When Shenzhou seven returned to the ground from behind the clouds, the first step for the 3 astronauts to set foot on the land will be the return of the astronauts wearing the "Qingdao R & D" astronauts.

A few days ago, technicians from the technology research and development center of the double star group disclosed to reporters the important data of "God seven astronauts returning special shoes": the weight of these shoes is only about a kilogram, after pressing, the thickness is three fingers high, which can adapt to all kinds of harsh environments, while the price is in tens of thousands of yuan, and the country only produces more than 20 pairs.

What are the shoes worn by astronauts back to the ground?

In the field of Aerospace Science, these shoes have a professional name called "astronaut's return shoes".

Reporters learned that, as early as 2004, the Beijing Aerospace Medical Research Institute began to organize research and development for the needs of the development of space industry.

After surveying the well-known shoemaking enterprises both at home and abroad, Qingdao's Twin Star (000599, stock bar) has been selected.

In China, there is no precedent for producing "astronaut's return shoes".

How should it be made?

Double star technicians have conducted numerous public relations studies.

"To build up a database of human biomechanics for statistical data, our technicians have measured tens of thousands of feet."

The technicians of the technological research and development center of the double star group, who bear the task of scientific research, told reporters.

Before the launch of Shenzhou VI in 2005, the double star group developed the first pair of "astronaut's return shoes", along with Fei Junlong and Nie Haisheng roaming the outer space.

But when they were out of the cabin, they did not really wear the astronauts' feet.

"That's also a test process," explains the technician.

Before the launch of Shenzhou seven, the space group once again invited the astronauts to return their shoes.

After nearly a year and a half of hard negotiations, the double star group has undertaken the R & D work of "astronaut's return shoes" again.

This time, when the three returned astronauts out of the re-entry module, they will really wear the "astronaut return shoes" developed by the two stars.

How much is the weight of a shoe?
