As NASA’s rover Perseverance explores the floor of Mars, scientists attempting to find indicators of historical life on the distant planet are utilizing information gathered on a mission a lot nearer to residence at a lake in southwest Turkey.
NASA says the minerals and rock deposits at Salda are the closest match on Earth to these across the Jezero Crater the place the spacecraft landed and which is believed to have as soon as been flooded with water.
Info gathered from Lake Salda might assist the scientists as they seek for fossilised traces of microbial life preserved in sediment thought to have been deposited across the delta and the long-vanished lake it as soon as fed.
“Salda … will function a robust analogue through which we are able to study and interrogate,” Thomas Zurbuchen, NASA affiliate administrator for science, informed Reuters.
A workforce of American and Turkish planetary scientists carried out analysis in 2019 on the shorelines of the lake, generally known as Turkey’s Maldives due to its azure water and white shores.
Scientists imagine that the sediments across the lake eroded from giant mounds which are shaped with the assistance of microbes and are generally known as microbialites.
The workforce behind the Perseverance rover, probably the most superior astrobiology lab ever flown to a different world, desires to seek out out whether or not there are microbialites in Jezero Crater.
They can even evaluate the seaside sediments from Salda with carbonate minerals – shaped from carbon dioxide and water, a key ingredient for all times – detected on the margins of Jezero Crater.
“After we discover one thing at Perseverance we are able to return to have a look at Lake Salda to actually take a look at each processes, () similarities however equally importantly variations which are actually between Perseverance and Lake Salda,” Zurbuchen mentioned.
“So we’re actually glad we have now that lake, simply because I feel it will likely be with us for a very long time”.
Samples of rock drilled from Martian soil are to be saved on the floor for eventual retrieval and supply to Earth by two future robotic missions, as early as 2031.
