Our Search for Extraterrestrial Life

With Mars hosting the Curiosity Rover for the past three months, there’s been a lot of public excitement around space exploration. One of many goals of space exploration is  to find life on another planet. There are groups like SETI that are focusing their attention and research on extraterrestrial life, “The mission of the SETI Institute is to explore, understand and explain the origin, nature and prevalence of life in the universe.” SETI’s been around since 1984, so the search for extraterrestrial life is not a new concept. Some may say that the purpose of finding life on another planet is to keep our options open for a new home when Earth is no longer habitable. Others, like SETI, hope to learn about the nature of life itself throughout the universe. Either way, the search is on. So, how’s that going for us?

SpaceX and NASA are taking steps towards putting humans on Mars. One of the problems that idea poses is that our astronauts will contaminate any potential life that could be on that foreign planet. Humans have evolved among 100 trillion microbes that could very well latch on to Martian organisms upon arrival to the planet- posing unknown risks to the planet and the organisms on it. There is a lot to consider in terms of safety not only for the sake of our astronauts, but also on behalf of the foreign planet and its environment and/or organisms.

Due to the large number of considerations space exploration forces us to ponder, space startups are struggling to provide VCs with enough comfort to overlook the numerous risks that space exploration poses to spacepreneurs. Private space ventures are the most active ones. Amazon’s Jeff Bezos, Microsoft’s Paul Allen and PayPal’s Elon Musk have all spent millions in developing and enhancing space travel technology. Elon Musk is having the most luck lately, with SpaceX’s contract with NASA for 12 expensive trips to the ISS. NASA’s Curiosity Rover is also doing well, collecting enlightening samples that are (as far as I can tell) very transparently reported to the public. One of the main goals of the rover is to find some sign that life on Mars is or was possible.

How are we going about this search for extraterrestrial life anyway? How do we know what we’re looking for? Well, we’ve been searching, primarily, for a certain kind of living organism on other planets: carbon-based organisms, and those comprised of water. “The presence of water, organics, and energy represent three concurrent indicators in the search for signs of life as we presently understand,” says NASA’s 2012 Exploration Goals and Destinations Report. The report goes on to say, “The detection of water in a wide variety of solar system locations, including the Martian surface, the moons of the giant planets, Earth’s Moon, asteroids, and comets — has broadened our search for indications of life. The diversity of these locations and the known complexity of biotic and pre-biotic chemistry means that advanced instrumentation is required, and that direct examination of samples, either returned to Earth or in situ by robots and humans, is needed to produce definitive results.”

We’re spending a lot of time and energy on searching for signs of life “as we presently understand,” but can other elements be the building blocks of life for extraterrestrial creatures? Yes. It’s possible. In fact, we already know that several small life forms use arsenic to generate energy and facilitate growth. Chlorine could facilitate life, and sulfur has already proved to be a hospitable environment for some bacteria. Stephen Hawking notes that carbon seems more favorable because of its chemistry, but it’s not the only solution, “One possibility is that the formation of something like DNA, which could reproduce itself, is extremely unlikely. However, in a universe with a very large, or infinite, number of stars, one would expect it to occur in a few stellar systems, but they would be very widely separated.”

This means it would probably be beneficial to spend more time searching farther away from Earth for these commonly understood life-creating elements, if they are indeed very widely separated throughout the universe. However, the most common agreement among bioscientists focusing on carbon-based organisms seems to be that Earth is in a uniquely “sweet” spot in the universe and thus, it is more beneficial to search around our general planetary location. In any case, whatever the reason, whatever the method, the search is on for extraterrestrial life. It’s exciting, but there are several consequences to consider before we start swapping organisms with other planets, which is probably ultimately going to be a choice we will have to face in the future.

In fact, just to cover all of our bases, we should prepare ourselves for a day when we find out there is life on other planets and they are intelligent. What do we do then? Study it? Will we need to convince it to let us study it? What if it wants to come live on our planet?

What Mars Means to Earth

I am a fan of Mars. I think people will live there one day. Really. So I was quite excited to watch the NASA/JPL live feed last night of the landing of Curiosity, the largest craft ever soft landed on another planet, and to share vicariously in the moment. Watch it here.

Then today my friend and colleague Mark Anderson, of Strategic News Service (I serve on the advisory board for his annual conference, Future in Review), published the following Special Alert about the landing. In Mark’s classic and hard-hitting way he tackles what the accomplishment should mean for science, and politics.

Here is Mark Anderson…

To Our Members:

As you are no doubt aware, at 1:38 a.m. this morning, NASA and the Jet Propulsion Laboratory/Caltech succeeded in landing a one-ton rover named Curiosity on the surface of Mars. This effort required years of scientific, technical and engineering preparation, resulting in a novel multi-stage process for getting heavy equipment onto the red planet, rife with steps which, if any failed, would likely cause mission failure.

The landing occurred without a single problem, including minutes during the critical last phases of the flight when the spacecraft was out of communications with Earth and ran autonomously.

While this effort will no doubt have a great impact in improving our knowledge of the Mars geology and surface, including habitability for future human missions, and perhaps information on past life in the targeted crater, there is a deeper meaning to this effort:

Science is reality.

At a time when a large and increasing fraction of the U.S. population does not “believe in” science (i.e., objectively provable reality) – or, worse, has bought into the idea that science is just one choice on the reality menu – NASA has again given concrete reason to understand that science works, and that science is not an option, not a theory, not a menu item, but instead represents the finest efforts of human minds in understanding, and addressing, objective reality.

Those on Earth who currently think that science is a political football should take note: not only are you endangering your own reputation, you are endangering the welfare of your constituents, and today, of the planet itself.

Any person or party which mocks science should be considered for what he or it is: a threat to the welfare and future of us all. Under the influence of political propagandists, misled religious zealots, and truly dangerous television and radio empires (such as Fox (Not) News and Rush Limbaugh), too many people today have been led to believe that science is in some way an option to opinion.

Science is as optional as gravity. Ignorance is the only real option.

It is time for the U.S. to catch back up to the world in this matter, and recognize the value of scientific study and theory, the use of scientific consensus in guiding public policy, and the wonders that we can achieve when we abandon self-aggrandizing political fantasy in favor of objective scientific knowledge.

We should use this marvelous achievement to create a new cultural change in the United States, returning us to the group intelligence of past eras, when no one doubted that an experiment, done with the same result several times, demonstrated an objective truth. Not an opinion, not a religious position, not a political chip, but another addition to human scientific knowledge.

The world owes much to the people of NASA, of JPL, and to the taxpayers of the U.S., who have achieved the most important step in space exploration yet attempted. This was done by a willing and informed government, working with private contractors, paid for with taxes. It stands as one of the greatest of tributes to human intelligence yet achieved, shoulder to shoulder with decoding the human genome.

I highly recommend that you take a moment to watch the scene inside JPL headquarters in Pasadena, as Curiosity makes its way safely to the Martian surface. We owe a great deal to those pictured in their moment of triumph, and citizens of the U.S. owe it to themselves, if they wish to remain a great nation, to put a rapid end to the rise of ignorance in their country which threatens scientific endeavor, and the acceptance of scientific findings.

Our thanks go out to all of the people who, using Science, Technology, Engineering and Math, just flew a car-sized laboratory across the solar system, landed it safely at the end of four lines under a crane under a rocket under a parachute, to bring us yet more scientific knowledge about the world.

It is time for all Earth inhabitants to recognize the value of science. In doing so, we will find common ground for agreeing on other important things.

Here is the video

Long live Science.

Sincerely,

Mark Anderson
CEO, Strategic News Service
