宇航服是保障宇航员的生命活动和工作能力的个人密闭装备,可防护空间的真空、高低温、太阳辐射和微流星等环境因素对人体的危害。它有两种颜色,一种是橙色,另一种是白色。我们常见的是穿着白色宇航服在宇宙“遨游”的宇航员,那穿着橙色宇航服和白色宇航服有什么区别呢?

Let's chat about Space Fashion, shall we?

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 evening wear.

(It's always evening in space.) 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." Trick or treat!

Astronauts wear this full-pressure suit during "lift-off".

These spacesuits are crucial for those who are heading for super high altitudes.

There, the pressure is so low that people can't survive without a special protective suit...

Anyway, 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.
