Why is China targeting asteroids?

Published

By Wu Weiren
The solar system is home not only to the eight major planets but also to an immense number of
smaller celestial bodies – asteroids and comets – varying in size, shape, and orbital characteristics.
Among them, asteroids are defined as solar-orbiting objects smaller than planets and dwarf
planets, typically inactive in releasing gas or dust. These bodies, numbering in the billions, are
often referred to as “living fossils” of the solar system’s formation and evolution. Asteroids with a
perihelion distance of less than 1.3 astronomical units (AU) are categorized as near-Earth asteroids
(NEAs).
NEAs represent one of the most significant potential threats to Earth. The United Nations has
ranked asteroid impacts among the top 20 existential threats to humanity. The prevailing scientific
consensus holds that an asteroid approximately 10 kilometers in diameter was responsible for the
mass extinction event 66 million years ago, which eradicated roughly 75 percent of Earth’s
species, including the dinosaurs. More recent examples include the 1908 Tunguska event, which
flattened over 2,000 square kilometers of Siberian forest, and the 2013 Chelyabinsk incident, in
which a meteor explosion injured approximately 1,500 people and damaged some 3,000 buildings.
While the likelihood of such catastrophic events remains low, their potential consequences are
profound. As of March 2025, 38,171 near-Earth objects had been identified, comprising 38,048
near-Earth asteroids and 123 near-Earth comets. However, due to the technical challenges of
detection, only about 1 percent of near-Earth asteroids are currently catalogued. Early in 2025,
asteroid 2024 YR4 briefly showed a 3.1 percent probability of Earth impact, triggering global
concern.
How should we respond to these “uninvited guests”?
At the third International Deep Space Exploration Conference, held recently in Hefei of Anhui
province, Chinese scientists presented their vision for asteroid exploration, planetary defense, and
resource utilization, while extending an open invitation for international cooperation.
The China National Space Administration has in recent years launched a series of feasibility
studies and preliminary programs focused on NEA detection and defense, including a formal
proposal to build a national a near-Earth object defense system. Chinese scientists have outlined a
comprehensive two-pronged strategy: first, the development of an integrated early warning system
that leverages both ground-based and space-based monitoring assets; and second, the
establishment of mitigation capabilities centered on kinetic impactors, supplemented by additional
technologies and supported by a mission response library to ensure that each credible threat can be
addressed with a pre-planned, executable solution.
China aims to conduct its first asteroid deflection demonstration mission around 2027. This kinetic
impact test has three primary objectives: to alter the trajectory of the target asteroid; to observe the
impact in detail, including velocity and energy transfer; and to monitor post-impact changes to
assess the operation’s success.
The mission involves targeting a small asteroid approximately 10 million kilometers from Earth,
aiming to change its velocity by 3 to 5 centimeters per second, sufficient to alter its trajectory. The
selected target poses no risk of Earth impact for at least the next century.
From the standpoint of planetary defense and the long-term survival of humanity, developing
asteroid mitigation capabilities is a global imperative. As a responsible major player in space,
China is committed to contributing its expertise and resources to the establishment of an
international asteroid detection and defense system.

Beyond defense, asteroid exploration and resource utilization also hold immense promise.
Asteroids contain significant reserves of iron, nickel, platinum-group metals, and water ice. They
are broadly classified into metallic, carbonaceous, and silicate types. The exploitation of asteroid
resources – long pursued by leading spacefaring nations – holds transformative economic potential.
According to authoritative estimates, over 700 of the roughly 1,000 asteroids studied in detail are
each valued at more than $100 trillion. Over the next 30 years, the projected economic value of
main-belt asteroid resources may exceed $700 quintillion.
This field is not only a strategic pillar of deep-space exploration but also a foundational
component of the emerging extraterrestrial resource economy. With ongoing advances in nuclear
space propulsion, quantum technologies, and embodied intelligence, the development of asteroid
resource is expected to become increasingly intelligent, cost-effective, and commercially viable.
In the future, a large-scale industrial chain centered on asteroid exploitation is likely to emerge,
becoming an integral part of the deep-space economy.

Former Kano State governor and 2023 presidential candidate of the New Nigeria Peoples Party, Rabiu Kwankwaso, has revealed that one of his daughters encouraged him to collaborate with former Labour Party presidential candidate, Peter Obi, during the 2023 general election.

Kwankwaso made the disclosure on Monday while speaking on Prime Time, a programme on Arise Television.

According to him, many political leaders in Nigeria have failed to understand the mindset, concerns, and aspirations of young Nigerians, especially in the era of social media.

He explained that younger Nigerians are more interested in competent and effective leadership than the ethnic and religious sentiments that often dominate political discussions among older politicians.

“So many things have changed in this country. You have leaders, many of whom don’t even realize what is happening on social media. We have leaders who hardly have any contact with young men and women,” Kwankwaso said.

“People of our age, my age, or especially the age of Atiku, are very few in this country compared to the younger people. The younger people have their own way of thinking, even our children.”

The former Kano governor stated that even within his family, younger members expressed opinions that reflected a desire for political cooperation and better leadership.

“You will be surprised, even during the 2023 election, in my own house, my own daughter was telling me to go and work with Peter Obi,” he said.

“She didn’t say she was obedient, but she wanted me to work together with him, and vice versa.”

