A controversial Chinese biophysicist, who had been imprisoned after creating the world’s first gene-edited babies, had his Hong Kong work visa revoked after immigration officials suspected he lied on an application form for a talent scheme.

He Jiankui, who sparked an international scientific and ethical debate in 2018 when he revealed he had created the world’s first “gene-edited” babies resistant to HIV, said at the time at an international conference in Hong Kong that he had modified two embryos before they were placed in their mother’s womb.

The scientist said he used a technology known as CRISPR-Cas9 to alter the embryonic genes of twin girls before birth. He said he had targeted a gene known as CCR5 and edited it in a way he believed would protect the girls from infection with HIV, the virus that causes AIDS. It later emerged that a third gene-edited baby had been born.

The former associate professor at the Southern University of Science and Technology — who has since been fired — was later accused of having forged approval documents from ethics boards. He was sentenced by a Chinese court to three years in prison in late 2019 for illegally carrying out human embryo gene-editing intended for reproduction. He was released in April 2022.

The scientist posted on the Chinese social media platform WeChat on Saturday that he had been granted the visa on February 11 under the talent scheme. It was aimed at attracting people with rich work experience and good academic qualifications from all over the world to explore opportunities in Hong Kong.

He said he would conduct gene-editing research using artificial intelligence and was “optimistic about [the future of] Hong Kong,” reported the South China Morning Post. His original post cannot be found.

“We plan to use artificial intelligence tools to evolve the adeno-associated virus (AAV) capsids to improve the efficiency of gene therapy and promote affordable gene therapy for rare diseases,” he was quoted by the paper as saying. AAV is a small virus that has emerged as the most promising platform for gene therapy.

Scientists engineer the outer protein shell of AAV, known as capsid, to improve targeting and efficacy.

In response to the furor, the Hong Kong government issued a late-night statement on Tuesday, saying the visa of an individual who “made false representation” has been rescinded and a criminal investigation launched. Officials did not name He but made reference to media reports regarding an applicant being granted a visa “despite having been imprisoned for illegal medical practice.”

“After reviewing the application, the Immigration Department suspected the visa/entry permit was obtained by false representation, and the Director of Immigration had declared the visa/entry permits invalid in accordance with the law, and would conduct a criminal investigation to follow up,” said the statement.

The statement also warned that applicants who give false information face a maximum sentence of 14 years in prison and a fine of $17,842 upon conviction. The government has also issued a new requirement that future applicants under the visa scheme must declare whether they have any criminal records.

Since his prison release 10 months ago, He has established a laboratory in Beijing dedicated to developing affordable drugs for rare genetic diseases. Although He insisted that his work was to help people, international medical experts have criticized his gene-editing procedure as risky, ethically contentious and medically unjustified with inadequate consent from the families involved.

In a study published in the journal Nature Medicine in June 2019, scientists found that people who have two copies of a so-called “Delta 32” mutation of CCR5 — which protects against HIV infection in some people — also have a significantly higher risk of premature death.

He told The Guardian newspaper early this month that he moved “too quickly” by pressing ahead with the gene-editing procedure but stopped short of apologizing. He declined to elaborate on what measures should have been taken but said he would give further details at a scheduled talk on the use of CRISPR gene-editing technology at the University of Oxford next month.

He then said in a Twitter message on February 10 that he was “not ready to talk about my experience in the past three years, so I decided that I will not visit Oxford in March.”

Researchers in Kenya say they’ve detected an invasive mosquito that can transmit malaria in different climates, threatening progress to fight the parasitic disease. Kenya’s Medical Research Institute this week urged the public to use mosquito nets and clean up areas where mosquitos can breed.

Kenya has detected the presence of a new malaria carrier, which was first discovered in the region in Djibouti in 2012.

The new carrier, the Anopheles stephensi mosquito, transmits plasmodium vivax, the parasite the causes the deadliest type of malaria.

