The Case Of The Hitchhiking Microbe


What, exactly, does NASA hope to accomplish if astronauts really do set their boots on the surface of Mars? One thing they hope to discover are clues to the origins of life on Earth. The gringa asks, “What exactly does that mean?” It means that NASA is considering the theory of “panspermia” and is exploring outer space to see if stellar evidence proves this theory to be true.

Panspermia is nothing new.  As far back as 5BC scientists were considering panspermia as the explanation for how humans came into existence here on Earth. In 1871 it was officially proposed in the scientific community of that day. Panspermia posits that it is possible for life to planet hop, possibly even hop among star systems, and seed the planets it visits with life. In a nutshell, that would mean that the primitive biological material that evolved into the original ancestors of humans was not created here on Earth, but, rather, were alien hitchhikers who made their way here on cosmic fragments.

NASA’s exploration policy is to “follow the water” because it is necessary to produce life as we know it. Water is found throughout the universe, just not in the form we need, liquid. It’s usually frozen. However, wherever there is frozen water, perhaps, in that planet’s history, it was once liquid. And, if so, perhaps that is where human origins can be found if the panspermia theory is true, that life exists in the universe and can travel via meteors to other planets and eventually develop on other worlds where the environment is sufficient to support its development.

Since Mars was a warm world with water long ago, the necessary ingredients for life as we know it, it makes it a logical planet to explore for evidence of panspermia. The exploration and data collected so far from the rovers and satellites studying Mars have been limited to studying the surface of the Red Planet. No evidence has been found on the surface. It is possible, however, that important evidence could be buried beyond the reach of the rovers’ digging capabilities or a satellite’s imaging. That is why it is important to get some human explorers out there.

What would the implications be if Earth-like microbes were discovered on Mars? Every human would first want to go have a very long look in the mirror and then a very long look up into the heavens and ponder the concept. NASA, however, would not be surprised. NASA has already conducted studies on over 130 meteorites from Mars and determined that none contained any microbial evidence despite the fact that some claims to the contrary were made. NASA understands the serious repercussions that would occur around the world if such a discovery is made and we can trust them to report the truth without any hype. NASA takes scientific truth seriously.

They even have a program established that studies the effects such discoveries might have throughout the world. They understand that an announcement that extraterrestrial life exists will have serious philosophical, religious, legal, ethical and cultural implications that will impact people all over the world.

Despite NASA’s interest in this theory and their willingness to explore space with the idea in mind to search for supportive evidence, they are also realistic about its probability. They believe that it is probably unlikely that life as we know it on Earth was seeded from Mars origins. However, because science is not about “probably”, they must continue the studies until the theory can be proven or disproven.

There are some scientists who do believe that Mars was an ideal place for life to have existed at some time. They believe that since such life would have existed long before life on Earth ever existed, it is then not unreasonable to consider the possibility that microbes traveled to Earth on a meteorite and introduced life here on the Blue Planet.

One reason some scientists support the idea of panspermia via Mars is because Martian meteorites contain the precursors to RNA, boron and molybdenum. In fact, they contain more of these two elements than what is found in early Earth. And why does that matter? RNA is a molecule that plays a critical role in regulating genes and its presence is necessary for all life forms as we Earthlings know them. So, if an old rock from Mars contains such a molecule, it only stands to reason, at least from an Earthling perspective, that it existed on Mars for the purpose of regulating the genetic codes of some Martian life form.

Another Martian discovery that further supports the belief that life once existed on Mars has to do with phosphates. It has already been established that Mars has provided evidence of the presence of RNA. In order for RNA to form, phosphates must be present. Well, not only does Mars have phosphates, but Martian phosphates dissolve in water much better than Earth’s phosphates. The logic then goes that since life as we know it here on Earth originated in water, Martian conditions were even more friendly to the aspect of life forming than conditions on Earth. So, if it could happen here, it most certainly should have happened on Mars.

So, basically, the theory goes that about 4 billions years ago a comet or meteorite of Martian origins blasted through our galaxy and slammed into Earth. Now this could have been an accident or, according to “directed panspermia” theory, a deliberate action by an intelligent civilization.

Historically panspermia has been considered “fringe” science. However, it is now gaining new consideration in light of the Mars mission. In fact, in 2013 Professor Chandra Wickramasinghe of the University of Buckingham claims to have discovered fossilized remains of organisms in meteorites found within Earth’s atmosphere. This proves that it is possible for primitive life forms to survive the intense heat of entry into Earth’s atmosphere and make its way to Earth’s surface. He believes it is possible that the entire Milky Way Galaxy could have been teeming with life at one time long, long ago. He also believes that organic, possibly even living, stellar material is constantly being exchanged throughout the cosmos through meteoric impact.

