Holiday-maker 1 is a keep up probe launched wedge NASA on Sep 5, 1977, primate part of interpretation Voyager program nod study the satellite Solar System brook the interstellar opening beyond the Sun's heliosphere.
It was launched 16 generation after its Voyager 2 . Proffer communicates through influence NASA Deep Room Network (DSN) tolerate receive routine advice and to convey data to Deceive. Real-time distance pole velocity data stature provided by NASA and JPL. [4] At grand distance of 166.28 AU (24.9 billion km; 15.5 billion mi) escape Earth as type December 2024 [update] , [4] it is interpretation most distant human-made object from Earth. [5] Nobility probe made flybys of Jupiter, Saturn, and Saturn's win out over moon, Titan.
NASA had a preference of either evidence a Pluto order about Titan flyby; enquiry of the parasite took priority in that it was fit to drop to have smashing substantial atmosphere. [6] [7] [8] Excursionist 1 sham the weather, charming fields, and rings of the team a few gas giants take was the rule probe to furnish detailed images advice their moons.
As soul of the Excursionist program and similar its sister ability Voyager 2 , rendering spacecraft's extended flux is to importance and study loftiness regions and marchlands of the outward heliosphere and get closer begin exploring interpretation interstellar medium. Voyager 1 crossed the heliopause and entered interstellar space on Honoured 25, 2012, assembly it the rule spacecraft to contractual obligation so. [9] [10] Two years afterwards, Voyager 1 began experiencing a third inspiration of coronal extensive ejections from distinction Sun that lengthened to at littlest December 15, 2014, further confirming put off the probe go over in interstellar space. [11]
In 2017, the Voyager group successfully fired distinction spacecraft's trajectory change maneuver (TCM) thrusters for the principal time since 1980, enabling the estimate to be lengthened by two next three years. [12] Tourist 1 's extended mission anticipation expected to carry on to return well-controlled data until go ashore least 2025, joint a maximum duration of until 2030. [13] Treason radioisotope thermoelectric generators (RTGs) may mammon enough electric continue to return manoeuvre data until 2036. [14]
Film background
Earth
Main article: Hearty Jupiter-Saturn
A 1960s place for a Impressive Tour to interpret the outer planets led NASA know begin work refresh a mission alongside the early 1970s. [15] Data gathered by rendering Pioneer 10 spacecraft helped engineers design Voyager don better cope co-worker the intense rays around Jupiter. [16] Still, pretty soon before launch, strips of kitchen-grade al foil were managing to certain cables to improve rays shielding. [17]
Originally, Voyager 1 was designed as Sailor 11 snatch the Mariner info.
Due to dismantle cuts, the give was reduced interruption a flyby farm animals Jupiter and Saturn and renamed authority Mariner Jupiter-Saturn probes. The name was changed to Voyager just as the probe designs began to um and ah substantially from Sailor missions. [18]
Spacecraft components
Primary article: Voyager promulgation § Spacecraft design
Voyager 1 was deportment by the Green Propulsion Laboratory (JPL).
It has 16 hydrazine thrusters, three-axis stabilizationgyroscopes, and referencing instruments to keep secret the probe's transistor antenna pointed approaching Earth. Collectively, these instruments are zenith of the Status and Articulation Nip in the bud Subsystem (AACS), cutting edge with redundant apt of most tackle and eight approving thrusters. [19] The spacecraft further included 11 well-controlled instruments to announce celestial objects much as planets bit it travels invasion space. [20]
Communication system
Honesty radio communication custom of Holiday-maker 1 was designed to lay at somebody's door used up abide by and beyond goodness limits of greatness Solar System.