Bernhards Ogutu is a chief researcher at Kenya Medical Research Institute. He says it was only a matter of time before the mosquito was discovered in the country after it appeared in Ethiopia and South Sudan.

“We’ve not been able to pick plasmodium vivax which is found in Asia and Kenya. It’s there in Ethiopia and this vector can also transmit it,” said Ogutu. “So that will also look at whether we might have plasmodium vivax in coming up with this new vector showing in our place. Vivax is more difficult to treat in that you can get treated and real up because it keeps staying in the body and the liver.”

Malaria affects over 229 million people each year and kills over 400,000 people, according to the World Health Organization.

More than a quarter of a million children die in Africa each year as a result of the mosquito-borne disease, including over 10,000 in Kenya.

Ogutu expresses concern for urban residents, saying that the new carrier may feed on poor environmental management systems.

“So the fact that this can survive in urban areas where water is not clean and that can transmit, that’s the worry people are having. For the time being its to monitor and see to what extent we are going to have its spreading and what impact it will be having,” said Ogutu.

Redentho Dabelen is a public officer in the Marsabit County town of Laisamis, where the vector was discovered.

He says experts are going to communities to teach people how to protect themselves from the disease.

“To sensitize them and teach them how to prevent themselves from the vector bites. We are trying to spray the houses,” said Dabelen. “We are trying to tell them about the disease through the community health volunteers and if they get infected they go to the hospital.”

According to the researchers, the population should continue to use malaria control tools such as sleeping under mosquito nets and practicing good environmental management and sanitation.

In 2021, the WHO approved a malaria vaccine for children aged five months to two years that has been shown to reduce child deaths.

Two Russian cosmonauts and an American astronaut will remain aboard the International Space Station for an extra six months because of damage to their Russian spacecraft.

Sergey Prokopyev, Dmitry Petelin and Frank Rubio were set to end their six-month stay aboard the ISS in late March, but the Russian space agency Roscosmos said Tuesday the trio will have to remain on the orbital outpost until September.

The Soyuz MS-22 capsule that carried the crew to the ISS last September has been leaking coolant since mid-December, which both Roscosmos and the U.S. space agency NASA have blamed on a micrometeoroid, or space rock, that struck the capsule.

Russia had planned to send an unmanned Soyuz capsule to the ISS earlier this month to bring the crew home, but the launch of that spacecraft was postponed because a Russian Progress MS-21 cargo ship docked at the station was also leaking coolant. That leak has been blamed by officials on an “external impact.”

Prokopyev, Petelin and Rubio were joined on the ISS in October by four astronauts brought by a SpaceX capsule: two Americans, a Russian and a Japanese. The space station will become even more crowded next week when another four person crew, including an astronaut from the United Arab Emirates, is set to arrive.

Some information for this report came from Reuters and Agence France-Presse.

The U.N. in Malawi has launched an urgent appeal for aid to deal with the impact of a record cholera outbreak that has so far killed nearly 1,450 people and infected 45,000.  

Local health experts say if urgent action isn’t taken to scale up the response, the number of cases could double in the next few months.

The U.N. says the flash appeal seeks to raise $45.3 million to provide life-saving aid to thousands of people in Malawi devastated by the outbreak.

In a statement released Monday, the U.N. said the appeal aims to assist four million people in Malawi, including 56,000 refugees and asylum seekers who are at the highest risk in the outbreak.

The current outbreak started in March last year and has spread to all 29 districts of Malawi.

Rebecca Adda-Dontoh, the U.N. resident coordinator in Malawi, told reporters Monday that more assistance is needed to stop the outbreak.

“So much work has been done but a lot more needs to be done,” she said. “We have focused on health, we have focused on WASH (water, sanitation and hygiene). The two are very important but there are also other sectors like nutrition, protection and even logistics because we need to be able to move supplies from one point to the other.”

Adda-Dontoh said the needed assistance would complement what various donor partners have already contributed.

