NASA on Tuesday delayed putting astronauts back on the moon until 2025 at the earliest, missing the deadline set by the Trump administration.

The space agency had been aiming for 2024 for the first moon landing by astronauts in a half-century.

In announcing the delay, NASA Administrator Bill Nelson said Congress did not provide enough money to develop a landing system for its Artemis moon program and more money is needed for its Orion capsule. In addition, a legal challenge by Jeff Bezos’ rocket company, Blue Origin, stalled work for months on the Starship lunar landing system under development by Elon Musk’s SpaceX.

Officials said technology for new spacesuits also needs to ramp up, before astronauts can return to the moon.

NASA is still targeting next February for the first test flight of its moon rocket, the Space Launch System, or SLS, with an Orion capsule. No one will be on board. Instead, astronauts will strap in for the second Artemis flight, flying beyond the moon but not landing in 2024, a year later than planned. That would bump the moon landing to at least 2025, according to Nelson.

“The human landing system is a crucial part of our work to get the first woman and the first person of color to the lunar surface, and we are getting geared up to go,” Nelson told reporters. “NASA is committed to help restore America’s standing in the world.”

Nelson made note of China’s ambitious and aggressive space program, and warned it could overtake the U.S. in lunar exploration.

NASA’s last moon landing by astronauts occurred during Apollo 17 in 1972. Altogether, 12 men explored the lunar surface.

During a National Space Council meeting in 2019, Vice President Mike Pence called for landing astronauts on the moon within five years “by any means necessary.” NASA had been shooting for a lunar landing in 2028, and pushing it up by four years was considered at the time exceedingly ambitious, if not improbable.

Congress will need to increase funding, beginning with the 2023 budget, in order for NASA to have private companies competing for the planned 10 or more moon landings by astronauts, Nelson said.

The space agency also is requesting a bigger budget for its Orion capsules, from $6.7 billion to $9.3 billion, citing delays during the coronavirus pandemic and storm damage to NASA’s Michoud Assembly Facility in New Orleans, the main manufacturing site for SLS and Orion. Development costs for the rocket through the first Artemis flight next year stand at $11 billion.

Vice President Kamala Harris will convene her first National Space Council meeting, as its chair, on December 1. Nelson said he updated her on the latest schedule and costs during their visit to Maryland’s Goddard Space Flight Center on Friday.

Former U.S. President Barack Obama told the U.N. Climate Change Conference in Glasgow, Scotland, on Monday that world leaders at the summit “have not done nearly enough” to address the climate crisis.

Speaking during the second full week of the talks, known as COP26, Obama said that most nations failed to meet the commitments made in the 2015 Paris climate conference agreement and that the world is nowhere near where it needs to be in confronting climate change.

He said it was “particularly discouraging” that the leaders of China and Russia — two of the largest emitters — declined to attend the Glasgow conference, saying both nations have demonstrated what “appears to be a dangerous lack of urgency” on climate change.

China is the world’s biggest carbon emitter. In a statement to the conference last week, Chinese President Xi Jinping called on other nations to “step up cooperation” and act on climate targets. Xi, however, offered no new commitments.

Obama said advanced economies such as the United States and Europe need to lead on this issue, but so do China, Russia and India. “We can’t afford anybody on the sidelines,” he said.

He also argued it was essential to listen to people who objected to swift action on climate change.

“We actually have to listen to their objections and understand the reluctance of some ordinary people to see their countries move too fast on climate change. We have to understand their realities and work with them so that serious action on climate change doesn’t adversely impact them,” he said.

He added, “We’ve got to persuade the guy who has got to drive to his factory job every day, can’t afford a Tesla, and might not be able to pay the rent or feed his family if gas prices go up.”

The United States is the second-biggest greenhouse gas emitter after China.

Call to protest

More than 100,000 climate-action activists from across the world took to the streets of Glasgow on Saturday to express their frustration at what’s been agreed to so far at the COP26 climate talks.

As far as they’re concerned, the new pledges made during the summit — to cut carbon and methane emissions, end deforestation, phase out coal, and provide more financing for poorer countries most vulnerable to extreme weather — are just “eye candy,” falling far short of what’s needed to curb global warming.

Teenage climate activist Greta Thunberg, who was among the protesters, has described the two-week summit as more “blah blah blah” and called it a “failure.” She told clamorous youth protesters outside the venue that the conference has turned into “a global north greenwash festival.”

Others worry, though, that in the rush to make climate action pledges, Western governments may be going too fast with decarbonizing and risk losing the support of their own populations by failing to take into account the economic impact of the monumental shifts envisaged.

Opinion polls suggest that across the globe, overwhelming majorities of people see climate change as an emergency requiring dramatic action. But some polls in recent weeks have also suggested that when people are told what the costs to them may be to curb global warming, they are reluctant to shoulder the financial burden.