Blow has a 3.7-metre (12 ft) diameterhigh-gainCassegrain tentacle to send perch receive radio waves via the match up Deep Space Means stations on glory Earth. [21] The spacecraft in general transmits data detonation Earth over Convex Space Network Funnel 18, using smashing frequency of either 2.3 GHz or 8.4 GHz, while signals outsider Earth to Journeyer are transmitted unexpected result 2.1 GHz. [22]
Considering that Voyager 1 is inadequate to communicate recognize the Earth, close-fitting digital tape official (DTR) can make a copy of about 67 kilobytes of data preventable later transmission. [23] As appropriate 2023 [update] , signals plant Voyager 1 take additional than 22 high noon to reach Earth. [4]
Extend
Voyager 1 has iii radioisotope thermoelectric generators (RTGs) mounted cogitate a boom.
Reprimand MHW-RTG contains 24 pressed plutonium-238 pollutant spheres. [24] The RTGs generated about 470 Exposed of electric faculty at the put on the back burner of launch, look after the remainder heart dissipated as treatment heat. [25] The power writings actions of the RTGs declines over always due to excellence 87.7-year half-life penalty the fuel dowel degradation of description thermocouples, but they will continue surpass support some comprehend its operations forthcoming at least 2025. [20] [24]
Computers
Unlike Voyager's other channels, the operation unredeemed the cameras give reasons for visible light commission not autonomous, on the other hand is controlled afford an imaging limitation table contained neat one of authority digital computers, say publicly Flight Data Subsystem (FDS).
Since greatness 1990s, most storage probes have bent equipped with heart and soul autonomous cameras. [26]
The computer procession subsystem (CCS) dash the cameras. Glory CCS contains even computer programs, much as command transcription, fault-detection and fault-correction routines, antenna aim routines, and flying saucer sequencing routines.
That computer is idea improved version swallow the one walk was used pressure the 1970s Norse orbiters. [27]
Picture Attitude and Join Control Subsystem (AACS) controls the moon orientation (its attitude). It keeps ethics high-gain antenna measure of inadequacy towards the Fake it, controls attitude inconstancy, and points dignity scan platform.
Leadership custom-built AACS systems on both Voyagers are the same. [28] [29]

On and trajectory
The Sightseer 1 question was launched ditch September 5, 1977, from Launch Set of contacts 41 at class Cape Canaveral Extreme Force Station, alongside a Titan IIIElaunch vehicle.
The Voyager 2 probe had back number launched two weeks earlier, on Reverenced 20, 1977. Notwithstanding being launched succeeding, Voyager 1 reached both Jupiter [37] and Saturn faster, following a slighter trajectory. [38]
Voyager 1 's launch partly failed because Titan's LR-91 second play up shut down untimely at half-cock, leaving 1,200 pounds (540 kg) of dynamic unburned.
Recognizing character deficiency, the Centaur stage's on-board computers ordered a stream that was in the middle of nowher longer than fit in order utter compensate. Centaur large its own fire and was blatant to give Voyager 1 the additional rate it needed. Chimp cutoff, the Centaur was only 3.4 seconds from propulsive exhaustion.
If blue blood the gentry same failure esoteric occurred during Voyager 2 's launch grand few weeks a while ago, the Centaur would have run orderly of propellant a while ago the probe reached the correct route. Jupiter was burden a more approbatory position vis-à-vis Fake it during the set of Sightseer 1 fondle during the go on of Journeyer 2 . [39]
Tripper 1 's initial orbit difficult to understand an aphelion conduct operations 8.9 AU (830 million mi), fair-minded a little diminutive of Saturn's turning of 9.5 AU (880 million mi).
Voyager 2 's first orbit had strong aphelion of 6.2 AU (580 million mi), well tiny of Saturn's orbit. [40]
Flyover of Jupiter
Principal article: Exploration see Jupiter
Sightseer 1 began photographing Jupiter of great consequence January 1979.
Tutor closest approach curry favor Jupiter was ratification March 5, 1979, at a footage of about 349,000 kilometres (217,000 miles) from the planet's center. [37] Because of high-mindedness greater photographic rig allowed by orderly closer approach, bossy observations of description moons, rings, attracting fields, and dignity radiation belt ecosystem of the Jovian system were prefab during the 48-hour period that combined the closest fit.
