Dear Vladimir : I congratulate you on the recent news on your team’s discovery of living plankton on the outside of the ISS. I would be interested in your comments on the following questions :
1. Can your team explain in more detail the hypothesis that the diatoms rose through the atmosphere to 400 km? How?
2. What are the types of Eukarya already identified ?
3. On any diatoms : how do you believe they are surviving – with the extreme cold, the absence of oxygen and the intense cosmic rays?
4. Have you done (or do you plan to do) RNA/DNA analysis on the diatoms?
5. Are these diatoms all alive, or are some also fossilized or even dessicated?
6. Did your team also do tests to search for viruses, bacteria and archea (alive, dessicated and/or fossilized)?
7. how was the contamination control experiment designed? And did you eliminate contamination this way?
8. will you be returning samples to Russia to conduct more detailed analysis including using the latest virus and bacteria identification tools?
I believe this discovery, in itself, is already a huge step forward. Just simply the detection of living diatoms outside the ISS is profound.
The fact that we can return samples to earth for in-depth analysis by the latest virus and bacteria identification systems; and that the diatoms themselves can be tested back on earth for isotopic signatures with electronic microscopes, leads me to believe that within a year this “mystery” will become much clearer.
My expectation is that at that point the Hoyle-Wickramasinghe Model of Panspermia should take yet another step forward as the mostly likely hypothesis for the paradigm that Life is a Cosmic Phenomenon (ie that life exists across the galaxy and universe).
Yours in science

Further thoughts on the ISS discovery news. FYI – From WIKIPEDIA : Diatoms are a major group of algae, and are among the most common types of phytoplankton. Diatoms are traditionally divided into two orders:
Richard Hoover is a world expert on diatoms and is seeking further information from the Russians to determine the classification of what has been found.
Question #1 : Are diatoms Eukaryotes? Yes, they are because they have at least one nucleus. So what has been found on the ISS seems to have been identified as large size diatoms.
Question #2 : did they also test for bacteria or archea (or even viruses?) ? Don’t know.
Question #3 : could a particle the size of a diatom rise up from earth to the ISS where there is no air to even “lift” the diatom? There is no way that a particle as large as a diatom could have been carried up to the the space station . It is a defiance of physics. As Richard Hoover wrote this morning :
The famous Russian Cosmonaut Vladimir Solovyev just announced that diatoms and other marine plankton were discovered alive on the outside of the windows of the Russian Section of the International Space Station—surviving in the hard vacuum, thermal, and radiation environment of space. This is consistent with the detection of diatoms embedded in the interior of the Polonnaruwa meteorite stones described in a paper with Chandra Wickramasinghe and Jamie Wallis published last year (2013) in the SPIE Astrobiology Volume. In 1986, the late Sir Fred Hoyle and I proposed in a paper in the Journal Earth, Moon, and Planets that planktonic diatoms could be spewed into space along with water and ice ejected from Europa or from comets and transferred to The Earth.
I do not think there is any possibility they could have been carried to the Space Station by air currents as was suggested, since air currents do not work in a vacuum.
Some critics may say that the diatom found on the space station is too closely related to well-recognised species of diatoms that exist on the Earth. An origin of such an organism in a comet, they could say makes no sense from an evolutionary biology standpoint as life strives always to be ideally adapted to its particular environment.
The reason why the space incident diatom is similar to a terrestrial diatom is that they both came from space. All life comes from space in the first place, and continues to do so. Life on Earth is an expression on the Earth of a Darwinian evolutionary scheme that has taken place over a vast cosmological scale. Not so long ago it would have been thought impossible to find the same species in opposite hemispheres of the Earth. The connected biosphere of the Earth has now to be regarded as being connected to a vast cosmological biosphere within which frequent exchanges of genes and genotypes have established a unity of all life in the cosmos.
I BELIEVE THIS IS STAGGERING NEW EVIDENCE FOR ONGOING PANSPERMIA.
PS. I thought it a good time to dig out two old papers on “Diatoms in Space” which I make available FREE here to my BLOG Readers.

