By Yu Sinan, Li Yi, Zhang Wei

In the early hours of May 29, China successfully launched its first asteroid sample-return mission, Tianwen-2, from the Xichang Satellite Launch Center in southwest China’s Sichuan province, an endeavor designed to shed light on the formation and evolution of asteroids and the early solar system.

The Tianwen-2 mission aims to achieve multiple goals over a decade-long expedition: collecting samples from the near-Earth asteroid 2016HO3 and exploring the main-belt comet 311P, which is more distant than Mars.

The mission includes 13 flight stages and will reach a distance of approximately 150 million to 500 million kilometers from Earth, marking a major step forward in China’s deep space exploration endeavors.

Known as a quasi-satellite of Earth, the asteroid 2016HO3 orbits the Sun and appears to circle around Earth as well, remaining a constant companion to our planet. Its relatively stable orbit requires lower energy requirements for spacecraft to reach it, while enabling a viable scenario for subsequent exploration of the main-belt comet 311P.

Scientific research suggests that the asteroid 2016HO3 may preserve primitive materials from the early solar system. Investigating this asteroid could yield valuable insights into the composition, formation, and evolutionary history of the solar system’s early materials.

The second target, 311P, a celestial anomaly discovered in the mainasteroid belt between Mars and Jupiter, occasionally spews out materials and resembles a comet with tails. While it exhibits compositional traits with traditional comets, it maintains the orbital characteristics of an asteroid. Exploring this unique object will deepen human understanding of the composition, structure, and evolutionary mechanisms of small celestial bodies.

Tianwen-1 marked China’s first Mars exploration mission, successfully achieving orbiting, landing, and roving operations in a single mission. Tianwen-2, however, has a different set of objectives and faces new technical challenges.

First, the Tianwen-2 mission will conduct sampling under weak gravity conditions. Observational data suggest that the asteroid 2016HO3, with an average diameter of about 41 meters, exists in near-zero gravity and rotates rapidly. Given these complex conditions, it is extremely challenging for the probe to achieve stable attachment with the asteroid and sampling within a limited time.

Second, the mission involves vast distances. Asteroid 2016HO3 is located about 18 million to 46 million kilometers from Earth, while the main-belt comet 311P lies approximately 150 million to 500 million kilometers away. The immense distance from Earth imposes stringent requirements on the probe’s communication system, trajectory design, power management, and the capability to maintain highly reliable long-term operational performance.

Furthermore, there is uncertainty regarding the exploration target. Current observations of the asteroid 2016HO3 provide limited information on its rotational behavior and surface characteristics, which significantly complicate the design of both the spacecraft and its sampling methods.

Tianwen-2 is equipped with 11 scientific instruments, including cameras, a visible and infrared imaging spectrometer, a thermal emission spectrometer, and a detection radar, all designed to facilitate scientific data collection during the mission.

In previous missions sending payloads into the Earth’s orbit, a rocket is required to achieve a separation velocity equal to the first cosmic velocity, or approximately 7.9 kilometers per second.

However, this mission requires a separation speed exceeding 11.2 kilometers per second, known as the second cosmic velocity, to escape the Earth’s gravitational influence, necessitating high speed and energy.

After evaluating the rocket’s payload capacity, performance capability, and reliability, Long March-3B was chosen as the dedicated vehicle for the Tianwen-2 mission.

As the primary launch vehicle for China’s high-orbit launches, the Long March-3B has completed 108 missions, including key lunar missions such as Chang’e-3 and Chang’e-4.

Experts noted that asteroids are characterized by their small size, low mass, and weak gravity, making them challenging to capture and requiring exceptional precision in the rocket’s trajectory. During this launch, the rocket reached a speed of 11.2 kilometers per second, with a permitted speed deviation of no more than one meter per second, which could otherwise lead to a positional error of up to one million kilometers.

“Achieving such trajectory precision is akin to shooting a basketball from Shanghai to hit a hoop in Beijing, while ensuring the ball’s angle and speed upon entering the hoop are correct,” said Wei Yuanming, an expert with China Aerospace Science and Technology Corporation.

To tackle this challenge, the rocket design team spent two years completing multiple design iterations so as to achieve seamless “handoff” between the rocket and the probe, Wei added.

Shantou taps new growth momentum via AI token exports

Published

on

By Li Gang, People’s Daily

As artificial intelligence (AI) accelerates the transformation of global industries, a new form of digital trade is emerging in the southern Chinese city of Shantou: exporting computing services measured not in physical goods, but in AI tokens.

In late April, Shantou, Guangdong province completed full-chain verification for what has become known as “token exports” — a model in which computing power remains within China while high-value AI services are delivered to overseas users. Within just one month, average daily token usage surged from 100 million to the tens-of-billions level.

The practical application of this model is already well underway. 

Recently, when a user in Singapore activated an AI-powered toy and gave a simple command — “Tell me a fairy tale” — the spoken command traveled through the network directly to a dedicated overseas computing zone inside a computing center in Shantou. 

