WASHINGTON — A defunct Russian satellite has broken up into more than 100 pieces of debris in orbit, forcing astronauts on the International Space Station to take shelter for about an hour and adding to the mass of space junk already in orbit, U.S. space agencies said. 

There were no immediate details on what caused the breakup of the RESURS-P1 Russian Earth observation satellite, which Russia declared dead in 2022. 

U.S. Space Command, tracking the debris swarm, said there was no immediate threat to other satellites. 

The event took place about noon EDT (1600 GMT) Wednesday, Space Command said. It occurred in an orbit near the space station, prompting U.S. astronauts on board to shelter in their spacecraft for roughly an hour, NASA’s Space Station office said. 

Russian space agency Roscosmos, which operated the satellite, did not respond to a request for comment or publicly acknowledge the event on its social media channels. 

U.S. Space Command, which has a global network of space-tracking radars, said the satellite immediately created “over 100 pieces of trackable debris.” 

By Thursday afternoon, radars from U.S. space-tracking firm LeoLabs had detected at least 180 pieces, the company said.  

Large debris-generating events in orbit are rare but of increasing concern as space becomes crowded with satellite networks vital to everyday life on Earth, from broadband internet and communications to basic navigation services, as well as satellites no longer in use. 

The satellite’s breakup was at an altitude of roughly 355 km (220 miles) in low-Earth orbit, a popular region where thousands of small to large satellites operate, including SpaceX’s vast Starlink network and China’s station that houses three of its astronauts. 

“Due to the low orbit of this debris cloud, we estimate it’ll be weeks to months before the hazard has passed,” LeoLabs said in a statement to Reuters. 

The some 25,000 pieces of debris bigger than 10 cm (4 inches) in space caused by satellite explosions or collisions have raised concerns about the prospect of a Kessler effect — a phenomenon in which satellite collisions with debris can create a cascading field of more hazardous junk and exponentially increase crash risks. 

Russia sparked strong criticism from the U.S. and other Western countries in 2021 when it struck one of its defunct satellites in orbit with a ground-based anti-satellite (ASAT) missile launched from its Plesetsk rocket site. The blast, testing a weapon system ahead of Moscow’s 2022 invasion of Ukraine, created thousands of pieces of orbital debris. 

In the roughly 88-minute window of RESURS-P1’s initial breakup, the Plesetsk site was one of many locations on Earth it passed over, but there was no immediate indication from airspace or maritime alerts that Russia had launched a missile to strike the satellite, space tracker and Harvard astronomer Jonathan McDowell said. 

“I find it hard to believe they would use such a big satellite as an ASAT target,” McDowell said. “But, with the Russians these days, who knows.” 

He and other analysts speculated the breakup more likely could have been caused by a problem with the satellite, such as leftover fuel onboard causing an explosion. 

What happens to old satellites?  

Dead satellites either remain in orbit until they descend into Earth’s atmosphere for a fiery demise years later, or in widely preferred — but less common — circumstances, they fly to a “graveyard orbit” some 36,000 km (22,400 miles) from Earth to lower the risk of crashing into active satellites. 

Roscosmos decommissioned RESURS-P1 over onboard equipment failures in 2021, announcing the decision the following year. The satellite has since appeared to be lowering its altitude through layers of other active satellites for an eventual atmospheric reentry. 

The six U.S. astronauts currently on the space station were alerted by NASA mission control in Houston late Wednesday evening to execute “safe haven” procedures, where each crew member rushes into the spacecraft they arrived in, in case an emergency departure is required. 

NASA astronauts Butch Wilmore and Suni Williams boarded their Starliner spacecraft, the Boeing-built capsule that has been docked since June 6 in its first crewed test mission on the station. 

Three of the other U.S. astronauts and a Russian cosmonaut went into SpaceX’s Crew Dragon capsule that flew them to the station in March, while the sixth U.S. astronaut joined the two remaining cosmonauts in their Russian Soyuz capsule that ferried them there in September last year. 

The astronauts emerged from their spacecraft roughly an hour later and resumed their normal work on the station, NASA said. 

