Antarctic Fungi Survive for a Yr in Mars-Like Circumstances on Area Station

Fungi and lichens like these dwelling in probably the most excessive environments on Earth could possibly survive on Mars, based on an experiment carried out on the Worldwide Area Station. The invention is encouraging to scientists who hope to seek out traces of current — and even present — life on the Purple Planet.

The EXPOSE-E platform the place the organisms have been subjected to varied circumstances, and one type of fungi as seen by an electron microscope. S. Onofri et al.

Researchers from the College of Tuscany harvested samples of the extremely-hardy fungi dwelling within the frozen, dry, wind-blasted terrain of the McMurdo Dry Valleys in Antarctica, in addition to equally sturdy lichens from different harsh environments.

The samples have been despatched to the ISS and, on a sealed platform mounted outdoors the station, uncovered to quite a lot of circumstances, considered one of which was designed to mimic the skinny environment and heavy radiation dose of the floor of Mars.

"The outcomes assist to evaluate the survival capability and lengthy-time period stability of microorganisms and bioindicators on the floor of Mars," stated co-researcher Rosa de la Torre Noetzel from Spain’s Nationwide Institute of Aerospace Know-how, "info which turns into elementary and related for future experiments centered across the seek for life on the Pink Planet."
