ExoLance: Shooting Darts At Mars To Find Life

astroengine (1577233) writes To find life on Mars, some scientists believe you might want to look underground for microbes that may be hiding from the harsh radiation that bathes the red planet's surface. Various NASA rovers have scraped away a few inches at a time, but the real paydirt may lie a meter or two below the surface. That's too deep for existing instruments, so a team of space enthusiasts has launched a more ambitious idea: dropping arrow-like probes from the Martian atmosphere to pierce the soil like bunker-busting bug catchers. The "ExoLance" project aims to drop ground-penetrating devices, each of which would carry a small chemical sampling test to find signs of life. "One of the benefits of doing this mission is that there is less engineering," said Chris Carberry, executive director of Explore Mars, a non-profit space advocacy group pushing the idea. "With penetrators we can engineer them to get what we want, and send it back to an orbiter. We can theoretically check out more than one site at a time. We could drop five or six, which increases the chances of finding something." They will be performing a test run in the Mojave desert to see if their design stands any chance of working.

      The ExoLance folks don't seem to claim that the idea of going below the surface is novel, only the "news" article does that. It is apparent, however, that their ideas for the design are different from DS2:

  4. A lot of ground to cover by Dishwasha · · Score: 1

    It would be nice to see in the article where the enthusiasts intend on dropping their probes. With Mars's landmass being equivalent to the Earth's, that's a lot of ground to cover. It's my understanding that the poles are more likely to harbor life from trapped H2O and CO2 and by their location should receive less solar radiation.

      Maybe they're just starting out with proving the design. From what I've read, all recent mars landing sites have been vetted by years of study by competing teams of researches and finally selected by expert committees based on maximum potential of interesting results.

  9. The Gaia Hypothesis by minstrelmike · · Score: 1

    I think anyone looking for life on Mars should read The Gaia Hypothesis. It was written by an inventor hired by NASA to build devices to discover life on Mars. He researched how life works and realized it (life in general) must control the atmosphere in order to survive for billions of years. The exotic bacteria living in the Antarctic or in Yellowstone Hot Springs still depend on free oxygen and other volatiles created, and maintained over hundreds of thousands of years, by other forms of life. It's a purely scientific proposal, not spiritual or New Agey or anything. Just a new, probably correct way, to understand how life works together to maintain itself.

    1. Re:The Gaia Hypothesis by Immerman · · Score: 1

      And what does that have to do with life on Mars? Clearly if it ever existed in a form similar to on Earth something happened to wipe it out. Life may be necessary for perpetuating the conditions in which life can exist, but it's hardly sufficient. Shut off a planet's magnetic field and life is extremely unlikely to be able to continue making the surface livable. Unless of course it likes receiving large doses of UV and ionizing radiation while breathing vacuum.

      Besides which we're also pretty sure life can render a planet virtually uninhabitable - such as when the blue-green algae first harnessed photosynthesis and virtually eradicated all life on Earth by flooding the atmosphere with highly toxic oxygen.

    In the decades past, it was viewed as harmless...even cute when the little golf-cart like robots crawled across the surface doing their little experiments. But then in 2025, Earth attacked. It was without warning or provocation that the vicious spikes penetrated the community, and this action would not go without swift and formidable retribution. So the ships were fueled and armed, and a vast armada launched into the sky and made their way to seek...not revenge, but justice. The Earthlings, with their antiquated detection systems, didn't even notice the approaching fleet with weapons ready to unleash hell.

    But alas, due to a terrible miscalculation of scale the entire battle fleet was swallowed by a small dog, and no justice was served that day or any other.
