10 historical moments “Voyager 1” on the way to interstellar space
The mission of “Voyager 1” was very long and lasts for 36 years
The other day space agency NASA announced that in August 2012 the spacecraft “Voyager 1” opened new horizons for humanity: the interstellar space. The most distant from us a man-made space object is in a region filled with plasma (very hot gas), which has a higher density than the sun.
The spacecraft is at a distance of almost 19 billion miles away from home, and for its 36-year history had a lot to see and learn about the planets and moons of the solar system. Below you can see the ten most probably significant historical moments in his journey.
10. Starting: September 5, 1977
The launch is “Voyager 1” occurred September 5, 1977 at Kennedy Space Center
Running “Voyadrzhera-1” occurred from Cape Canaveral Sept. 5, 1977. His twin “Voyager 2”, interestingly, was launched from Earth for 16 days before – 20 August of the same year. Each of the spacecraft carries a lot of different tools for research, as well as a gold record with sounds of Earth and plate with diagrams, which is the location of our planet.
9. Earth and moon in a single frame
After about two weeks since launch, September 18, 1977, “Voyager 1” has made three images of the Earth and the Moon, which were later collected in a single photo. Moon made it brighter, so you can see it in more detail. It was the first time in history when a single photo and hit the Earth, the Moon, say in NASA.
8. The pale blue dot
This is us!
February 14, 1990, “Voyager 1” is at a distance of about 6 billion kilometers from Earth. Command Center has submitted a request to the spacecraft, so that he turned in our direction and made pictures of planets in the solar system. Among these photographs was the famous “blue dot”. Our Earth.
“Take another look at this pale blue dot. Over there. This is our home. That’s us! “- Wrote in 1997, astronomer Carl Sagan in his book.
7. Saturn’s moon on the background of his f-ring
Prometheus, a small kartofeleobraznaya moon of Saturn, captured this week “Voyager 1” on the background f-rings of the planet
“Voyager 1” found Prometheus and Pandora – two moons of Saturn, which hold the f-ring gas giant to more remote from the general education of the Rings distance. Earlier this year, scientists found that Saturn’s rings are very interesting feature – they are rains that fall on the planet.
6. On the satellites of Saturn have water

After many years of study of Saturn’s moons just as small points of light, “Voyager 1” managed to miss a few of them: Dione, Enceladus, Mimas, Rhea, Tethys and Titan. Most of these moons, surprisingly scientists were covered with ice, which put into question the earlier assumption that the water in the solar system is extremely rare. Thanks to the “Voyager 1” now that we know about these celestial bodies is greater than ever before.
5. The orange haze of Titan
Titan – one of Saturn’s moons, covered with a thick layer of orange haze
“Voyager 1” makes the photo, which is then the next few decades plagued the minds of astronomers from around the world. What lies beneath the mysterious haze of Titan, one of Saturn’s moons? The issue is so bites into the heads of scientists, the European Space Agency is sending a space probe to the moon, “Huygens”, which in 2005, carries out a successful landing on the satellite.
4. Detection of Active Volcanoes on Io
In this photo made ”Voyager 1″, see the active volcanoes (dark spots) Io
The discovery of “Vodyazhera-1” showed us that the solar system rich in a variety of exciting planetary satellites. For example, on Io, the closest satellite of Jupiter, as it turns out, is constantly evolving volcanic activity.
3. “Voyager 1”, – the most distant from the Earth man-made space object
In 2013, developed a computer model of the situation, “Voyager 1” in the solar system, along with the positions of “Voyager 2”, as well as satellites, “Pioneer 10” and “Pioneer 11”.
February 17, 1998, “Voyager 1” is the furthest from the Earth man-made space objects, overtaking another very remote from our planet probe – spacecraft “Pioneer 10”.
2. Rushing to the magnetic highway

In December of last year (although the fact that this took place July 28, 2012) space agency NASA announced that the “Voyager 1” entered the area of space where the highly charged magnetic particles begin to seep through the “bubble” nizkozaryazhennyh particles produced by our sun. Thus, the “Voyager” discovers a new region of space – the heliosphere, the presence of which scientists previously did not even know existed.
“This region is notable for the fact that the Sun’s magnetic field is connected to the outdoor space. It’s like a highway, where the particles are moving in the one or the other direction, “- says Ed Stone, one of the scientists of the project.
After “Vodzher-1” achieved this space and transmitted data, which were analyzed by different teams of scientists, including researchers immediately broke out the flames of debate as to whether the probe has reached interstellar space.
1. Outside space
This graph showing data transmitted by the probe indicates that “Voyager 1” reached the interstellar space. The blue line indicates the density of the particles, which fell sharply shortly after the probe left the area of influence of the sun and entered the so-called region of the termination shock (termination shock), where the force of the solar wind (particles ejected by the Sun) repeatedly declined
“Voyager 1” is in the interstellar space and, fortunately for us, it’s enough of a nuclear reactor for a few more years of work and supply of equipment for the possibility of transmission to Earth of new scientific data. His tools are off in 2025, then with the probe will only receive information about his condition. Many thousands of years later and, more specifically, to 40,272, after AD lifeless guide mankind in the vast expanses of space will fly at a distance of 1.7 light years past the star AC +79 3888, located in the constellation Ursa Minor, and then travel to The tour takes about a few million years to the center of our Milky Way .