The prospects of satellite collisions and space warfare have added urgency to calls from space advocates and lawyers to have countries establish an international mechanism of managing space traffic, which does not currently exist.

WASHINGTON — Catastrophic Canadian wildfires last year pumped more heat-trapping carbon dioxide into the air than India did by burning fossil fuels, setting ablaze an area of forest larger than the U.S. state of West Virginia, new research finds.

Scientists at the World Resources Institute and the University of Maryland calculated how devastating the impacts were of the monthslong fires in Canada in 2023 that sullied the air around large parts of the globe. They figured it put 2.98 billion metric tons of heat-trapping carbon dioxide into the air, according to a study update published in Thursday’s Global Change Biology. The update is not peer-reviewed, but the original study was.

The fire spewed nearly four times the carbon emissions as airplanes do in a year, study authors said. It’s about the same amount of carbon dioxide that 647 million cars put in the air in a year, based on U.S. Environmental Protection Agency data.

Forests “remove a lot of carbon from the atmosphere and that gets stored in their branches, their trunks, their leaves and kind of in the ground as well. So, when they burn all the carbon that’s stored within them, [it] gets released back into the atmosphere,” said the study’s lead author, James MacCarthy, a research associate with WRI’s Global Forest Watch.

When and if trees grow back, much of that can be recovered, MacCarthy said, adding, “It definitely does have an impact on the global scale in terms of the amount of emissions that were produced in 2023.”

MacCarthy and colleagues calculated that the forest burned totaled 77,574 square kilometers (29,951 square miles), which is six times more than the average from 2001 to 2022. The wildfires in Canada made up 27% of global tree cover loss last year; usually it’s closer to 6%, MacCarthy’s figures show.

These are far more than regular forest fires, but researchers focused only on tree cover loss, which is a bigger effect, said study co-author Alexandra Tyukavina, a geography professor at the University of Maryland.

Syracuse University geography and environment professor Jacob Bendix, who wasn’t part of the study, said, “The loss of that much forest is a very big deal, and very worrisome.

“Although the forest will eventually grow back and sequester carbon in doing so, that is a process that will take decades at a minimum, so that there is a quite substantial lag between addition of atmospheric carbon due to wildfire and the eventual removal of at least some of it by the regrowing forest,” he said.

“So, over the course of those decades, the net impact of the fires is a contribution to climate warming.”

It’s more than just adding to heat-trapping gases and losing forests; there were health consequences as well, Tyukavina said.

“Because of these catastrophic fires, air quality in populated areas and cities was affected last year,” she said, mentioning New York City’s smog-choked summer. More than 200 communities with about 232,000 residents had to be evacuated, according to another not-yet-published or peer-reviewed study by Canadian forest and fire experts.

One of the authors of the Canadian study, fire expert Mike Flannigan at Thompson Rivers University in Kamloops, British Columbia, puts the acreage burned at twice what MacCarthy and Tyukavina do.

“The 2023 fire season in Canada was [an] exceptional year in any time period,” Flannigan, who wasn’t part of the WRI study, said in an email. “I expect more fire in our future, but years like 2023 will be rare.”

Flannigan, Bendix, Tyukavina and MacCarthy all said climate change played a role in Canada’s big burn. A warmer world means a longer fire season, more lightning-caused fires and especially drier wood and brush to catch fire “associated with increased temperature,” Flannigan wrote.

The average May-to-October temperature in Canada last year was almost 2.2 degrees Celsius warmer than normal, his study found. Some parts of Canada were 8 to 10 degrees Celsius hotter than average in May and June, MaCarthy said.

There’s short-term variability within trends, so it’s hard to blame one specific year and area on climate change, and geographic factors play a role, Bendix said in an email, but still, “there is no doubt that climate change is the principal driver of the global increases in wildfire.”

With the world warming from climate change, Tyukavina said, “The catastrophic years are probably going to be happening more often, and we are going to see those spikier years more often.”

Jakarta, Indonesia — Indonesia aims to launch 19 satellites into low-Earth orbit next year, part of an ambitious plan to move the country into the forefront of the world’s growing space industry and reduce its reliance on other countries for its satellite data.

