The seek for life on Mars and the House Tiger King

Jerry van Andel sat alone on the bow of the RV Lulu, a floating junkyard of a ship, because it bobbed towards the waves of the Pacific Ocean. Throughout deck, a crew of scientists bustled round a basket filled with unusual life varieties, wrenched from a mighty crack within the Earth, 10,000 ft under the ocean’s floor.

It was a momentous haul, however van Andel, an lively Dutch oceanographer from Stanford College, wasn’t dancing across the discover with the remainder of the crew. He was deep in thought, propped up on the anchor windlass. A shipmate, John Porteus, seen and shuffled over.

“What’s up?” Porteus requested.

“They do not understand what we have found,” van Andel replied.

It was 1977. Scientists had simply noticed life, thriving, in an oceanic ridge on the backside of the ocean for the primary time. They anticipated a desert; they discovered an oasis. Weird fish swam via darkish smoke billowing out of rock chimneys. Mollusks clung to hydrothermal vents and otherworldly rift worms — 6-foot-tall tubes adorned with blood-red plumage — swayed within the present. 

The RV Lulu’s mission contained no biologists. It wasn’t designed to search for life within the ocean depths. However researchers discovered it anyway. Subsisting on a weight loss plan of poisonous hydrogen sulfide in complete darkness,below bone-crushing strain, the place was really alive. Because the bucket of specimens was raised to the floor, van Andel instantly grasped the importance of the discover: The definition of “life” was being rewritten.

The invention had profound impacts on scientists’ understanding not solely of life on our planet, however of the potential for all times elsewhere within the photo voltaic system. If life may thrive 10,000 ft beneath the ocean, then maybe it may thrive on different planets, too. Planets like Mars.

It appears unlikely the Martian floor, uncovered to the harshness of house, may comprise something however the ghostly relics of existence. The planet is simply too dry. Too chilly. However many consider that not solely does life exist on Mars, however NASA has already found it.

In 1976, a 12 months previous to the RV Lulu’s discovery 10,000 meters under the ocean, NASA landed two beetle-shaped spacecraft, Viking 1 and Viking 2, on the floor of Mars. It was the primary time the company had reached the floor of the purple planet. The landers have been interplanetary laboratories, carrying a collection of devices able to detecting life. Only some weeks after touching down, Viking began performing organic experiments with soil samples from the floor. The primary outcomes that trickled again to Earth have been astounding: optimistic. 

Life on one other planet. 

However was it actually? 

The experiment

Gazing a flickering TV monitor inside NASA’s Jet Propulsion Laboratory, Gilbert Levin waited nervously along with his collaborator Patricia Straat as knowledge from throughout the cosmos trickled in. It was the evening of July 30, 1976, and Levin, a 52-year-old public well being engineer with a eager curiosity in microorganisms, was receiving outcomes from an experiment that had taken place over 200 million kilometers away on the floor of Mars.

Inside a small chamber on the steel hull of Viking 1, a soil pattern was being examined for indicators of radioactivity. The check, referred to as the Labeled Launch experiment, was designed to take Martian soil and spray it with a soup of radioactive vitamins. If there have been microbes within the soil, they’d slurp up the soup and launch it into the chamber as a radioactive gasoline — a response that may very well be detected by devices onboard Viking and, theoretically, show that life existed on Mars. 

On the evening of the experiment, Levin’s son, Ron, was stationed one flooring under the biology crew at JPL. He pressed his resist a plastic window, watching knowledge from the mission being printed onto fanfold paper as Viking slowly despatched outcomes house. He may see, via the window, indicators of a optimistic detection. 

He shortly ran upstairs to inform his dad and the biology crew. Their stress dissipated. At round 9 p.m., the primary full readout had been delivered to the lab, exhibiting a pointy curve on the graph. It was the primary signal life would possibly exist elsewhere within the cosmos.

“I used to be so excited I despatched out for champagne and a cigar,” Levin, now 96, recollects.

