The "Express Boy" Tianzhou-3 sets off with a full load. What materials are included in the "Mid-Autumn Space Gift Pack"?

The Mid-Autumn Festival space gift package mainly contains some living supplies, space drinking water, astronaut out-of-vehicle consumables, maintenance spare parts, items needed for experiments, hygiene products, gas supplies, etc. The assembly process will be completed at the space station and the space station to provide the space station with material reserves for subsequent missions.

At 15:10 pm on September 20, 2021, the Tianzhou-3 cargo spacecraft was successfully launched from the Wenchang Space Origin Site in Hainan, powered by the Long March-7 carrier rocket.

Ten minutes later, Tianzhou-3 successfully separated from the launch vehicle and entered the predetermined orbit. The Tianzhou-3 cargo spacecraft carries nearly 6 tons of supply materials. Netizens affectionately call it the "delivery boy" in the spacecraft. It carries a lot of materials, and it coincides with the Mid-Autumn Festival. It seems to be for the astronauts on the spacecraft. It’s the same as sending Mid-Autumn Festival gifts.

The most important material that astronauts need to survive in the space station is air. Tianzhou-3 brought gas bottles to the space station. One gas bottle can be used by astronauts for a long time.

In addition to precious air, it also brought water, the source of life. The water brought to the space station was packed in a water bladder-like package made of a lightweight and soft material. , this ensures that other materials except water are as light as possible, and also ensures that astronauts can drink water safely and conveniently under vacuum conditions, and the packaging after drinking the water is also very easy to store.

In addition to these packages that are as light as possible, there is also a set of expensive and heavy clothes? The extravehicular space suit. An extravehicular spacesuit weighs more than 90 kilograms. It can provide astronauts with breathing oxygen and a suitable temperature outside the vehicle. It can also protect against cosmic radiation. It has very comprehensive functions, so it is also very expensive. The specific price is not known, but It is said that the cost is 8 figures.

The courier Tianzhou-3 in the spacecraft carries a 6-ton "Mid-Autumn Festival gift pack" that can support the needs of the astronauts on Shenzhou 13 for 6 months. Compared with Tianzhou-2 No. 1, it can carry 25% more cargo.

It is worth noting that the cargo carried to the space station has undergone strict quarantine and has undergone nucleic acid testing. Pay attention to epidemic prevention wherever possible.
