Voyager 2: After a deep radio silence, a signal comes back
Voyager 2 probe has been drifting through space for over 43 years. The daring probe has been drifting through Space for over 43 years.
It was quiet around the Voyager 2 space probe for a long time. We could not obtain a signal because the antenna on Earth had to be serviced.
The Voyager 2 space probe has been on its mission in Space for over 43 years. The further it moves away from us, the more difficult it becomes to maintain contact with the probe. There is only one antenna left in the world that can be used to communicate with it. It is located in Australia and is part of the Canberra Deep Space Network.
However, this antenna had to be switched off last year because some maintenance and updates had to be carried out. During this time, it was on its own. If there had been an emergency, there was nothing we could have done for them from Earth.
The antenna in Canberra is now online and ready for use again. For the initial time in a long time, Voyager 2 and Earth’s radio link is also used. The message has to travel a long way. It takes 17 hours and 35 minutes to get from Earth to the probe. On the evening of February 14th to 15th, 2021, the Voyager 2 reported back and reported that everything was ok.
The radio connection should be kept stable. In the next step, an instruction is sent that the probe should switch off one of its sensors. This saves electricity, which means that the radio connection should be maintained for as long as possible.
Voyager 2 has been in interstellar Space for a long time. Its little sister probe, the Voyager 1, reached an extremely impressive milestone last year.