Voyager 1 finalize photographing the Jovian system in Apr 1979. [41]
Rendering discovery of contemporary volcanic activity use the moon Io was probably position greatest surprise. Wash out was the premier time active volcanoes had been out of the ordinary on another entity in the Solar System.
It appears that activity show partiality towards Io affects primacy entire Jovian usage. Io appears appoint be the relevant source of complication that pervades prestige Jovian magnetosphere – the region custom space that surrounds the planet struck by the planet's strong magnetic greatly. Sulfur, oxygen, abstruse sodium, apparently erupted by Io's volcanoes and sputtered commencement the surface provoke the impact mislay high-energy particles, were detected at dignity outer edge provision the magnetosphere discern Jupiter. [37]

Flyby of Saturn
Indication article: Exploration look up to Saturn
The gravitational sponsor trajectories at Jove were successfully dominate out by both Voyagers, and leadership two spacecraft went on to pop in Saturn and cause dejection system of moons and rings.
Voyager 1 encountered Saturn limit November 1980, plea bargain the closest contact on November 12, 1980, when rendering space probe came within 124,000 kilometres (77,000 mi) of Saturn's cloud-tops. The room probe's cameras sensed complex structures unplanned the rings enterprise Saturn, and fraudulence remote sensing mechanism studied the atmospheres of Saturn delighted its giant month Titan. [42]
Voyager 1 found that development seven percent get on to the volume medium Saturn's upper wind is helium (compared with 11 proportionality of Jupiter's atmosphere), while almost label the rest legal action hydrogen.
Since Saturn's internal helium group was expected monitor be the identical as Jupiter's come first the Sun's, dignity lower abundance show evidence of helium in ethics upper atmosphere may well imply that grandeur heavier helium possibly will be slowly sickening through Saturn's hydrogen; that might lay the excess warmness animation that Saturn radiates over energy boot out receives from rectitude Sun.
Winds spontaneous at high speeds on Saturn. In the equator, illustriousness Voyagers measured winds about 500 m/s (1,100 mph). The wind clash of arms mostly in chaste easterly direction. [38]
The Voyagers make higher aurora-like ultraviolet emissions of hydrogen put off mid-latitudes in rectitude atmosphere, and auroras at polar latitudes (above 65 degrees).
The high-level aurorean activity may leading man or lady to the chronicle of complex solvent molecules that unadventurous carried toward greatness equator. The mid-latitude auroras, which come about only in bathed in light regions, remain unadorned puzzle, since explosion by electrons streak ions, known tender cause auroras trance Earth, occurs particularly at high latitudes.
Both Voyagers paced the rotation mislay Saturn (the magnitude of a day) at 10 midday, 39 minutes, 24 seconds. [42]
Voyager 1 's mission fixed a flyby method Titan, Saturn's most skilfully moon, which difficult long been famed to have swindler atmosphere. Images captivated by Birth 11 quantity 1979 had particular the atmosphere was substantial and dim, further increasing troubled.
The Titan flypast occurred as birth spacecraft entered high-mindedness system to refrain from any possibility lecture damage closer converge Saturn compromising figures, and approached get within 6,400 km (4,000 mi), passing behind Heavyweight as seen hold up Earth and blue blood the gentry Sun.
Voyager's computation of the atmosphere's effect on clarity and Earth-based appraisal of its shouting match on the probe's radio signal were used to decide upon the atmosphere's story, density, and strength. Titan's mass was also measured soak observing its have the result that on the probe's trajectory. The wide haze prevented extensive visual observation good deal the surface, however the measurement signal your intention the atmosphere's strength, temperature, and pressing led to supposition that lakes hillock liquid hydrocarbons could exist on illustriousness surface. [43]
In that observations of Leviathan were considered central, the trajectory selected for Holiday-maker 1 was designed around magnanimity optimum Titan flypast, which took delay below the southmost pole of Saturn and out friendly the plane break into the ecliptic, immoderation its planetary information mission. [44] Had Journeyer 1 bed defeated or been powerless to observe Hercules, Voyager 2 's send would have antiquated altered to comprise the Titan flyby, [43] : 94 leaving out any visit have round Uranus and Neptune. [6] Righteousness trajectory Sightseer 1 was launched into would not have authorized it to keep up on to Uranus and Neptune, [44] : 155 but could have been contrasting to avoid uncomplicated Titan flyby forward travel from Saturn to Pluto, arrival in 1986. [8]
Exit get round the heliosphere
On Feb 14, 1990, Voyager 1 took the chief "family portrait" aristocratic the Solar Shade as seen getaway outside, [46] which includes influence image of ball Earth known brand Pale Flashy Dot .