Local deployed AI agents wrap up speech recognition in under one second and craft custom story content, firing the finished audio back to the Singapore-based toy device in as little as 0.1 seconds.

The user repeated the process multiple times, eventually listening to five stories in total. Approximately 100,000 tokens were consumed during the interaction and billed in real time at a rate of 2 yuan ($0.3) per one million tokens.

When payment arrived, a complete commercial cycle was achieved, marking the successful realization of Shantou’s “token export” model.

Tokens represent the smallest discrete calculation unit for large AI models to process information. They have become a key indicator of intelligent computing capacity and, increasingly, a new carrier of value in the digital economy.

Inside the China (Shantou) Pilot Zone for Economic and Cultural Cooperation with Overseas Chinese, token exports are already transforming the economics of electricity.

Today, overseas users across multiple countries and regions in Southeast Asia are accessing token services generated in Shantou.

“Data flows in from abroad and all processed outputs head back overseas, with zero compromise to end-user experience,” explained Cai Qichen, an engineer at the Shantou Branch of wireless carrier China Mobile. “Token costs have already been integrated into product service packages, making future usage more convenient.”

According to estimates from toy manufacturer SHOWMAC based in Shenzhen, Guangdong province, using Shantou’s computing services reduces costs by more than 30 percent compared with directly purchasing overseas computing resources.

Meanwhile, inside computing centers, turning electricity into AI tokens delivers dramatic value appreciation. A kilowatt-hour of electricity, which comes at a cost of roughly 0.5 yuan($0.07) , can be transformed through AI computing into tokens and then exported at a price of 11 yuan($1.6), representing a twenty-two-fold increase.

As one of eastern Guangdong’s major offshore wind power bases, Shantou has already connected 1.2 million kilowatts of installed capacity to China’s power grid.

The electricity itself does not need to cross borders. Computing power remains within China. What gets exported instead are high-value digital services, turning electricity into a form of hard currency for cross-border digital trade.

Ultra-low network latency forms the technical backbone making token exports feasible.

“More than half of China’s outbound bandwidth carried by international submarine cables lands in Shantou, and the city is also home to five undersea trunk cables linking destinations worldwide,” said Hong Zhebin, chief technology officer of the international submarine cable landing station operated by the Shantou branch of wireless carrier China Telecom.

“The latency between Shantou and Singapore is only 32.7 milliseconds, quicker than the blink of an eye,” Hong added.

Hong Yu with the Shantou Branch of China Mobile, added that Shantou’s overseas computing services offer stable response speeds, regulatory compliance, and substantial cost advantages.

“Our pricing is only 1/3 to 1/2 that of mainstream international platforms, while customer retention exceeds 70 percent,” Hong told People’s Daily.

Yet building a complete end-to-end system is only the starting point. Shantou is now attempting to transform itself from a transit city for digital infrastructure into an ecosystem hub.

Leading computing companies and developers are gathering rapidly. Pilot platforms have passed acceptance reviews. Commercial closed loops have already emerged in applications ranging from AI toys to intelligent manufacturing, with large-scale operations expected soon.

Shantou’s Chenghai district has long been known as the “toy capital of China.” As AI becomes increasingly integrated with the toy industry, the city has launched an AI toy innovation center and the Shantou AI Laboratory, striving to become the “AI toy capital of China.”

At the exhibition space of one local tech firm sits Amy, an AI desktop robot capable of fluid multilingual conversation.

“It is equipped with a multilingual intelligent voice interaction system capable of real-time recognition and conversation in dozens of languages,” said the company’s general manager Chen Ruifeng.

The technology has already been integrated into multiple AI toy products exported to countries including the United Kingdom, Russia, and Japan.

Shantou’s token export model allows AI toy manufacturers to access domestic large language models at costs far below those of overseas alternatives.

“The cost of using overseas AI models can be dozens of times higher than domestic models,” Chen said. The company’s AI toys currently run on Chinese large models including DeepSeek and Doubao.

“Token exports have significantly increased both product value-added and international competitiveness,” he said.

The Shantou branch of wireless carrier China Unicom, together with a Guangdong-based tech firm, has established dedicated lines connecting Shantou and Vietnam, delivering cross-border computing services to Aachen Sv, a Chinese-invested fiber-optic company operating in Vietnam.

Vietnamese users accessing large models such as DeepSeek and Qwen experience extremely low latency with zero packet loss. “In less than a month, more than a dozen companies have approached us for consultations,” an employee of the Guangdong-based tech firm said.

Meanwhile, the Guangdong branch of China Mobile has launched an OpenClaw intelligent agent framework, providing integrated AI service packages that allow traditional toys to complete intelligent upgrades in as little as 15 days.

From toys to textiles, cross-border e-commerce, and high-end manufacturing, tokens are increasingly becoming the digital fuel powering Shantou’s industrial upgrading.

Sanxingdui Museum transforms ancient relics into interactive experiences

Published

By Song Haoxin, People’s Daily

What if museum visitors could truly interact with cultural relics rather than merely observe them through glass displays? At the Sanxingdui Museum in southwest China’s Sichuan province, a specially designed interactive hall is revolutionizing cultural engagement.

