This article discusses the hazards that astronauts face in space. One major danger is orbital debris, with thousands of objects floating around in space that can cause damage to spacecraft. The lack of air resistance and gravity also poses a threat, as objects and astronauts will continue to move in the same direction until another force acts upon them. Oxygen levels are critical, as spacesuits provide a finite supply and re-entering spacecraft without proper equalizing of pressures can be fatal. The article also explains what happens to the human body in space, the dangers of low air pressure, and the challenges of returning safely to Earth. Additionally, it mentions the extreme temperatures in space and the risks of overheating. [Extracted from the article] |
