NASA is Making Sacrifices To Keep the Voyager Mission Alive

NASA has begun shutting down science instruments aboard the twin Voyager spacecraft to extend their 47-year journey through interstellar space, officials said. Voyager 1's cosmic ray subsystem was deactivated on February 25, while Voyager 2's low-energy charged particle instrument will be shut down on March 24. Both spacecraft will then operate with just three of their original ten science instruments.

The radioisotope power systems aboard the Voyagers lose approximately 4 watts annually, threatening to end their mission within months without intervention. 'Electrical power is running low,' said Voyager project manager Suzanne Dodd. 'The Voyagers have been deep space rock stars since launch, and we want to keep it that way as long as possible.' NASA engineers believe these measures could enable the probes to continue operating into the 2030s, far beyond their initial five-year design life.
