Searching Salt for Answers About Life on Earth, Mars

13.08.2012
Wichita State University associate professor Mark Schneegurt recently had a paper published in the journal "Astrobiology."

His paper focused on bacteria that live in environments that are salty, but not with sodium chloride – the kind of salt we're used to. It has to do with magnesium sulfate, also known as Epsom salt.

Researchers have discovered that not only is there evidence of liquid water on Mars, but the planet is also rich with magnesium sulfate.

One of the questions Schneegurt is seeking an answer to is whether microbial life on Earth can grow at these high concentrations of magnesium sulfate.

"This impacts our understanding of what ancient or current life on Mars may be like," he said. "What single discovery could have a greater impact on our philosophy and culture, how we view ourselves in the universe, than finding life on another planet?"

Finding life on Mars?

Other questions his paper and research deal with include:

•Are there any microbes on Earth that may be able to survive on Mars?

•How can we protect our search for life on Mars by preventing terrestrial microbes from infecting Mars when a spacecraft lands?

•Are epsotolerant microbes a glimpse at what life may have been like – or is like – on Mars?

Schneegurt said it's been hypothesized that living in high magnesium sulfate may be the hardest part of living on Mars, but his contention is that it's not as difficult as some scientists think.

Part of his research also focuses on searching for life in lakes with high magnesium sulfate levels, as well as searching for similar life in spacecraft assembly facility clean rooms.

Schneegurt and his research team have been working at Hot Lake in Washington and Basque Lake in British Columbia, and have isolated hundreds of microbes that grow at high magnesium sulfate concentrations. The goal is to characterize those microbes and see if they can also find them in spacecraft assembly facilities.

"If we bring life with us and it can grow on Mars, this makes it more difficult to be sure that any life we find on Mars actually comes from Mars," he said. "It also will impact our efforts in forward planetary protection, where life from Earth contaminates Mars when a spacecraft lands."

Is this research important? NASA and the astrobiology community think so, Schneegurt said.

After receiving a small Kansas NASA EPSCoR (Experimental Program to Stimulate Competitive Research) grant in 2009, Schneegurt received a NASA grant through the ROSES program and the Planetary Protection group at JPL (Jet Propulsion Laboratory).

Schneegurt said not only can his research teach us more about life on Mars. It can teach us about our own planet.

"Our work has relevance to the origins of life on Earth, since life may have arisen from a briny tidal pool." he said.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
