In recent days, at the Institute of Deep-Sea Sciences and Engineering of the Chinese Academy of Sciences in Sanya, staff have been busy, nervous and excited to welcome home their colleagues who have been adrift at sea for nearly two months. The Haidou Abyss Scientific Expedition Team, which was on a mission in the waters of the Mariana Trench, returned to Sanya, Hainan Province, on the "Exploration No. 1" scientific research vessel.
On August 24, the 59-member scientific expedition team from Sanya completed a total of 87 stations and 504 kilometers of bathymetric line operations in the Mariana Trench from multiple disciplines such as deep-sea equipment and technology, geophysics, marine geology and geochemistry, marine biology and physical oceanography.

Ali's "Candy Candy" mini space station was officially launched
“5...... 4...... 3...... 2...... 1...... Ignition!" This is the countdown sound coming from the intercom of the Taiyuan Satellite Launch Center at 6:57 a.m. on October 25.
Suddenly, a flash of fire and a huge yellow smoke appeared, and the Long March 4B carrier rocket carrying Alibaba's "Candy Candy" mini space station officially lifted off.
The Candy Candy Jar successfully entered the predetermined orbit. According to the plan, the working hours of this cube small iron box on the predetermined orbit will run through the entire 2018 Tmall Double 11, sending a happy signal from space to consumers around the world.
A dozen days ago, the 20-kilogram "Candy Candy Can" was escorted by engineers from Shanghai by plane to the Loess Plateau in central Jinzhong, and after a bumpy ride of four or five hours, it finally arrived at the Taiyuan Satellite Launch Center and was placed in the rocket's exclusive last sub-class cabin.
Ali revealed that the reason why the mini space station was named "Candy Candy Can" is closely related to the theme of "Happy" on Tmall Double 11 this year - candy means the simplest happiness of everyone's childhood, and the candy candy can is a container for storing happiness and beauty.

The AG600 successfully completed its first water flight mission and returned to Zhuhai
On the morning of October 25, China's first large amphibious aircraft, the Kunlong AG600, successfully completed its first water flight mission, returned to Zhuhai from Jingmen Zhanghe Airport in Hubei Province.
At 10:30 on the same day, the sky in Zhuhai was clear and the autumn breeze was gentle, and the people who greeted the AG600 "home" at the Aviation Industry Tongfei South China Base were looking forward to it. At about 10:57, with a loud roar, the AG600 landed smoothly on the airport runway, slowly entered and moored on the tarmac of the Aviation Industry Tongfei South China Base. At 11 o'clock, the four crew members on the first flight mission stepped off the plane in turn, and the scene suddenly burst into warm applause.
The aircraft rolled off the assembly line in Zhuhai on July 23, 2016, successfully completed its first overland flight in Zhuhai on December 24, 2017, and successfully completed its first water flight on October 20, 2018 in Jingmen, Hubei Province.

Scientists are committed to developing human hibernation drugs

Bears hibernate, marmots, squirrels, turtles, and other animals hibernate, but humans, who are spirits of all things, don't—at least not yet.
However, this may be slowly changing. According to NBC recently reported, scientists who have deeply explored the hibernation genes of animals believe that they may be able to release the same biological superpowers, such a miracle is not only expected to improve the level of medical services, but also to help astronauts travel to Mars and other deep space destinations in their slumber.
Scientists believe that the ability to hibernate first appeared in the first generation of distant mammals, a furry arboreal animal that lived 65 million years ago, and eventually passed on to the vast majority of modern mammals, including humans. If this assumption is correct, then the secret of hibernation may be lurking in the human genome.

Don't think of Jupiter stripes as superficial, mysterious
▲ Jupiter and the Juno probe NASA
Recently, the Mercury probe "Beppe Colombo" has attracted people's attention. This is the second dedicated Mercury probe launched by humans. In fact, humans have sent many probes to the planets of the solar system for in-depth observation. Jupiter, for example, launched the Pioneer 10 probe by nasa in 1973, and has conducted 7 overflight observations and 2 specialized exploration missions in the past 45 years. Among them, the cause of the striped structure on the surface of Jupiter has always been the focus of detection.
This year, Israeli scientists concluded based on Juno's data that Jupiter's stripes stem from fluid motion within it. But studies by scholars such as Kong Dali, a researcher at the Shanghai Astronomical Observatory of the Chinese Academy of Sciences, have found that the answer is not so simple. The results were published in the latest edition of the Proceedings of the National Academy of Sciences.

NASA shows the rocket cooling process releasing 450,000 gallons of water a minute
On October 24, nasa publicly demonstrated the rain system used by NASA's Kennedy Space Center for space launch system (SLS), which, like a giant fountain, released 450,000 gallons of water into the 39B launch pad in less than two minutes. In the video, a rapids rush straight into the sky, about 100 feet high, but within seconds it becomes a trickle.
SLS costs $8.9 billion, and NASA is preparing for its first launch mission. The rocket system will launch heavy-duty, high-thrust rockets, while about 450,000 gallons of water will be needed to cool down and reduce noise during its ignition and launch. NASA will use the rain system in the video to protect the rocket and its associated facilities, including the Orion spacecraft, the mobile launcher, and the launch pad itself. NASA explained that rushing a fast-flowing stream of water towards the launch pad relieves the extreme heat and energy generated by the rocket launch.