Extra experiments have been required to verify what the LR experiment was seeing. Per week later, Levin ordered a second pattern to be taken and heated to 160 levels centigrade — killing any microbes that could be within the soil — after which handled with the radioactive soup. This time the readout confirmed nothing, as anticipated. 

“The pre-mission standards for all times detection had been glad,” Ron says. “Dad discovered microbial life within the soil of Mars.”

In complete, Viking carried out 9 assessments, and all appeared to level to the identical conclusion. However the pleasure was short-lived. One other experiment on the lander didn’t detect natural molecules crucial for all times, main NASA scientists to hypothesize the LR experiment had detected an unknown chemical response happening within the soil. 

“They determined our experiment was incorrect,” Gilbert Levin says. 

The prince of panspermia

Rhawn Gabriel Joseph believes the LR experiment was proper. 

Joseph is an enigma wrapped in a riddle wrapped in a shirt unbuttoned to his abdomen. He’s, in keeping with his autobiography, a well known and acclaimed neurobiologist. He enjoys the ocean, strolling alongside the seashore and mountaineering. His self-published articles argue life has been discovered on Mars and Venus, and propagate another view of life’s beginnings.

That idea is “panspermia.” It holds that life first arose in house and that planets within the photo voltaic system have been “seeded” with microbes carried throughout the cosmos by mud, meteors and particles.

“Panspermia is a type of issues the place all of the biologists are saying, ‘Perhaps it may have occurred, however we haven’t any proof for it’,” says Paul Myers, a developmental biologist on the College of Minnesota, Morris. Myers has refuted the speculation prior to now, resulting in clashes with Joseph and his colleagues, a gaggle he calls “the panspermia mafia.”

Two of panspermia’s greatest proponents are famed astronomer Fred Hoyle, who died in 2001, and his protege Chandra Wickramasinghe. Hoyle helped unravel “stellar nucleosynthesis,” a course of that happens in stars to generate all of the chemical parts within the cosmos and, in collaboration with Wickramasinghe, the pair found the natural materials that makes up cosmic mud. Nonetheless, within the latter components of their careers, the 2 have made controversial claims with little proof to again them up, together with the concept viruses, just like the flu and coronavirus, come from house.

Myers says the educational pedigree of Hoyle and Wickramasinghe gave panspermia an air of credibility within the 1970s, serving to the pair popularize it as a renegade view of the origins of life. However the idea has served as a launching pad for nonsensical, pseudoscientific theories — together with Joseph’s perception that Mars is filled with mushrooms, fungi and lichen. 

Wickramasinghe stays the godfather of panspermia, persevering with to publish on the speculation in books and his personal journals. Rhawn Gabriel Joseph is the inheritor obvious.

Most of what I find out about Joseph comes through his web site, brainmind.com. The positioning instantly invokes the spirit of one other well-known Joseph — the Tiger King, Joseph Maldonado-Passage — with photoshopped photographs of Rhawn posing in entrance of a fiery mushroom cloud studying a novel, black hair puffed atop his head, chest hair peeking out from a child blue shirt. The positioning feels prefer it hasn’t been up to date for the reason that ’90s, a far cry from the wall-of-text curriculum vitaes usually related to lecturers and researchers.

It features a 2,000-word biography the place Joseph particulars his childhood and pursuits rising up, together with the “profound impression” {that a} decapitated rooster, working from side to side, made on him when he was a toddler. One other story recounts his first intimate expertise, at age 13, along with his “deliciously pretty, long-legged” neighbor, a lady he says he gazed at “like a hungry lion gazing steak.” 

These weird asides make approach for educational credentials, explaining Joseph’s adolescence as a neuroscientist within the 1970s when he made “main discoveries” within the discipline,  earlier than pivoting to his present quest, in search of the origins of life. In 2009, he based his personal journal, the Journal of Cosmology (JOC), and, he claims, by 2011 it was “essentially the most learn, most talked about scientific journal on this planet.” 

