The Actual Science Behind Astronauts Wearing Orange & White Spacesuits

[4Vikram]

We often see astronauts taking off in their orange spacesuits in space shuttles and never think about why only bright orange? Why not bright neon or blue for that matter? For a community which is smarter than us in every sense, there has to be a reason as to why bright orange is their preferred choice.

The reason or should we say the science behind this is really simple. NASA isn’t trying to make a fashion statement, and like every other component of the astronaut’s suit and the spacecraft, there is a rational explanation for the colour of their suit too.

The bright orange or International Orange, as it is called in space lingo, is one of the most visible colours which are important for search and rescue. It is really important during a search rescue to identify the astronaut as early as possible because every minute makes a difference between life and death.

The suit, as of now, consists of a pressurized shell which saves them from an accident which might occur during a botched landing or takeoff. One of the astronauts in Kalpana Chawla’s flight had a shell suit which was broken during entry and made him the first victim of the explosion when the aircraft entered earth’s atmosphere. ACES or Advanced Crew Escape Suit also contains a steady supply of water and air along with parachutes.

The other kind of suit of an astronaut’s wardrobe is the one used for spacewalks and Extravehicular activities (EVAs). These white suits are designed for an astronaut’s survival in space rather than on earth. The black vacuum of space requires a pure white suit which is easily visible to trace an astronaut. Also, the white suit reflects the excessive heat of the sun.

These EVA suits are heavier than the ACES and are equipped with temperature control mechanism, breathable air and clean water. Russia has its own indigenously developed space suits called the Orlan suits. China also uses the same design as followed by Russia to prepare their Feitian spacewalk suits

Did u know the captain of the space craft has to play the game "black jack " with the director of the launch program. Untill the captain beats the director they werent allowed to go near the space craft. Weird ha?

really? but what is that support to do with this? is just a casual game to start or does it relate something serious?

just some belief they following since the beginning.

and did u know the spacewalk suit weighs 300 lbs with the tools and the kit they carry on their back and there is 90% gravity in the space, at least at ISS.the free falling theory comes into action when you see an astronaut floating in the ISS.