Kwankwaso added that while many older politicians remain focused on religion and ethnicity, young Nigerians are more concerned about credible leadership and national progress.

“So you see, there is a lot happening in this country, but people at that level we are talking about don’t even understand,” he stated.

“People are talking about religion. People are talking about ethnicity. People are talking, especially those at our level and age, but the younger people are looking for the right leadership for this country. And I think they are absolutely right.”

Uba Sani has dismissed reports of a major crisis within the Progressive Governors’ Forum, describing the recent disagreement among members as a minor misunderstanding.

Sani made the remarks on Monday during an appearance on Politics Today, a programme on Channels Television.

Reports had emerged last week claiming that Hope Uzodimma was removed as chairman of the Progressive Governors’ Forum and replaced by Peter Mbah following a tense meeting in Abuja.

The reports also alleged that the forum had split into rival factions. While Uzodimma insisted he remained chairman, another bloc was reportedly aligned with Dapo Abiodun and Abdulrahman Abdulrazaq.

However, governors loyal to Uzodimma later passed a vote of confidence in him during a meeting held at the Imo State Lodge in Abuja. President Bola Tinubu was also said to have intervened in the dispute.

Reacting to the controversy, Sani, who serves as vice chairman of the forum, maintained that no leadership change had taken place.

“At the moment, there’s no problem. All the governors are together. His Excellency Hope Uzodimma is the chairman of the Progressive Governors Forum,” he said.

“My humble self, Senator Uba Sani, is the vice chairman of the Progressive Governors Forum.”

The Kaduna governor stated that disagreements are normal in a democratic setting and should not be blown out of proportion.

“In my own opinion, I don’t think it’s a serious issue, like many people try to make it look like it’s a very serious issue,” he said.

“Because, you know, in everything we are talking about democracy, people can choose to disagree and agree. So, in my own opinion, it was just a slight misunderstanding.”

Sani assured party supporters that the matter had been resolved and dismissed speculation of any division within the forum.

“I don’t think you will hear anything again. I can assure you, you can’t hear anything again,” he stated.

“It’s just a slight disagreement, not a serious issue, but a slight disagreement. But it has been resolved.”

He further added that if there had truly been a leadership change, he would have automatically assumed office as chairman in his capacity as vice chairman.

“And of course, if there’s any change of leadership, sitting here as the vice chairman, I could have taken over,” he said.

“But I can tell you, I was there. And I was the one who made that statement clear that we are united. Everything is okay.”

Former Vice President Atiku Abubakar has warned opposition parties against zoning the 2027 presidential ticket to the South, arguing that such a decision could make it easier for President Bola Tinubu to secure re-election.

Published

In a statement released by his camp, Atiku maintained that fielding another southern candidate against a sitting southern president would be politically ineffective and unsupported by Nigeria’s democratic history.

According to the statement, opposition leaders should concentrate on forming a strong and united coalition capable of defeating the ruling party rather than making what it described as emotional or symbolic political choices.

Atiku’s camp questioned how a southern opposition candidate could realistically defeat a southern incumbent president.

“At the core of the question is: how does a Southern opposition candidate realistically unseat a sitting Southern president?” the statement read.

It further argued that Nigeria’s political history offers no example of such an outcome, warning that insisting on that strategy could amount to entering the election already defeated.

The statement added that if opposition parties insist on zoning the presidency to the South, they might as well allow Tinubu to seek re-election unchallenged by a rival candidate from the same region.

According to Atiku’s camp, such a strategy lacks the political strength, national spread, and electoral advantage needed to unseat an incumbent president.

The former vice president’s camp also criticised supporters of southern zoning, describing their position as “intellectually dishonest” and disconnected from present political realities.

“Defeating an incumbent president requires realism, not romanticism; strategy, not sentiment; honesty, not selective memory,” the statement added.

It urged opposition politicians to decide whether their focus is on making symbolic political statements or genuinely winning power in the 2027 election.

The statement stressed that opposition politics should be driven by practical electoral calculations and broad national coalition-building rather than emotional considerations.

On the issue of fairness and power rotation, Atiku’s camp argued that by 2027, the South would have spent more years in power than the North during Nigeria’s current democratic dispensation.

According to the statement, the South would have occupied the presidency for 18 years, while the North would have held power for only 10 years within the same period.

“It becomes difficult to understand the justice in an argument that seeks to deepen an already existing imbalance under the guise of equity,” the statement noted.

The camp also accused some supporters of southern zoning of selective memory, recalling that many of them backed former President Goodluck Jonathan in 2011 despite calls at the time for power to return to the North.

“It is intellectually dishonest for those who supported a Southern presidency in 2011 to now posture as custodians of rotational justice,” the statement said.

While acknowledging the Southeast’s aspiration to produce Nigeria’s president, Atiku’s camp criticised what it described as “transactional political bargaining” and “symbolic tokenism.”

The statement warned against political arrangements allegedly aimed at satisfying personal ambitions without creating a genuine and sustainable pathway for the Southeast to attain power.

“Principles do not become sacred only when they align with personal ambition,” the statement concluded.

It urged opposition parties and stakeholders to focus on building a broad-based national alliance capable of defeating Tinubu in 2027 rather than becoming distracted by divisive zoning debates.
