Tianzhou cargo spacecraftThe Tianzhou series cargo spacecraft was powered by the Long March series of rockets and was an important part of China's manned space project. It was mainly responsible for transporting supplies and loads for the manned space station or manned space laboratory, replenishing propellants, on-orbit storage, and descending waste materials. After the end of the mission, it would be controlled by the ground to fall in a predetermined area or bring the space station waste back to the atmosphere to be burned.
For example, Tianzhou-3 was loaded with astronauts 'living supplies, extraterrestrial spacesuits and extraterrestrial consumables, space station platform materials, part of the load and propellants, etc. Tianzhou-6's cargo loading capacity exceeded 7 tons for the first time, making it the world's largest cargo transport capacity as of January 2024. Tianzhou VII delivered a large amount of supplies and equipment to the space station during its orbit. After completing its mission, it successfully evacuated from the space station assembly and entered the independent flight phase. Later, it would choose a controlled re-entry into the atmosphere in the near future. Most of the spacecraft's components would be destroyed during re-entry, and a small amount of debris would fall into the designated safe waters of the South Pacific. Moreover, Tianzhou VII was also responsible for verifying and perfecting China's space station technology (including key technical links such as docking, docking, and evacuation). Its controlled re-entry into the atmosphere was also a test of China's space debris management capabilities.

Mercury"Mercury" has many meanings. From a celestial point of view, Mercury was a planet in the solar system. It was the closest to the sun and was mentioned in the children's song about the solar system, Planet Song. In terms of music, there was the song " Mercury," sung by American male singer Sufzhan Steven, and Mercury Music, which was founded in 1945 in Chicago. Mercury Music developed rapidly in the classical music market, and its sound engineer used three-microphone sound to achieve good results. In the field of network equipment, Mercury was a supplier of network communication equipment. Its products covered the fields of ether network, wireless local area network, and so on. There were many ways to set up the Mercury Routers. For example, you could first connect the power supply, connect the network cable, connect the phone to the default wireless network signal, automatically jump to the settings page, and set up according to the detected Internet access. You could also connect the default wireless Wi-Fi signal of the Routers and enter melogin.com in the browser to set up. In addition, Queen's Freddy Mercury was also a reference to Mercury.

Mercury"Mercury" had many meanings:
- In the field of astronomy, Mercury was one of the eight planets in the solar system and was the closest to the sun. It had a mass of 3.3× 1023 kg and a density of 5.43 g/cm. It was second only to Earth and was the second densest celestial body in the solar system. It has an average diameter of 4,880 kilometers and no natural satellites. It probably had a solid outer shell and mantle, covering a solid outer core, a liquid core, and a solid inner core. The iron core accounted for about 57% of the total volume. There was a dipolar magnetic field, which was about 1.1% of the Earth's strength, and an equator magnetic field with a strength of about 300 nT. The atmosphere-exosphere is extremely thin, with a pressure of less than 0.5 nPa, and is composed of many elements. The temperature difference between day and night on the surface was extremely large. It could reach 427 degrees during the day and drop to-173 degrees at night. Orbiting around the sun in Earth's orbit, it took 58.785 Earth days to rotate and 87.969 Earth days to orbit around the sun. The revolution speed was 47.36 kilometers per second. It was the fastest planet in the solar system. Its orbit radius was about 57.9 million kilometers, and its orbital eccentricity was 0.206. It was the largest known planet in the solar system. Its rendezvous period was 115.88 days. It orbited the sun with a 3:2 spin orbital resonance. The inclination of its axis is about 1/30 degrees, and its orbit precesses 43 arcseconds more than Newtonian mechanics predict (this phenomenon is explained by Einstein's general theory of relativity). Mercury was formed about 4.5 billion years ago. It looked like the moon and had a variety of terrains. There were a large number of water ice warehouses at the poles, and its mass was about 0.025 - 0.25% of the Antarctic ice sheet. It was first observed in 1631, and as of 2023, only three space probes had visited it.
- In terms of characters, there was a woman named Mercury (her real name was Wang Yini). She was born on November 11, 1995. She was from the Jilin City in Jilin Province and had a Ph. D. in archaeology from Zhejiang University. In September 2020, she registered the watermelon video account "Mercury Visiting the Museum" to educate relevant knowledge. In March 2023, she joined the College of Archaology and Culture of Liaoning University as a teacher. Her work "The First episode" published on TikTok| What kind of high-level gifts did our country receive? Is it a private property or a national property?" It has received 2,657,000 likes. As of March 3rd, 2024, it has 4,964,000 fans on TikTok and 62,468,000 likes.
- In terms of business, there was Mercury Home Textiles, which mainly focused on the development, design, production, and sales of home textile products such as sets, quilts, and pillows. On December 3,2024, it closed at 15.93 yuan, down 0.93%. The rolling price-earnings ratio was 12.43 times, the industry average price-earnings ratio was 45.93 times, and the industry mid-value was 23.50 times, ranking 34th. As of the third quarter report of 2024, there were 5 institutions holding positions, including 4 funds and 1 other, with a total of 108.1096 million shares held and a market value of 1.559 billion yuan. According to the third quarter report of 2024, the operating income was 2.683 billion yuan,-2.57% year-on-year, the net profit was 210 million yuan,-16.80% year-on-year, and the sales gross profit rate was 41.42%.
- In astronomical phenomena, the complete term for "water reversal" was "Mercury going in reverse." Mercury would go in reverse about once every four months, and each time it went in reverse for about 20 days. This was a visual phenomenon caused by the difference in orbital inclination and speed between Mercury and Earth.
- There was also a network communication equipment supplier, Mercury, whose products covered the fields of ether network, wireless local area network, wide band access, power line communication, etc. In addition to the existing core fields of transmission, switching, and route, it was gradually entering the fields of mobile Internet terminal, digital home, network security, etc. It was committed to providing local area network and Internet access methods for the public, as well as providing equipment solutions.
