The strongest space dispatcher Tianzhou-3 successfully launched-Industry Finance-Wangbao

The Continental Long March 7 Yaosi carrier rocket was launched at 15:00 on the 20th at the Wenchang Space Launch Site in Hainan and successfully sent the Tianzhou-3 cargo spacecraft into the scheduled orbit. This is the 20th launch mission of the mainland manned space project. The 389th flight of the Long March series of carrier rockets.

According to the China Manned Space Engineering Office, at 15:10 on the 20th, the Long March 7 Yaosi carrier rocket carrying the Tianzhou-3 cargo spacecraft was launched. About 597 seconds later, the spacecraft successfully separated from the rocket and entered the scheduled orbit.

According to comprehensive land media reports, the Tianzhou-3 cargo spacecraft will perform the fifth flight mission of the continental space station’s key technology verification and construction phase. According to the mission plan, Tianzhou-3 is loaded with astronauts’ living supplies, extravehicular space suits (space suits), exit consumables, space station materials, and some payloads and propellants. “Cargo spacecraft” is hailed as “the strongest space delivery man.”

Feng Yong, commander-in-chief of Tianzhou-3 of the Fifth Academy of the Continental Aerospace Science and Technology Group, said that the cargo carried by Tianzhou-3 this time is “three expensive”. Atmospheric environment, the “cylinders” brought to astronauts this time are made of special composite materials and can be filled up to 300 times the atmospheric pressure. One cylinder of oxygen can be used by astronauts for a long time.

The second is precious water resources. This time, Tianzhou 3 carried multiple sets of water tanks for astronauts to drink and use. These water tanks are all packaged in “water bladder” made of light and soft materials, which not only guarantees the safety of drinking water. , And better storage. This time the astronaut’s residence time has nearly doubled, so Tianzhou-3 carries more water than Tianzhou-2.

The third is the most “golden and precious” spacesuit. Its main function is to provide astronauts with oxygen, temperature adjustment, radiation protection, etc. needed for survival in space. A set of equipment weighs more than 90 kilograms, and the price is said to exceed 8 digits. The renminbi can be said to be “the most expensive clothes on earth.”

Prior to this, the mainland Shenzhou 12 manned spacecraft successfully landed on the 17th and safely brought back to Earth the three astronauts Nie Haisheng, Liu Boming and Tang Hongbo who had completed a three-month residency mission at the space station. The launch of Tianzhou-3 is considered to prepare for the next tier of space station missions.