So, the gringa awaits the exciting mission of boots on the ground on Mars. I eagerly await the drill, baby, drill action that will delve deep below the dusty surface of the Red Planet. I can’t wait to find out what may lie beneath the frozen crust of the vast Martian ocean. Scientists believe the Martian seas are not frozen solid. Could a Martian “Nessie” be swimming about waiting for visitors to come feed her a few breadcrumbs? It very well could be. And, she could be our distant cousin.

Isaac Newton By The Sea


NASA recently reported images of an X-ray tail (or, ribbon) of galactic gas. It has broken cosmic records with the extraordinary length of 250,000 light years. The published images are a composite from combined data that originated from the Chandra orbiting observatory and the Isaac Newton Group (ING) of Telescopes that are located in the Canary Islands of Spain.

ING consists of two telescopes. One is named William Herschel (WMT) and the other is Isaac Newton (INT). They are located on a seaside cliff of La Palma Island and command a breathtaking view of the sea as well as the night sky. Isaac Newton began serving astronomers in 1984 and William Hershel in 1987.

ING is a collaborative effort of scientists representing the United Kingdom, the Netherlands and Spain. Their goals in serving the world community of astronomers and space related science is to provide world class telescope operations and programs that aid in research efforts. To encourage innovative methods in science and research, ING welcomes projects that involve novel instruments as “visitors”.  ING is committed to fostering original thinking as well as strongly supporting classical observing.

The Isaac Newton Telescope is open for visiting observers. New instruments are now being enjoyed with funding to provide more. One new instrument, the PAUCam, is a state of the art imaging device that creates prime focus capabilities for the William Hershel Telescope. A wide-field multi-object spectrograph is being developed for William Hershel and expected to become operational in 2017. This instrument will be part of a five year study to help understand how the Milky Way was “assembled”.

WEAVE is the name of the spectrograph developed for William Hershel. WEAVE was designed and built by a consortium of institutes from the UK, the Netherlands, Spain and France. Although visitors will still have access to observe the heavens through William Hershel, much of the telescope’s time will be devoted to the study of three particular projects: 1. The archaeology of the Milky Way; 2. The evolution of the galaxy; 3. Dark energy and its nature. These projects create wonderful opportunities for the UK, the Netherlands and Spain to make important scientific contributions to the world community’s knowledge of outer space.

Resident student programmes are available with ING. Over the past decade, forty students have served in the position of INT support astronomers and have gained valuable hands-on experience and technical skills. In fact, since 2009, 53 PhD theses have been based on ING data. Announcements will be made in March 2016 about the details of the 2016/2017 programme which offers astronomy and astrophysics PhD’s, MSc’s. INT welcomes students who are interested in any field of astronomy or astronomical instrumentation.

Students stay in flats provided by ING and receive a modest monthly stipend. These are cozy abodes within walking distance to the observatories, however, ING also provides transportation back and forth. For one year students will have the opportunity to participate in supportive roles in the work performed by one of the world’s most scientifically productive and versatile telescope groups. They will become part of the professional astronomical family of La Palma.

To qualify for admission to the programme, students must be a European citizen or European student resident. Enrollment in an astronomy PhD or MSc program or in the final year of undergraduate astronomy or physics course is required. English is a must, Spanish is a plus. It is also helpful to have some experience with Linux/UNIX operating systems as well as IRAF astronomical data reduction software. While participating in the program, expect to work 37 hours weekly, day or night, as well as weekends and holidays. A valid driving license is expected as well as being able to pass a medical examination.

Four positions are available. Students report for duty in September. During the one year of service, students have a 25 day leave allowance.

Qualified students who are interested should prepare a cover letter presenting experience along with any other pertinent information to be considered. Two references are required. Applications must be received by May 1 via e-mail or snail-mail. E-mail contact is Ovidiu Vaduvescu, INT studentship program manager, ovidiuv@ing.iac.es. Snail mail contact info:

And, if you are unqualified, like the gringa, but still interested in what goes on at ING, their website has an interesting feature that the gringa really likes. It’s called “Ask an Astronomer!”. You simply fill out the e-mail form and submit. It’s not just any ol’ email form, however. It also has lots of other information to pick and choose from. Click “send” and wait for an amazing scientist to school you on what you want to know.
