Voyager 1 radio that was shut down in space for 43 years is back on Nasa receives signals

NASA Voyager spacecraft: American space agency NASA has again made contact in space with a 47 year old satellite. This contact has occurred with the Voyager-1 spacecraft, which is the longest mission in America’s space history. In the year 1977, NASA launched Voyager 1 and Voyager 2 spacecraft within an interval of a few weeks. Accordingly, he has been working for about 47 years. of voa Report According to NASA, in recent years NASA was having difficulties in communicating with the Voyager spacecraft. In April this year, NASA had said that it has not been able to communicate with the ‘Voyager 1’ spacecraft for 5 months.

Scientists were not able to understand spacecraft

According to the report, NASA officials said that there was a defect in a chip in the onboard computer of ‘Voyager 1’. Because of this, the scientists were not able to understand the data that the spacecraft was sending. However, scientists changed the method of reading and the problem was fixed to some extent.

After this, communication issue arose again in October. Because of this, scientists were getting the data of ‘Voyager 1’ late. That problem was related to the radio transmitter system of the spacecraft.

After this, when for some reason NASA asked the spacecraft to turn on one of its heaters, the fault protection system of Voyager 1 was activated. Its purpose was to save electricity. In such a situation, the spacecraft started sending signals in other ways instead of the radio signals they usually send.

The situation was such that NASA started receiving signals on S-band instead of the normal X-band. When NASA started receiving them, data started coming from the spacecraft again. NASA says that S-band is much weaker than X-band, so they were trying to start X-band radio communication system for a long time. Interestingly, NASA has not used S-band since 1981. This means that the agency has received signals from Voyager 1 in a different way after 43 years.

The Voyager 1 and Voyager 2 spacecraft were designed to visit Jupiter and Saturn. Both spacecraft completed their work well. Voyager 2 even came close to Uranus and Neptune in 1989.
