Interplanetary travel is a branch of space exploration that focuses on the transportation of humans and robotic missions between different planets within our solar system. This field involves developing advanced propulsion systems, spacecrafts, and navigation techniques to overcome the vast distances and complexities of space travel. Interplanetary travel has the potential to expand our understanding of the universe, search for extraterrestrial life, and potentially establish human colonies on other planets. Some of the key challenges in interplanetary travel include long-duration space missions, radiation exposure, and the psychological effects of isolation in deep space. Researchers in this field are constantly working on innovative solutions to make interplanetary travel safer, more efficient, and ultimately achievable for future generations.
