The last space probe sent to mars was InSight a week ago, but we said, it is not a rover, but a lander, that cannot move along the surface.
The last rover sent to Mars was the Curiosity rover in 2011, but NASA has in plan sending the Rover “Mars 2020” in the year 2020. NASA’s new plan is to send along with the car-sized rover a small helicopter, that will fly around scanning the environment and sending the data to the rover and to Earth.
The Mars 2020 mission will have as objective searching for signs of life in ancient times on Mars, when the planet had a magnetosphere, and taking samples of different rocks, which will eventually return to Earth if NASA decides so in a future mission.
The Mars Helicopter must be small and light, so that it can fly on Mars, where the atmosphere is one hundredth of that on the surface of Earth. So the Mars Helicopter will be just 1.8 kg (4 pounds) and its body will be the size of a soft ball.
The Mars 2020 rover and the Mars Helicopter will be launched in July 2020 and will land on Mars in February 2021.
Here is a video from JPL about the Mars Helicopter!
