The Perseverance rover will be collecting geologic samples from the Jezero crater for 30 Mars days. Scientists believe the crater formerly held a lake in ancient times, when there was liquid water on the planet surface.The samples will be placed in the cleanest sample containers ever created on earth, and left on the planet's surface. The next Mars mission in 2026 to 2028 will be spear-headed by the European Space Agency to retrieve the samples. The mission will use the rover to collect the samples and place them in a rocket which will blast off from the planet's surface and return to earth. With the technological advances being made in robotics engineering, the entire mission is expected to be conducted Robotically, without any human astronauts. The samples will be analysed by renowned scientists from all around the world. However, it will be quite a few years yet before we know whether life ever existed on Mars.
