Robotic spacecraft are vehicles designed to explore space without human presence. They are equipped with various instruments to collect data, take images, and perform experiments. Notable examples include the Mars Rovers and the Voyager probes, which have provided invaluable information about our solar system. These spacecraft can operate autonomously or be remotely controlled from Earth. They play a crucial role in missions to planets, moons, and asteroids, helping scientists understand the universe better. Their ability to withstand harsh conditions makes them essential for deep space exploration.
