The solar wing is disassembled in orbit, the robotic arm of Tiangong Space Station is built in space, and the spacecraft can also be captured
The Manned Space Office recently released a message stating that since the Tianhe core module of Tiangong Space Station entered orbit for more than half a month, a number of platform function tests and on-orbit performance inspections of equipment for space application projects have been completed. All functions are normal and operating in good condition. Has entered the rendezvous and docking track. The performance test of the manipulator is crucial in many platform functional tests, because it determines the operational quality and efficiency of the Tiangong Space Station in the next ten to twenty years.

Scientists have studied that the human limit speed of 100 meters is 9 seconds 6, why did Bolt run 9 seconds 58?
After years of scientific exploration, it has been concluded that the maximum body temperature that the human body can withstand is 46.5°C, and the minimum limit is 13.7°C. Some scientists once said that the maximum diving height of humans is 40 meters, and the maximum speed of 100 meters is 9 seconds. 6. The ultimate height of diving has not been broken yet, while the human 100-meter limit speed has been broken by Bolt.

Reincarnated as a spider: Reincarnated with the aptitude to become a god, why is no one able to surpass the spider?
"What About Reincarnation as a Spider" is a magical explosion that makes a group of students and teachers who should be in school travel collectively to a different world. The anime starts with two timelines, the human line and the spider sub-line. If you start from the initial attribute Judging from the start, the spider child can be said to be at the bottom of the game, with 100 skill points, while the other reincarnators are only strong in terms of living environment and skill points, with about 100,000 skill points and 74,000 vampires. In fact, the reason for this situation is that each person reincarnates according to the proximity of his own soul, and the number of skill points is also related to the amount of soul. Although the initial skills and attributes are very important, the advantages are not very obvious compared to the later growth. According to the central meaning of the original text, the closer to death, the faster the upgrade, the combat ability of this world is not limited to the ability value. The key is fighting awareness.

Fuxi and Nuwa are all from Sirius? Uncover the relationship between Sirius and the origin of mankind!
As we all know, the universe is very vast. With the current level of technology, there are still many areas in the universe that are unknown to us. The earth we live on is the only celestial body that has been found to have life so far. We humans have also launched a lot of exploration about whether there is life in extraterrestrial celestial bodies? Such as the Moon, Mars, Venus, etc. But now there are many people who say that there may be life on Sirius, and it is a higher intelligent life. Sirius is the brightest of the more than 6,000 stars we can see with the naked eye in the night sky. He is about 8.6 light-years away from the earth. It is a dwarf star that emits light blue light. It was not until modern scientists observed through astronomical telescopes that he had a companion star - Sirius b.

Plankton, the earliest "aboriginal" creatures on earth!
In Greek, the word "plankton" in "plankton" is interpreted as "wanderer". In fact, plankton is a "foam carpet" of floating microorganisms. It floats like a dense bubble on the upper sea surface, allowing the phytoplankton in this carpet-like cover to get sunlight for photosynthesis. Zooplankton in the cover layer can absorb nutrients from phytoplankton.

'Magnetic greenhouse effect' changes the evolution of stars
Driven by curiosity and a scientific mission, astronomers have detected, for the first time, a huge magnetic field in a mysterious region of a star's inner layer. With the help of astroseismological techniques, they have explored the phenomenon of magnetization in the interior of a batch of stars. The magnetic field strength is calculated by means of mathematical modeling. Violent thermonuclear reactions occurred in the central regions of dozens of sampled red giants, including versions of sun-type stars in addition to the sample of red giants studied. Jim Fuller, a postdoctoral researcher at the California Institute of Technology, explained in detail the significance of the research results. Using medical device technology such as ultrasound to image the internal structure of the human body, similarly, using celestial seismology technology such as sound waves to "wave" stars. The surface is imaged to further probe the properties of the star's interior.

What does the "letter" from Cygnus mean? What is the significance of Russo's great discovery?
On May 17, the Institute of High Energy Physics of the Chinese Academy of Sciences and the Nature Journal Publishing Group jointly released a major discovery. my country's national major scientific and technological infrastructure high-altitude cosmic ray observatory Lasso has discovered a large number of ultra-high-energy cosmic accelerators in the Milky Way. And recorded the highest 1.4-beat electron-volt gamma photon from the constellation Cygnus, marking the beginning of the era of ultra-high-energy gamma astronomy.

The Nobel Prize was wrong? It was just announced last year, and it was questioned this year. Where is the basis?
In October 2020, the annual Nobel Prize was announced, half of which was awarded to Roger Penrose in physics, and the other half was split equally between Reinhard Genzel and Andrea Getz. The reason for the award of the two scientists is the discovery of the supermassive black hole at the center of the Milky Way.