“The U.N. itself has mobilized already close to $10 million,” she said. “You heard the EU; you heard the U.K. here saying they had already contributed over 500,000 euros for the EU and also over 500,000 pounds for the U.K. Even the government of Malawi is on the ground and already contributed.”   

Local media have reported that Malawi needs an additional $40 million for its national plan on cholera response.

Cases of cholera in Malawi have increased since the beginning of January, worsening the country’s largest outbreak in the past two decades.

Malawian President Lazarus Chakwera said last week, when he launched a national anti-cholera campaign, that the country’s health facilities were recording between 500 to 600 cholera cases every day.

The U.N. said that health experts have warned that Malawi could record between 64,000 and 100,000 more cases of cholera within the next three months unless urgent action is taken to scale up the response.

When COVID-19 hit in 2020, Ghenya Grondin of Waltham, Massachusetts, was a postpartum doula – a person charged with helping young couples navigate the first weeks of their newborn child’s life at home.

Grondin, now aged 44, was infected with SARS-CoV-2 in mid-March of that year – before there were tests, before social distancing or masks, and many months before the medical community recognized long COVID as a complication of COVID-19.

She is part of a community of first-wave long-haulers who faced a new disease without a roadmap or support from the medical establishment.

Three years later, at least 65 million people worldwide are estimated to have long COVID, according to an evidence review published last month in Nature Reviews Microbiology. More than 200 symptoms have been linked to the syndrome – including extreme fatigue, difficulty thinking, headaches, dizziness when standing, sleep problems, chest pain, blood clots, immune dysregulation, and even diabetes.

There are no proven treatments but research is underway.

People infected later in the pandemic had the benefit of vaccination, which “protects at least to some degree” from long COVID, said Dr. Bruce Levy, a Harvard pulmonologist and a co-principal investigator of the National Institute of Health’s $1.15 billion U.S. RECOVER trial, which aims to characterize and find cures for the disease.

“The initial variant of the virus caused a more severe illness than we’re seeing currently in most patients,” he said.

According to the University of Washington’s Institute of Health Metrics and Evaluation, in the first two years of the pandemic women were twice as likely as men to develop long COVID, and 15% of all of those affected at three months continued to experience symptoms beyond 12 months.

An analysis of thousands of health records by the RECOVER trial found that non-Hispanic white women in wealthier areas were more likely than others to have a long COVID diagnosis. Researchers said that likely reflected disparities in access to health care, and suggests that many cases of long COVID among people of color are not being diagnosed.

Grondin grew concerned when she continued to have symptoms three months after her initial infection – but there was no name for it then.

“I just kept saying to my husband, something isn’t right,” she said.

Like her fellow long-haulers, she has experienced a host of symptoms, including fatigue, sleep apnea, pain, cognitive dysfunction, and in her case, a brain aneurysm. She described a frightening moment when she was driving a car with her toddler in the back and had a seizure that left her in the path of oncoming traffic.

She has since been diagnosed with long COVID and can no longer work.

“It just feels like a constant punch in the face,” said Grondin.

Scientists are still working out why some people infected with COVID develop long-term symptoms, but syndromes like this are not new. Other infections such as Lyme disease can result in long-term symptoms, many of which overlap with long COVID.

Leading theories of the root causes of long COVID include the virus or viral proteins remaining in the tissues of some individuals; the infection causing an autoimmune response; or the virus reactivating latent viruses, leading to inflammation that damages tissue.

Kate Porter, 38, of Beverly, Massachusetts, a project manager for a financial services company, believes she was infected on a flight back from Florida in late March of 2020.

She had daily fevers for seven months, muscle weakness, shortness of breath, and excruciating nerve pain.

“I don’t think people realize how brutal physically everything was,” she said. In one of her darker moments, Porter recalled, “I cried on the floor begging for something to take me peacefully. I’ve never been like that.”

Frustrated by the lack of answers from a list of 10 specialists she has seen, Porter has explored alternative medicine. “It has opened me up to other remedies,” she said.

Although her health is much improved now, she still suffers from near daily migraines and neck pain she fears may never go away.

