Earthlings Can Finally Listen to Voyager Golden Record—for $98
In 1977 Carl Sagan and his team including Ann Druyan designed a record that would be taken into space by the Voyager project. The record was meant to last for a billion years, plated in gold. It was curated with the sounds of our earthly civilization, A mothers first words to her child, greetings in 59 different languages, whale sounds, beethoven, the list goes on. Thanks to Kickstarter, to celebrate the 40th anniversary of the Voyager, Ozma records has created playable replicas of the iconic album. You can pre-order this inspiring combination of science and art today.

40th Anniversary of Voyager
On September 5, 1977, Voyager 1 was launched on a mission to explore where nothing had flown before. First on its journey were Jupiter and Saturn and it is currently exploring interstellar space. Its twin spacecraft, Voyager 2, visited Uranus and Neptune and is now in the outermost layer of the heliosphere, called the heliosheath. Forty years later, both spacecraft continue to send back data and are searching for the heliopause, the region where the Sun’s influence wanes, which has never been reached by any spacecraft.This video is available for download from NASA's Image and Video Library: https://images.nasa.gov/#/details-NHQ_2017_0905_40th%20Anniversary%20of%20Voyager.html

NASA Beams a #MessageToVoyager
On Sept. 5, 2017—the 40th anniversary of Voyager 1’s launch—NASA revealed the winning #MessageToVoyager and beamed it into space. "Message to Voyager" is a social media campaign inspired by the messages of goodwill carried on the Golden Record aboard each Voyager spacecraft.NASA invited the public to submit short, uplifting messages to the Voyager 1 spacecraft and all that lies beyond it. These messages were a maximum of 60 characters and were tagged #MessageToVoyager. NASA tracked more than 30,000 submissions. The Voyager team together with JPL and NASA headquarters selected their 10 favorites, which were then put to a public vote. The winning message was sent into interstellar space by a command that originated from the Deep Space Network (DSN) mission control at NASA's Jet Propulsion Laboratory with help from the original Captain Kirk, actor William Shatner; Tracy Drain, Juno mission deputy chief engineer; Jeff Berner, DSN chief engineer; and Annabel Kennedy, DSN command engineer.To see all 10 finalist messages and get more details about the #MessageToVoyager campaign, visit https://voyager.jpl.nasa.gov/message/

Voyager 2 Trajectory through the Solar System
This visualization tracks the trajectory of the Voyager 2 spacecraft through the solar system. Launched on August 20, 1977, it was one of two spacecraft sent to visit the giant planets of the outer solar system. Like Voyager 1, Voyager 2 flew by Jupiter and Saturn, but the Voyager 2 mission was extended to fly by Uranus and Neptune before being directed out of the solar system.To fit the 40 year history of the mission into a short visualization, the pacing of time accelerates through most of the movie, starting at about 5 days per second at the beginning and speeding up to about 11 months per second after the planet flybys are past.The termination shock and heliopause are the 'boundaries' created when the plasma between the stars interacts with the plasma flowing outward from the Sun. They are represented with simple grid models and oriented so their 'nose' is pointed in the direction (Right Ascension = 17h 24m, declination = 17 degrees south) represented by more recent measurements from other missions.Credit: NASA's Scientific Visualization Studio

October 2017: Remembering Voyager 40 years later
This special issue focuses on Voyagers 1 and 2, including revealing Saturn's rings, the unsolved mysteries of the ice giants, The Grand Tour, and more!
In 1977, NASA's twin Voyager spacecraft embarked on an incredible journey to the outer planets and beyond. After delivering stunning images of Jupiter, Saturn, Uranus and Neptune, the probes sailed on to study the boundary of our heliosphere, the bubble that encompasses our sun, planets and solar wind. Voyager 1 crossed that frontier in August 2012, becoming the first human-made object in interstellar space, while Voyager 2 is expected to enter the space between the stars in the coming years.

