Astronauts do not just climb into a spacecraft and zip off into space, they need months of study and training first. They have to be in peak physical condition and some astronauts claim their training is much harder than any missions. Astronauts train for all sorts of situations. When necessary, they use real aircraft equipment simulations, virtual reality systems, and computer simulations. Astronauts' training is long training, have a year of basic training, plus advanced training for missions.
Underwater training:- Floating in water is very like floating in space, so astronauts use special water tanks to train for spacewalks. One NASA tank can hold a full-size replica of the space shuttle's payload bay.
Around and around:- A multi-axis trainer helps astronauts yet used to the out-of-control spinning feeling they will get from tumbling in weightless conditions.
Weightless wonder:- Flown in a special way an airplane with no seats and padded walls helps astronauts get used to feeling weightlessness. This plane is known as the vomit comet because its motion makes people feel sick.
Walking on the Moon:- At the NASA Lunar Landing Research Facility of Hampton, Virginia, USA, moonwalking practice involves suspending the astronauts by heavy clothes.
The American Space Agency NASA awards astronauts' wings to service personnel and civilians who have flown more than 80 km above the Earth's surface.
Astronauts pack lots of things when they go into space from Earth and they wear different clothes depending on what they are doing in space. During launch and re-entry astronauts wear a special bright orange suit called a pumpkin suit and the tools are stored in huge packets on the legs of their suits.
For spacewalk astronauts need to wear an extravehicular mobility unit (EMU). Underneath this astronauts wear space underwear, a one-piece suit with small water-carrying tubes that help keep them cool. An EMU can support an astronaut working in space for about 8½ hours. For astronauts under the helmet, there is a communications cap called a snoopy cap that has a headphone and a microphone.
Launch and Entry Suit
The suit has a built-in life jacket.
A parachute is strapped to the back of the suit.
The equipment's an astronaut's suits are
Motion sickness tablets
Knife / Cutter
Day / Night flare and smoke signal
Astronauts carry safety equipment in case of emergency. They are
Life raft:- This is used in the crew having to crash land at sea.
Sea dye:- This is used to color water after an emergency landing to alert rescuers.
Drink: - Astronauts are mandatory to sip fluid regularly to avoid dehydration.
Chemical light:- Astronauts definitely carry some lightsticks along with them and these lightsticks keep them in the pocket of their suits.
Do you know that in space astronauts wear clothes the same type of clothes, would wear on Earth-like shorts, a T-Shirt? Their clothes don't change in space, they will change after they were returned to Earth only because there are no washing machines onboard the space station.
Extravehicular mobility units or EMUs are a bit like miniature spaceships with all the things astronauts need to survive. Astronauts use EMU for working outside the space shuttle and on the International Space Station.
An astronaut needs to work outside to repair satellites or check the outside of the spacecraft.
A bed on the wall baby wipes for a wash, footholds, and edible toothpaste! But you have to know that life on a space station is entirely different from life on Earth but astronauts need to do everything that you do in everyday life on Earth for example as they eat, exercise, sleep, work and play but they have to do all these things in a home without gravity. It's not easy to sort our bulky spacesuits in zero gravity.
When astronauts arrive at a space station they bring supplies with them. Imagine trying to unpack your suitcase when you are floating. Astronauts' muscles don't work very hard in zero gravity so they quickly lose strength, so astronauts exercise for about two hours a day.
Experienced scientists regularly join the astronauts in the space station to carry out a variety of experiments and record the results.
Food is supplied in sealed packets and some of it is dehydrated because the water has to be added before the food can be eaten.
Most of the crew use sleeping bags, which have to be strapped to the walls of the space station. The bag holds the astronaut's arms in place. Otherwise, they would float above their head
Astronauts use combs, toothbrushes, and toothpaste. But the toothpaste doesn't froth and gets swallowed. Wet wipes are useful for a speedy wash. Hair washing is possible but rare!.
We have all seen workers on a construction site hammering and drilling. Imagine a construction site floating in space high above the Earth's surface. That's what astronauts have to cope with when they are repairing a satellite or putting together a space station.
In orbit, the strong sunshine heats astronauts up. Surprisingly, it's difficult to lose heat in space, so spacesuits have to include or refrigeration unit!
An astronaut may be outside the space station for hours at a time. Between 1998 and 2008 more than 60 spacewalks were performed. Each time two astronauts worked on International Space Station.
A piece of history
The first-ever spacewalk was performed by Soviet astronaut Alexei Leonov on 18th March 1965. Alexei Leonov in the Soviet Union and around the world. Edward White was the first American who do a spacewalk.
Astronauts have to work slower than construction workers on Earth. If they twist a bolt too quickly, they will send themselves into a spin.
Space tools are extra-large so that astronauts can grab them in their bulky gloves. They also have to be tied to astronauts to prevent them from floating away.
Do you know?
Some astronauts suffer temporary hearing problems after living on a space station. Why? Because the necessary air filters, fans, and pumps make it very noisy.
EVA - Extravehicular Activity. It means Space Walking
