Manned missions involve human astronauts traveling to space to conduct research, exploration, or other activities. These missions allow for real-time decision-making and adaptability, as astronauts can respond to unexpected challenges. Notable examples include the Apollo program, which landed humans on the Moon, and the International Space Station (ISS), where astronauts live and work for extended periods. Unmanned missions, on the other hand, utilize robotic spacecraft to explore space without human presence. These missions can cover vast distances and operate in environments too harsh for humans. Examples include the Mars rovers, which gather data about the Martian surface, and the Voyager spacecraft, which have traveled beyond our solar system.