Celebrating Voyager’s 40 Years in Space with Ed Stone
Ed Stone joined Caltech's faculty as an assistant professor of physics in 1967, and five years later was asked to helm the NASA mission that would become Voyager.Ed Stone was reluctant to take time from his teaching and research work at Caltech, but agreed to become project scientist for NASA’s Voyager mission, which explored the solar system before becoming the first mission to ever reach interstellar space.
As we celebrate the 40th anniversary of the launch of Voyager 1 and Voyager 2 spacecraft, Stone reflects on his work at Caltech and NASA's Jet Propulsion Laboratory, and on the breakthrough discoveries that inspired his team and future generations to explore the solar system and beyond.Read more: http://www.caltech.edu/news/voyager-spacecraft-celebrates-40-years-space-79391
Voyager 40th Anniversary: NASA's Voyager spacecraft still reaching for the stars - TomoNews
PASADENA, CALIFORNIA — NASA's Voyager 1 and 2 spacecraft are coming up on their 40-year anniversaries of exploration this August and September. The two spacecraft are still sending data back to Earth despite their vast distance, setting space exploration milestones.Voyager 1 and Voyager 2 spacecraft were launched in 1977 to take advantage of an alignment of Jupiter, Saturn, Uranus and Neptune that made it possible to use gravitational assists to explore the planets in a much shorter time. This alignment, discovered by Gary Flandro, who was a doctoral student at Caltech in 1965, appears once every 175 years.Voyager 2 was launched on August 20, 1977. It was the only spacecraft that conducted flybys of Jupiter, Saturn, Uranus and Neptune. Voyager 1 was launched on September 5, 1977. It took a shorter but faster trajectory that used a gravity assist at Saturn to take it out of the solar system. Each spacecraft carries a gold-plated record of Earth sounds, pictures and messages for any intelligent extraterrestrial life that might find them."None of us knew, when we launched 40 years ago, that anything would still be working, and continuing on this pioneering journey," Ed Stone, Voyager project scientist based at Caltech in Pasadena, California said in a press release. "The most exciting thing they find in the next five years is likely to be something that we didn't know was out there to be discovered."In 2012, Voyager 1 became the first spacecraft to cross into interstellar space. It is still transmitting data at a staggering distance of almost 13 billion miles away from Earth.Voyager 2 is in the space known as heliosheath, almost 11 million miles from Earth. It is expected to enter interstellar space in the next few years.

Chloe Cain - Instagram: @chloegwen2001Many people remember exactly where they were when humans first set foot on the Moon. But for those of us born after 1969, we’ve got to hang on to other epic moments in spaceflight history. I vividly remember watching the first launch of the space shuttle in 1981 when I was 9 years old, and I remember when NASA’s Voyager spacecraft swept past each of the outer giant planets in the Solar System: Jupiter, Saturn, Uranus and Neptune.It’s been nearly 40 years since the Voyagers blasted away from Earth, on their voyage into interstellar space, and here’s the most amazing part. They’re still operational. Still working hard to deliver us science, from the outer Solar System.As I record this video, Voyager 1 is the most distant object ever created by human beings, more than 20 billion kilometers away from Earth, more than 4 times the distance to Pluto. Here’s the really mind bending part. Voyager 1 is the farthest object we know of in the entire Solar System.But I’m getting ahead of myself, it’s time to look back, nearly 40 years and remember the Voyager missions and their amazing accomplishments over the decades.
Voyager - Uranus
After Voyager 2's successful Saturn encounter, it was shown that Voyager 2 would likely be able to fly on to Uranus with all instruments operating. NASA provided additional funding to continue operating the two spacecraft and authorized JPL to conduct a Uranus flyby. Subsequently, NASA also authorized the Neptune leg of the mission, which was renamed the Voyager Neptune Interstellar Mission. Voyager 2 encountered Uranus on January 24, 1986, returning detailed photos and other data on the planet, its moons, magnetic field and dark rings. Voyager 1, meanwhile, continues to press outward, conducting studies of interplanetary space. Eventually, its instruments may be the first of any spacecraft to sense the heliopause -- the boundary between the end of the Sun's magnetic influence and the beginning of interstellar space.

