The Never-Ending Voyager Missions (Encore)
Summary
This episode explores the ongoing interstellar mission of the Voyager probes, launched in 1977, which continue to transmit data despite being over 45 years old. It details how radioisotope thermoelectric generators power the spacecraft and how NASA’s Deep Space Network detects their faint signals across billions of miles. The discussion covers the challenges of maintaining 1970s-era computers and the scientific discoveries made in interstellar space, such as the density of the medium and cosmic ray intensity. Finally, it outlines the probes’ eventual end of communication and their future tr…
