The Mars 2020 rover, which sets off for the Red Planet this year, will not only search for traces

The Mars 2020 rover, which sets off for the Red Planet this year, will not only search for traces of ancient life, but pave the way for future human missions, NASA scientists said on Friday as they introduced the vehicle.
The rover has been constructed in a large, sterile room at the Jet Propulsion Laboratory in Pasadena, near Los Angeles, where its driving equipment was given its first successful test last week.
Shown to invited journalists on Friday, it is scheduled to leave Earth in July 2020 from Florida’s Cape Canaveral, becoming the fifth US rover to land on Mars seven months later in February.
“It's designed to seek the signs of life, so we’re carrying a number of different instruments that will help us understand the geological and chemical context on the surface of Mars, "deputy mission leader Matt Wallace told AFP.
Among the devices on board the rover are 23 cameras, two "ears" that will allow it to listen to Martian winds, and lasers used for chemical analysis.
Approximately the size of a car, the rover is equipped with six wheels like the former US rover, Curiosity, allowing it to travel along rocky land.
Speed is not a priority for the vehicle, which only has to cover around 200 yards (180 metres) per Martian day ---approximately the same as a day on Earth.
Fuelled by a tiny nuclear reactor, Mars 2020 has seven-foot-long (2 metres) articulated arms and a drill to crack open rock samples in locations scientists identify as potentially suitable for life.
“We are hoping to move fairly quickly. We'd like to see the next mission launched in 2026 which will get to Mars and pick up the samples, put them into a rocket and finally bring them back to the Earth,” said Wallace.
NASA’s Mars 2020 will remain active for at least one Martian year, which is around two years on Earth.