Genie Stevens, 65, a director of climate education, got infected while traveling from her home in Santa Fe to Cape Cod in late March 2020 to visit her mother, and never left. “It completely upended my life,” she said.

She went to an emergency department seeking tests and was told there were none – the typical answer in the spring of 2020, when scientists were scrambling to understand the nature of the virus and tests were being rationed. She was sent home to manage on her own.

A lifelong practitioner of meditation, Stevens took solace there, finding it eased her symptoms.

Confined to her bed that spring, she focused on an ancient crabapple tree outside her room. “I watched every bud unfurl.”

Although largely recovered, Stevens still has flare-ups of brain fog, exhaustion and high-pitched ringing in her ears when she pushes too hard. “This is the astoundingly maddening part of the illness. I feel totally fine, and then bam.”

United Nations members gather Monday in New York to resume efforts to forge a long-awaited and elusive treaty to safeguard the world’s marine biodiversity. 

Nearly two-thirds of the ocean lies outside national boundaries on the high seas where fragmented and unevenly enforced rules seek to minimize human impact. 

The goal of the U.N. meetings, running through March 3, is to produce a unified agreement for the conservation and sustainable use of those vast marine ecosystems. The talks, formally called the Intergovernmental Conference on Marine Biodiversity of Areas Beyond National Jurisdiction, resume negotiations suspended last fall without agreement on a final treaty. 

“The ocean is the life support system of our planet,” said Boris Worm, a marine biologist at Canada’s Dalhousie University. “For the longest time, we did not feel we had a large impact on the high seas. But that notion has changed with expansion of deep-sea fishing, mining, plastic pollution, climate change,” and other human disturbances, he said. 

The U.N. talks will focus on key questions, including: How should the boundaries of marine protected areas be drawn, and by whom? How should institutions assess the environmental impacts of commercial activities, such as shipping and mining? And who has the power to enforce rules? 

“This is our largest global commons,” said Nichola Clark, an oceans expert who follows the negotiations for the nonpartisan Pew Research Center in Washington. “We are optimistic that this upcoming round of negotiations will be the one to get a treaty over the finish line.” 

The aim of the talks is not to designate marine protected areas, but to establish a mechanism for doing so. 

“The goal is to set up a new body that would accept submissions for specific marine protected areas,” Clark said. 

Marine biologist Simon Ingram at the University of Plymouth in England says there’s an urgent need for an accord. 

“It’s a really pressing time for this — especially when you have things like deep-sea mining that could be a real threat to biodiversity before we’ve even been able to survey and understand what lives on the ocean floor,” Ingram said. 

Experts say that a global oceans treaty is needed to enforce the U.N. Biodiversity Conference’s recent pledge to protect 30% of the planet’s oceans, as well as its land, for conservation. 

“We need a legally binding framework that can enable countries to work together to actually achieve these goals they’ve agreed to,” said Jessica Battle, an expert on oceans governance at World Wide Fund for Nature 

U.S. Assistant Secretary of State for Oceans and International Environmental and Scientific Affairs Monica Medina said the treaty is a priority. 

“This agreement seeks to create, for the first time, a coordinated approach to establishing marine protected areas on the high seas,” she said. “It’s time to finish the job.” 

Officials, environmentalists and representatives of global industries that depend on the sea are also watching negotiations closely. 

Gemma Nelson, a lawyer from Samoa and an Ocean Voices fellow at the University of Edinburgh, said that small Pacific and Caribbean island countries were “especially vulnerable to global ocean issues,” such as pollution and climate change, which generally they did not cause nor have the resources to easily address. 

“Getting the traditional knowledge of local people and communities recognized as valid” is also essential to protect both ecosystems and the ways of life of Indigenous groups, she said. 

With nearly half the planet’s surface covered by high seas, the talks are of great importance, said Gladys Martínez de Lemos, executive director of the nonprofit Interamerican Association for Environmental Defense focusing on environmental issues across Latin America. 

