Astronauts struggle to place one foot in front of the other in 197 days in space – Technology News, Firstpost



It is weightless in weightlessness and I feel good fun.

However, the low gravity six months of the space station can harm anyone.

Most recently, NASA astronauts AJ (Drew) Feustel and Ricky Arnold, and Russian astronaut Oleg Artemyev landed on Earth after spending 1971 on the International Space Station. The crew returned safely after three spacewalks (which were to investigate air leaks at the ISS) and hundreds of research experiments at low gravity, trying to perfect the orbiting laboratory.

But their return to Earth, especially in the case of Feustal, had some unpleasant side effects.

His wife caught a video about his recovery and shared it on Twitter.

This video is surfing on the internet. Austin was embarrassed at how difficult it was to do something "simple" just like walking around the globe everywhere. Drew did all his life without sweating.

Prepare for a spacewalk: field tests

There are quite a few astronauts who spend between six months and twelve months in space experience after they return. Unexpected changes in vision, balance and coordination, blood pressure, and walking ability are something that astronauts can train. Nevertheless, the impact on the ability to perform basic tasks can be affected when you return regardless.

As astronauts return, priority is medical support, health screening and rehabilitation. The space agency that future astronauts aim to set up a manned spacecraft on the moon and Mars is important to monitor and understand how these changes can be easily restored by current and future astronauts.

Designed by NASA and Roscosmos to study the complexity, severity, and duration of astronaut change, initiate "field testing" to improve recovery time and prevent injuries in future missions.

One of those components in the field test is warming up for the "Neutral Buoyancy Laboratory" to float in space. This lab is a huge pool of about 23.47 million liters of water to simulate a floating feeling in space.

The average spacewalk is between 8 and 8 hours in real time, while the astronauts are training in the buoyancy lab for seven hours per hour spent on spacewalks. Full-time preparation time is between 35 and 56 hours!

Another exercise for spacewalk is virtual reality. Using virtual reality images of what they can see during a spacewalk will be visible to astronauts as they move. Using a special glove with a sensor, you can see a VR simulation of how you feel when you want to capture motion and capture a motion in real space.

Feustal was a pro astronaut and recorded a total of 226 days of space flight during three expeditions. He occupied second place among all NASA astronauts and spent 61 hours and 48 minutes in nine spacewalks working as astronauts.

Obviously, gravity can even confuse us.
