At 15:00 on December 17, 2023, Beijing time, the hyperbolic No. 1 commercial launch vehicle was launched from the Jiuquan Satellite Launch Center in China, and the DEMOCRAT No. 1 satellite on board was smoothly sent into the scheduled orbit, and the launch mission was a complete success.

It is reported that “Double Curve No. 1” is the first private commercial launch vehicle in China to successfully enter orbit, and it has unfortunately experienced three consecutive failures after its successful maiden flight, and finally regained its success in the launch of the Remote Six rocket in the first half of this year.

“Double Curve One” is a small four-stage solid launch vehicle developed by Star Glory, 24 meters long, one to four stages, fairing diameter are 1.4 meters, takeoff mass of about 42 tons, takeoff thrust of about 79 tons, its near-Earth orbit (LEO) capacity of 0.38 tons, 500 km sun-synchronous orbit (SSO) capacity greater than 0.3 tons, 700 km sun-synchronous orbit (SSO) capacity greater than 0.3 tons, 700 km sun-synchronous orbit (SSO) capacity greater than 0.3 tons. Its LEO capacity is 0.38 tons, 500 km SSO capacity is more than 0.3 tons, and 700 km SSO capacity is 0.225 tons.

Previously, the “hyperbola one” launch offer of 5 million U.S. dollars (the current exchange rate of nearly 36 million yuan), based on the arrow near-Earth orbit capacity calculation, the unit launch offer of about 13,000 U.S. dollars. However, with the delivery of the rocket batch production, the launch offer there is a large space for decline.

At present, Star Glory’s “Hyperbola II” rocket has completed two vertical take-off and landing missions, realizing China’s first reusable technology validation rocket reuse flights, and providing a good opportunity for the company’s ongoing development of the medium-to-large-sized reusable launch vehicle “Hyperbola III” to provide a good opportunity for the development of “Hyperbola III”. It has provided key technology verification for the company’s ongoing development of the medium- to large-sized reusable launch vehicle “Double Curve III”.

It is expected that in 2025, the “Hyperbola III” rocket will achieve its first flight, with a take-off mass of 490 tons and a near-Earth orbit capacity of 13.7 tons, which will provide powerful capacity support for China’s constellation network launches.

According to media reports, the owner of the Tesla that crashed into 11 cars in a row said in a new interview that he had just gotten a license plate on the day of the accident on the morning of Nov. 25, and that he didn’t have Autopilot or single-pedal mode on at the time.

According to the owner’s own words, the vehicle suddenly picked up speed when passing through the subway station intersection, and he lost the ability to control the car.

At present, Mr. Wang’s vehicle in the traffic control department for technical appraisal, he also contacted the car brand, the brand said there will be after-sales department to follow up the matter.

This also triggered a heated discussion among netizens, some netizens said, from the video brake light is on, so it is caused by brake failure, there are netizens said, the brake light is on does not mean it is brake failure.

There are also netizens science said, new energy vehicles have the “kinetic energy recovery” function, that is, in driving, see the red light ahead, we if this time, let go of the gas pedal, the vehicle will automatically carry out the kinetic energy recovery, the speed will be reduced, this function may lead to do not step on the brakes will also make the brake light on.

If it is not because of brake failure and lead to loss of control of the vehicle, then the cause of the accident may also be caused by improper operation or distraction of the driver, so what do you think about this matter?

The morning of November 27, 2023, Malaysia Airlines MH370 lost related cases in Chaoyang District People’s Court officially opened hearing, the case for the “air transport damage liability disputes”. 27 morning at 8 o’clock, the poster news reporter in front of the Chaoyang District People’s Court to see that a number of families of the missing passengers have been waiting for the opening of the court, which There is no lack of elderly people.

On March 8, 2014, Flight MH370 carrying 239 people (including 153 people from mainland China and 1 person from Taiwan) was lost on its way from Kuala Lumpur to Beijing, which is known as “the biggest mystery in aviation history”.On January 29, 2015, the Malaysian Civil Aviation Authority (MCAA) announced that the Malaysia Airlines Flight MH370 had crashed and presumed that the 239 passengers on board had been lost. It is presumed that all 239 passengers and crew on board were killed.