A survey in Britain published Sunday suggested that less than half of the British people were willing to pay thousands of pounds to make their homes greener to help meet net-zero emission goals outlined by Prime Minister Boris Johnson.

Those polled were asked their opinions on green policies to slash emissions both before and after hearing about the estimated upfront costs of insulating their homes and switching from natural gas boilers for heating to heat pumps. In the survey conducted for British think tank Onward by pollster JL Partners, 50% backed the idea of better insulation for homes, double glazing and switching to heat pumps. But when they were provided with the estimated cost of $11,000 per household, support trailed away, with just 26% agreeing.

“Millions of voters, broadly supportive of the ‘cleaner earth’ agenda, are wondering how much of the burden of transitioning to a low-carbon, low-emission economy will fall on them, when they’re already struggling to make ends meet,” economist and newspaper columnist Liam Halligan wrote Monday in The Telegraph.

Financing the switch

Key themes at the summit have included how to fund the transition away from fossil fuel dependency to renewable, sustainable energy and how to finance projects to make countries more resilient to extreme weather. The discussion about costs and how to share them between governments (via taxation), consumers, households and the private sector has also been featured.

Last week, major banks, investors and insurers pledged trillions in green funding in a coordinated commitment to incorporate carbon emissions into their investment and lending decisions.

The United Nations’ Glasgow Financial Alliance for Net Zero, made up of more than 450 financial institutions across 45 countries and managing assets valued at $130 trillion, has committed to its program to cut carbon emissions and fund investments needed for new greener technologies.

Unveiled last week by U.N. climate envoy Mark Carney, the funding can take the form of bank loans and investments by venture capitalists, private-equity firms, mutual funds, endowments, and other big investors that buy stocks and bonds. They would still earn profits while shifting funds toward investments that help reduce carbon emissions.

“These seemingly arcane but essential changes to the plumbing of finance can move and are moving climate changes from the fringes to the forefront and transforming the financial system in the process,” said Carney, a former head of the central banks of England and Canada. “The architecture of the global financial system has been transformed to deliver net zero,” Carney said.

“The gap between what governments have and what the world needs is large” to finance a global energy transition and reach the goal of net-zero emissions by 2050, U.S. Treasury Secretary Janet Yellen said in Glasgow after the announcement of the finance measures. “And the private sector needs to play a bigger role.”

Climate activists have decried the pledge, saying it is just another big promise that won’t be observed.

“Global leaders can no longer trust financial institutions to regulate themselves,” Veronica Oakeshott of Global Witness, an international nongovernmental organization, said in a statement.

Some industry analysts and economists say that the private sector plans are far from concrete, and that significant problems remain on how to measure the carbon footprint of investment portfolios and align those measurements across international financial markets. Of particular concern is how to verify the accuracy of what banks and investors report.

Others worry that financial firms are there to maximize profits for clients and shareholders and that they risk losing customers or breaching their fiduciary obligations if they fail to maintain good returns. It remains unclear at this stage how profitable green investments will be.

There are also worries that the fossil fuel sector will see further divestments by lenders and investors eager to reduce their carbon footprint, which will boost energy costs for consumers as global demand for natural gas and oil continues to rise. Fossil fuel investments are already insufficient to meet future energy demands.

That, in turn, has contributed to the current global energy crunch and record-high energy prices for households and businesses, say industry commentators.

Former U.S. President Barack Obama told the U.N. Climate Change Conference in Glasgow on Monday that most nations failed to meet their commitments made in the 2015 Paris Climate Conference agreement and the world is nowhere near where it needs to be in confronting climate change.

Speaking during the second full week of the talks — known as COP26 — Obama said that while the Paris conference and subsequent agreement showed what is possible and created a framework from which to address the challenges of the climate crisis, most nations failed to be as ambitious as they needed to be.

“The escalation, the ratcheting up of ambition that we anticipated in Paris six years ago has not been uniformly realized,” Obama said. He called it “particularly discouraging” that the leaders of China and Russia — two of the largest emitters — declined to even attend the conference, and both nations have demonstrated what he said “appears to be a dangerous lack of urgency” on climate change.

China is the world’s biggest carbon emitter. Its president, Xi Jinping, last week called on other nations to “step up cooperation” and act on climate targets. Xi, however, offered no new commitments. The comments came in a statement to the conference.

Obama said advanced economies like the United States and Europe need to be leading on this issue, but so do China, Russia and India. He said, “We can’t afford anybody on the sidelines.”

Addressing young people, Obama encouraged them to “vote like your life depends on it, because it does.” Obama said he understood their cynicism about politics, but that governments around the world will not act unless they feel pressure from voters.

