UK: British Gypsum’s mine at Brightling near Robertsbridge has provided gypsum samples to researchers from the Natural History Museum. The rock specimens are intended to aid the scientists in looking at signs of past life in preparation for a joint European Space Agency and Russian Roscosmos State Corporation mission to send a robotic rover to mars in July 2020, according to the Rye & Battle Observer newspaper. Previously, NASA's Mars Rover Opportunity found bright veins of a mineral, which appeared to be gypsum, in 2011.
"Minerals like those found at Brightling hide clues within them that can tell us about the history of liquid water where they formed, and they have the potential to trap and preserve organic material. Studying these natural fresh samples on Earth that mimic not just the minerals, but also the formation environments we see on Mars, will give us an insight into the potential for life to be detectable at the ExoMars2020 landing site," said Louisa Preston, UK Space Agency Aurora Research Fellow and member of the Department of Earth Sciences at the Natural History Museum.