Pictures from Voyager
These pictures were taken from the Voyager spacecraft.Voyager explores the outer planets:
* Jupiter (Voyager 1/2, 1979)

* Neptune (Voyager 2, 1989)
10 Spacecraft That Have Travelled Farthest From Earth
Here are 10 spacecraft that have traveled extraordinary distances in the name of discovery.
The exploration of space has yielded many amazing and unexpected finds, and much of the credit goes to the vessels sent to the far reaches of the solar system and beyond.Here are 10 spacecraft that have traveled extraordinary distances in the name of discovery.Number 10. Mariner 4. This NASA craft was a Mars exploration superstar decades before rovers started roaming the Red Planet. During a 1965 flyby it captured the very first close-ups of the planet’s surface. Number 9. Rosetta. As if travelling to a distant, celestial body isn’t challenging enough, this one actually chased down a comet. Catching up with the speeding space rock took over a decade, but the ESA probe is now hanging out comfortably in its orbit. Number 8. Juno. Though launched back in 2011, Juno has a year to go before reaching Jupiter. There’ll be no time to rest upon arrival, as NASA has big plans. Those include circling the gas giant more than 30 times.Number 7. Galileo. This craft visited Jupiter and its moons back in mid 1990s. Using solar panels to harness and distribute energy wasn’t an option back then, so once it entered the Jovian system, Galileo was powered by plutonium.Number 6. Cassini. The probe is certainly a foremost expert on the topic of Saturn. Cassini completed its first 4-year mission in 2008 and, still up to the demands of exploration, embarked upon 2 more. Over the many years, the craft has gathered immense amounts of valuable information about the planet’s rings, moons, and environment. Number 5. New Horizons. A countless number of mishaps can happen on a roughly decade long, 3 billion mile journey but the NASA explorer managed to hold it together. Upon performing the recent close pass of Pluto, New Horizons gathered so many pictures and readings it’s going to take 16 months to send all the information to Earth. Number 4. Pioneer 11. Launched in 1973, the probe made it all the way the asteroid belt, whizzing by Jupiter and Saturn as well. What, if anything, Pioneer 11 has been up to lately is unknown, as NASA lost contact in 1995. Number 3. Pioneer 10. The craft was not only the first to encounter the asteroid belt but also went down in history for the unprecedented achievement of reaching solar system escape velocity. The transmitter on board finally lost power in 2003. At that point the probe was about 7-and-a-half billion miles from Earth. Number 2. Voyager 2. The long-time explorer was sent into space in 1977 and is still out there. At present, it’s about 10 billion miles from home.Number 1. Voyager 1. Launched shortly after Voyager 2, this Energizer Bunny of spacecraft remains on the move as well. In 38 years of travel it has rocketed past Jupiter and Saturn and entered interstellar space in 2012. At present, Voyager 1’s retirement is planned for 2025. Which space mission do you think is most extraordinary?
Voyager 2 Encounters Neptune and Triton 1989 NASA JPL
more at: http://scitech.quickfound.net/astro/planet_news.html"Highlights of Voyager 2's information gathering on the planet's upper atmosphere and orbiting arcs are shown, along with studies of Triton and its strange backward orbit.

