On July 1, 2005 at 01:12 SCET-UTC, Cassini started the engine burn required to insert the spacecraft into orbit around Saturn (SOI). Almost 30 minutes later, Cassini was occulted by Saturn's rings as seen from the Earth. The geometric ring occultation covered all main ring features, starting at the outer edge of Ring A at 01:42 and ending at the inner edge of Ring C at 02:40. From 01:12 to 03:07, Cassini X-band radio signal (3.6 cm-wavelength) was turned on, primarily to monitor the burn. The sinusoidal transmitted signal was referenced to the on board ultrastable oscillator, allowing measurement of the signal amplitude and phase at the 70-m ground receiving station of the Deep Space Network at Canberra, Australia. As a useful by-product, a complete ring occultation observation, including free-space baseline, was achieved. Because of the special orientation of the spacecraft during the burn, the Cassini low-gain antenna was used to transmit the signal. Nominal radio occultations are conducted using the high-gain antenna, hence have intrinsic free-space signal-to-noise ratio (SNR) higher by a factor of ~10,000 than the SOI occultation. Nonetheless, clearly detectable signal was observed during occultation by features in Rings A, Cassini Division, and Ring C, but not Ring B. The measurements, after reconstruction to remove diffraction effects, may be used to obtain an optical-depth and phase-shift profiles of resolved ring features. Achievable radial resolution primarily depends on the ring-opening-angle B, available free-space SNR, and occultation geometry. We compare radial resolution achievable for the Cassini SOI occultation (B = 24.7 deg, SNR = 10 dB-Hz) with those of the Voyager ring occultation (B = 5.9 deg, SNR = 50 dB-Hz), and contrast the results with those expected from nominal radio occultations during the Cassini tour. Example optical depth profiles from the Cassini SOI occultation are presented.

  • Maybe the receiver was picking up oscillations or refractions or sidebands or maybe harmonics?

  • @y2knoproblem or maybe it was speech or maybe it really is ET takin a shit who knows, either way its signal being picked up from Saturn.

  • watch?v=33uvhjp7U5Y

  • If aliens were to send a friendly message to us, NASA would hide it. JUst to stop everyone panicking, I think, if we did get a friendly message, we should respond to it. Maybe there's other humans out there? Maybe we're just part of a broken civilisation that fled across the universe and found Earth? Sorry if I sound crazy. :P

  • u dont sound crazy, in fact ur comment proves ur intelligence!

  • @KVLTdotcom The way you type certainly doesn't prove yours.

  • @manka6

    ty for ur words of wisdom, ty for imparting a small portion of ur vast knowledge, truly inspiring! ^^

  • This sound is no mystery.

    Cassini's Radio Science Subsystem (RSS) sent data through the rings. (occultation) Radio signals bounce in-between and through the icy-rocks, creating standing-waves, phase-shifting & ring modulation.

    After altering signal frequency by five octaves, we hear artifacts of standing-waves and ring-modulation.

    It's similar to those "robot-voice" simulators, but only because we associate the effect of ring-modulation to robots in movies. It's cool, but not mysterious.

  • @OldSchoolSkill Then if what you are consistently recording is a recording, then thats all them rings are good for is to leave a recorded message for something or some one else to read when recording near there. But, if its different all the time, then there is live out there, other then ares, which there is, and they are the other Souls of Satan's Fallen Angles that did not over to earth after we went to there planet and some came back with us, thats all.

  • @vind3x Research this HAARP MACHINE THE GOVERNMENT HAS BEEN USING ON HUMANITY AND CHEMTRAILS, AND FEMA CAMPS FOR ALL HUMANS, BETTER HOPE YOU DON'T HAVE ANY THING HUMAN LIKE YOUR SKIN ON YOU.. TREASON BY ARE OWN GOVERNMENT ILLUMINATI OCCULT SYSTEM. EVIL ALWAYS WILL TURN ON YOU IF YOU ARE HUMAN. I THINK WE GOT TO WAKE UP A LITTLE BIT. THATS NOT GOOD THEM CHEMTRAILS.

  • This whole Planet is Energy Period. Energy is to move forward in time of Existence in Eternity ones Soul. If you know what I mean. On a bigger picture of whats going on around use all. Think Bible True bigger picture, kinda of picture. If you know what I mean.

  • The magnetic band that protects this planet from the suns sparking every 11 year is do to happen December 2012 we are not protected from this.

  • I think its the over use of that HAARP MACHINE and they now how to piggy back sound on EMF WAVES with the HAARP, so I think that these sounds could be coming off as energy like a cd when you put something on it, same exact recording like looping would be recorded energy from God knows when, or some one's home, or there universe kind of deal.

  • Assigning tone to light sounds and calling it aliens. Derp.

  • The complex radio spectrum with rising and falling tones, is very similar to Earth's auroral radio emissions. These structures indicate that there are numerous small radio sources moving along magnetic field lines threading the auroral region.

    Time on this recording has been compressed, so that 73 seconds corresponds to 27 minutes. Since the frequencies of these emissions are well above the audio frequency range, we have shifted them downward by a factor of 44.

    No aliens...

  • In spite we don't certainly know what could be causing these strange sounds or intriguing radio signals, the wonders of our Universe are endless... :)

  • Sounds like speech or throat singing!

  • @KVLTdotcom Yeah on a gas giant :\
