[EN VIDÉO] Time lapse of Thomas Pesquet’s spacewalk outside the vehicle On June 16, 2021, Thomas Pesquet and Shane Kimbrough performed a spacewalk…
Man was born to live on earth. Not in space. So when he ventures there, sometimes not very pleasant things happen. Muscles that atrophy. A blurry vision. Problems urinating. Or even erectile dysfunction.
Nails fall in space
Spacewalks – Extravehicular Walks (EVA), as astronauts call them – seem to have a very strange consequence. Onycholysis, you see, the peeling… of nails! The cause of the problem appears to be the astronauts’ gloved hands. Because the gloves they use for their EVA tend to limit the mobility of the joints that connect the palm to the fingers. Result: increased pressure on the fingers, leading to reduced blood flow, tissue damage and…nail loss.
Researchers note that most of these injuries occur on the middle finger. And most common among female astronauts. Which suggests that poor glove fit could be playing a role… although NASA has a habit of making bespoke materials!