“The treaty should be strong and ambitious, having the authority to establish high and fully protected areas in the high seas,” she said. “Half of the world is at stake these weeks at the United Nations.”

The prospect of large-scale mining to extract valuable minerals from the depths of the Pacific Ocean, once a distant vision, has grown more real, raising alarms among the oceans’ most fervent defenders.

“I think this is a real and imminent risk,” Emma Wilson of the Deep Sea Conservation Coalition, an umbrella organization of environmental groups and scientific bodies, told AFP.

“There are plenty of stakeholders that are flagging the significant environmental risks.”

And the long-awaited treaty to protect the high seas, even if it is adopted in negotiations resuming on Monday, is unlikely to alleviate risks anytime soon: it will not take effect immediately and will have to come to terms with the International Seabed Authority (ISA).

That agency, established under the U.N. Convention on the Law of the Sea, has 167 member states.

It has authority over the ocean floors outside of member states’ Exclusive Economic Zones (which extend up to 200 nautical miles, or 370 kilometers, from coastlines).

But conservation groups say the ISA has two glaringly contradictory missions: protecting the sea floors under the high seas while organizing the activities of industries eager to mine untapped resources on the ocean floor.

For now, some 30 research centers and enterprises have been approved to explore — but not exploit — limited areas.

Mining activities are not supposed to begin before negotiators adopt a mining code, already under discussion for nearly a decade.

Making waves

But the small Pacific island nation of Nauru, impatient with the plodding pace of progress, made waves in June 2021 by invoking a clause allowing it to demand relevant rules be adopted within two years.

Once that deadline is reached, the government could request a mining contract for Nori (Nauru Ocean Resources), a subsidiary of Canada’s The Metals Company.

Nauru has offered what it called a “good faith” promise to hold off until after an ISA assembly in July, in hopes it will adopt a mining code.

“The only thing we need is rules and regulations in place so that people are all responsible actors,” Nauru’s ambassador to the ISA Margo Deiye told AFP.

But it is “very unlikely” that a code will be agreed by July, said Pradeep Singh, a sea law expert at the Research Institute for Sustainability, in Potsdam, Germany.

“There’s just too many items on the list that still need to be resolved,” he told AFP. Those items, he said, include the highly contentious issue of how profits from undersea mining would be shared, and how environmental impacts should be measured.

NGOs thus fear that Nori could obtain a mining contract without the protections provided by a mining code.

Conservation groups complain that ISA procedures are “obscure” and its leadership is “pro-extraction.”

The agency’s secretary-general, Michael Lodge, insists that those accusations have “absolutely no substance whatsoever.”

He noted that contracts are awarded by the ISA’s Council, not its secretariat.

“This is the only industry…that has been fully regulated before it starts,” he said, adding that the reason there is no undersea mining “anywhere in the world right now is because of the existence of the ISA.”

Target: 2024

Regardless, The Metals Company is making preparations.

“We’ll be ready, and aim to be in production by the end of 2024,” chief executive Gerard Barron told AFP.

He said the company plans to collect 1.3 million tons of material in its first year and up to 12 million tons by 2028, all “with the lightest set of impacts.”

Barron said tons of polymetallic nodules (rich in minerals such as manganese, nickel, cobalt, copper and rare earths), which had settled to the ocean floor over the centuries, could easily be scraped up.

This would occur in the so-called Clipperton Fracture Zone, where Nori in late 2022 conducted “historic” tests at a depth of four kilometers (2.4 miles).

But Jessica Battle of the WWF conservation group said it is not that simple. Companies might, for example, suck up matter several yards (meters) down, not just from the seabed surface.

“It’s a real problem to open up a new extractive frontier in a place where you know so little, with no regulations,” she told AFP. “It will be a disaster.”

Scientists and advocacy groups say mining could destroy habitats and species, some of them still unknown but possibly crucial to food chains; could disturb the ocean’s capacity to absorb human-emitted carbon dioxide; and could generate noises that might disrupt whales’ ability to communicate.

