Voyager 2 is 35 years in space

Voyager 2 is 35 years in space

2 Happy Birthday! 35 years ago, launched the first Probe Voyager, which continues to operate today, becoming the oldest operational spacecraft in history.

was followed by its twin Voyager 1, launched on September 5, 1977. Voyager 2 is still the only probe that has visited Uranus and Neptune, and is currently trying to get out of the solar system. He looks forward to when that time comes, that we can learn more about the space beyond the influence of our sun.

Despite his age, Voyager will continue informing us of what lies beyond. The probe uses three thermoelectric generators based on radioisotopes – each includes 24 spheres of plutonium oxide that could generate 157 watts of power at launch. Adding all, 35 years ago generated 470 watts of power. It is expected that the system will remain functional until at least 2020, maybe even 2025.

Voyager 2 is about 15,000 million kilometers from the sun, heading south, while Voyager 1 is to 18,000 million kilometers north. Both spacecraft have been exploring in recent years topcoats of the heliosphere, the range of influence of our sun.

“We keep hearing from the Voyager 1 and 2 almost every day. Both ships are well placed to have flown through the dangerous radiation from Jupiter and have to endure the cold of being so far from our sun, “said Suzanne Dodd, the Jet Propulsion Laboratory of NASA.

The Voyager 2 uses a 3.7-meter dish antenna to send data to the Deep Space Network, a series of huge antennas on Earth to capture the spatial cues.

The ship managed several discoveries since its launch, including the rare air currents in the polar region of Saturn, tilted magnetic poles of Uranus and Neptune’s moon Triton geysers of the latter planet and others.
