Astronaut Suit Design.

 Hello all, welcome to another lockdown post.

Today is about an ASTRONOMICAL topic, the design of astronaut suits.

Now, let's get into it.

Essentially, the suit, called the Extravehicular Mobility Unit (or EMU for short), is comprised of an outer and inner layer. 

The inner layer is made of a soft fabric which has tubes weaved through which feed water straight to the astronauts. This is necessary to maintain body temperature as the astronauts work.

The outer layer is comprised of two parts, the leggings and the upper body bit. The upper body unit is a rigid piece, while the leggings remain the same.

That then brings us to the helmet:

The helmet is made up of several (confidential) materials. The yellowish tinted glass is the visor, which helps when dealing with the sun. If more cover is needed, there is an added sunshield that flicks down exactly like the visor.

Now, there's a few reasons why the space suit is needed:

1. The astronauts need oxygen in space, since there's literally nothing in space.

2. They need it to withstand the everchanging temperature in space.

3. They need it to protect themselves from radiation.

The equipment needed for a spacewalk also has to be tethered to the suit itself, so they don't go flying off to kingdom canal.

Safety measures for the astronauts include:

• Various check overs for life support systems and such.
• Communications check.
• Fitting so there is a little bit of pain for extra security.
• Using safety tethers.

Anyway, that's me.

Stay safe boys.
