Meet the Mars 2020 Rover. It is a robotic scientist. NASA will send it to Mars in 2020. Its job is to look for clues about life on the Red Planet.
The rover has one arm. That arm is seven feet long. Tools are attached to it. They are used to study rocks and soil on Mars.
One of the rover’s tools is a drill. It scrapes and cuts into rocks. It does this to collect samples. Then the rover places the samples inside of tubes.
Could humans live on Mars? The rover will help us find out. NASA hopes to send astronauts to Mars within the next 20 years.