https://en.wikipedia.org/wiki/Voyager_2Voyager 2 is a 722 kg (1,592 lb) space probe launched by NASA on August 20, 1977 to study the outer Solar System and eventually interstellar space. It was actually launched before Voyager 1, but Voyager 2 was sent on a different trajectory and arrived at Jupiter and Saturn after Voyager 1. Voyager 2 has been operating for 37 years, 11 months and 14 days as of 3 August 2015, and the Deep Space Network is still receiving its data transmissions.At a distance of 108 AU (1.62×1010 km) from the Sun as of April, 2015, it is one of the most distant man-made objects (along with Voyager 1, Pioneer 10 and Pioneer 11). Voyager 2 is part of the Voyager program with its identical sister craft Voyager 1, and is in extended mission, tasked with locating and studying the boundaries of the Solar System, including the Kuiper belt, the heliosphere, and interstellar space.The primary mission ended December 31, 1989, after encountering the Jovian system in 1979, Saturnian system in 1981, Uranian system in 1986, and the Neptunian system in 1989. It is still the only spacecraft to have visited the two outer giant planets Uranus and Neptune. The probe is now moving at a velocity of 15.4 km/s (about 55,470 km/hr) relative to the Sun, as of December, 2014...Encounter with NeptuneVoyager 2's closest approach to Neptune occurred on August 25, 1989. Because this was the last planet of the Solar System that Voyager 2 could visit, the Chief Project Scientist, his staff members, and the flight controllers decided to also perform a close fly-by of Triton, the larger of Neptune's two originally known moons, so as to gather as much information on Neptune and Triton as possible, regardless of Voyager 2's departure angle from the planet. This was just like the case of Voyager 1's encounters with Saturn and its massive moon Titan.Through repeated computerized test simulations of trajectories through the Neptunian system conducted in advance, flight controllers determined the best way to route Voyager 2 through the Neptune-Triton system. Since the plane of the orbit of Triton is tilted significantly with respect to the plane of the ecliptic, through mid-course corrections, Voyager 2 was directed into a path several thousand miles over the north pole of Neptune. At that time, Triton was behind and below (south of) Neptune (at an angle of about 25 degrees below the ecliptic), close to the apoapsis of its elliptical orbit. The gravitational pull of Neptune bent the trajectory of Voyager 2 down in the direction of Triton. In less than 24 hours, Voyager 2 traversed the distance between Neptune and Triton, and then observed Triton's northern hemisphere as it passed over its north pole.The net and final effect on the trajectory of Voyager 2 was to bend its trajectory south below the plane of the ecliptic by about 30 degrees. Voyager 2 is on this path permanently, and hence, it is exploring space south of the plane of the ecliptic, measuring magnetic fields, charged particles, etc., there, and sending the measurements back to the Earth via telemetry.While in the neighborhood of Neptune, Voyager 2 discovered the "Great Dark Spot", which has since disappeared, according to observations by the Hubble Space Telescope. Originally thought to be a large cloud itself, the "Great Dark Spot" was later hypothesized to be a hole in the visible cloud deck of Neptune.Neptune's atmosphere consists of hydrogen, helium, and methane. The methane in Neptune's upper atmosphere absorbs the red light from the Sun, but it reflects the blue light from the Sun back into space. This is why Neptune looks blue...
How Voyager 1 and 2 spacecrafts traversed our solar system.
http://voyager.jpl.nasa.gov/ Official NASA Website about NASA JPL Voyager Interstellar mission. Check it out!Have you ever wondered how is it that two small space crafts named Voyagers that #NASA launched in to space back in 1977 were able to traverse all across our solar system to see all those giant planets up close with unprecedented precision and control and return back amazing revelation about those unknown worlds? Well, hit the play button and let's go and ride along with them.Voyager missions were launched in 1977 for doing an initial reconnaissance mission of our planets in our solar system. Voyager 1 spacecraft went on to flyby giant planets like Jupiter and Saturn and then it went on to explore the unknown, in to the interstellar space. As of 2012, Voyager 1 is in the interstellar space. Voyager 2 Spacecraft went on to visit Jupiter and Saturn but in addition to that, it also went past Uranus and Neptune to give us the very first close up views of those unknown worlds. In-fact even now, those images returned by Voyager 2 are the only images that we have of those planets. Voyager 2 is also headed for interstellar space but it is very near to the region where our sun's presence ends and the interstellar medium ie. space between the stars, begins.