The broader program, known as the 2045 space map, is set to begin next year. Officials hope to boost Indonesia’s economy and drive foreign direct investment by leveraging its unique geography as a near-equatorial, fuel-efficient launch point for space travel and research.

While the satellite launches would support key economic sectors such as agriculture and mining with remote-sensing technology to track weather patterns, mining emissions and mineral-rich areas, the longer-term plan includes development of a leading-edge spaceport to reduce reliance on foreign launch sites.

But according to officials at BRIN, Indonesia’s National Research and Innovation Agency, there’s still no confirmation of which company or government agencies would be responsible for the spate of launches planned for 2025.

“The main constraint was the government’s financial planning and budget cuts. We also couldn’t clinch foreign investment partners to join in developing the spaceport because it is high technology and high cost,” said BRIN researcher Thomas Djamalludin.

Starlink, SpaceX and Elon Musk

Jakarta has relied on Elon Musk’s SpaceX for launching its satellites from Cape Canaveral, Florida, since 2019, and the billionaire entrepreneur last month launched a Starlink internet services satellite directly from Bali.

Indonesian President Joko Widodo has repeatedly invited Musk to use the Papuan province island of Biak as a primary Starlink launch site, which has drawn outrage from locals who say developing the island as a spaceport will devastate its fragile ecology.

Although Biak has an airstrip, military base, deep-water seaport and ground stations, the 500 hectares (1.9 square miles) of government-owned land suitable for the spaceport would require foreign investment to cover the preliminary $613 million required to build the initial phase of the project. The total cost is dependent on what additional facilities investors want to build at the space port.

Luhut Pandjaitan, Indonesia’s coordinating minister for maritime affairs and investment, said that Starlink is mulling the offer but that there are no immediate plans for collaboration.

According to Djamalludin of BRIN, China, which has dominated Indonesia’s 5G market and is on track to be the nation’s largest foreign investor, had expressed interest. However, a catastrophic April 2020 rocket launch that destroyed Indonesia’s $220 million Nusantara-2 satellite has complicated Jakarta’s relationship with China’s state-owned China Great Wall Industry Corporation.

Beijing has since dialed back its financial interests, declaring the Biak location too distant, while Jakarta has doubled down on wooing SpaceX for the upcoming launches, deeming the company more reliable, offering more time slots and cheaper reusable rockets.

Indonesia’s director of investment promotion at the Investment Coordinating Board, Saribua Siahaan, told VOA that Jakarta continues offering financial incentives, along with an easy investment permitting process for public-private partnerships.

No takers in 2023

As recently as 2023, BRIN officials promoted their spaceport plans at the G20 Space Economy Leaders’ Meeting and Asia-Pacific Regional Space Agency Forum. China, Russia, Japan, South Korea and India were invited as potential partners, but none signed on.

“Despite the 2013 Space Law having been in effect for nearly a decade, [Indonesia’s] government has yet to finalize implementing regulations for commercialization of space and spaceport development,” said Indonesian space-law scholars Ridha Aditya Nugraha and Yaries Mahardika Putro in a recent Jakarta Post op-ed.

Indonesia was the first country in ASEAN to enforce national space legislation. The 2013 Space law provides a legal framework regarding outer space, and it lays the foundation for space industry growth.

Foreign direct investment in space activities brings legal certainty that can attract investors. In the past decade, though, implementation of regulations has not occurred and that has made it difficult for the related ministeries to make Indonesia a space-faring country.

“This must be resolved immediately if Indonesia is serious about making outer space a revenue center and the driver of the economy in the future,” the op-ed said.

WASHINGTON — The Supreme Court is putting the Environmental Protection Agency’s air pollution-fighting “good neighbor” plan on hold while legal challenges continue, the conservative-led court’s latest blow to federal regulations.

The justices in a 5-4 vote on Thursday rejected arguments by the Biden administration and Democratic-controlled states that the plan was cutting air pollution and saving lives in 11 states where it was being enforced and that the high court’s intervention was unwarranted.

