Video Exhibits How Onerous It Actually Is to Stroll on Earth After 6 Months in House

Going to area is severe enterprise. How severe? Properly, let this video from NASA astronaut Drew Feustel let you know.

Feustel spent 197 days – so simply over half a yr – on board the Worldwide House Station. That is a reasonably normal mission size. And all that point is spent in microgravity.


However we people aren’t constructed for weightlessly floating round. When our our bodies aren’t consistently straining towards the pull of gravity, all kinds of unusual issues occur. Amongst these, our muscle tissues atrophy, and we lose bone density at about 10 instances the speed of osteoporosis.

Furthermore, when astronauts come again to Earth after a period in area, the return to gravity can induce some fairly extreme vertigo as their sense of steadiness readjusts.

So, transferring round is much more troublesome than once they left. Feustel’s video, posted to Twitter in December final yr, exhibits simply how a lot. He stumbles making an attempt to stroll only a few steps in a heel-toe straight line.

Welcome house #SoyuzMS09 ! On October fifth that is what I seemed like strolling heel-toe eyes closed after 197 days on @Space_Station through the Subject Check experiment…I hope the newly returned crew feels so much higher. Video credit score @IndiraFeustel

The ISS is presently geared up with numerous machines to provide astronauts a full-body exercise. On common, they spend two hours a day utilizing them.


This routine is designed to try to mitigate the atrophy considerably, however even with the train program in place, it takes a minimum of three to 4 years for an astronaut to completely get better after a six-month stint.

That is simply one of many many challenges we’ll want to determine for the inevitable journey to Mars. The longer the keep, the better the bone density loss, and the journey to Mars is a minimum of six months every method.

From March 2015 to March 2016, astronauts Scott Kelly of NASA and Mikhail Korniyenko of Roscosmos spent 342 days in area to conduct observations on the well being results of an extended area mission.

Kelly, as you may guess, was fairly unsteady on his ft too. Astronauts positive are devoted!