Over the years, this incident has always touched the hearts of countless people in the country. Many families of the missing passengers have never given up searching for their loved ones, and many of them have traveled to Malaysia, Australia, Madagascar, and other places to look for them, while also hoping to seek justice through legal channels to promote the search.

After nearly a decade, they are finally waiting for the case to begin. “It’s been nearly 10 years since the incident, and I’ve received my first notice of an official court hearing.” In mid-November, a number of family members of the lost Chinese passengers were notified of the official court hearing. It is reported that the cases of about 40 families of the lost Chinese passengers will be held in court from Nov. 27 to Dec. 6 at the Chaoyang District People’s Court in Beijing.

“Each family has different claims and demands different amounts of compensation, and no one will represent anyone, so it’s each passenger’s family member who will have separate hearings.” According to some of the families of the plaintiffs of Malaysia Airlines, Zhang Qihuai disclosed that the defendants in this trial there are five companies: the first party is the reorganization of the former Malaysia Airlines, the second party is the reorganization of the new Malaysia Airlines, the third party is the aircraft manufacturer Boeing, the fourth party is the aircraft engine manufacturing company Rolls-Royce UK, and the last party is the underwriting of Germany’s Allianz Insurance Group for the Malaysian Airline.

Many of the families of the missing passengers, whether in interviews or on social media platforms, have said that “finding people is always the first demand”. At the same time, in addition to requesting the responsible party to make positive compensation, they also hope that the official establishment of a search fund, the families to continue to monitor the search for their missing relatives, to resume psychological assistance to the families of the missing passengers, to restore the liaison organization with the families, and so on.

The families of the missing passengers have expressed the hope that a final or intermediate judgment will be rendered as soon as possible in order to alleviate the difficulties of the families in their existential circumstances, to comfort the deceased who have died in peace over the past decade, to punish the perpetrators and the perpetrators, to promote the search, to promote the progress of the incident, and to fulfill the ultimate wish of the families to “find them by all means”.

Recently, rumors about the GeForce RTX 40 Series SUPER have been growing. According to reliable sources, NVIDIA has confirmed the release date of this new graphics card and will officially launch it at the big CES 2024 show early next year. There are three models of GeForce RTX 40 Series SUPER being released, namely RTX 4080 SUPER, RTX 4070 Ti SUPER and RTX 4070 SUPER.

One of the most confusing aspects of the RTX 4070 Ti SUPER is the combination of “Ti” and “SUPER” in the model name. Many gamers thought that this naming scheme was unprecedented and even considered it a fake news. However, a netizen recently revealed the packaging design of the new graphics card, which seems to confirm that this combination does exist.

Judging from the design, NVIDIA has made some changes to the RTX 4070 Ti SUPER’s model number logo, while retaining the original font, the “Ti” and “SUPER” are juxtaposed together with a silver frame as the base color. In addition, “SUPER” is more prominent and larger than “Ti” in the model number labeling. According to the information summarized so far, the card is equipped with AD103-275 or AD102-175 chipset, 48MB L2 cache and 8448 CUDA cores.

As for other specifications, no specific details are known at the moment. Information such as the frequency of the product as well as pricing will have to wait for NVIDIA’s official release to be revealed. However, it is certain that this new product will have a certain degree of improvement, including performance and power consumption optimization.

A research team from Tsinghua University, together with its partners, has successfully broken through the physical limitations of traditional chips. They innovatively proposed a new computing framework for optoelectronic fusion, and developed the international first all-analog optoelectronic intelligent computing chip (ACCEL for short). Experiments have shown that the chip has more than 3,000 times the arithmetic power of current high-performance commercial chips in intelligent visual target recognition tasks.
This ultra-high-performance all-analog optoelectronic intelligent computing chip has made breakthroughs in three international challenges, such as large-scale computational unit integration, high-efficiency nonlinearities, and high-speed optoelectronic interfaces. At the same time, it is characterized by high energy efficiency and high speed.

