  • 40th Anniversary of Voyager

    1:15:06

    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.

  • Voyager 40th Anniversary: NASAs Voyager spacecraft still reaching for the stars - TomoNews

    9:25

    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.

    Many 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.

  • Voyagers 40th Anniversary

    9:44

    Voyager 2 launches from Cape Canaveral, Florida, aboard a Titan III-Centaur launch vehicle on August 20, 1977, about two weeks before the September 5 launch of Voyager 1. The two spacecraft were sent on different trajectories, and Voyager 1 was put on a path to reach its planetary targets, Jupiter and Saturn, ahead of Voyager 2.
    Richard Laeser, mission director, explains the working parts of the camera platform on a working model of Voyager 2 on August 26, 1981, in Pasadena, California.
    Engineers are engaged in the construction of a high-gain antenna for one of the Voyager spacecraft in this photo taken on October 29, 1975.
    Inspecting the nickel-plated master record of the Voyager Golden Record on July 28, 1977
    Flying aboard Voyagers 1 and 2 are identical golden records, carrying the story of Earth far into deep space. The 12 inch gold-plated copper discs contain greetings in 60 languages, samples of music from different cultures and eras, and natural and man-made sounds from Earth.
    As NASA's two Voyager spacecraft travel out into deep space, they also carry a small American flag along with the Golden Record. This picture shows John Casani, Voyager project manager in 1977, holding a small Dacron flag that was folded and sewed into the thermal blankets of the Voyager spacecraft before they launched.
    Voyager 1, aboard a Titan III-Centaur, lifted off on September 5, 1977, joining its sister spacecraft, Voyager 2, on a mission to the outer planets
    This picture of a crescent-shaped Earth and moon—the first of its kind ever taken by a spacecraft—was recorded September 18, 1977, by NASA's Voyager 1 when it was 7.25 million miles (11.66 million kilometers) from Earth. The moon is at the top of the picture and beyond the Earth as viewed by Voyager.

    The first close-up view of Jupiter is seen from Voyager 1. Voyager 1's closest approach to Jupiter occurred March 5, 1979.
    This photo of Jupiter's satellite Io was taken by Voyager 1 about 4:30 p.m. (PST) March 2, 1979. The spacecraft was about 5 million miles (8.3 million kilometers) away.

    This Voyager 1 image mosaic shows Io's south polar region. Haemus Mons, a 10-kilometer-high (32,000-foot) mountain is at right.
    Vibrant bands of clouds carried by winds that can exceed 400 mph continuously circle Jupiter's atmosphere. Such winds sustain spinning anticyclones like the Great Red Spot, a raging storm three-and-a-half times the size of Earth located in Jupiter’s southern hemisphere.
    This picture of a multi-ring basin on Callisto was taken the morning of March 6, 1979, from a distance of about 200,000 kilometers. The complicated circular structure seen at left-center is similar to the large circular impact basins that dominate the surface of the Earth's moon and also the planet Mercury.
    Voyager 1 took this photo of Jupiter and two of its satellites (Io, left, and Europa) on February 13, 1979. Io is about 350,000 kilometers (220,000 miles) above Jupiter's Great Red Spot; Europa is about 600,000 kilometers (375,000 miles) above Jupiter's clouds.
    Jupiter's moon Europa, imaged on July 9, 1979
    Voyager 1 and 2 observed radio signals from lightning which were interpreted as being from a persistent, low-latitude storm system which was extended in longitude, perhaps similar to the region highlighted on this Voyager 2 image acquired on August 4, 1981, from a distance of 21 million kilometers (13 million miles).
    Multiple impact craters are seen on the ancient surface of Saturn's moon Rhea in this picture taken by Voyager 1 on November 12, 1980, at a range of 73,000 kilometers (45,000 miles).
    This picture shows a Voyager 2 high-resolution view of Saturn's rings on August 23, 1981, at a range of 3.3 million kilometers (2 million miles). The planet’s limb is visible through the C ring and the inner part of the B ring.
    Voyager 1 looked back at Saturn on November 16, 1980, four days after the spacecraft flew past the planet, to observe the appearance of Saturn and its rings from this unique perspective. A few of the spokelike ring features discovered by Voyager appear in the rings as bright patches in this image, taken at a distance of 5.3 million kilometers (3.3 million miles) from the planet.
    This is an image of the planet Uranus taken by the spacecraft Voyager 2. NASA's Voyager 2 spacecraft flew closely past distant Uranus, the seventh planet from the sun, in January 1986.