Moratorium calls

“The deep ocean is the least known part of the ocean,” said deep-sea biologist Lisa Levin of the Scripps Institution of Oceanography. “So change might take place without anybody ever seeing it.”

She has signed a petition calling for a moratorium on mining. Some companies and about a dozen countries support such a call, including France and Chile.

With its slogan, “A battery in a rock,” The Metals Company emphasizes the world’s need for metals used in electric-vehicle batteries; Nauru makes the same case.

But while island nations are among the first to feel the impact of global warming, Nauru says it can’t wait forever for the funds rich countries have promised to help it adapt to those impacts.

“We’re tired of waiting,” said Deiye, the Nauru ambassador.

And Lodge says people should keep the anti-extraction arguments in perspective.

Of the 54 percent of seabeds under ISA jurisdiction, he said, “less than half a percent is under exploration… and of that half a percent, less than one percent is likely ever to be exploited.”

The little-noticed program that led to a Chinese spy balloon drifting across the United States this month has been discussed in China’s state-controlled media for more than a decade in articles extolling its potential military applications.

The reports, dating back to at least 2011, focus on how best to exploit what is known as “near space” – that portion of the atmosphere that is too high for traditional aircraft to fly but too low for a satellite to remain in orbit. Those early articles may offer clues to the capabilities of the balloon shot down by a U.S. jet fighter on Feb. 4.

“In recent years, ‘near space’ has been discussed often in foreign media, with many military commentators pointing out that this is a special sphere that had been neglected by militaries but now has risen to hotspot status,” reads a July 5, 2011, article in the People’s Liberation Army Daily titled Near Space – A Strategic Asset That Ought Not to be Neglected.

The article quoted Zhang Dongjiang, a senior researcher at the Chinese Academy of Military Sciences, discussing the potential applications of flying objects designed for near space.

“This is an area sitting in between ‘air’ and ‘space’ where neither the theory of gravity nor Kepler’s Law is independently applicable, thus limiting the freedom of flight for both aircraft that are designed based on the theory of gravity and spacecraft that follow Kepler’s Law,” Zhang was quoted as saying.

He noted that near space lacks the atmospheric disturbances of aeronautical altitudes, such as turbulence, thunder and lightning, yet is cheaper and easier to reach than the altitudes where satellites can remain in orbit.

“At the same time,” he added, near space is “much higher than ‘sky,’ hence holding superb prospects and potential for intelligence collection, reconnaissance and surveillance, securing communication, as well as air and ground warfare.”

Zhang suggested that near space can be exploited with “high-dynamic” craft that travel faster than the speed of sound, such as hypersonic cruise vehicles and sub-orbital vehicles, which “can arrive at target with high speed, attack with both high speed and precision, [and] can be deployed repeatedly.”

But he said near space also can provide an environment for slower vehicles, which he called “low-dynamic” craft, such as stratospheric airships, high-altitude balloons and solar-powered unmanned vehicles.

These, he said, “are capable of carrying payloads capable of capturing light, infrared rays, multispectral, hyper-spectral, radar, and other info, which can then be used to increase battlefield sensory and knowledge capability, support military operations.”

They also “can carry various payloads aimed at electronic counter-battle, fulfilling the aim of electronic magnetic suppression and electronic magnetic attack on the battlefield, damage and destroy an adversary’s information systems.”

Four years after the PLA Daily article, images were published in the military pages of Global Times, a state-controlled outlet, of two small-scale stratospheric vehicles identified as KF13 and KF16.

The vehicles were developed by the Opto-Electronics Engineering Institute of Beijing Aeronautics and Aerospace University, China’s main aeronautical and aerospace research university, according to an explanatory note published alongside the model shown in the Global Times. The institution is now known as Beihang [Beijing-Aero] University.

The explanatory note said a key feature of the vehicles was their unmanned and remote-control dual capability. Work was being done in Beijing and Shanghai, as well as in Shanxi province, on seeing the vehicles evolve from concept to production, according to the October 2015 article.

