Space explorers are individuals or teams who travel beyond Earth to study outer space. They use advanced technology, such as spacecraft and telescopes, to gather information about planets, stars, and other celestial bodies. Their missions can include sending robotic probes to distant planets or conducting experiments on the International Space Station (ISS). These explorers often work for organizations like NASA or ESA and contribute to our understanding of the universe. Their discoveries can lead to new knowledge about the origins of the solar system, the potential for life on other planets, and the effects of space travel on the human body.
