Voyager 1 stops communicating with Earth
Voyager 1 stops communicating with Earth
NASA’s 46-year-old Voyager 1 spacecraft has experienced a computer glitch that prevents it from returning science data to Earth from the solar system’s outer reaches.
There is a discussion on Hacker News, but feel free to comment here as well.
Love to see if they can get it going again. The return on investment of these things is crazy and it’s wild to think they’ll be a marker of our civilization long after we’re gone. If it is the end, it’s had a hell of a run.
at some point we'll be lucky to receive any signal at all as the systems degrade. maybe its the beginning of the end
The problem is the power supply, a radioisotope thermoelectric generator (RTGs). They can produce power for years, but the issue is that the power output declines. Originally it was designed to provide 470 watts, but now it's down to 250 watt...
This is the best summary I could come up with:
Engineers are currently trying to solve the issue as the aging spacecraft explores uncharted cosmic territory along the outer reaches of the solar system.
Their exceptionally long lifespans mean that both spacecraft have provided additional insights about our solar system and beyond after achieving their preliminary goals of flying by Jupiter, Saturn, Uranus and Neptune decades ago.
The mission team first noticed the issue November 14, when the flight data system’s telecommunications unit began sending back a repeating pattern of ones and zeroes, like it was trapped in a loop.
While the spacecraft can still receive and carry out commands transmitted from the mission team, a problem with that telecommunications unit means no science or engineering data from Voyager 1 is being returned to Earth.
As both Voyager probes experience new trials, mission team members have only the original manuals written decades ago to consult, and those couldn’t account for the challenges the spacecraft are facing as they age.
In August, the mission team used a long-shot “shout” technique to restore communications with Voyager 2 after a command inadvertently oriented the spacecraft’s antenna in the wrong direction.
