NASA’s Cassini spacecraft records eerie sounds during Saturn mission

NASA’s Jet Propulsion Laboratory has released a video which reveals a spooky sound captured by the Cassini spacecraft during its journey around Saturn last year.

The sound is actually the interaction of plasma waves between Saturn and one of its moons, Enceladus. This was published in a research led by physicist Bill Kurth at the University of Iowa.

Researchers converted the original recording into a “whooshing” audio file to enable humans to hear the sound. This was converted in the same way that a radio translates  electromagnetic waves into music.

The Radio Plasma Wave Science (RPWS) instrument captured this recording on September 2, 2017, two weeks before Cassini crashed into the atmosphere of Saturn and died, an official statement said.

“Much like air or water, plasma (the fourth state of matter) generates waves to carry energy,” NASA explained.

“Enceladus is this little generator going around Saturn, and we know it is a continuous source of energy. Now we find that Saturn responds by launching signals in the form of plasma waves, through the circuit of magnetic field lines connecting it to Enceladus hundreds of thousands of miles away,” AH Sulaiman, lead author of the paper, said.
