The "Doctor Crew" has started work! Netizen: Why don't these glasses float?

Shenzhou 16 "Doctor Crew"

Within about two weeks of entering the space station

Quickly organize materials

Load out of cabin and other large-scale work

Three astronauts in orbit

Extravehicular work of space radiation biology device

Get into work mode quickly!

my country's first

Extravehicular Radiation Biological Exposure Experiment

Shenzhou 16

Since arriving at the space station on May 30, 2023

A lot of work has been done

This includes conducting

Extravehicular work of the space radiation biological exposure experiment device

Astronauts will carry

Mounting to load transfer mechanism

Afterwards

Close the cargo airlock hatch of the Mengtian experimental cabin

Through this device

Conduct space particle radiation and other environmental factors

Study on biological effects of sample materials

Providing life support for biological samples in scientific experiments

During the test load out of the cabin

Cargo airlock hatch opened

Grasp the test load through the robot arm

Install outside the cabin

This is the first time that my country has carried out

Extravehicular Radiation Biological Exposure Experiment

Research on radiation biology and space science

A milestone in significance

In the future, the device will be used for

Radiation damage and genetic mutation of organisms

Preparation of radiation protection drugs

and provide services for biological assessment of radiation risks

Astronauts wear glasses in space

In addition to marveling at these "high-end" space experiments

And exquisite aerospace technology

Many netizens are also curious

Astronaut Gui Haichao in space

Why don't the glasses I wear float up?

In fact, for astronauts

Solving this problem is simple

Tie an elastic band behind the temples to help secure them

Or design the glasses to look like diving goggles.

In addition, there is a little-known fact

Astronauts actually work in space

Need to wear glasses

Theoretically, the human eye

Even the whole body

Can't face it directly

Vacuum, low temperature, microgravity, strong radiation environment

In addition to manned spacecraft, once entering space

Astronauts also need

A small manned spacecraft - an extravehicular suit

△Shenzhou 15 astronauts exit the cabin

The most eye-catching part of the extravehicular suit

It's a big black helmet

Mainly serves the eyes of astronauts