The rule is intended to restrict smokestack emissions from power plants and other industrial sources that burden downwind areas with smog-causing pollution. It will remain on hold while the federal appeals court in Washington considers a challenge to the plan from industry and Republican-led states.

The Supreme Court, with a 6-3 conservative majority, has increasingly reined in the powers of federal agencies, including the EPA, in recent years. The justices have restricted the EPA’s authority to fight air and water pollution — including a landmark 2022 ruling that limited the EPA’s authority to regulate carbon dioxide emissions from power plants that contribute to global warming. The court also shot down a vaccine mandate and blocked President Joe Biden’s student loan forgiveness program.

The court is currently weighing whether to overturn its 40-year-old Chevron decision, which has been the basis for upholding a wide range of regulations on public health, workplace safety and consumer protections.

Three energy-producing states — Ohio, Indiana and West Virginia — have challenged the air pollution rule, along with the steel industry and other groups, calling it costly and ineffective. They had asked the high court to put it on hold while their challenge makes it way through the courts.

The challengers pointed to decisions in courts around the country that have paused the rule in a dozen states, arguing that those decisions have undermined the EPA’s aim of providing a national solution to the problem of ozone pollution because the agency relied on the assumption that all 23 states targeted by the rule would participate.

The issue came to the court on an emergency basis, which almost always results in an order from the court without arguments before the justices.

But not this time. The court heard arguments in late February, when a majority of the court seemed skeptical of arguments from the administration and New York, representing Democratic states, that the “good neighbor” rule was important to protect downwind states that receive unwanted air pollution from other states.

The EPA has said power plant emissions dropped by 18% last year in the 10 states where it has been allowed to enforce its rule, which was finalized a year ago. Those states are Illinois, Indiana, Maryland, Michigan, New Jersey, New York, Ohio, Pennsylvania, Virginia and Wisconsin. In California, limits on emissions from industrial sources other than power plants are supposed to take effect in 2026.

The rule is on hold in another dozen states because of separate legal challenges. Those states are Alabama, Arkansas, Kentucky, Louisiana, Minnesota, Mississippi, Missouri, Nevada, Oklahoma, Texas, Utah and West Virginia.

States that contribute to ground-level ozone, or smog, are required to submit plans ensuring that coal-fired power plants and other industrial sites don’t add significantly to air pollution in other states. In cases in which a state has not submitted a “good neighbor” plan — or in which the EPA disapproves a state plan — the federal plan was supposed to ensure that downwind states are protected.

Ground-level ozone, which forms when industrial pollutants chemically react in the presence of sunlight, can cause respiratory problems, including asthma and chronic bronchitis. People with compromised immune systems, the elderly and children playing outdoors are particularly vulnerable.

SAN DIEGO — A pair of giant pandas are on their way from China to the U.S., where they will be cared for at the San Diego Zoo as part of an ongoing conservation partnership between the two nations, officials said Wednesday.

Officials with the San Diego Zoo Wildlife Alliance were on hand in China for a farewell ceremony commemorating the departure of the giant pandas, Yun Chuan and Xin Bao.

The celebration included cultural performances, video salutations from Chinese and American students and a gift exchange among conservation partners, the zoo said in a statement. After the ceremony, the giant pandas began their trip to Southern California.

“This farewell celebrates their journey and underscores a collaboration between the United States and China on vital conservation efforts,” Paul Baribault, the wildlife alliance president, said in a statement. “Our long-standing partnership with China Wildlife Conservation Association has been instrumental in advancing giant panda conservation, and we look forward to continuing our work together to ensure the survival and thriving of this iconic species.”

It could be several weeks before the giant pandas will be viewable to the public in San Diego, officials said.

Yun Chuan, a mild-mannered male who’s nearly 5 years old, has connections to California, the wildlife alliance said previously. His mother, Zhen Zhen, was born at the San Diego Zoo in 2007 to parents Bai Yun and Gao Gao.

Xin Bao is a nearly 4-year-old female described as “a gentle and witty introvert with a sweet round face and big ears.”

The San Diego Zoo Wildlife Alliance has a nearly 30-year partnership with leading conservation institutions in China focused on protecting and recovering giant pandas and the bamboo forests they depend on.
