After a five-year search, NASA has chosen the Jezero Crater for its upcoming Mars 2020 rover mission to look for signs of past life.

Axar.az reports citing Euronews that the North American Space Agency says it will launch the uncrewed robot, about the size of a car, in July 2020 to explore the Red Planet.

Scientists believe Mars was once like Earth. The rover will be tasked with collecting samples, which it will safely keep in a "cache" to later be brought back to Earth for analysis by scientists.

Jezero, located north of Mars' equator, has land formations stretching back 3.6 billion years and was chosen from more than 60 locations because of its rich terrain and because its lake-delta system contains at least five different kinds of rock, including clay and carbonates that may reveal evidence to show signs of past, microbial life.

"Getting samples from this unique area will revolutionise how we think about Mars and its ability to harbour life, said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate, in a statement.
