Voyager Journey to the Stars

Voyager Journey to the Stars


They are part of an ancient quest. To push beyond our boundaries, to see what
lies beyond the horizon. Now tens of billions of kilometers from Earth,
two spacecraft are streaking out into
the void. What will we learn about the Galaxy, the Universe,
and ourselves from Voyager’s epic Journey to the stars? December 19, 1972. The splashdown of the Apollo
17 crew capsule marked the end of the golden age of manned spaceflight. The Mercury, Gemini, and Apollo programs had
proven that we could send people into space, to orbit the Earth, fly out beyond our planet,
then land on the moon and walk among its ancient craters. The collective will to send people beyond
our planet faded in times of economic uncertainty, war, and shifting priorities. And yet, just five years after Apollo ended,
scientists launched a new vision that was just as profound and even more far-reaching. We knew we were on a journey of discovery
when we launched the Voyager spacecraft, but we had no idea how much there was to discover. We had a sense that we knew what it felt like
to be Magellan or Columbus It didn’t all go smoothly. Early computer
problems threatened to doom Voyager 2. Then its radio receiver failed, forcing engineers
to use a back up. Now, after more than three and a half decades
of successful operations, the twin spacecraft are sending back information on their flight
into interstellar space. Along the way, they have revealed a solar
system rich beyond our imagining. Time after time we were surprised by seeing
things that we had not expected or even imagined: volcanoes erupting from the moon, Io, the
possibility of a liquid water ocean under the icy crust of Europa, Titan, where we found
an atmosphere, Uranus’ small moon, Miranda, which had one of the most complex geologic
surfaces we’ve seen. Even at Neptune, 40 degrees above absolute zero, even there, there
were geysers erupting. It’s the only spacecraft that has gone by
Uranus. It’s the only spacecraft that has gone by Neptune. Everything we know about
those planets, we know from Voyager. To see those first pictures coming in from
the outer solar system, for the first time, what had been a point of light in the sky
was a place. The journey was made possible by a rare alignment
of the planets, a configuration that occurs only once every 176 years. That enabled the craft to go from planet to
planet, accelerating as they entered the gravitational field of one, then flying out to the next. The Voyagers carried a battery of scientific
equipment to collect data on the unknown worlds in their path. That included a pair of vidicom
cameras, and a data transfer rate slower than a dialup modem. They are primitive by today’s standards,
but that didn’t stop them from returning a flurry of discoveries. On Jupiter’s moon
Io, Voyager’s cameras spotted nine erupting volcanoes. They documented volcanic plumes reaching 300
kilometers into the atmosphere, at velocities of one kilometer every second. Almost two years later, on November 12, 1980,
Voyager 1 sailed down to within 124,000 kilometers of Saturn’s cloud-tops. That’s one-third
the distance between Earth and the moon. It found that Saturn’s atmosphere is almost
entirely hydrogen and helium. It is the only planet in our solar system that is less dense
than water. One year earlier, Pioneer 11 had detected
a thick, gaseous atmosphere on Saturn’s large moon, Titan. Scientists decided to send
Voyager 1 to follow up. It sent back clues to one of the most fascinating
bodies in the solar system. Titan proved to be the only object in the
solar system, other than Earth, with stable bodies of surface liquid. Not water, but vast
lakes of liquid methane. Scientists could have chosen to send Voyager
1 out to Pluto. But Titan was more promising scientifically. But that meant its grand tour of the outer
planets was over. Voyager 1 headed north, above the plane of the solar system. Five years later, and over a billion and a
half kilometers beyond Saturn, Voyager 2 reached Uranus. Like all the other planets, Uranus spins like
a top. But Voyager 2 found that it’s actually tipped on its side. Its magnetic field reaches
out in a bizarre corkscrew tail, millions of kilometers into space. Voyager 2 discovered two new rings; thin,
dark bands of ice, rock, and dust with particles the size of a fist. Although the craft discovered 10 new Uranian
moons, the most eagerly anticipated event was a close encounter with Miranda, perhaps
the most bizarre object in our solar system. Close-ups revealed a strange and wondrous
landscape including a canyon 19 kilometers deep. Miranda may have collided with another moon,
shattered, and then by the force of its own gravity, slowly reassembled into this chunk
of rock and ice. After 12 years on the road, Voyager 2 now
sped toward its rendezvous with Neptune. The planet appears blue because methane in
its atmosphere absorbs most of the red in the light spectrum. Remarkably, Voyager 2 flew by Neptune only
35 kilometers off its charted course and only 1 second off its scheduled fly-by time. Skimming only 5,000 kilometers above the planet’s
north pole, Voyager found Neptune to be a giant ball of melted rock and ice. Cloaked
in hydrogen, helium, and methane gasses, its atmosphere is whipped by winds of 1,000 kilometers
per hour. Flying in closer than any spacecraft has come
to one of the outer planets, Voyager 2 discovered at least four complete rings of ice and rock,
six new moons, and a great dark spot; a hurricane the size of Earth raging in Neptune’s southern
hemisphere. The storm circles the planet every 18 hours,
and rotates around its own axis every 16 days. Oddly, the largest of Neptune’s 8 moons,
Triton, orbits in the opposite direction to the planet’s spin. Triton was likely an independent object in
orbit around the sun, until it was captured by Neptune’s gravity. Pocked with impact craters and glazed with
methane and nitrogen ice, Triton is the coldest known object in the Solar System, at minus
240 degrees Celsius. On its surface, scientists saw jagged mountains,
high cliffs, and frozen lakes. The most bizarre discovery was the presence
of icy geysers with plumes reaching 160 kilometers downwind. Leaving Neptune, Voyager 2 snapped one of
the most remarkable pictures ever taken. Neptune and its cold moon Triton, framed by
the dim light of the Sun. Several years earlier, the Pioneer spacecraft
carried a plaque illustrating the spin state of a hydrogen atom, a man and woman set against
an outline of the spacecraft, and the position of the Sun relative to 14 prominent pulsars. The Voyagers brought their own message in
a bottle: a disk encoded with images of life on Earth, greetings in 55 languages, a selection
