In the news today, are reports of "outer-space-type music" that the Apollo 10 crew heard.
From the mission transcript (page 197 of the PDF):
CDR Commander Thomas P. Stafford CMP Command module p_lot John W. Young LMP Lunar module pilot Eugene A. Cernan SC Unidentifiable crewmembcr CC Capsule communicator (CAP COMM) 04 06 13 02 LMP That music even sounds outer-spaeey, doesn't it? You hear that? That whistling sound? 04 06 13 06 CDR Yes. 04 06 13 07 _4P Who0ooooo. Say your - - 04 06 13 12 CMP Did you hear that whistling sound, too? 04 06 13 14 _P Yes. Sounds like - you know, outer-space-type music. 04 06 13 18 _4P I wonder what it is.
NASA's explanation of this sound is that the radios on the command module and lunar module were interfering with one another. Cassini also had a similar experience, and that was explained as charged particles moving through the magnetic environment around Saturn creating distortions in ways that cause those odd sounds.
Have either of these "problems" been corrected with newer space craft or is such interference rare enough that it's not actually a problem?
