Your recent re-iteration of a claim to have originated the idea of oceanic life on Europanote 1 prompts me to remind you, and others who may be seeing this text, that this and several other claims you have made are false.
1. Ocean on Europa
In March 2004, in a message to Rob Roy Britt of space.com, you wrote:
"Clearly, I was NOT the first (nor have I ever claimed to be) to propose an original liquid ocean for Europa."On 4 December 1997, on Coast to Coast AM, you said this:
"[W]hen I was covering the Voyager story out at JPL in the Summer of 1980, actually the Spring of 1979 and the Winter of 1980, we flew this extraordinary spacecraft, NASA did, by Jupiter for the first time and encountered the four moons, you know, Io, Ganymede, Europa, Callisto, and Jupiter itself, and it was as part of that observation that I began work on essentially what turned out to be the first scientific paper, which ultimately appeared in Star and Sky Magazine in the beginning of 1980, which was a prognostication, pulling all the data together, that there might be a global ocean under the ice cover that Voyager had revealed and that in that global ocean there actually might be some extant living life forms." (emphasis added)That looks very like a prior claim to me. It is certainly not justified--Lewis (1971)note 2 and Consolmagno (1976) were ahead of you, as were Cassen, Reynolds, and Peale (1979).note 3 I think you know this.
2. Life in Europa's ocean
This is, of course, a separate question, and there is no doubt at all that you have repeatedly claimed to have been the first to publish on this conjecture. However, as Greenberg notes:note 4
"On June 19th and 20th, 1979, the conference "Life in the Universe" took place at NASA's Ames Research Center. Benton Clark gave a lecture Sulfur: Fountainhead of Life in the Universe at that conference in which he discussed the biochemistry of those deep-sea vent communities discovered on Earth, pointing out that they do depend indirectly on sunlight: Photosynthesis near the surface of the oceans produces the oxygen that those communities require. Clark then explained how sulfur could play the role of oxygen, and that deep-sea volcanic emissions could potentially provide all the necessary ingredients for a self-sustained ecosystem. In the final part of his lecture, Clark raised the possibility that life might exist in undersurface oceans on the icy satellites in our Solar System, including Europa, Ganymede, and Callisto in particular." (emphasis added)In the written version of his lecture, Clark wrote:
"Consider H2O-rich bodies. In our Solar System, this includes not only Earth, but quite possibly Mars and Triton, and certainly Ganymede, Callisto, and Europa. Liquid water does not exist at the surface of any of these bodies, except Earth, but we should not discount the existence of "buried" liquid water reservoirs. ... Habitable zones include not only the surface ocean environment, but also the much more probable subsurface oceanic regions. Earth-like environments as abodes for life may be the exception rather than the rule. Occupation of the much more abundant buried zones is possible, and these should ultimately become an object of exploration. Whether such environments can support life long enough and at a sufficient level of activity to permit the evolution of highly encephalized forms (intelligent life) is conjectural." (emphasis added)Prof. Greenberg notes other prior work. You have characterized his comments as political, but in fact they are purely scientific. Claiming credit for other peoples' work is an unattractive trait in anybody, but for somebody who calls himself a scientist,note 5 it is particularly deplorable because of the importance of intellectual priority in that domain.
3. Creation of the Pioneer "message to the Universe"
On your website you refer to yourself as "co-creator of the 'Pioneer plaque'." (scroll all the way to the bottom of the long page). On 13 July 1990 you said "Carl [Sagan] for many years has been taking public credit for the Pioneer plaque which, of course, Eric Burgess and I conceived." In fact you had no part in the design or creation of the plaque, which was done by Sagan, his then wife Linda, and Frank Drake. As for "conceiving" it (as distinct from "creating" it,) that was overwhelmingly to the credit of Eric Burgess. In the epilogue to his 1982 book, By Jupiter: Odysseys to a Giant, Burgess wrote:
"I came up with the idea [that the craft carry a message from Earth]. And I mentioned it [at lunch that afternoon] to Hoagland [then a freelance writer] and Don Bane [Los Angeles Herald Examiner ]. . . . And I said that the right man to get this onboard would be Carl Sagan. So I went around to JPL [NASA's Jet Propulsion Laboratory] -- Hoagland was in tow with me -- and found Sagan. . . . And I said, "Hey, Carl, I've got an idea for you." All Hoagland did was support me and say it's a good idea."
4. The "hammer and feather" stunt on Apollo 15
On 2 July 2013, on Coast to Coast AM, you claimed that this was your original idea. The truth is that it was, in fact, dreamed up by Dave Scott, Jim Irwin, and Joe Allen.note 6
5. The catchphrase "On the internet nobody knows you're a dog."
On 11 November 2015, on your digital radio show, you claimed to have "coined" this bon mot. You repeated the claim much more recently, on Howard Hughes' radio show, 11 November last year. The original was a caption to a cartoon in New Yorker published on 5 July 1993. Credit for the phrase belongs to cartoonist Peter Steiner, not you.
Would you kindly make an early opportunity to withdraw your claims and apologize to those whose work you have falsely taken credit for?

[1] The Other Side of Midnight (notice)
Partial text: Thirty-seven years ago, in December 1979 (published in January, 1980), I wrote a seminal article in “Star and Sky Magazine” — picked up and sent around the world by AP, lauded by Dr. Robert Jastrow (one of the founders of NASA), and Arthur C Clarke and (later) Ted Koppel — scientifically PREDICTING, decades BEFORE NASA: “The oceans of Europa [one of the four “Galilean Moons” of Jupiter] are the PERFECT habitat [beyond the Earth] for CURRENT non-terrestrial life! ... My article only dealt with the specifics of Europa’s habitability, but it foreshadowed the existence of an entirely new CLASS of habitable worlds, DECADES before scientists or NASA missions had discovered them — “Ice-covered moons … housing ‘world oceans’ … protected by a tens-of-miles-thick covering of ice!”