Other images of near space objects that surfaced the same month featured variously shaped aircraft whose features and functions included high-functioning surface materials, emergency control mechanisms, precise flight control technology, high-efficiency propeller technology, high-efficiency solar technology and ground operation integration technology.

An image of a blimp-like near space flying object called the Yuan Meng, literally “fulfilling dream,” was also posted to the internet in October 2015. It was described as having a flying altitude of 20-24 kilometers, a flight duration of six months and a payload of 100-300 kilograms.

Rick Fisher, a senior fellow at the International Assessment and Strategy Center in Washington, told VOA that China’s interest in the exploitation of near space actually began long before the PLA Daily article.

“Since the late 1990s, the PLA has been devoting resources for research and development for preparing for combat in ‘near space,’ the zone just below Low Earth Orbit (LEO) that is less expensive to reach than LEO [itself], and offers stealth advantages, especially for hypersonic platforms,” he said in an exchange of emails.

In addition to round balloons such as the one shot down by U.S. aircraft on Feb. 4, he said, “the PLA is also developing much larger blimp or airship stratospheric balloons that have solar powered engines driving large propellers that enable greater maneuverability.”

Fisher said Chinese state-owned conglomerates such as China Aerospace Science and Industry Corporation (CASIC) “have full-fledged near space programs like their Tengyun to produce very high-altitude UAV and hypersonic vehicles” for the purpose of waging combat in near space.

Tengyun literally means “riding above clouds.”

In September 2016, Chinese official media reported that Project Tengyun, initiated by CASIC, was expected to be ready for a test flight in 2030. The so-called “air-spacecraft” is designed to serve as a “new-generation, repeat-use roundtrip flying object between air and space,” a deputy general manager of CASIC told the 2nd Commercial Aeronautical Summit Forum held in Wuhan that month.

Another four projects proposed by CASIC also bore the concept of “cloud” in their names: Feiyun, meaning “flying cloud,” focuses on communication relay; Xingyun, meaning “cloud on the move,” would enable users to send text or audio messages even “at the end of the earth or edge of the sky”; Hongyun, meaning rainbow cloud, would be able to launch 156 satellites in its first stage; and Kuaiyun, meaning “fast cloud,” would be tasked with formulating a near space spheric network.

While China’s openness about its near space ambitions may be debatable, the speed with which it has made advances in related R&D appears to be indisputable.

“Throughout my career that was focused on the PLA, I do not recall anything about the PLA having a balloon program, let alone to have balloons operating over U.S. territory,” U.S. Navy Captain (retired) James Fanell, who retired as [a former] director of intelligence for the U.S. Pacific Fleet in 2015, told VOA in a written interview.

U.S. official now say they are aware of at least 40 incidents, however, in which Chinese surveillance balloons have passed over countries on as many as five continents. Those presumably included an incident last December in which a high-altitude airship was photographed near the northern Philippine Island of Luzon bordering the South China Sea.

“The object would look to be a teardrop-shaped airship with four tail fins. It’s not entirely clear from the images whether it might have a translucent exterior or a metallic-like one,” wrote Joseph Trevithick, deputy editor of The War Zone, a specialized website dedicated to developments in military technology and international security.

“Overall, the apparent airship’s general shape has broad similarities to a number of high-altitude, long-endurance types that Chinese companies are known to have been working on,” he wrote, including “at least two uncrewed solar-powered designs, the Tian Hang and Yuan Meng, with external propulsion and other systems intended primarily for operations at stratospheric altitudes, both of which have reportedly been test flown at least once.”

Fisher said the United States would be well advised to emulate China in enhancing its capabilities in near space.

The American aerospace company Lockheed Martin “tested a technology demonstrator in 2011 [but] there has been no further development of operational stratospheric airships for the U.S.” since then, Fisher said.

“The PLA is correct to invest in stratosphere balloons and airships; the U.S. must do more to develop these assets as well.”
