The Voyager 2 probe, which recently brought a lot of valuable data across interstellar space to mankind, suddenly shut down all of its scientific instruments due to a lack of power, according to the MIT Technology Review website. The probe is still on track, but its dynamics are not promising.
Voyager 2 is the second probe to cross the boundary of the heliospheric layer, launched earlier in 1977, the sister probe Voyager 1, which had been in operation for five years but has now been in space for 42 years. As recently as the end of 2019, humans had the first data for Voyager 2’s passage through interstellar space , and five studies were published simultaneously in the British journal Nature Astronomy, confirming that Voyager 2 had entered interstellar space on November 5, 2018, making another important technical achievement in the history of science.
Currently, Voyager 2, 11.5 billion miles from Earth, had planned to perform a routine 360-degree rotation to calibrate the magnetometer, but this was delayed for unknown reasons, resulting in two internal systems running at high power, and the spacecraft’s software shut down five scientific instruments still in operation to make up for the power shortage. The boundary of the heliosphere was found thinner and smoother than previously thought, and there was a layer between the top of the solar sphere and interstellar space, where solar and interstellar winds interacted, which Voyager 1 had never found before.
After realizing that the spacecraft was in “fail-safe mode,” NASA engineers quickly shut down one of the power-hungry systems and restarted the science instrument. But Voyager 2 didn’t get back up and running soon, and no data was sent back. However, NASA’s instructions from Earth to the Voyager 2 spacecraft take 17 hours, and vice versa. This delay in communication also means that it takes a lot of time to solve the problem.
So far, engineers have re-opened the Voyager 2 scientific instruments, the spacecraft is still in operation, but it does not seem to be fully restored, engineers also think that its power condition is very unstable, if one day “Traveler 2” can no longer point the antenna to Earth, then the mission will officially end.
Editor-in-chief circle point
Voyager 2 is a human contributor to understanding interstellar space! Until the end of the 19th century, many people thought that this vast world was nothing, it was two small ships that gave us a rich understanding of the area. But while Voyager 1 was the first to cross, the results were not satisfactory in terms of scientific data , when the plasma equipment on the probe was damaged and scientists failed to get the full data , and Voyager 2’s scientific equipment was very competitive . Now, our understanding of interstellar space is still nothing more than fur, farther away from the sun, and there is much debate about the space that has not yet been explored, and one would like to see the ship continue to work wonders, even though it has been in service for too many years.