To ensure the reliability of the experimental data, the research team conducted large-scale real-world measurements and verification. For the first time, they applied end-to-end cross-layer collaboration technology to intelligent visual interaction, and utilized equivalent arithmetic power to accurately assess energy efficiency performance and latency data.
The ACCEL chip has three major advantages: first, its system-level computing power reaches 3,000 times that of existing high-performance chips. If this is compared to the time of transportation to analogize the information flow calculation, it is equivalent to shortening the 8-hour Beijing-Guangzhou high-speed railway to 8 seconds. Second, it has a system-level energy efficiency of 74.8 Peta-OPS/W, which is a 4 million times improvement over existing high-performance GPUs, TPUs, and other computing architectures. In other words, the power required to work for one hour with existing chips can be used to work for ACCEL for more than 500 years.
In addition, the production cost of ACCEL is only a few tenths of the latter, and the materials used are relatively simple and easy to obtain. These features make ACCEL cheaper.
By breaking through the physical bottleneck of traditional chips and introducing optoelectronic fusion technology, Tsinghua University’s research team has successfully developed the world’s first all-analog optoelectronic intelligent computing chip, ACCEL, which is an ultra-high-performance, low-power, and low-cost chip that opens up new paths for ultra-high-performance computer development.

At the main forum of the annual meeting of the Chinese Association for Science and Technology (CAST) held in Hefei City, Anhui Province, China, on October 22, Wu Weiren, chief designer of China’s lunar exploration project, director and chief scientist of the Deep Space Exploration Laboratory (DSEL), and an academician of the Chinese Academy of Engineering (CAE), introduced China’s plans for deep space exploration in the next 15 years.

Academician Wu revealed that in the next 15 years, China’s deep space exploration will demonstrate the implementation of ten major engineering tasks in three areas, including lunar exploration, planetary exploration, and transportation technology.

Specifically, these include: Chang’e VI/VII/VIII Lunar Exploration Project Phase IV, International Lunar Scientific Research Station, manned lunar landing, Magpie Bridge Teleconducting Remote Integrated Constellation System, Tianwen II Asteroid Sampling and Detection, Near-Earth Asteroid Defense, Tianwen III Mars Sampling, Jupiter Galaxy and Interplanetary Transit Detection, and Solar System Marginal Detection.

In the field of transportation, China will demonstrate the implementation of the heavy-lift launch vehicle project, breakthroughs in key technologies such as 10-meter-class rocket body diameter and high-thrust liquid-oxygen methane engines, so as to raise China’s near-Earth orbit launch capacity from 25 tons to 150 tons, laying a solid foundation for future deep-space exploration.

Among them, the defense of near-Earth asteroid party, will be for near-Earth asteroid impact on the Earth, a very small probability, a great danger of the event, a tens of millions of kilometers of asteroid implementation of kinetic energy impact, so that it changes the orbit, and on-orbit to carry out the assessment of the effect of the impact.

Prior to this, Chen Qi, director of China’s Deep Space Exploration Laboratory System Research Institute, had disclosed the development blueprint of near-Earth asteroid defense, planning to achieve a kinetic energy impact on an asteroid in 2030, and to realize the push-off deflection during 2030-2035, and to have preliminary asteroid orbit control capability before 2045.

Wu Yanhua, deputy director of the National Space Administration, said that China will begin to set up a near-Earth asteroid defense system to jointly respond to the threat of near-Earth asteroid impacts, contributing Chinese power to protect the Earth and human security.

China’s first near-Earth asteroid defense mission is expected to achieve three major scientific goals:
The first is to reveal the dynamical evolution law of the impact target and detect the orbital characteristics of the target asteroid.
The second is to reveal the intrinsic properties of the impact target and to detect the shape, size, composition and structure of the target asteroid.
The third is to reveal the impact momentum transfer law, and carry out research on wall impact effects such as terrain changes and spatter distribution.

On September 27, 2022, NASA conducted the first asteroid defense exercise in human history, using a satellite named “DART” to impact a 160-meter-diameter asteroid 11 million kilometers away and change its orbit.