If you want to know more about the timeline of Voyager mission, check out this page: http://voyager.jpl.nasa.gov/mission/fastfacts.htmlVoyagers are continuing their mission in to realms that are outside our reach, even after 40 years of tireless service which shows how tough those two space crafts are. They are currently in a medium which is not the same as that from which they were made out of. They will continue to operate at-least for another decade when their power sources will dwindle leading to shutting down of instruments one by one until they can't be operated anymore. Afterwards, the voyagers will wander around the Milky-way galaxy like eternal wanderers, carrying some of the messages that we have put on them on a gold plated copper disk for any civilization that might recover them in the future. It shows the amount of human hope which those two spacecraft carry with them.Please share the story of these two amazing little spacecrafts if you think they are worthy of a few clicks of your mouse.
USA: VOYAGER SPACE PROBE REACHES 6.5 BILLION MILES FROM EARTH
English/NatThe space probe Voyager 1 has become the most distant man-made object from Earth.At 10:10 GMT on Tuesday, after 20 years of travel, Voyager 1 reached 6.5 billion (b) miles from earth - overtaking the previous record holder Pioneer 10.Scientists are looking forward to the next step of Voyager's trip, when it reaches the very end of the solar system and begins sending back information about interstellar space.Voyager 1 has served as an interplanetary photographer and messenger for the past 20 years.It sent back these computer-enhanced pictures of swirling clouds on Jupiter in 1980.On Tuesday Voyager 1 became the most distant man-made object from the Earth.In addition to sending back pictures, Voyager carries messages from earth with it - on board is a diagram of continental drift, DNA, and sheet music.Voyager 1 also carries a gold-plated record engraved with the sounds of a wild dog, a tractor, and spoken greetings in 55 languages.Scientists say the mission has been a great success from the very beginning.SOUNDBITE: (English)
"Today Voyager reached the milestone of 6.5 billion miles, making it the most distant, man-made object ever launched. That's 70 times further from the sun than the Earth is."
SUPER CAPTION: Dr. Edward Stone, Jet Propulsion Laboratory DirectorBoth Voyager 1 and Pioneer 10 are powered by nuclear batteries that will keep both space-craft running even as they continue to travel away from the sun.After passing Jupiter and Saturn, Voyager's trajectory was bent out of the plane in which most of the planets orbit the sun by the gravitational force of Saturn's moon Titan.Saturn is now headed to the edge of the solar system - scientists expect it will be passing into interstellar space within ten years.Any data it sends back would be the first information to come from the very edge of the galaxy.SOUNDBITE: (English)
"We've never had an object actually leave the solar system behind and enter into what's called interstellar space. We have some ideas as to what's out there, but this would be our first opportunity perhaps in the next decade or so to explore what's between the stars."
SUPER CAPTION: Dr. Edward Stone, Jet Propulsion Laboratory DirectorVoyager's signals now take nine and a half years to reach Earth and by the time they reach us their power is 20 (b)billion times weaker than the power of a digital watch battery.Voyager 1 was launched in September 1977.

