Interplanetary travel refers to the journey between different planets within our solar system. This exciting concept involves spacecraft designed to transport humans or robots to explore planets like Mars or Venus. Scientists and engineers work hard to create technology that can withstand the harsh conditions of space, such as extreme temperatures and radiation. To make interplanetary travel possible, we need powerful rockets and advanced navigation systems. Missions like NASA's Perseverance Rover have already begun exploring other planets, gathering valuable data. As we learn more about our neighboring worlds, the dream of sending humans to places like Mars becomes more achievable, opening up new possibilities for exploration.
