ask
Compared with Tianzhou-2, what is the difference between the cargo carried by Tianzhou-3?
answer
In terms of types, the astronauts' living materials carried by Tianzhou-3 are the same as those carried by Tianzhou-2 and before, mainly including space food, water, clothing, and crew equipment. However, depending on the task planning, there are differences in quantity. The Shenzhou 13 crew had to stay in the sky for six months, and the food, water, and daily necessities carried by The Tianzhou 3 were 3 times that of the Tianzhou 2, and the astronauts' daily necessities carried were more than 3 tons.
In addition, Tianzhou-3 also prepared Spring Festival supplies for astronauts.
Among the supplies, there are women's clothing, hygiene products, etc., including cosmetics, which are specially prepared for female astronauts.
What emergency supplies did Tianzhou 3 deliver to the Shenzhou 13 crew?
The emergency items delivered by the Tianzhou-3 cargo spacecraft to the space station mainly include two categories:
(1) Tianzhou-3 replenished hundreds of kilograms of emergency water;
(2) In the case of an emergency in the cabin, such as being broken down and losing pressure, negative pressure gas is needed, and Tianzhou-2 has been fully loaded. However, Tianzhou-3 also brought negative pressure gas, mainly for the purpose of increasing the sealing space after the launch of the experimental module next year, and the demand for gas increased, so the negative pressure gas was transported up in advance.
More than 200 bags, how to distinguish?
By soliciting the opinions of the Shenzhou XII astronauts, Tianzhou-3 identified the cargo bags of various materials through colorful butterfly belts.
For example, the green logo for food represents green food; the equipment of the space station is marked in dark blue; the astronaut material is marked in light blue... In this way, the astronauts know at a glance from a distance where the goods they are looking for are.
