A group of NASA Jet Propulsion Laboratory engineers have noticed that Voyager has reduced its propulsion in recent days. This could have caused Voyager to go in an undesirable direction. On the other hand, there was a way to fix it, but at the same time there were some problems. Spare engineers designed by engineers last worked in 1980.
The team had to go back to the original Voyager documentation to revive still journalists. The team that checked the codes finally sent a signal on November 28th to operate the pushers. It took 19 hours and 35 minutes to get to Voyager, 13 billion miles from the radio waves, and the result was positive. The backup engines are here.