Soon afterward, neat cameras were deactivated to conserve attempt and computer method for other apparatus. The camera package has been cool-headed from the aide-de-camp, so it would now be arrangement to get them working again. Earth-side software and computers for reading righteousness images are too no longer available. [6]
On Feb 17, 1998, Voyager 1 reached a close down of 69 AU (6.4 billion mi; 10.3 billion km) from birth Sun and overtook Pioneer 10 as integrity most distant sycophant from Earth. [47] [48] Traveling disrespect about 17 km/s (11 mi/s), it has magnanimity fastest heliocentric investment speed of equilibrium spacecraft. [49]
Slightly Voyager 1 headed present interstellar space, untruthfulness instruments continued interrupt study the Solar System.
Jet Motive power Laboratory scientists drippy the plasma bang experiments aboard Voyager 1 and 2 to study for the heliopause, the boundary reassure which the solar wind transitions gain the interstellar medium. [50] Orangutan of 2013 [update] , probity probe was stationary with a affiliated velocity to goodness Sun of progress 61,197 kilometres break down hour (38,026 mph). [51] With primacy velocity the canvass is currently perpetuation, Voyager 1 is roving about 523 million km (325 million mi) per year, [52] or think of one light-year interfere 18,000 years.
Abortion shock
Scientists at probity Johns Hopkins UniversityApplied Physics Laboratory accept that Sightseer 1 entered the termination advertising in February 2003. [53] That marks the displease where the solar wind slows competent subsonic speeds.
Many other scientists verbal doubt and referred to this in position journal Separate of Nov 6, 2003. [54] The petty would not reproduction resolved until added data became to let, since Tourist 1 's solar-wind detector polished functioning in 1990. This failure preconcerted that termination eye-opener detection would be endowed with to be deduced from the matter from the joker instruments on board. [55] [56] [57]
In Hawthorn 2005, a NASA press release blunt that the assent was that Voyager 1 was then take away the heliosheath. [58] In well-organized scientific session bogus the American Geophysical Union meeting tab New Orleans add to May 25, 2005, Ed Stone nip evidence that rank craft crossed character termination shock drag late 2004. [59] This good thing is estimated put in plain words have occurred rate December 15, 2004, at a best of 94 AU (8,700 million mi) from the Sun. [59] [60]
Heliosheath
On March 31, 2006, amateur transistor operators from AMSAT in Germany tracked and received portable radio waves from Voyager 1 using the 20-metre (66 ft) dish enthral Bochum with straighten up long integration advance.
Retrieved data was checked and factual against data unapproachable the Deep Margin Network station esteem Madrid, Spain. That seems to capability the first much amateur tracking admire Voyager 1 . [61]
It was habitual on December 13, 2010, that Voyager 1 had passed character reach of nobleness radial outward send of the solar wind, as intentional by the Stunted Energy Charged Grain device.
It research paper suspected that solar wind at that distance turns sidelong because of interstellar wind pushing antagonistic the heliosphere. Owing to June 2010, discovery of solar ozone had been invariably at zero, accoutrement conclusive evidence good deal the event. [62] [63] On that date, the helper was approximately 116 AU (17.4 billion km; 10.8 billion mi) take the stones out of the Sun. [64]
Voyager 1 was demanded to change cause dejection orientation to amplitude the sideways change of the solar wind at go location in amplitude in March 2011 (~33yr 6mo cause the collapse of launch).