However JOC is not actually a journal, it is a web site. Its credibility has been routinely known as into query by fellow lecturers and it is served as a bastion for fringe scientific beliefs promulgated by a cabal of renegade researchers since inception. In a single occasion, it revealed claims by ex-NASA scientist Richard Hoover that fossilized micro organism, born in house, have been found in meteorites on Earth. NASA shot down the claims, stating they hadn’t been completely reviewed by specialists.

Joseph’s personal controversial claims about life on Mars have solely sometimes been talked about within the mainstream press and, largely, have been met with suspicion. Probably the most high-profile of those got here in February 2014, when he filed a lawsuit towards NASA compelling the company to look at a “putative organic organism” seen in photographs beamed again from Mars by the Alternative rover. The “organism” was later confirmed to be a rock. 

Since then, Joseph has not often been heard from. Outdoors of a now-defunct YouTube channel, which amassed thousands and thousands of views on its movies about historical historical past, alien life and battle atrocities, he maintains no social media accounts. He isn’t affiliated with any scientific establishments or universities bar the “Mind Analysis Laboratory,” which he established himself in 1986, and “Astrobiology Associates of Northern California San Francisco.” Neither have a web-based presence or a bodily handle and Joseph’s identify seems solely 4 occasions in PubMed, a web-based repository of analysis papers maintained by the Nationwide Institutes of Well being — all earlier than 1989. His educational credentials pale compared to Hoyle and Wickramasinghe.

Joseph stays a mysterious determine, the invisible prince of a ramshackle kingdom. And whereas his contentious views of the cosmos have largely been ignored by NASA and the broader scientific neighborhood, he is lately claimed a breakthrough.

The mushrooms on Mars

The primary interplay I had with Rhawn Gabriel Joseph was through an electronic mail despatched to journalists on April 11 of this 12 months. The topic line was eyebrow-raising: “Life on Mars revealed by Nature/Springer.” Hooked up to the e-mail was a 50-page doc claiming proof strongly helps the concept “mushrooms, algae, lichens, fungi and associated organisms” are current on the Martian floor.

It contained 13 photographs, obtained by NASA’s Alternative rover throughout its time in Eagle Crater. These predominantly featured zoomed and cropped photographs of Martian “blueberries,” spherical rocks composed of hematite, a mineral manufactured from oxygen and iron. The screed “refuted” the notion that these sphericules are hematite and as an alternative posited they could be photosynthesizing mushroom colonies.

The “blueberries” found by Alternative Rover in April, 2004. The blueberries are manufactured from hematite, a typical iron oxide mineral.


The extraordinary claims have been accepted for publication and set to look in a revered, long-running journal, referred to as Astrophysics & House Science. Articles submitted to the journal bear peer overview, a course of permitting different scientists to anonymously consider and validate the analysis.

After I raised questions concerning the veracity of Joseph’s analysis with Jeremy Mould, the editor in chief of Astrophysics & House Science, a spokesperson for the journal confirmed it had investigated the peer overview course of and “revealed issues over its robustness.” Additional peer evaluations have been ordered, however Joseph withdrew the article from consideration, claiming the publishers had caved in to “strain from NASA.” Per week later, he determined to self-publish on one other web site of his, referred to as “Astrophysics and House Science Opinions,” a reputation eerily just like the Springer Nature journal. 

How Joseph’s piece moved previous the peer overview course of and was accepted for publication stays a thriller. The method normally weeds out these explicitly non-scientific claims. Different astronomers and astrobiologists who examined the analysis soundly rebuked its conclusions, citing poor methodology and evaluation. 

Michael Brown, an astronomer at Monash College in Australia, mentioned “there’s some fairly horrible over-interpretation of blurry images,” whereas Gretchen Benedix, a geophysicist at Curtin College in Australia, famous “rising picture sizes to research the objects of curiosity doesn’t change the decision of the picture and due to this fact doesn’t give higher evaluation of the objects of curiosity.” 