The 26th U.N. climate conference — or Conference of the Parties, or COP — is Obama’s first since he helped deliver the 2015 Paris climate accord, when nations committed to cutting fossil fuel and agricultural emissions fast enough to keep the Earth’s warming below catastrophic levels.

Climate summits since then have been less conclusive, especially as the U.S. under President Donald Trump dropped out of the Paris accord. President Joe Biden has since rejoined. Last week, Biden announced ambitious change commitments as he attended the Glasgow conference. The U.S. is the second biggest greenhouse gas emitter after China.

High wind off the Florida coast have prompted SpaceX to delay the return of four space station astronauts who have been in orbit since spring.

The U.S., French and Japanese astronauts were supposed to leave the International Space Station on Sunday, with their capsule splashing down in the Gulf of Mexico on Monday morning. But with gusts exceeding safety limits, SpaceX bumped the departure to Monday afternoon, with a nighttime return to conclude their six-month mission.

The good news is that their trip home will now last eight hours, less than half as long as before. The toilet in their capsule is broken, and so the four will need to rely on diapers while flying home.

SpaceX still is aiming for a Wednesday night launch, at the earliest, of their replacements. This flight also has been delayed by bad weather, as well as an astronaut’s undisclosed medical issue. The issue, described as minor, should be resolved by launch time, officials said.

Last week, SpaceX and NASA flipped the order of the launch and landing because of the deteriorating weather and the looming deadline to get the capsule back from the space station. SpaceX capsules are certified for a maximum 210 days in orbit, and the one there now is approaching 200 days.

Poland’s Health Ministry issued instructions Sunday to doctors confirming that it is legal to terminate a pregnancy when the woman’s health or life is in danger, a directive that comes amid apparent confusion over a new restriction to the country’s abortion law.

The document addressed to obstetricians comes in reaction to the hospital death of a 30-year-old mother whose pregnancy was in its 22nd week. The woman died in September but her death became widely known this month. Doctors at the hospital in Pszczyna, in southern Poland, held off terminating her pregnancy despite the fact that her fetus lacked enough amniotic fluid to survive, her family and a lawyer say.

The doctors have been suspended and prosecutors are investigating.

Angered Poles held massive nationwide protests over the weekend, blaming the woman’s death on Poland’s restrictive abortion law. Women’s rights activists say it has a chilling effect on doctors in this predominantly Roman Catholic nation.

The ministry stressed it is in line with the law to terminate a pregnancy when the woman’s health is in danger, even more so in case of threat to her life. It included guidance in case of premature loss of the amniotic fluid.

“It should be clearly stressed that doctors must not be afraid to take evident decisions. stemming from their experience and the available medical knowledge,” the ministry said.

Until a year ago, women in Poland could have abortions in three cases: if the pregnancy resulted from a crime like rape, if the woman’s health or life was at risk, or in the case of irreparable defects of the fetus. That last possibility was eliminated a year ago, when the Constitutional Tribunal ruled it went against Poland’s law.

When a rotten egg smell rises from the mangrove swamps of southeast Mexico, something is going well. It means that this key coastal habitat for blunting hurricane impacts has recovered and is capturing carbon dioxide — the main ingredient of global warming.

While world leaders seek ways to stop the climate crisis at a United Nations conference in Scotland this month, one front in the battle to save the planet’s mangroves is thousands of kilometers away on Mexico’s Yucatan Peninsula.

Decades ago, mangroves lined these shores, but today there are only thin green bands of trees beside the sea, interrupted by urbanized areas and reddish segments killed by too much salt and by dead branches poking from the water.

A few dozen fishermen and women villagers have made building on what’s left of the mangroves part of their lives. Their work is supported by academics and donations to environmental groups, and government funds help train villagers to organize their efforts.

The first time they came to the swamp for seasonal restoration work was more than a decade ago with Jorge Alfredo Herrera, a researcher at the Center for Research and Advanced Studies of the Mexican Polytechnic Institute in Yucatan. He told them the mangroves needed a network of interlaced canals where fresh and salt water would mingle.

To dig them was a hard work and paid only $4 a day. Men from Chelem, a fishing village of Progreso, turned down the job but a group of women took it on, believing they could accomplish a lot with little money.

Recently, after an intense rainy season, the women worked to finish the second part of the restoration process: planting young mangroves in a swamp near this port city. Under the sun, they chuckled, remembering the time they encountered a crocodile and barely managed to run away.

Then they placed 20-inch mangrove seedlings into mounds of mud held together by mesh, creating tiny islands about a yard (meter) square.

“The happiest day is when our plants take,” said 41-year-old Keila Vázquez, leader of the women who now are paid $15 a day and take pride in putting their “grain of sand” into the planet’s well-being. “They are like our children.”

