宇航员在长期空间飞行任务中面临严重的健康风险,促使美国航天局为今后的火星飞行任务研究这些影响。 Astronauts face severe health risks on long space missions, prompting NASA to study these effects for future Mars missions.

长期空间飞行任务的宇航员面临严重的健康挑战,包括肌肉萎缩、骨骼损失、视力问题以及长期孤立造成的心理压力。 Astronauts on long space missions face severe health challenges including muscle atrophy, bone loss, vision problems, and psychological stress from extended isolation. 这些风险因辐射照射和微重力而加剧,它们可能导致癌症、心血管问题和免疫系统衰弱。 These risks are heightened by radiation exposure and microgravity, which can cause cancer, cardiovascular issues, and weakened immune systems. 美国航天局正在研究这些影响,以便为今后火星探索等深空飞行任务做准备。 NASA is studying these effects to prepare for future deep-space missions like Mars exploration.
