(NewsNation) — Strong floodwaters on Mars may have carried a set of boulders to their current location billions of years ago, according to NASA.
The agency’s Perseverance Mars rover photographed the boulders on April 13 and NASA released the composite image earlier this month.
It depicts round boulders that may have been pushed into Jezero Crater during one of three major periods of lake and river development in the ancient past, according to NASA.
The Perseverance rover is in search of signs of ancient microbial life on Mars, among other discoveries, NASA said in a statement.
It’s also working to gather information about the planet’s geology and past climate to pave the way for human exploration.