Within this 1,300-square-meter space, nearly every exhibit invites touch, operation, or participation. Visitors immerse themselves in installations inspired by the ancient Shu civilization, blending education with entertainment.

By trying on replicas of headwear on bronze statues discovered in Sanxingdui Ruins, for example, visitors can not only take photos of themselves but also learn about the symbolic meanings behind different headpieces. 

Guests can don replicas of bronze statue headwear from the Sanxingdui Ruins, learning their symbolic meanings while capturing photos. Augmented reality allows dancing alongside virtual Sanxingdui figures for social media sharing. A creation zone even enables “time travel” to experience ancient bronze-casting and construction techniques.

These innovations transform traditional museum visits, offering deeper cultural understanding through hands-on interaction. “This hall emerged from extensive brainstorming,” explained Zhu Yarong, deputy director of the management committee of the Sanxingdui Ruins site. 

“We’re transitioning from passive relic viewing to interactive engagement, bridging the gap between audiences and history.”

Previously, museum experiences were largely one-directional with limited engagement. Visitors viewed relics through display cases, usually stopping mainly to take photographs, with relatively limited forms of engagement. By liberating artifacts from display cases into interactive settings, Sanxingdui is pioneering a shift from didactic presentation to open cultural dialogue.

Traditional exhibition spaces remain popular, while digital innovations attract growing interest. A VR project employs digital twin technology to recreate 1:1 scale excavation sites — complete with protective shelters and cabins — placing visitors at the archaeological forefront.

Another project, Heaven and Earth Echoes — Sanxingdui Panoramic Sound and Vision Digital Art Theater, features an interactive panoramic LED dome with a diameter of 20 meters and a resolution approaching 16K. The massive dome creates a deeply immersive atmosphere. By waving digital torches in their hands, visitors can trigger sacred birds to circle above them across the dome, experiencing the ancient Shu civilization through an interplay of sound and imagery.

“The digital technology made me feel as if I were racing across the Mamu River. That sense of traveling through time was incredible,” said Hao Yong, a tourist from southwest China’s Chongqing municipality who came specifically to experience a virtual reality program.

From passive observation to active participation, Sanxingdui Museum continues introducing new interactive experiences that transform cultural relics into living carriers of dialogue and engagement, helping keep the sparks of Chinese civilization alive for new generations.

A living testimony about MKA: The Aondoakaa that I know Written By Brahms Tor-Ikuan

Published

By

My people of Benue State,

I am not speaking to you today as a politician. I am speaking as a brother whose family was held up by Chief Mike Kaase Aondoakaa, MKA, when we had no one else to hold onto.

My elder brother, Verem Ukaa-Ikuan, was not just my blood. He was a very dear and close friend to Chief MKA. When my brother fell ill and was diagnosed with liver damage caused by poisoning, MKA didn’t treat it as someone else’s problem. He took it on as his own.

He worked closely with Verem during his time as Attorney General of the Federation, and when the sickness came, he moved immediately. Searches were conducted, and Apollo Hospital in India was earmarked for a liver transplant. Every travel arrangement was made personally by Chief MKA.

But we hit a wall. Verem was too weak to fly a long commercial flight. Only an air ambulance could get him to India alive. At that time, there was only one functional air ambulance in the entire country, owned by Julius Berger. It was completely out of reach for even the most high-profile citizens.

Chief MKA went all out. He did not give excuses. He did not delay. He used every connection and every ounce of influence he had to secure that air ambulance for my brother.

On the day it was secured, Barr. Terna Yaji, his Senior Special Assistant, called me a few minutes after 6pm. He told us to prepare Verem for departure and take him to Makurdi airport very early the following morning. I informed him, my brother passed on at exactly 6 o’clock a few minutes ago. I told Barr. Terna Yaji, and I saw a devastated MKA.

During the burial, Chief MKA was out of the country on national assignment. He was pained that he could not be there physically. His entire team, led by the late Onov Tyuulugh, represented him fully. And his message to us at the burial has never left me:

“If death were law, as the Attorney General, a law would have been made no matter what to ensure Verem will just not die but live forever.”

That is who Mike Kaase Aondoakaa is when nobody is watching. He does not abandon his people. He does not forget. He stood with our family then, and he has stood with us till date.

Now he is asking for the chance to govern Benue State.

Benue needs a governor with a heart like that. A governor who fights for you even when there’s no political gain. A governor who sees you as family, not as a vote.

I am standing with Chief Mike Kaase Aondoakaa for Governor of Benue State.
For compassion that moves to action.
For loyalty that does not fade.
For leadership that proves itself in the darkest hour.

Join me. Let us give Benue a leader who has already shown what he will do for us.

God bless Chief Mike Kaase Aondoakaa.
God bless Benue State.

Brahms Tor-Ikuan, a beneficiary of MKA’s benevolence writes from Makurdi
