What happened with Voyager over the past 42 years in space?

There is a perception that the probes Voyager — the best that were made by the representatives of our species. The voyagers left Earth from Cape Canaveral in 1977. Since then, the spacecraft gave scientists a huge amount of data about the Solar system. Thanks to Voyager we know so much. In December 2018, the probe Voyager 2 . But despite the fact that both spacecraft are still sending us data, equipment Voyagers of aging and communication with them may be interrupted at any moment.

Mission Voyager

During the arms race between the USSR and the USA, each party strove to overtake another. In the 1970s, the era of robotic spacecraft. The first automatic interplanetary station "Luna-16" was launched by the USSR in September 1970. The spacecraft successfully reached the moon and returned to Earth, bringing scientists the lunar soil.

NASA's Response was not long in coming. In 1972 into space flew the first machine that did not need to manage. "Pioneer" made up and photographed a gas giant. Five years later went into space robotic spacecraft Voyager with a gold plate attached to the housing.

On each of the plates, according to the idea of a prominent astrophysicist and science popularizer Carl Sagan, the Phonographic way of recorded information about our civilization. This is done in case on the way Voyager will meet intelligent life forms.

But what do you think, is the launch of Voyager of mankind? Share your opinion in our .

What's going on with Voyager today?

Initially, the goal of the Voyagers was to study Jupiter and Saturn. As a result, the spacecraft sent back data about four planets and their satellites. For 42 years the Voyagers are moving away from the Earth. But even beyond the heliosphere probes continue to transmit new data scientists.

But the equipment is aging. As a result, each day could be the last Voyagers. This occurs because machines wear out, and the generators produce approximately 40% less electricity than at the start.

«chaos» in person

In July this year, NASA has developed a to maintain probes. To support the Voyager on the go, scientists have to make difficult decisions. Using radio waves, they transmit the apparatus of the different teams. So, Voyager 2 received instructions to switch to which the probe is not used since 1989. Engines help the Voyager is in a steady state, and those who used the probe gradually failed.

The Idle engines of the Voyager can lead to the fact that the device will not be able to keep the antenna towards the Earth. And this is the only point of contact between the probe and us. Voyager 1 is also moved to the spare engines last year.

However, the engines aren't the only problem. For devices installed heaters, through which the probe does not freeze in outer space. But recently, engineers have turned off the heaters Voyager-2. The decision was made after much deliberation — off of the heaters will allow the probe to economize energy. The trip was made after the information that Voyager left the Solar system confirmed.

"Voyager"

A Possible reason for the current difficulties is the fact that in 1977 no one thought about interstellar travel. NASA engineers were focused on the study of the planets of the Solar system. Both devices simultaneously reached Jupiter after Voyager 1 went on to Saturn and . Most scholars interested in the Titan. It was planned that if for some reason, Voyager-1 will not collect sufficient amount of data, followed by direct Voyager 2. When both probe successfully coped with the task, they went to Uranus and Neptune.

Soon after, the engineers thought about saving energy. The first step was to disconnect cameras as capture the scattered stars was not necessary.

After 37 years of inactivity

The flight of the Voyager is influenced by many factors. In 2012, after the release of the Voyager 1 spacecraft beyond the heliosphere — a kind of bubble enveloping our Solar system, the space environment has changed dramatically. This resulted in the shutdown of a number of instruments for their uselessness. After all, the Voyagers hunted today on cosmic rays, magnetic fields and other detectable phenomena in outer space.

And yet, sooner or later the time comes to release the Voyagers in free swimming. In the end, at some point transmitters, through which we support with the Voyager connection will fail. Or standby engines with which devices work today, too, will fail. The options can be many, but we together with engineers from NASA, we wish Voyager a good way.
