The opposite two expeditions revisited these similar websites within the useless of winter, when the lakes had been frozen over and icy layers fashioned. These environments could possibly be much like these on moons like Europa and Enceladus which might be thought to cover oceans of salty liquid water below their ice crusts. If life exists wherever else within the Photo voltaic System right now, it might properly be on moons like this, making the hypersaline lakes nice targets in analog research of habitability.
Up to now, the crew has collected greater than 400 distinctive samples of lake ice, salt, brine, and sediment. These samples are being analyzed for microbial life, natural content material, and ecological construction to raised perceive how the physics, chemistry, and biology of those excessive environments work together.
A serious objective of the analysis is to pinpoint the place the richest microhabitats exist inside these excessive lake methods. One other objective is to determine the sorts of biosignatures that we would be capable of spot once we go to these locations. Basically, the analysis helps us higher perceive the place and easy methods to search for indicators of life on different worlds.
One outcome Buffo’s crew has discovered to date is that hyperspectral drone imagery has been helpful in mapping key options like brine swimming pools and mineral ridges in lakes like this. This would possibly help using flying spacecraft like NASA’s Ingenuity or Dragonfly helicopters to scope out the place to go looking extra totally for indicators of life.
By testing out methods, instruments, and theories right here on Earth, Buffo and his analysis crew are serving to ensure that once we exit to seek for life on different worlds, we’re as ready as we might be.
