Question

how is energy consumption of interstellar spacecraft such as voyager 1,2,gallelio Pioneer 10 is been fulfilled ??how is the energy given to them such that they still works for many many years is space with accuracy?? example voyager still works but energy was given to it in 1977 why isn't energy exhausted till now??

Answer 1

Answer:

When Voyager 1 and 2 crossed the heliopause, their still-functioning particle instruments revealed the historic events. The heliosphere works as a shield, keeping out many of the higher-energy particles created by the cosmic rays produced by other stars. By tracking both the low-energy particles found inside the solar system and the high-energy particles from outside of it, the instruments could reveal a sudden surge of cosmic rays alerting scientists that the spacecraft had left the solar system.