Every few months, an eager new spacecraft arrives on the launch pad, ready for its date with destiny. If we don’t blow it all to bits with a launch vehicle failure, it’ll be gently placed into orbit with surgical precision. Then it’ll carry out a noble mission of exploring the Solar System, analyzing the Earth, or ensuring we have an infinite number of radio stations in our cars, allowing us to never be satisfied with any of them.Space is hostile. Not just to fragile hu-mans, but also to our anthropomorphized Number Five is alive robotic spacecraft which we uncaringly send to do our bidding. There are many hazards out there, eager to disrupt and dismantle our stalwart electronic companions. Oblivion feeds voraciously on our ever trusting space scouts and their tiny delicate robotic hearts, so many well before their time.How long have they got? How long will our spacecraft survive as we cast them on their suicide missions to “go look at stuff on behalf of the mighty human empire”? When spacecraft are hurled into the void, all mission planners know they’re living on borrowed time.The intrepid Mars Exploration Rovers, Spirit and Opportunity, were only expected to operate for 3 months. NASA’s Spitzer Space Telescope carried a tank of expendable helium coolant to let it see the dimmest objects in the infrared spectrum.Sometimes the spacecraft wear down for unexpected reasons, like electronic glitches, or parts wearing out. Hubble was equipped with rotating gyroscopes that eventually wore out over time, making it more difficult to steer at its targets, and only an intervention by rescue and repair allowed the mission to keep going.In general, a spacecraft is expected to last a few months to a few years. Spirit and Opportunity only had a planned mission of 3 months. It took Spirit more than 6 dauntless years to finally succumb to the hostile Martian environment. Opportunity is still kicking more than a decade later, thanks to some very careful driving and gusts of Martian wind clearing off its solar panels which didn’t surprise anybody.ESA’s Rosetta spacecraft needed to survive for 10 years in a dormant state before its encounter with Comet 67/P. It’s expected to last until the end of 2015. Then its orbit will carry it too far from the Sun to operate its solar panels, then it’ll go to sleep one last time.As a testament to luck and remarkable feats of engineering, some survive much longer than anyone ever expected. NASA’s Voyager Spacecraft, launched in 1977, are still going and communicating with Earth. It’s believed they’ll survive until 2025, when their radioisotope thermoelectric generators stop producing power.At which point they’ll return to the Earth at the heart of a massive alien spacecraft and scare the bejeebus out of us.… And I know what you’re thinking. Once our spacecraft stop functioning, they’ll still exist. Perhaps getting close enough to another source of solar energy to start transmitting again.So, how long will our spacecraft hold together in something roughly robot-probe shaped? Any spacecraft orbiting a planet or Moon won’t last long geologically before they’re given a rocky kiss of death with help from a big group hug from gravity.This might take a decade, a hundred years or a million. Eventually, that spacecraft is racing towards a well distributed grave on its new home.A spacecraft that’s orbiting the Sun should last much longer. However, a gravitational threesome with a planet or large asteroid could drag it into a solar death spiral or hurl it into a planet. There are asteroids whipping around from the formation of the Solar System, and they haven’t crashed into anything… yet.A lucky spacecraft might last hundreds of millions, or even billions of years. Our little robot friends that leave the gravitational pull of the Solar System have a chance of making it for the long haul.
Going to Pluto with New Horizons
New Horizons is just months from its close encounter with Pluto. It's history in the making!And I have to make a small correction. Talking to New Horizons PI Alan Stern, he pointed out that I misunderstood him about the spacecraft's post-Pluto plans. There are two Kuiper Belt Objects the spacecraft could reach, and the team will pick one based on ease of access (i.e. things like how to get there using a few consumables as possible) and from there will consider a possible next target. Still, one KBO or two, it's going to be awesome!Title image via NASA.

Uranus, its rings and Moons - Voyager 2
This five minute video is an edited version of a NASA Voyager documentary, with added segments on the planet and its moons and rings.
NASA's New Horizons Mission Continuing Voyager's Legacy of Exploration
NASA’s Mission to Pluto was a two part televised science event at NASA headquarters on August 25 – the same date that the agency’s New Horizons spacecraft passed the orbit of Neptune on its way to Pluto and exactly 25 years after the Voyager spacecraft’s encounter with Neptune in 1989. During the first event, entitled NASA’s New Horizons Pluto Mission: Continuing Voyager’s Legacy of Exploration, NASA scientists and officials discussed the two missions.