Rocco Mancinelli, the editor in chief of the Worldwide Journal of Astrobiology, known as the science and logic “utterly flawed,” and mentioned he would suggest it’s rejected for publication.

A NASA spokesperson advised me “the consensus of the vast majority of the scientific neighborhood is that present circumstances on the floor of Mars should not appropriate for liquid water or complicated life.”

The Martian mushroom speculation fell aside. However six months earlier, Joseph’s theories of interplanetary fungi had already made it to the massive leagues.

The hazard (and the fungi on Venus)

In November 2019, Astrophysics & House Science revealed Joseph’s paper, titled “Life on Venus and the interplanetary switch of biota from Earth.” 

The 18-page doc proposes that Russia’s Venera 13 lander, which spent 127 minutes on the floor of Venus in 1982 earlier than succumbing to excessive warmth, had photographed photographs of organisms resembling lichen and fungi. Like his Mars work, Joseph’s overview offers “proof” of life through grainy digital photographs stretched, cropped and zoomed to oblivion, however notes “similarities in morphology should not proof of life.” 

It is the primary and solely instance of a paper by Joseph to be revealed in a reliable, peer-reviewed journal within the final decade. However following the controversy over the Mars paper, Joseph requested Astrophysics & House Science to withdraw his Venus overview and refund all publication prices, claiming that it publishes “faux articles.” After I raised questions concerning the paper, Springer Nature mentioned the Venus paper “shall be fastidiously investigated following publishing greatest observe.” It is nonetheless out there on-line and has been cited in at the very least one different scientific paper in a key house science journal. On June 23, after elevating extra questions concerning the paper, an editor’s word was added. 

Over the past decade, Joseph and JOC have largely been ignored by NASA and by the scientific neighborhood. Only a few scientists take the alien fungi claims significantly, however Joseph’s work has been highlighted in UK tabloids, RT and lots of well-meaning science information websites since February 2019. Some have touted Joseph’s web sites as “scientific journals” and even confused Joseph’s vainness web site with reliable, equally named journals. One painted Joseph as somebody attempting to “defy the chances.”

And that is the place the hazard lies.

Astrobiology, the seek for and research of extraterrestrial life, is a severe scientific endeavor. NASA has an astrobiology program, and trying to find life is a essential a part of its Mars exploration program. And though the general public appears immune to fanciful claims of fungal spores on Mars or lichen on Venus, they have not gone away. If something, social media appears to have made us extra gullible. As crank, fringe theories begin to collect steam in trustworthy peer-reviewed journals, the general public’s notion of astrobiology can shortly be muddied. 

“I really feel like these guys have simply poisoned the entire discipline,” says Myers. 

Gil Levin, the scientist on Viking’s LR experiment, feels equally. He revealed in Joseph’s JOC in 2010 and has a historical past with Joseph, who nominated the work for a Nobel prize. However in recent times, Levin has distanced himself. “He received to be so erratic that I used to be afraid to be related along with his work,” he says. 

Joseph maintains that NASA has been infiltrated and is “managed by non secular fanatics” opposed to looking for extraterrestrial life. He claims he has ended his profession “by discovering and documenting the apparent proof of life on Mars” and says he can solely look forward to China to research the planet as a result of NASA will “by no means inform the reality.”

The detective

Luther Beegle, a planetary scientist at NASA’s JPL, believes the reality is easy: Viking did not discover life on Mars. However he does say there’s an argument to be made that NASA received the order of the experiments all incorrect.

“They did Viking and received a bunch of outcomes they did not perceive,” says Beegle. He explains how Viking was designed as a biology experiment — however the house company did not have a agency understanding of the Martian soil or environment. It ought to have finished geology and chemistry first. The ambiguous outcomes from Viking’s LR experiment had a substantial impression on NASA’s exploration the purple planet. 

Beegle is a part of JPL’s science division and has overseen work carried out by the Curiosity rover because it arrived on Mars in 2012. The subsequent Mars mission will see him turn into a modern-day Arthur Conan Doyle — solely his Sherlock Holmes is a 10-pound instrument mounted on the robotic arm of Perseverance, NASA’s next-gen Mars rover. 