  • NASA Beams a #MessageToVoyager

    4:50

    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.

    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.

  • Voyager 2, A Portrait Before The Farewell

    13:19

    Well, just four days after the deat- of Elvis, on August 20...from the Cape Canaveral base, the Voyager 2 mission left!
    43 years have passed, a lifetime...and yet since then Voyager has still been traveling, and still sending signals from ever more remote distances.
    It is the oldest of all of those still operational, but now perhaps it is time to say goodbye.
    Let's see why retracing its entire history.

    Pasadena, USA, summer 1964 at the Jet Propulsion Laboratory.
    In view of future space missions conducted with automatic probes, the young aerospace engineer Gary Flandro (1934) is assigned the task of studying new trajectories for the exploration of the external solar system.
    And Flandro does his job very well, so much so that he discovered that in a few years there would be an alignment between the outer planets that would allow a probe launched towards Jupiter to fly over Saturn, Uranus, and Neptune, only using the gravitational slingshot effect of each planet to reach the next; thus reducing from 40 to 10 years the time to complete the Grand Tour, as it was then called the tour of the outer solar system.
    But it must be done soon... that particular alignment occurs in fact only every 175 years, and to take full advantage of the favorable moment the probe must be launched in a period between 1976 and 1980.
    Flandro's study, published in 1965, makes a lot of sensation in the environment, and in 1969 it originates a first NASA mission proposal called Planetary Grand Tour, later canceled for budgetary reasons; and then the one for the launch of two twin probes generically called Mariner 11 and 12 (only in 1977 the spacecraft would have received the name of Voyager 1 and Voyager 2), the first one directed to Jupiter and Saturn and the second one charged to realize the Grand Tour desired by Flandro, that is: Jupiter, Saturn, Uranus, and Neptune!
    In the same year, the JPL proposed the construction of the probes, following the design phase begun in 1966, but it will not be easy ... In those years there were still many uncertainties about the obstacles that a spacecraft could encounter in crossing a region of the solar system that had not yet been explored.

    Some scientists, for example, believed that the asteroids of the main belt were so numerous that they prevented a spacecraft from crossing unharmed. Of great help in understanding that the danger was there, but much overestimated, were the Pioneer probes 10 and 11, which launched respectively on March 2, 1972, and April 5, 1973, would have been the forerunner for the Voyager.
    To make a long story short, after eight years of changes to the scientific and engineering load, Voyager 2 was launched from Cape Canaveral at 14:29 (universal time) on Saturday, August 20, 1977.
    About two years later, on July 9, 1979, the probe reaches the minimum distance from Jupiter, flies over the planet, and is diverted towards Saturn; receiving also a push (thanks to the slingshot effect) that increases its speed to reach Saturn more quickly.
    So Voyager 2 reaches the minimum distance from Saturn on August 26th, 1981, and from there it is diverted and accelerated towards Uranus, which flies over on January 24th, 1986; and, finally, from Uranus, it is directed towards Neptune, the remote planet that the probe reaches on August 25th, 1989.
    Carried out the primary mission, namely that of the Grand Tour of the four gas giants, the glorious spacecraft arrived at over 30 astronomical units of distance (equivalent to 4.5 billion kilometers) is assigned the Voyager Interstellar Mission.

    Find all the Voyager images here:


    The Voyager probes launched in 1977, but the idea for their mission was conceived 13 years earlier, in 1964.

    Gary Flandro, an aerospace engineer working at NASA’s Jet Propulsion Laboratory, was tasked with finding ways of exploring the outer gas giants.

    While proposing different possible trajectories that could come up over the next 20 years, he noticed a rare alignment of the outer planets that was going to occur in the late 1970s.