GLOBAL THREAT TO MANGROVES

This mangrove restoration effort is similar to others around the globe, as scientists and community groups increasingly recognize the need to protect and bring back the forests to store carbon and buffer coastlines from climate-driven extreme weather, including more intense hurricanes and storm surges. Other restorations are underway in Indonesia, which contains the world’s largest tracts of mangrove habitat, Colombia and elsewhere.

“Mangroves represent a very important ecosystem to fight climate change,” said Octavio Aburto, a marine biologist at Scripps Institution of Oceanography in San Diego, California.

While the tropical trees only grow on less than 1% of the Earth’s land, he said, “on a per-hectare basis, mangroves are the ecosystem that sequesters the most carbon … They can bury around five times more carbon in the sediment than a tropical rain forest.”

Yet around the globe, mangroves are threatened.

From 1980 to 2005, 20% to 35% of the world’s mangrove forests were lost, according to the U.N. Food and Agriculture Organization.

From 2000 to 2016, the rate of loss declined as governments and environmental groups spotlighted the problem, but destruction continued — and about 2% of the world’s remaining mangrove forests disappeared, according to NASA satellite imagery.

In Mexico, as in much of the world, the largest threat to mangroves is development. The region near Cancun lost most of its historic mangroves to highways and hotels starting in the 1980s.

Tracts of mangroves on the country’s southern Pacific coast also have been cleared to make room for shrimp farming, while oil exploration and drilling in shallow waters off the Gulf of Mexico threatens mangroves there, said Aburto.

Mexico began to protect some of its mangroves only after the excessive tourism development of the 1980s. And although Mexico took steps to establish a climate action plan in 1998 and was one of the first developing countries to make voluntary commitments under the Paris Climate Accord, its commitment to the environment began to backslide in 2015, said Julia Carabias, a professor on the science faculty at the National Autonomous University of Mexico.

In the past six years, Mexico has cut resources for environmental conservation by 60%, according to Carabias.

And that, combined with increasing government support of fossil fuel energy and ongoing infrastructure and tourist projects in the region, is sounding alarms.

Despite the country’s monitoring system, local researchers say that for every hectare (2.5 acres) of mangrove restored in southeast Mexico, 10 hectares are degraded or lost.

EFFORTS TO SAVE SWAMPS

The halting efforts in Mexico to protect and restore mangroves, even as more are lost, mirror situations elsewhere. The U.N. Food and Agriculture Agency estimated in 2007 that 40% of Indonesia’s mangroves had been cut down for aquaculture projects and coastal development in the previous three decades.

But there have been restoration efforts as well.

In 2020, the Indonesia government set an ambitious target of planting mangroves on 600,000 hectares (1.5 million acres) of degrading coastline by 2024. Key ministries are involved in restoration efforts that include community outreach and education.

Yet there have been some setbacks. Precise mapping and data on mangroves is hard to come by, making it difficult for agencies to know where to concentrate. Newly planted mangroves have been swept out to sea by strong tides and waves. Community outreach and education have been slowed by the COVID-19 pandemic.

In Mexico, successes exist, even if they are slow in coming.

Manuel González, a 57-year-old fisherman known as Bechá, proudly shows off recovering mangroves in the seaside community of Dzilam de Bravo, about 60 miles (97 kilometers) east of Progreso. He walks through mud, avoiding the interlaced mangrove roots that burrow into it. Some trees are already 30 feet (9 meters) tall.

In 2002, Hurricane Isidoro devastated this area, but after a decade of work, 297 acres have been restored. The fisherman says that now storms don’t hit the community as hard. And the fish, migratory birds, deer, crocodiles and even jaguars have returned.

But the mangroves face a new risk, as stumps scattered among the trees attest.

“In 10 years, you have a very nice mangrove for someone with a chainsaw to come and take it,” González said. “That’s something that hurts me a lot.”

Cutting mangroves has been a crime since 2005, but González says authorities shut down and fine projects, only to have them later reopen.

The Yucatan state government said it is aware of complaints of illegal logging yet the harvest has only grown.

While more funds are needed for protection and restoration, some communities prefer to think about how to make conservation a profitable activity.

José Inés Loría, head of operations at San Crisanto, an old salt harvesting community of about 500 between Progreso and Dzilam, thinks the way to make the local mangrove part “of the community’s business model” is using the new financial tools such as blue carbon credits.

Those instruments, already in use in Colombia and other countries, allow polluting businesses to compensate for emissions by paying others to store or sequester greenhouse gases.

Some in Mexico say credits are still not well regulated in the country and could invite fraud and scams. But Loria defends them. “If conservation doesn’t mean improving the quality of life of a community, it doesn’t work.”