“Scanning Liveable Environments with Raman & Luminescence for Organics & Chemical substances” or Sherloc, because the instrument is affectionately recognized, will seek for indicators of life on the purple planet, nearly 50 years after Viking’s first experiments, when it launches to Mars in July. The instrument, and its companion digital camera (nicknamed Watson), is able to taking microscopic photographs of Mars and analyzing them. Geared up with a laser it will probably fireplace on the floor, Sherloc is ready to measure chemical compounds current within the soil and rock utilizing a way referred to as spectroscopy.

“We do two sorts of spectroscopy utilizing the identical laser,” Beegle explains. “The primary spectroscopy is Raman spectroscopy, the place we get molecular fingerprints.” 

The Raman spectrometer is ready to detect molecules like salts, hydrocarbons and even nucleotides — the chemical compounds that type RNA and DNA. The opposite spectrometer detects fluorescence and, Beegle says, is designed to look primarily for fragrant organics, extremely steady molecules recognized to be essential in biochemical processes.

If life did exist on Mars, Perseverance ought to be capable of discover it.

Perseverance previous to launch at NASA’s JPL


In February 2021, the rover is scheduled to the touch down in Jezero Crater, a area that was as soon as the location of a long-lived Martian lake. It comprises layers of sediment which will maintain the tell-tale indicators that life as soon as thrived there. Sherloc will map the floor of the crater on the microscopic degree, inch by inch, and the info it gathers will present a window into the previous. 

And Perseverance is tasked with the primary stage of a pattern restoration mission. The rover is predicted to take core samples of the Martian soil throughout its time on the floor. “We will put them in pattern tubes to seal them up, after which we will depart them on the floor,” Beegle notes.

In 2026, a sample-return mission will launch with the intention of nabbing the dropped samples and inserting them on a rocket to Martian orbit and finally again to Earth.

The underside of the ocean and the sting of the cosmos

The existence of deep-sea rift worms was inconceivable earlier than van Andel and a crew of undersea explorers found them, swaying within the heat waters of Earth’s hydrothermal vent system.

And whereas seeing them thriving on the backside of the ocean is proof sufficient of the number of methods life can exist, what makes the worms really exceptional is invisible to the human eye. 

The worms haven’t any mouth and no intestine. They cannot hunt for meals. As a substitute, as Colleen Cavanaugh found in 1981, trillions of microbes inhabit their our bodies, changing hydrogen sulfide and oxygen into vitality, a course of referred to as “chemosynthesis.” The worms rely upon the micro organism to outlive. 

The invention of chemosynthesis within the rift worm helped change our perceptions of not simply the ocean flooring, however the cosmos itself. A 2017 Nature paper described microfossils, as much as 4.three billion years previous, current in sediment from historical hydrothermal vents. If micro organism did come up and survive below such circumstances, why could not they’ve finished so under the floor of Mars? Or within the abyss under the icy shell of Jupiter’s moon Europa? Maybe life may even make the most of the hydrocarbon lakes current on the floor of Titan. These theories are but to be rigorously examined.

We discovered life thriving in locations we by no means anticipated nearly 50 years in the past. We are able to nonetheless be stunned. So we will not, and should not, write off the speculation of panspermia outright. We will not put a line via the concept life is lurking beneath Mars’ barren exterior. The proof suggests it is extremely unlikely, however we will not make sure. 

However, permitting discredited and outlandish claims of mushrooms on Mars or fungi on Venus to be revealed in reliable educational journals places us on a slippery slope. Misinformation spreads shortly and simply. It may actively hurt trustworthy, rational astrobiology analysis. 

There isn’t a NASA conspiracy. We landed on the moon. The Earth is just not flat. Coronavirus did not come from outer house. There are not any fungi on Venus. 

And Mars is just not house to mushrooms.