Sailing Past Neptune's Moon Triton
Sail past Neptune's moon Triton, with data obtained from NASA's Voyager 2 spacecraft in 1989. The historical footage has been restored and used to construct the best-ever global color map of the strange moon. The new Triton map has a resolution of 1,970 feet (600 meters) per pixel.The colors have been enhanced to bring out contrast but are a close approximation to Triton's natural colors. Voyager's "eyes" saw in colors slightly different from human eyes, and this map was produced using orange, green and blue filter images. In 1989, most of the northern hemisphere was in darkness and unseen by Voyager.Because of the speed of Voyager's visit and the slow rotation of Triton, only one hemisphere was seen clearly at close distance. The rest of the surface was either in darkness or seen as blurry markings.Download this video:
Voyager - Triton
NASA's Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989. Like an old film, Voyager’s historic footage of Triton has been 'restored' and used to construct the best-ever global color map of that strange moon. The map, produced by Paul Schenk, a scientist at the Lunar and Planetary Institute in Houston, has also been used to make a movie recreating that historic Voyager encounter, which took place 25 years ago, on August 25, 1989. The new Triton map has a resolution of 600 meters per pixel. The colors have been enhanced to bring out contrast but are a close approximation to Triton’s natural colors. Voyager’s 'eyes' saw in colors slightly different from human eyes, and this map was produced using orange, green and blue filter images. In 1989, most of the northern hemisphere was in darkness and unseen by Voyager. Because of the speed of Voyager's visit and the slow rotation of Triton, only one hemisphere was seen clearly at close distance. The rest of the surface was either in darkness or seen as blurry markings. The production of the new Triton map was inspired by anticipation of NASA's New Horizons encounter with Pluto, coming up a little under a year from now. Among the improvements on the map are updates to the accuracy of feature locations, sharpening of feature details by removing some of the blurring effects of the camera, and improved color processing. Although Triton is a moon of a planet and Pluto is a dwarf planet, Triton serves as a preview of sorts for the upcoming Pluto encounter. Although both bodies originated in the outer solar system, Triton was captured by Neptune and has undergone a radically different thermal history than Pluto. Tidal heating has likely melted the interior of Triton, producing the volcanoes, fractures and other geological features that Voyager saw on that bitterly cold, icy surface. Pluto is unlikely to be a copy of Triton, but some of the same types of features may be present. Triton is slightly larger than Pluto, has a very similar internal density and bulk composition, and has the same low-temperature volatiles frozen on its surface. The surface composition of both bodies includes carbon monoxide, carbon dioxide, methane and nitrogen ices. Voyager also discovered atmospheric plumes on Triton, making it one of the known active bodies in the outer solar system, along with objects such as Jupiter's moon Io and Saturn's moon Enceladus. Scientists will be looking at Pluto next year to see if it will join this list. They will also be looking to see how Pluto and Triton compare and contrast, and how their different histories have shaped the surfaces we see. Although a fast flyby, New Horizons' Pluto encounter on July 14, 2015, will not be a replay of Voyager but more of a sequel and a reboot, with a new and more technologically advanced spacecraft and, more importantly, a new cast of characters. Those characters are Pluto and its family of five known moons, all of which will be seen up close for the first time next summer. Triton may not be a perfect preview of coming attractions, but it serves as a prequel to the cosmic blockbuster expected when New Horizons arrives at Pluto next year.

Which Planets Have Rings?
You think only Saturn has rings? Well, think again. Rings are actually extremely common in our Solar System - they're all over the place. So which planets - and other objects - sport rings?