of music, messages, and natural sounds. And here was this Noah’s Ark of human culture
that was being sent to the outer planets, and then beyond to wander in the interstellar
darkness for
a billion years. On Valentine’s Day 1990, Voyager 1 looked homeward. And what did it
find? Not the frame-filling Apollo Earth, but instead, that one-pixel Earth. That’s
here. That’s home. Thirteen years after launch, the Voyager craft
finally began their journey into the galaxy at large. They run on plutonium-powered Radioisotope
Thermoelectric Generators, a standard set up for NASA deep space missions. Because even
these systems don’t last forever, scientists have had to shut down Voyager’s instruments
one by one. Among the most valuable remaining sensors
are magnetometers that can read magnetic fields that constantly sculpt the outer solar system. This region is the outer edge of a bubble
formed by the sun’s magnetic field and the solar wind. Tonight we’re going to be getting the data
back from a magnetometer roll calibration maneuver, and that maneuver actually happened
on the Voyager 1 spacecraft over 16 hours ago, and the data is finally making it back
to the earth. What we’re doing is a roll about this high-gain antenna, and so if the
high-gain antenna here is pointed out toward earth we’re going to be rolling the spacecraft
along that high-gain antenna. That roll is done so that we can calibrate the instrument
so that we know what magnetic field belongs to the sun and what component belongs to the
actual spacecraft. They’re very near the edge of the bubble
the sun creates around itself called the Heliosphere. We’re getting very close to the boundary.
We don’t know how close because no spacecraft has ever been there before, but it could be
another few months, it could be another few years, but it’s probably not much longer
than that. We travel a billion miles every three years. You can’t see the bubble the sun creates
around itself because it’s invisible, but we can see an analog of it in a sink. If we
turn the water on very fast and look at the bottom of the sink, we see that near where
the water hits the bottom of the sink, it’s flowing very fast radially outward in all
directions, and getting thinner until it abruptly slows down in this thick region, and turns
around and flows down the drain. The two Voyager spacecraft are both in this thick region in
our heliosphere where the wind has slowed down and is starting to go down the tail of
the heliosphere. And eventually, in hopefully not too many more years, Voyager 1 will leave
this thick region and enter interstellar space. We have a 20-watt transmitter on the spacecraft
transmitting over 11 billion miles away, and so it comes in very slowly. But every bit
left that spacecraft over 16 hours ago and every bit is telling us something new that
we haven’t known before. As the solar wind travels out from the sun,
it pushes against the galactic medium and abruptly slows down in a region called the
Termination shock. Outside this is the Heliosheath, where the sun’s magnetic field is bent back
by the interstellar wind. The sun’s magnetic field spins in opposite
directions on the north and south poles, creating a sheet where the two spins meet. This sheet
gently ripples as it travels outward. When this sheet reaches the termination shock,
it starts to compress like water waves hitting a wall. The voyager spacecraft have now found that
these stacked up ripples of magnetic field form smaller bubbles, shown here as a computer
simulation. The discovery of this frothy character changes
our understanding of how extremely fast moving particles, called cosmic rays, enter our solar
system. When they arrive at this region, they slowly
move from bubble to bubble until they can reach smooth magnetic field lines and follow
them toward the sun. Recently, the twin Voyagers began their transition
into interstellar space. Voyager today is headed for the edge of interstellar
space. That’s the space between stars and it’s filled with material that has been
injected by the explosion of stars, matter which came from a particular direction, creating
a wind which has shaped the bubble in which the solar system is surrounded. Since July of 2012, the solar wind has decreased,
while the galactic wind has sped up. That places the craft in what scientists call
the “magnetic highway,” where the alignment of magnetic fields allows particles from the
sun to escape, and particles from the galaxy to pour in. When either one reports a complete change
in the direction of the magnetic field, that’s when scientists will know that it has finally
exited the solar system. Meanwhile, they are delivering a whole new
view of the galaxy in ultraviolet light. From Earth, this light is normally blocked by the
haze of particles at the edge of the solar system. Scientists are able to capture this light
from other galaxies because their wavelength has been shifted slightly by their journey
through space. Because ultraviolet light reveals the location
of vigorous star birth, it is providing a new window on the evolution of our galaxy. The Voyagers will keep sending back this and
other valuable data sets until their power begins to run out. They’ll finally go dead
around the year 2025. Voyager 2 will be heading south toward the
constellation Sagittarius. Travelling at 16 kilometers per second, it is expected to pass
4 light years from Sirius, the brightest star in the heavens, 290,000 years from now. Its twin will continue on a northward track
to a relatively empty region of our solar neighborhood. They will become silent emissaries from planet
earth, symbols of our boundless curiosity and aspiration. In the words of Carl Sagan: “These Spacecraft have taught us about the
wonders of other worlds, about the uniqueness and fragility of our own, about beginnings
and ends. They have given us access to most of the solar system, both in extent and in
mass. They are the ships that first explored what may be homelands of our remote descendants.” At the same time, Voyager’s journey into
the vast and forbidding oceans of interstellar space reminds us how closely our fate is tied
to our home planet. The twin craft will wander the galaxy undisturbed
for millions, even billions of years. They will endure long after everything man has
built has crumbled to dust. Compared to Voyager, we are living on borrowed
time, for mammalian species only last on average about a million years. Our ability to follow them into deep space
will take a new perspective on time and distance, beyond the short years and decades of human
activities. We’ll continue to track Voyager’s slow
but remarkable journey, while our civilizations and our planet change and evolve in the cosmic
blink of an eye.

