On February 15, 2008, Rex Waldheim and Stanley Love completed the final extravehicular activity (EVA) of their STS-122 mission. The two astronauts spent nearly seven hours working outside the International Space Station (ISS), attaching the Columbus laboratory to the ISS.
This was no easy task, as they had to maneuver the large piece of hardware into place while contending with the weightlessness of space. However, they were successful in completing their mission, and the Columbus laboratory has since played an important role in the research conducted on the ISS. Thanks to the hard work of Waldheim and Love, astronauts have been able to conduct a variety of experiments in microgravity, furthering our understanding of the universe.
In space, there is no up or down. There is only the spacecraft and everything else in it. That means that the floor astronauts walk on is really the ceiling, and the roof of the spacecraft is their floor. It can be a confusing concept for people who are used to living on Earth with its familiar gravitational pull.
But there is one thing that astronauts do need in space: shoes.
Shoes are not necessary in weightlessness, but crew members enjoy the comfort and warmth of soft footwear. Many astronauts simply wear socks as they float around inside the spacecraft.
There are several reasons why shoes are still important for astronauts. First, shoes protect the feet from sharp objects and other hazards inside the spacecraft. Second, shoes help keep astronauts’ feet warm. In space, the temperature can range from -250 degrees Fahrenheit to +250 degrees Fahrenheit, and human beings are not used to such extreme temperatures. Third, shoes provide traction on surfaces that might otherwise be slippery.
Fourth, shoes help astronauts keep their footing during takeoff and landing. On Earth, the force of gravity keeps us firmly planted on the ground. In space, there is no gravity, so astronauts have to be careful not to float away during takeoff or landing.
Fifth, shoes help absorb the shock of walking on uneven surfaces. On Earth, our shoes protect our feet from the impact of walking on concrete or asphalt. In space, there might be obstacles in the way, so astronauts need shoes that can absorb the shock of walking on them.
Astronauts have worn many different types of shoes during their time in space. Early astronauts wore simple sneakers or boots. Today, astronauts wear special space boots that are designed to protect their feet and provide traction on slippery surfaces.
So next time you see an astronaut floating around in space, remember that their shoes are not just for show. They are an important part of their space suit and help keep them safe during their journey into the great unknown.
Astronauts’ suits are made of special materials that protect them from the harsh environment of space. They are also insulated to keep astronauts warm in the extreme temperatures of space. Most importantly, astronauts’ suits are equipped with a pressure system that maintains a constant pressure inside the suit, even when the astronaut is outside the spacecraft.
The shoes worn by astronauts are also made of special materials. They are often insulated to keep the astronaut’s feet warm, and they have a special grip to help the astronaut stay steady in the weightlessness of space. Some shoes even have magnets in them to help keep astronauts’ feet firmly planted on the floor of the spacecraft!
Failures of Current and Former Astronauts
Although astronauts are trained extensively for their missions, they are not immune to failure. In fact, some astronauts have failed in spectacular ways.
One of the most famous failures was that of Lisa Nowak. In 2007, she attempted to kidnap a rival astronaut, claiming she was “wearing a diaper, so she wouldn’t have to stop on the drive from Houston to Orlando.” She was arrested and later dismissed from the astronaut program.
Other astronauts have been involved in less serious incidents. In 2015, Scott Kelly admitted to accidentally leaving a $100,000 camera on the International Space Station. And in 2018, an astronaut had to be rescued after getting stranded in space when his tether broke.
Despite these failures, astronauts are still some of the most highly trained and respected people in the world. They undertake risky missions in order to further our understanding of the universe, and they serve as an inspiration to us all.