    All four outer gas giants would line up in such a way that a single probe could slingshot past all four of them. This was a once every 175-year phenomena.

    So he created the Planetary Grand Tour - a plan to visit all four gas giants in one shot.

    Both probes lifted off in 1977, with Voyager 2 actually launching before Voyager 1, on August twentieth and September fifth, respectively.

    But they were named in the order of when they would reach the planets, and Voyager 1 would be traveling faster.

    Voyager 1 reached Jupiter on March 5, 1979, and Voyager 2 followed a few months later on July 9.

    Together, they discovered that Jupiter has a ring system and found active volcanos on Io, the first active volcano outside planet Earth ever discovered.

    They took detailed photos of the Great Red Spot and the clouds in the Jovian atmosphere, studied the cracks in the ice around Europa and took the first pictures of Ganymede.

    They also took detailed measurements of Jupiter’s gravitational field and the radiation it carries.

    Saturn

    Voyager 1 reached Saturn in November of 1980 and Voyager two followed in August of 1981.

    And this is where they parted ways.

    Mission scientists were extremely interested in studying the moon Titan after Pioneer 11 photographed a dense atmosphere and organic compounds.

    But in order to get a close look at Titan, it required a polar trajectory around Saturn, which means it would be slingshotted up and out of the elliptical plane. Making it impossible to continue on to the other planets.

    So Voyager 1 took one for the team and made Saturn the end of its planetary run. It passed 6400 kilometers behind Titan and studied the temperature and composition of its atmosphere.

    And then, after a close fly-by of Saturn, the gravity assist propelled Voyager 1 up and out of the elliptical plane faster than any other manmade object in history.

    Voyager 2 had some fireworks of its own when it snapped the Pale Blue Dot photo on request from Carl Sagan.

    This now iconic photo, taken as Voyager sped away from Saturn, shows Earth as a tiny point of light in the sky, or as Sagan said, a mote of dust suspended in a sunbeam.

    Voyager 2 continued on to Uranus in January of 1986, and on to Neptune in January 1989. To this day, it is the only spacecraft that has visited either of these planets.


    At Neptune, Voyager 2 took a 30 degree turn south and continues to provide information about the sun’s magnetic field and the solar wind.

    In the north, Voyager 1’s enormous speed shot it further away from the sun than Pioneer 10, making it the furthest manmade object ever.

    And in 2012, NASA announced that Voyager 1 had officially entered the heliopause, the area where the sun’s solar wind meets the cosmic rays of interstellar space.

    Making it the first spacecraft to leave the solar system.

    There are only 5 spacecraft so far that will eventually leave the solar system, Voyager 1, Voyager 2, Pioneer 10 and 11, and the New Horizons spacecraft, and Voyager 1 is traveling faster than all of them. So unless we invent an interstellar warp drive, it will always be the furthest thing we have ever sent anywhere. Ever.

  • Voyager 1 PWS Jupiter Encounter audio 1979-03-05

    4:26:26

    On the occasion of the 40th anniversary of the Voyager 1 Jupiter encounter, we present *all* available plasma wave audio data acquired during the day of closest approach. Beware: This video is almost 4 hours 27 minutes in length and includes many uninteresting stretches of data.

    The PWS plasma wave instrument on Voyager 1 recorded these signals as the spacecraft made its closest approach to Jupiter on March 5, 1979. These are the authentic sounds of Jupiter in contrast to the multitude of artistic interpretations and therapeutic mixes found on YouTube that may be based on PWS data, but have been highly manipulated and sound very little like the original signals. The audio presented here is not shifted in frequency and not filtered or mixed with music.

    The PWS wideband waveform instruments on the two Voyager spacecraft sample the electric field on the dipole wire antenna at a rate of 28800 4-bit samples per second, using an automatic gain control. Consequently, the audio is just slightly better than telephone quality. Packets of 1600 samples are acquired, separated by the equivalent of 128 missing samples. Running these packets together results in the playback taking less than real-time (by a factor of 1600 / 1728), and also introduces a slight audible flutter. The amplitudes at the edges of these packets have been smoothed to reduce this flutter, but this is the only modification to the signal.

