Recently, NASA released a video which features Drew Feustel an American Astronaut. The video was shared by the astronaut on Twitter whose caption was “Welcome home #SoyuzMS09! On October 5th this is what I looked like walking heel-toe eyes closed after 197 days on @Space_Station during the Field Test experiment…I hope the newly returned crew feels a lot better”.
Confusing, isn’t it? How can an astronaut who has been earthling for many years now facing difficulties in walking on Earth? It’s been a week since the new crew members returned safely to Earth. Many astronauts and cosmonauts who live in space for more than six months tend to experience some physical changes which have noticeable effects when they return to the Earth’s gravity.
They feel many changes in blood pressure, coordination, balance, vision, and ability to walk, which puts a major impact on their ability to perform certain tasks. Current crew members landed on Earth with quick rehabilitation facilities and proper medical assistance, but the future crews who are traveling to Mars or other destinations don’t have such resources or time to recover from these changes. The investigation of Field Test includes many studies which are designed by scientists from Russia and NASA to aptly investigate the severity, complexity, and duration of such changes.
Above all, the astronauts use many equipment and tools to do their job to remain safe. Spacewalks are the most important thing for the astronaut, and it usually lasts for five and eight hours which depend as per the job. The NBL (Neutral Buoyancy Laboratory) helps the astronauts to practice spacewalks in a swimming pool. The astronauts then spend seven hours inside the pool for spacewalk training. The ISS crew experiences the gravity which helps them to float in the space. And no one knows what affects their human body when they land on the red planet, Earth.
