Uncharted Territory
The Voyager mission is incredibly important, as it helps in NASA’s studies covering heliophysics. These studies first began with the Sun and have since extended to everything the solar wind touches. However, Voyager 2 is sending back information almost surpassing the Sun’s influence, which is uncharted territory.
Remaining Functional
Although Voyager 1’s PLS isn’t functioning, both spacecrafts are believed to remain operational until 2025. After this, these probes might lose electricity, putting an end to operations. Nonetheless, both would have been in space for more than 50 years.