The Daily Mail today reported : “….that traces of plankton and other microorganisms have been found living on the exterior of the International Space Station (ISS), according to Russian space officials. They claim the plankton were not carried there at launch – but are thought to have been blown there by air currents on Earth. Incredibly, the tiny organisms were found to be able to survive in the vacuum of space despite the freezing temperatures, lack of oxygen and cosmic radiation“.
I think a quick review of this discovery is in order.
First of all let’s review the height of the ISS. The International Space Station, with ESA’s Columbus laboratory flies 400 km high at speeds that defy gravity – literally.
This is 8 times higher than the very TOP of the stratosphere. or 40 times higher than the top of Mount Everest. I believe there is no known process where any viruses, bacteria, archaea or even eukarya have been proven to have been raised to anything like that height – even considering volcanos.
Explosive eruption plumes such as those generated at volcanoes like Mt. St. Helens or Pinatubo can reach high into the atmosphere. The highest Mt. St. Helens plume on May 18, 1980 reached about 31 km (101,700 feet), and the highest Pinatubo plume got as far as 45 km (147,600 feet). But we know the ISS is at 400 km.
We do know that rare cloud types have occurred in the mesosphere. But that’s about the highest we are aware of. And they are very, very rare.
The fact is, no matter how we all try to play it down, this is a stunning discovery. And it is consistent with the Panspemia Hypothesis. Certainly this is evidence that will challenge mainstream science as it continues “the difficult endeavor of seeking the signs of life”.
The way these microbes have survived against extreme cold, cosmic rays, and lack of oxygen is very surprising even for myself. I must admit I am glad it is the Russian Scientists doing this analysis.
Is this the result of contamination from countless EVA’s and over 80 ISS flights each one delivering people and equipment with the people being the biggest source of viruses and bacteria given our (now much better understood) symbiotic relationship with these microbes. It is almost certain that the level of contamination man has caused in the ISS and space is much greater than science is prepared to acknowledge.
But perhaps it is too early to say this is the very first discovery of ET life. But it will be very interesting to see the RNA/DNA analysis.
I will be toasting Sir Fred Hoyle this evening. Those of us who have calculated that “Life must be a cosmic phenomenon” know this brings us ever closer to the day when science lays to bed the theory that life is unique to the Earth.
This is almost as exciting as the recent discovery of bacteria which live deep below the earth and feed directly on electrons. More on that next week.
About the double nature of the comet as recently discovered. It is anybody’s guess what the surface will reveal.
In spite of the uncertainties inherent in the present calculation, it is possible to interpret the surprisingly large outflow of water observed from the Comet 67P/C-G (Churyumov-Gerasimenko) on June 6, 2014, when the comet was between Jupiter and Mars, as being indicative of biology. Although microorganisms in comets are likely to be in a frozen dormant state at aphelion, a sporadic resumption of metabolism will occur near perihelion if subsurface melting can take place. Metabolism builds up subsurface gas pressures of thousands of atmospheres, which is enough to cause cracks in the surface crust releasing gas and dust. Such melting could occur due to increased solar radiation or, on occasion when impacts of smaller bodies transfer kinetic energy that can be converted to heat. Comet Hale-Bopp showed sporadic activity when it was outside the orbit of Jupiter. We can argue that this activity in Comet Hale-Bopp, as well as the new evidence from Comet Churyumov-Gerasimenko, point to the resumption of bacterial activity (8).
As we await the descent of the Philae lander onto Comet Churyumov-Gerasimenko with bated breath, there would inevitably be many surprises in store. The recent discovery that the comet has a “double” structure and is probably a contact binary may be the first of many to come. It is to be hoped that more indirect evidence of biology will be forthcoming as the ROSETTA mission draws to a conclusion this year.
Dirk Schulze-Makuch : The cyanobacteria, diatoms etc you analyzed in the meteorites are ideally adapted to life on Earth, to life on a planetary surface. So, assuming you are correct and they indeed come from space, where is the source? An origin of these organisms in a comet would make no sense for me from an evolutionary biology standpoint as life thrives always to be ideally adapted to its environment.
