Mars Exploration Rover

Mars exploration rovers are robots which have been sent by scientists to explore Mars. These rovers have cameras, scientific instruments, and other technology which helps scientists learn more about the Red Planet. They use robotic arms and wheels to travel around, and can even dig and take samples of soil. Scientists use these rovers to collect data which will help them learn more about the surface of Mars, what kinds of rocks and minerals are there, and even if there is water on the planet. The data collected by rovers can help scientists figure out if Mars could ever support life.
