A view of the planet we live on

Voyager 2 Went Into Fault Protection Mode, But Engineers Brought it Back Online

NASA’s Voyager 2 spacecraft went into fault protection mode on Tuesday January 28th. The fault protection routines automatically protect the spacecraft in harmful conditions. Both Voyagers have these routines programmed into their systems.
After it happened, NASA engineers were still in communication with the spacecraft and receiving telemetry.
The fault protection stems from a maneuver attempted on January 25th. On that day, Voyager 2 was supposed to execute a scheduled rotation maneuver. The spacecraft rotates itself 360 degrees to calibrate one of its instruments, MAG, the triaxial fluxgate magnetometer. That instrument is investigating the solar wind boundary with the interstellar magnetic field and beyond. 

NASA says there was a delay in the maneuver, which caused two systems that draw a lot of power to be on at the same time. There’s a tight power budget on Voyager 2, because its radioisotope thermoelectric generators are running down. To protect itself, the spacecraft went into its fault-protection mode. In that mode, it shut down scientific instruments to make up for the power deficit. By January 28th, engineers had successfully shut down one of the two high-power-drawing systems, and turned its science instruments back on.
After that, they still weren’t receiving data from the spacecraft.
Voyager 2 is still running, but its power situation is precarious. Mission engineers are constantly evaluating the status of the power system, and they know that it’s losing about 4% of its power each year. A lot of power is needed to keep systems on the spacecraft from freezing, including fuel lines. If those lines froze, and broke, then Voyager 2 would no longer be able to point its antenna towards Earth, and the mission would effectively be over.

This is one interesting image

From the archives: String theory, the multiverse and other ideas of modern physics are potentially untestable. At a historic meeting in Munich, scientists and philosophers asked: should we trust them anyway? https://quantamagazine.org/physicists-and-philosophers-debate-the-boundaries-of-science-20151216/

I was reading what one of the thinkers of the Age of Enlightenment was saying about art and he said art is frozen poetry. 
I like art that tells you a story just like a good poem does.