Solar Systems Largest Moon GANYMEDE of JUPITER Mapped by NASA. Can it Become HABITABLE
Solar Systems Largest Moon GANYMEDE of JUPITER Mapped by NASA. Can it Become HABITABLEThe largest moon in the solar system has finally received its cartographic due.Scientists have created the first global geological map of Jupiter's huge, ice-covered moon Ganymede, more than 400 years after its discovery by Galileo Galilei. The map, created using observations by NASA's twin Voyager probes and Galileo orbiter, highlights the varied terrain of Ganymede, which is bigger than the planet Mercury.To present the best information in a single view of Jupiter's moon Ganymede, a global image mosaic was assembled, incorporating the best available imagery from NASA's Voyager 1 and 2 spacecraft and NASA's Galileo spacecraft. This image shows Ganymede centered at 200 west longitude. This mosaic (right) served as the base map for the geologic map of Ganymede (left)."This map illustrates the incredible variety of geological features on Ganymede and helps to make order from the apparent chaos of its complex surface," Robert Pappalardo, of NASA's Jet Propulsion Laboratory in Pasadena, Calif., said in a statement. "This map is helping planetary scientists to decipher the evolution of this icy world and will aid in upcoming spacecraft observations." [Watch the video animation of the 1st full map of Jupiter's giant moon Ganymede]The new map, which was published by the U.S. Geological Survey (USGS), could also help scientists plan out the search for alien life, researchers said."After Mars, the interiors of icy satellites of Jupiter are considered the best candidates for habitable environments for life in our solar system," USGS Astrogeology Science Center director Laszlo Kestay said in a statement. "This geologic map will be the basis for many decisions by NASA and partners regarding future U.S. missions under consideration to explore these worlds."Observations of Jupiter's largest moon made since its discovery in 1610 have revealed many features and facts about Ganymede over the centuries. They show that the 3,273-mile-wide (5,268 kilometers) moon possesses dark, heavily cratered terrain as well as lighter, younger regions marked by many grooves and ridges.ganymedeA geologic map of Jupiter's largest moon Ganymede is superimposed over a global color mosaic of the Galilean moon made of images from NASA's Voyager 1, 2 and Galileo spacecraft.The moon's features have been shaped during three major geologic periods — one dominated by impact cratering, then another marked by lots of tectonic activity and finally a third in which this activity tapered off, scientists said."The highly detailed, colorful map confirmed a number of outstanding scientific hypotheses regarding Ganymede's geologic history, and also disproved others," said Baerbel Lucchitta, scientist emeritus at the USGS in Flagstaff, Ariz. "For example, the more detailed Galileo images showed that cryovolcanism, or the creation of volcanoes that erupt water and ice, is very rare on Ganymede."Voyager 1 and 2 flew by Ganymede in 1979 during their unprecedented solar system "grand tour," then kept on going all the way toward interstellar space (which Voyager 1 entered in August 2012). The Galileo probe studied Ganymede and many other members of the Jovian system while orbiting Jupiter from 1995 through 2003.You can download a high-resolution copy of the new Ganymede geologic map for free at the USGS website here: http://pubs.usgs.gov/sim/3237/
Carl Sagan, Ed Stone - Voyager Missions, 1990, Solar System Image & New Findings

Voyager Spacecraft detects Magnetic Bubbles At The Edge Of Our Solar System
NASA's two Voyager spacecraft show nothing's simple at the edges of the solar system.
After a three-decade journey away from Earth, the two Voyager spacecraft are approaching the outer edges of the solar system. To scientists' surprise, the satellites, launched in 1977, have revealed a region vastly different than previously modeled. The solar system's boundary is defined by a steady stream of particles known as the solar wind. The solar wind shoots out from the sun until it pushes up against the galactic medium and slows down at a line called the termination shock. Beyond this lies the heliosheath, where the solar wind's journey stops completely. Scientists thought the solar wind turned back smoothly at this point, sweeping back around the outskirts of the solar system. As seen in the video below, Voyager now shows that solar wind hits the heliosheath and piles up into a frothy layer filled with magnetic bubbles. This layer must have an affect on how intense energetic particles from the rest of the universe, called cosmic rays, make it into our solar system. But scientists have yet to figure out if the bubbles help stop the bulk of the rays, or are the prime factor that allows them to enter.Credit to: NASA Visualization Explorer / NASA's Goddard Space Flight Center/Conceptual Image Lab
Voyager Leaves the Solar System
Thirty-six years ago this month, on Sept. 5, 1977, the Voyager 1 spacecraft was launched from Cape Canaveral, Fla.On September 12, 2013, NASA officially confirmed that Voyager 1 had reached the interstellar medium in August 2012. This makes Voyager 1 the first spacecraft to exit our solar system, a mark in history to be remembered forever.Hear what today's leading Astro-celebs have to say about Voyager's incredible landmark accomplishment!
