explore, follow up, go into, inquire about, inspect, investigate, look over, make enquiries, make inquiries, probe, research, scrutinize, study, be alert, be careful, be on guard, be on the qui vive, be vigilant, beware, keep an eye out, keep one's eyes open, keep one's eyes peeled, keep one's eyes skinned, pay attention, watch out, flick through, inspect, look through, monitor, peruse, scan, take a dekko at, find, hunt for, research, search for, seek out, track down, ameliorate, come along, get better, improve, perk up, pick up, progress, shape up, admire, defer to, esteem, have a high opinion of, honour, regard highly, respect, revere, go to see, look in on, pay a visit to, visit, English Collins Dictionary - English synonyms & Thesaurus, Collaborative Dictionary     English Thesaurus.