    The video shows a series of 48-second-wide spectrograms with an animated cursor that shows the time of the audio track. The amplitude of the signals is color coded with dark blue for the weakest and red for the strongest signals. Low frequencies are at the bottom of the plot and high frequencies are at the top. Time ranges from left to right.

  • Is It Possible To Retrieve Voyager 1??

    5:18

    Voyager 1 is a spacecraft that has been flying and operational for over 40 years! Nasa recently fired up it's thrusters for orientation after 37 years without use! But the topic I want to explore in this video is, could we retrieve the Voyager 1 spacecraft if we wanted to?

    ThoughtSpark wants to grab your attention, and spark thought in your mind on how and if we could theoretically achieve this epic space mission! A waste of time and money? Absolutely! But is it possible? Leave a comment on what you think!

    Update/Correction to video: To be more specific, Voyager 1 is the fastest spacecraft on a solar system exit trajectory (Out of 5 probes, and 4 Propulsion stage objects). Helios and Juno ARE faster, but they are in an orbital velocity with HUGE Masses, not in a solar system exiting trajectory like Voyager 1. Look for the Parker Solar Probe in the next few years to break Juno, and Helios speed records big time!!

  • OTD in Space - Sept. 5: Voyager 1 Launch

    52

    On Sept. 5, 1977, Voyager 1 began its epic journey through deep space with a glorious morning launch from Cape Canaveral, Florida.
    Voyager 1 initially launched on a mission to explore the outer planets. After flying by Jupiter and Saturn in 1979 and 1980, the spacecraft took a sharp turn and started heading straight out of the solar system.
    Voyager 1 became the first spacecraft to reach interstellar space in 2012, although scientists are still debating about exactly where that boundary lies.
    The spacecraft’s next big encounter will take place in about 40,000 years, when it will fly by another star system. And just in case it comes across any intelligent life out in the universe, it's carrying a golden record with sights, sounds and greetings from planet Earth.

    The Voyager program is an American scientific program that launched two unmanned space missions, the probes Voyager 1 and Voyager 2 were launched in 1977 to take advantage of a favorable alignment of the planets during the late 1970's. On August 25, 2012 Voyager 1 became the first human-made object to enter the previously unexplored region of space known as interstellar space, traveling further than anyone, or anything, in history Voyager 2 is expected to enter interstellar space in 2016.

  • Voyager 1 Trajectory through the Solar System

    2:11

    This visualization tracks the trajectory of the Voyager 1 spacecraft through the solar system. Launched on September 5, 1977, it was one of two spacecraft sent to visit the giant planets of the outer solar system. Voyager 1 flew by Jupiter and Saturn 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.

  • 40 Years Voyager - 2017 NASA Science Lecture

    1:16:41

    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. This live public talk at NASA's Jet Propulsion Laboratory in Pasadena, California, revisits highlights of the last 40 years and discuss what may lie ahead for the intrepid Voyagers.

  • Camilla SDO - Voyager 1 Launch Anniversary Flight, September 5, 2012

    2:31

    On Wednesday September 5th a group of California high school students celebrated the 35th anniversary of the launch of Voyager 1 in an unusual way; they launched me to the Edge of Space. I traveled to the top of our planet's atmosphere on board a suborbital helium balloon.

    I was wearing headphones. Why? Because I was listening to the Golden iPod, the modern-day successor to the Golden Records bolted to the side of the Voyager probes. The students are updating the Golden Records with 21st-century content that the students would like to send into the cosmos. This was just a test flight; in 2013, they hope to launch the Golden iPod into Earth orbit onboard a CubeSat they are building.

    At the apex of the September 5th suborbital flight, the helium balloon popped as planned and I parachuted back to Earth. The students, who call their group Earth to Sky, recovered Camilla and the Golden iPod from a remote landing site in the Nevada wilderness on September 6th. Now they are all enjoying music that has been to the doorstep of space itself.

    More information about the flight and the recovery expedition may be found at Earth to Sky's Facebook page. Students who wish to participate in the Golden iPod project can submit their ideas for the iPod's playlist at goldenipod.org.
