This artistic concept map shows NASA's two "travelers"
Spacecraft exploring a turbulent region in space, with immediate sheath, which is around the bubble of charged particles around the sun outermost.
"Travelers" on the 1st probe launched in 1977,
Is currently about 18 billion kilometers from the sun, is in the universe to fly the farthest human detectors. Since 2012, scientists have been eagerly awaiting its historic moment flying out of the solar system. NASA news release said, Voyager 1 has been flying out of the solar system confirmed officially into interstellar space!
Project scientists believe that Voyager 1 spacecraft is equipped with an instrument display has been out of the solar system's heliosphere surrounding area, is now sailing in interstellar space. Voyager 1 (Voyager 1) is an unmanned space probe the outer solar system, weighing 815 kg, on September 5, 1977 launch, the original plan was visited and inspected the outer solar system planets, such as Jupiter and Saturn . They provide the first clear high-resolution satellite photos. It is the farthest from the Earth and flying the fastest man-made vehicle, the true sense of flying out of the solar system for the first time into the galaxy space.
Today, the Voyager spacecraft from Earth has about 19 billion kilometers, the signal propagation speed of light also need to take 17 hours to reach.
Travelers year project chief scientist Edward Stone (Ed Stone) professor, said: "This is an important milestone when 40 years ago we started this project, today is exactly what we have been hoped for - that that we can have an interstellar spaceship. "he said:" For a scientific perspective, this is an important milestone in, but it is also historic, just as we have completed the first voyage around the world, or humans first set foot on the lunar surface, as this is our first time to directly explore interstellar space. "
Before analysts have long recognized the Voyager 1 spacecraft, the spacecraft carrying the instrument display their environment is changing. This allows researchers eventually convinced the spacecraft has left the solar system data from the plasma wave science equipment (PWS), this device is designed to measure travelers spacecraft charged particles in ambient concentrations.
4 to 5 months of this year, and last year's 10 to November this instrument readings show its surrounding space proton concentration increased 100-fold. Scientists have long before this has projected that if the Voyager spacecraft to reach the outer edge of the solar magnetic field range of the peak of such particles occurs.
When scientists these instruments as well as data from other devices to inspect integrated with reading, they finally officially confirmed Voyager spacecraft to leave the solar system roughly occurred in August 25, 2012. In the August 25, 2012, Voyager 1 was from the Earth about 121 astronomical units. An astronomical unit is the distance between the Earth and the Sun.
American University of Iowa professor Don Garnett (Don Gurnett) PWS device is chief scientist, said: "This is indeed an unusual event, impressive - it is human's first flying objects in the solar system. " British Astronomer Royal, Sir Martin Rees (Sir Martin Ree) said:" The really feel incredible, the human use of 1970s technology manufacturing fragile objects could have arrived so far space. " Although Voyager 1 is now out of the solar system, traveling in between the stars, but it is still subject to the gravitational field of the sun, like a lot of comets as affected by the gravitational field of the sun, even They are very far away from the sun.
But in the strict definition, the spacecraft has indeed left our solar system most people define it now in a completely new area. 1977 9 5 March, Voyager 1 left Earth, only than its sister spacecraft Voyager 2 nights a few days. As of 1989, these two sister spacecraft has successively completed Jupiter, Saturn, Uranus and Neptune investigation.
Then they continued their flight towards the outside of the solar system, according to estimates, they carry plutonium batteries (nuclear power battery) will last about 10 years, to 2025 will eventually depleted, at which time they are about 20W power supply will eventually stop . limitless universe, despite being up to 45 kilometers per second, ultra-high speed flight within the next four years, Voyager 1 will not reach any other star, Professor Edward Stone said: "The next few one billion years, Voyager 1 will work together with the other hundreds of billions of stars rotating around the center of the galaxy. " However, this did not Travelers spacecraft mission to complete.
The battery-powered as long as they can, their instruments still work, they will continue to inspect the space environment along the way. Currently Voyager 1 spacecraft in which the environment is a huge star explodes after millions of years ago shaped diluted substances.
The scientific community has been indirect evidence and theoretical models to describe the Voyager 1 spacecraft is currently the environment, but now, Voyager 1 spacecraft will have the opportunity for the first time on these theories and evidence for direct verification measurements.
Famous British planetary scientist Fred Taylor (Fred Taylor) commented Professor said: "When I was a young postdoctoral fellow, I have the Jet Propulsion Laboratory in California and the year of the study group together work to develop programs of external examination of the solar system planets, the project is later travelers spacecraft project.
"He said:" At that time we felt truly on Jupiter, Saturn inspect simply incredible, not to say that Uranus and Neptune up! Talking to fly out of the solar system spacecraft, we were not fully considered, because it is too far away, we did not even discuss this, even though we all know that one day it will actually happen, whereas in the time every 43 years later, that day has finally arrived, our Voyager probes are still to new frontiers. "
