How does the sun shade on this space helmet fit into the helmet?

In summary, the conversation discusses how the sun shade on a helmet fits into the back of the helmet. It may seem confusing at first due to the perspective, but the shade actually slides into a groove or slot and is designed to fit snugly for protection from the sun.

Okay, I realize I'm a bit stupid, but how does the sun shade on this photo fit into the helmet? I mean, it OBVIOUSLY does, but when rotating the shade shape around the knob that deploys it, it doesn't appear to fit in the back of the helmet.
Even though they're curved, it doesn't seem to make sense to me.

Cheers.

It's just an illusion of perspective, trying to project a 3d object in 2d when it isn't oriented perpendicular to you - the front is rotated toward you, making it appear bigger than the back.

Hey there! Don't worry, you're not stupid at all. The sun shade actually fits into the back of the helmet by sliding into a groove or slot. It may seem a bit confusing at first, but once you figure it out, it should be pretty easy to use. The curved shape is designed to fit snugly into the helmet, providing shade and protection from the sun. Hope that helps! Cheers.
 

1. What is a basic space helmet?

A basic space helmet is a protective headgear designed to be worn by astronauts and other individuals who are exposed to the harsh environment of outer space. It is a crucial piece of equipment that provides oxygen, temperature regulation, and protection from radiation and debris.

2. How does a basic space helmet work?

A basic space helmet works by creating a sealed environment around the astronaut's head, allowing them to breathe and maintain a comfortable temperature. It also has a visor that protects the astronaut's eyes from the intense light and radiation of space.

3. What materials are used to make a basic space helmet?

Basic space helmets are typically made from a combination of lightweight, yet strong materials such as polycarbonate, kevlar, and aluminum. These materials are chosen for their ability to withstand extreme conditions and protect the wearer's head.

4. How are basic space helmets tested for safety?

Before being used in space, basic space helmets undergo rigorous testing to ensure their safety and functionality. This includes simulated space environments, impact tests, and pressure tests to ensure they can withstand the harsh conditions of outer space.

5. Are basic space helmets reusable?

Most basic space helmets are designed to be reusable, as they are a crucial and costly piece of equipment. However, they may need to be repaired or replaced if damaged during a space mission or testing.
