Fixing Voyager: How NASA Restored Communications with Voyager 1 from Across the Solar System - YouTube - solar system studies/interstellar studies

with Gregory Smith,communications and education directorate,NASA/JPL;Calla Colfield,media relations specialist,NASA/JPL;Kareem Badaruddin,Voyager mission manager;and Dr.Linda Spilker,Voyager project scientist*Both Voyager spacecraft are now in interstellar space,doing groundbreaking research on the interstellar medium.*The software engineering was needed to correct a hardware failure due to a part failure or cosmic radiation.There are five instruments on each Voyager that are still working:1.the magnetometer,measuring the intensity and direction of the magnetic field;2.the plasma wave detector,that actually measures the radio signals in space;3.the low energy charged particle instrument,measuring low energy cosmic rays,protons,electrons and molecules-it actually can step and measure in eight different directions;4.the plasma spectrometer,which measures the composition,temperature and density of the plasma in the interstellar medium;and 5.the cosmic ray spectrometer that measures the higher energy cosmic rays,the cosmic rays and particles coming from supernova explosions.

The Voyager spacecraft explored the ice giants Saturn and Jupiter,discovering the first ever volcanic activity outside of Earth on Jupiter's moon Io.Later,the Galileo spacecraft studied Jupiter's moon Europa,revealing that it's surface is covered by ridges and cracks,the strongest evidence of an ocean beneath its icy crust.The Juno spacecraft,launched in 2011 and arriving at Jupiter in 2016,made recent flybys of Jupiter's moons Ganymede,Europa and Io from 2021 to 2024.Juno's mission has been extended to 2025.Where there are heat and water,there may be extraterrestrial life.
