Why Astronauts Wear Orange and White

The bright orange color astronauts wear to go out for launch is called International Orange, and it’s the same shade as the paint that coats Tokyo Tower in Japan, and the Golden Gate Bridge in San Francisco. However, once astronauts are in space, they swap orange for snow-white wear. So what gives with the different colors?

Well, there are actually two main types of spacesuits. The first one is the Advanced Crew Escape Suit, aka the "orange suit," aka the "pumpkin suit." Astronauts wear this full-pressure suit during "lift-off". These spacesuits are crucial for those who are heading for super high altitudes. But still, why this color? And what about the white, bulky spacesuits? What's their purpose?

SUMMARY:
- The orange suit is equipped with different stuff that can help an astronaut to survive if something goes wrong during the launch or landing of the spaceship.
- Astronauts wear EVA suits when they go on a spacewalk! Such an outfit can protect them from the unfriendly conditions of outer space, what with its extreme temperatures and near-vacuum!
- In case the tether tears, the EVA suit has a backup system. This system includes small jet thrusters which can be controlled from the station with the help of a joystick.
- Months after coming back from long missions in space, astronauts still tend to let go of things while they’re still in mid-air.
- There was an astronaut who’d been waiting for a whopping 19 years before he finally flew to space.
- All American astronauts have to learn Russian to be able to run the International Space Station using Russian-language manuals, if there’s no alternative.
- During space adaptation, 50% to 75% of astronauts have highly unpleasant syndromes, such as vertigo, headaches, nausea, and overall tiredness.
- When astronauts are in space, they often see random flashes of light - and it's not hallucinations!
- Before going to space, astronauts have underwater training, which is supposed to simulate zero gravity.
- According to NASA, they accept only 8 applicants out of 6,000! On top of that, the selection process takes around 18 months!
- If an astronaut cries in space, tears don't flow down their face. Instead, they gather into thick blobs of liquid around their eyes because the water surface tension holds tears together.
- Astronauts who forget to attach themselves to something when they sleep can easily float away and bump into a hard surface.
- Astronauts see a sunrise and a sunset every 45 minutes, which totals 15-16 sunsets and sunrises each day.
