New Delhi:
NASA’s 47 yr previous spacecraft has executed wonders. Spacecraft Voyager 1 has as soon as once more contacted Earth from 15 billion miles away from Earth. A spacecraft named Voyager 1 contacted the Earth with the assistance of a radio transmitter. The particular factor is that this transmitter was not used since 1981. In such a scenario, that is excellent news for scientists. After contact with Earth, many sorts of speculations are being made.
NASA’s 47-year-old Voyager 1 spacecraft not too long ago established contact with Earth after a short pause with the assistance of a radio transmitter that has not been used since 1981. NASA engineers on the Jet Propulsion Laboratory (JPL) in California reestablished contact with it. Spacecraft on October 24.
The spacecraft, which is greater than 15 billion miles away in interstellar house, skilled a short interruption in communications on October 16 because of the shutdown of one in all its transmitters. The shutdown was doubtless brought on by the spacecraft’s fault safety system, which shuts down sure techniques when energy utilization turns into too excessive.
In keeping with CNN report, NASA engineers from the Jet Propulsion Laboratory (JPL) in California re-established contact with the spacecraft on October 24. Earlier on October 16, contact with the spacecraft was misplaced after one in all its transmitters shut down. The shutdown was doubtless brought on by the spacecraft’s fault safety system, which shuts down some techniques when energy is just too excessive.
In keeping with NASA, it takes about 23 hours for a message to journey in a single path – from Earth to Voyager 1 and vice versa. When NASA engineers despatched a command to the spacecraft on October 16, they didn’t know its response till October 18. A day later, communications with Voyager 1 stopped fully.
CNN quoted NASA as saying that it takes about 23 hours for a message to journey as soon as from Voyager 1 to Earth or from Earth to the spacecraft. When NASA engineers despatched a message to the spacecraft on October 16, there was no response till October 18. A day later, communication with Voyager 1 was fully misplaced.
Voyager 1 was launched by NASA in 1977.
After investigation, the NASA staff found {that a} malfunction of Voyager 1’s security system had induced the spacecraft to change to a different, lower-powered transmitter. In keeping with CNN, Voyager 1 has two radio transmitters, but it surely has been utilizing just one transmitter, referred to as ‘X-band’, for a number of years. The second transmitter, ‘S-band’, makes use of a distinct frequency, which has not been used since 1981.
Potential threats are being detected
For now, NASA has opted to keep away from switching again on the X-band transmitter till they will work out what activated the fault safety system. This course of could take a number of weeks. Bruce Wagner, Voyager’s mission assurance supervisor, advised CNN that engineers are exercising warning as they wish to decide whether or not X-band activation poses any potential dangers.
