如何在太空中洗头

如何在失重的太空中洗头发?针对这个长期困扰宇航员的问题,国际太空站飞行工程师凯伦.尼伯格于2013年进行了示范。在太空洗头的关键用具包括挤压式水包,免冲水干洗香波,毛巾和梳子。虽然如此,但是这部主题影片展示了整个洗头过程只需要 寥寥数分钟。残留的水会最终从头发处蒸发,被太空站的空调系统收集,然后过滤为纯净水。尼伯格在太空生活180天后返回地球,并且在美国太空总署历任了数个职位,其中包括机器人部门主管的职位。

How to Wash Your Hair in Space 
Video Credit: NASAExpedition 36 Crew

Explanation: How can you wash your hair in space — without gravity? Long a bother for space-faring astronauts, Karen Nyberg, a flight engineer on the International Space Station (ISS) in 2013, gave a tutorial. Key components are a squirt package of water, no-rinse shampoo, and vigorous use of a towel and comb. Even so, thefeatured video shows that the whole process should take only a few minutes. Residual water will eventually evaporate from your hair, be captured by the space station’s air conditioning system, and be purified into drinking water. After returning from a total of 180 days in space, Nyberg has worked for NASA in several capacities including as the Chief of Robotics branch.