    The voyager will not go on forever indefinitely, it will either be destroyed in interstellar space by space debris or be captured by and more advanced civilization and be taken apart to know its origins.

    our life is very limited maybe compare to the life of a fly. unless our brain could figure out how to travel way faster than the speed of light we have to wait to see if some alien discovers us.. some visitors to earth has discovered this speed but for what ever reason they can't communicate with us. time will tell….

    54 languages was a silly thing. It will be hard enough for any aliens to understand one language, so putting 53 others is just going to muddy the waters to the point that nothing makes sense to them. The whole thing is just going to be random noise to them.

    Also, the two images of humans will likewise mean nothing. Why would they even see those 2 dimensional images as 3 dimensional beings? They have no frame of reference. And as far as the audio on the record, how are they to play it, much less know it is there? Do we assume that aliens will have record players? Alien intelligence can come in any form. The only way that record is going to mean anything is if the alien intelligence is an exact copy of 1979 earth.

    So if the earth moves around 66,600mph and the sun moves around 45 to 50,000mph HOW THE FUCK DOES THE REST OF OUR SO CALLED SOLAR SYSTEM KEEP UP WITH THE MILKYWAY GALAXIE IF THAT IS MOVING AT 550,000mph??? And after you answer that then answer this one. Why hasn't our solar system collided with any other planets or solar systems? Why haven't we been back to the moon or gone to Mars yet? They been saying we're going to Mars since J.F.K. was in office. You sad fucking sheep you smh

    We've learned so much after only a few hundred years since Galileo. However, those years are only tiny, minute comparing to the history of the galaxies/earth/human race, etc. Let's wish the world would stay in harmony for a long long time so we can explore/learn/uncover much more surprises out there.

    It's almost incomprehensible (to our modern minds), is how in the world, NASA engineering at that time managed to place the Pioneer, and Voyagers 1 and 2 spacecrafts on their journeys with the extraordinary accuracy that all were accomplished with. What's more confounding is that the visual information from those planets, and other objects were sent at a rate of transmission that was "slower than the transmission rate" of the old dial-up phone modems of the early days of inter-computer communications of the early 1980s, and were received with such amazing clarity.

    When we finally have the technology to catch up to the voyagers should we let them continue as is, update their tech and let them continue on, or put them in a museum?
    I hope that future generation will have the intelligence to let them continue on as -is.
