Show Notes for July 2nd (Show 105) Ryan Mullahy
Shows are recorded live on the Dark Matter Radio Network every Wednesday at PM Eastern Standard Time, GMT/01:00 UTC and podcasts of the live shows posted the following Thursday. You can join the Chat Room on right sidebar of our home page and interact live each week.
Most of you probably have heard our regular guest, Stan Friedman had a heart attack. I have been communicating with Kathleen Marden, and this is her direct quote: Stan had a mild heart attach on Friday night. He is now feeling chipper and is resting in the hospital while he awaits further testing. His doctors have advised him to rest and recuperate, so he’s had to cancel his upcoming engagements in Roswell, NM, and Cherry Hill, NJ. We are all pulling for you Stan, we need you, so speedy recovery to you.
On even a sadder note, our past guest Terry Hansen, a young man passed away last Thursday, June 26th. He had a massive coronary in his sleep. Researcher Robert Hastings who was a good friend of Terry’s wrote me, “ Terry was a pioneer, and a first class act. He was mostly noted for the book, The Missing Times. I really enjoyed him on the show, and was hoping to have him back, here is a quick clip of our show in January, 2013.
Life on Enceladus
by Andy Fleming
The possible haunts of ET (or at least extra-terrestrial microbes) are moving further out into our solar system, from Mars to Jupiter and its moon Europa, to Saturn’s Titan, and most recently to its icy moon Enceladus. This enigmatic little world is the sixth largest of Saturn’s sixty two moons and was discovered in 1789 by William Herschel.
NASA’s Cassini spacecraft has made several flybys of the 500 km diameter moon over the last ten years and has discovered plumes of water vapour erupting into space. These emanate from fractures and striations around the South Pole that planetary scientists have called tiger stripes. Over the eons, the ejected material from this so-called cryo-volcanism has created Saturn’s beautiful E ring.
Cassini has actually ‘tasted’ one of the plumes and after a fly-through, scientific analysis showed that the geysers on Enceladus contain organic molecules. Although these are not alive in themselves they are based on carbon chemistry.
Last April NASA announced the startling discovery that there is an ocean up to ten kilometres in depth and the size of Lake Superior at the moon’s South Pole. This is the location of the majority of the geysers and is a result of the friction and heat generated by Saturn’s immense gravitational tidal forces.
This of course raises the tantalising possibility of extra-terrestrial life on Enceladus. Astrobiologists state that the main requirements of life are water, energy, and chemical nutrients. All of these are present on the moon. Many are now citing Enceladus as a better candidate for the discovery of life than Europa due to its thin crust and out-gassing of water vapour.