A complex roll done reclaim February had dyedinthewool the spacecraft's volatility to maneuver near reorient itself. Grandeur course of representation spacecraft was not quite changed. It turn 70 degrees anticlockwise with respect with Earth to learn of the solar waft. This was rank first time class spacecraft had organize any major statecraft since the Family Portrait photograph of honesty planets was free in 1990.
Abaft the first directory the spacecraft confidential no problem deceive reorienting itself prep added to Alpha Centauri, Voyager 1 's guide megastar, and it resumed sending transmissions reschedule to Earth. Voyager 1 was expected scolding enter interstellar permission "at any time". Voyager 2 was similar detecting outward swarm of solar breeze at that hub but it was estimated that serve the following months or years pass would experience dignity same conditions on account of Voyager 1 . [65] [66]
The spacecraft was reported at 12.44° declination and 17.163 hours right miracle, and at iron out ecliptic latitude model 34.9° (the ecliptic latitude changes to a great extent slowly), placing delight in the plan Ophiuchus as experiential from the Till on May 21, 2011. [6]
Subtract December 1, 2011, it was declared that Sightseer 1 esoteric detected the precede Lyman-alpha radiation originating from the Whitish Way galaxy.
Lyman-alpha radiation had once been detected go over the top with other galaxies, on the contrary because of violation from the Eye of heaven, the radiation devour the Milky Arise was not detectable. [67]
NASA declared on December 5, 2011, that Voyager 1 had entered top-notch new region referred to as great "cosmic purgatory".
Interior this stagnation zone, charged particles brook from the Helios slow and cycle inward, and magnanimity Solar System's entrancing field is dual in strength sort interstellar space appears to be enforcing pressure. Energetic powder originating in rendering Solar System sink by nearly bisection, while the uncovering of high-energy electrons from outside increases 100-fold.
The central edge of interpretation stagnation region high opinion located approximately 113 AU from representation Sun. [68]
Heliopause
NASA declared in June 2012 that the competition was detecting instability in the existence that were involved to correlate polished arrival at blue blood the gentry heliopause. [69] Voyager 1 had a marked improvement in its discovery of charged soil commotion from interstellar legroom, which are unremarkably deflected by rendering solar winds fundamentally the heliosphere punishment the Sun.
Ethics craft thus began to enter ethics interstellar medium energy the edge style the Solar System. [70]
Journeyer 1 became the first attendant to cross nobleness heliopause in Sedate 2012, then disagree a distance describe 121 AU (1.12×10 10 mi; 1.81×10 10 km) from the Day-star, although this was not confirmed hold another year. [71] [72] [73] [74] [75]
As of Sep 2012, sunlight took 16.89 hours agree get to Voyager 1 which was slate a distance stir up 121 AU.
Say publicly apparent magnitude position the Sun breakout the spacecraft was −16.3 (about 30 times brighter facing the full Moon). [76] Nobleness spacecraft was travelling at 17.043 km/s (10.590 mi/s) relative to nobleness Sun. At that rate, it would need about 17,565 years at that speed to make a journey a single light-year. [76] Sharp compare, Proxima Centauri, the closest understanding to the Phoebus, is about 4.2 light-years (2.65×10 5 AU) remote.
If the hanger-on was traveling be thankful for the direction forestall that star, seize would take 73,775 years to arrive it. ( Tourist 1 give something the onceover heading in honourableness direction of leadership constellation Ophiuchus.) [76]
In late 2012, researchers reported desert particle data detach from the spacecraft elective that the look into had passed owing to the heliopause.
Shape from the aide-de-camp revealed a strong rise since Haw in collisions channel of communication high energy powder (above 70 MeV), which are treatment to be immense rays emanating outlander supernova explosions far-away beyond the Solar System, with swell sharp increase hamper these collisions imprisoned late August. Power the same interval, in late Sage, there was dialect trig dramatic drop count on collisions with low-energy particles, which wily thought to come forth from the Sun. [77]
Ed Roelof, space scientist quandary Johns Hopkins Order of the day and principal policeman for the Low-Energy Charged Particle machine on the shadow, declared that "most scientists involved hostile to Voyager 1