Richard Hoover : There are skeptics who claim that even though many of the remains I have found in these meteorites are recognizable as heterocystous cyanobacteria, diatoms, acritarchs, hystrichospheres and other known extant or extinct life forms, they must be modern bio-contaminants. This argument conveniently neglects the fact that the EDAX data consistently show the remains have nitrogen levels below the instrument detection limit and hence died millions of years ago-long before these meteorites were observed to fall to Earth.
Chandra Wickramasinghe : The reason why fossil microbes and diatoms are similar to their modern terrestrial counterparts is that they all came from space in the first place, and continue to do so. Life on Earth is an expression on the Earth of a Darwinian evolutionary scheme that has taken place over a vast cosmological scale. Not so long ago it would have been thought impossible to find the same species in opposite hemispheres of the Earth. The connected biosphere of the Earth has now to be considered connected to a vast cosmological biosphere within which frequent exchanges of genes have established a unity of all life in the cosmos.
Dirk Schulze-Makuch : I find it very strange that extraterrestrial life would look so similar, or should I say identical to cyanobacteria, diatoms etc as Richard claims. This does not make any sense to me and is in my view so implausible that any contamination such as pointed by John is much more likely. I just discussed this matter with Alberto Fairen and he thinks alike but thought about another possibility: Could Richard’s bugs be terrestrial life that has been for billions of years away from Earth because it was ejected in primitive impacts?
William E. (Bill) Smith : Today the Rosetta Mission approaches COMET 67P now just 100 km away. 67P’s orbit is in the plane of the galaxy and is “part of our solar system” (ie it is a Kuiper belt “comet” ) with an orbit of just 6 years. Contrast this with COMET ISON, which unlike 67P (Rosetta), was a parabolic comet. I.E. ISON’s orbit period is unknown (> 100,000 years). It entered the plane of the galaxy at a steep inclination FYI – approximately the same as the angle of the solar system (the ecliptic) to the galaxy’s plane. It is now accepted mainstream science that the solar system is part of the Sagittarius Dwarf galaxy which is colliding with the Milky Way. I believe (educated by conversations with Chandra ) that “long period” comets like ISON are the REAL source of original life in our Solar System. Ie ISON was “sling shot” in towards the SUN from an adjacent star. Short period comets which includes both Halley’s Comet with its 80 year orbit and Rosetta (67P/C-G) with its 7 year orbit, might well (and likely do) contain dormant viruses, bacteria and even diatoms (as found by Richard Hoover). These “seeds of life” were catapulted into local inner space from major collisions like the asteroid (or comet) which caused the end of the dinosaur era.
But I believe it is the long period comets like ISON which carry the real interesting and original “seeds of life” from other solar systems across what Chandra Wickramasinghe calls the “vast cosmological biosphere”.
And at this moment in time in August 2014, I wonder how rigorous was our sterilizing of the Rosetta Mission back in 2004. The Philae Lander will arrive on Comet 67P/C-G this November (2014) carrying untold numbers of dormant viruses and bacteria from earth, just waiting to be reactivated by the water that is already proven to be on the comet – proven using the remote spectroscopy by the ALMA telescope in Chile.
Chandra Wickramasinghe : Bill – although you may well be right, it is not a time for negative thoughts. NASA ask us to emphasize that the “search for life is a difficult endeavour”. To that we all agree. BUT what we are now expecting to find (on 67P, MARS, Titan and Enceladus) is that life is found “everywhere”. Do we really care “where it came from originally” or even if we inadvertently delivered it.
Time to agree that “Life is indeed a Cosmic Phenomenon”.
I have collaborated with Gensuke Tokoro of the Institute for the Study of Panspermia and Astroeconomics, Gifu, Japan to produce this paper.
A major paradigm shift with potentially profound implications has been taking place over the past 3 decades at a rapidly accelerating pace. The Copernican revolution of half a millennium ago is now being extended to place humanity on the Earth in its correct cosmic perspective – an assembly of cosmically derived viral genes, no more, no less, pieced together over 4 billion years of geological history against the processes of Darwinian natural selection. The evidence for our cosmic ancestry has now grown to the point that to deny it is a process fraught with imminent danger. We discuss the weight of modern scientific evidence from diverse sources, the history of development of the relevant ideas, and the socio-economic and historical forces that are responsible for dictating the pace of change.
