NASA's Voyager 2 has become the second thing that has always been done in history to reach the edge of the solar system, after the spacecraft moves out the deflection bubbles of the items and the funding subscriptions created by the Sun, named.
His twin, Voyager 1, started over his & # 39; This end in 2012, but Voyager 2 – has been launched 41 years ago – giving a workstorm that will deliver it; This first type of view of the nature of this gateway to an inter-state place.
Voyager 2 is now just over 18 billion km from Earth, NASA said recitedSouth Westerly
Although the probes of the activity left, Voyager 1 and Voyager 2 have left the solar system, and do not. Leave at any time as soon as the US spacecraft said.
Land of bands
Comparing data from different instruments that were aboard the space route, scientists put the decision that the confirmation of the exterior edge of the world turned on November 5.
This boundary, known as heliopause, is where a hot sun wind, and meet the cold middle, close inter-state. Mission staff can communicate with Voyager 2 as it goes into the new phase of his trip, but information – a & # 39; move at the speed of the light – giving about 16.5 hours to travel from the spacecraft to Earth.
In comparison, light from Sun travel to; Take about eight minutes to reach Earth.
The most severe evidence of Voyager 2 left from the heliosphere since its attack on Plasma Science Experiment (PLS), a machine that stopped working on Voyager 1 in 1980, long before that probe turned on a heliopause.
"I'm working on Voyager that I feel like a researcher, because everything we see is new," said John Richardson, the principal Inspector for a PLS device.
"Even though Voyager 1 was over the heliopause in 2012, it did so at a different location and a different time, and without PLS information. So we still have a # 39 ; see unprecedented things, "said Richardson, a leading research scientist at the Massachusetts Institute of Technology (MIT) in the USA.
Probe inter-state room
As well as plasma data, members of Voyager science team have witnessed evidence from three other abrasive abrasions – the radical cosmetic subsystem, the low grinding instrument with energy power and the magnetometer – according to its determination that Voyager 2 over the heliopause.
"There is still a lot to learn about the division of inter-state vision just outside heliopause," said Ed Stone, a Voyager project scientist based at Caltech in the US.
Together, the two Voyagers provide a detailed insight into how our heliosphere interacts with its & # 39; continuous interstate wind that flows from outside.
The information that is being monitored by the NASA Interstellar Boundary Explorer (IBEX), which aims to Endless awareness of that end.
NASA is also preparing an additional mission – the Future Interpretation Mapping and Acceleration Priority (IMAP), due to its launch in 2024 – to take advantage of Voyagers' views.
Voyager 2 was launched in 1977, 16 days before Voyager 1, and the two have traveled well beyond their goals. The spacecraft was built for five years and close surveys of Jupiter and Saturn.
But, as the intention was followed, an additional confirmation of the two largest major plans, Uranus and Neptune, was made possible.
As the spacecraft passed over the solar system, a remote control re-registration was used to make the Voyagers greater capacity than they had when they left Earth.
Their five-year-old animals have been extending to 41 years, and making the easiest NASA Voyager 2 mission running.
