Human Spaceflight: Technological Advances, Health Implications, and the Path to Interplanetary Travel

Human spaceflight has advanced from brief orbital missions to sustained international cooperation on the International Space Station (ISS). As humanity looks toward more ambitious goals, such as lunar bases and Mars exploration, understanding the challenges and opportunities of human space travel is critical. This paper provides a comprehensive analysis of the current state of human spaceflight, focusing on technological advancements, health and safety concerns, and future mission planning. It reviews the physical, psychological, and environmental factors affecting astronauts, technological innovations supporting deep-space missions, and emerging ethical and logistical considerations. This research concludes with an evaluation of potential pathways for human settlement on Mars, the Moon, and beyond.