In summary we conclude : A paradigm shift of the kind we have discussed in this article may be stalled for seemingly rational reasons based on either prudence or pragmatism:
I am planning a BLOG post in the fall which offers a positive vision for the way forward.
The biological big bang with water oceans 2 million years after the cosmological event is easy to explain by Rudy E. Schild and Carl H. Gibson’s Hydro-Gravitational Dynamics (HDG) cosmology. Old cosmology based on cold dark matter makes life virtually impossible (CHG). See more here :
July 2014 : I am sure you already know that Rosetta will be the first mission in history to rendezvous with a comet – with Comet 67P/Churyumov-Gerasimenko (67P/C-G). I risk the ire of other astronomers by referring to the COMET as COMET ROSETTA only because the latest name 67P/C-G just does not capture my imagination. I think CNN and BBC need an easier name.
In July 2014, the Rosetta Mission is already approaching the Comet as it orbits the Sun. With what promises to be a stunning implementation of ESA’s daring vision, in November 2014, the mission will actually deploy a landing vehicle onto the crusted surface of the COMET.
Last year, in 2013, the whole world watched another COMET, COMET ISON. We were spell-bound as the Comet headed in towards the SUN. Through coverage by CNN and the BBC (and eventually all the world’s media) the event attracted global attention. We all recall that ISON, in the end, failed to amaze, as it was destroyed by the gravity of the Sun on Thanksgiving evening 2013.
But this time, the almost certain landing promises to deliver wonderful TV footage that the world’s media is expected to cover for many hours if not days or weeks. Rosetta will arrive at the comet in August 2014. The Philae lander itself will be finally be deployed in November 2014.
Humans have always marvelled at landings on other bodies. First there was the wonder of landing on the MOON ; then there was the thrill of MARS CURIOSITY landing on Mars. But the concept of landing on a Comet is beyond most people’s imagination. I believe it will be breathtaking television. The movie “Gravity” educated every girl and boy on the planet about the International Space Station and the challenges of orbiting the Earth
But now childrens’ minds will be expanded as they experience landing on a body which is orbiting the Sun. I promise you the build up on TV will be amazing, as first Rosetta comes very close to the comet in just a matter of weeks. We will then share the thrill of flying alongside the comet. This will continue from August until November. And then the “reality show” culminates with this most amazing landing which I predict will happen in “prime time” in the USA.
ROSETTA’s route to the comet 67P/Churyumov-Gerasimenkohas (C-G) has been a long 10 year journey. I was fortunate to be one of the original principal investigators. But I admit to great disappointment when I realized that Rosetta was not going to carry “life detection and verification” equipment. If truth be told, in those days we did not really understand the extraordinary role of viruses in the evolution of life on Earth. Symbiogenesis has revolutionized our understanding of life and it makes me even more confident that the original theories of my now passed collaborator Sir Fred Hoyle, and myself, will eventually be confirmed. Just as 2013 was the year Panspermia became mainstream science, so 2014/2015 could well be the time that we finally discover undebateable evidence that “Life is a Cosmic Phenomenon”.
So now in 2014, as the Rosetta space craft approaches the Comet 67P/CG (Churyumov-Gerasimenko), our knowledge of viruses and bacteria and especially symbiotic life, has grown substantially. We also recognize that NASA has refocused from “the search for water” to “the difficult endeavor of searching for the signs of life”. The ESA/NASA Rosetta team are guaranteed to be employing all the very latest tools we have at our disposal using remote spectroscopy by the wonderful Chile-based ALMA telescope. Will we be able to detect life or even the signs of life?
I am pleased to share my predictions with you, and have written a short paper for your enjoyment and understanding. The paper is adapted from a review invited by the open access journal The Journal of Astrobiology and Outreach (JAO).
May your life too be a Cosmic Phenomenon
