Private Japanese lunar lander heads toward a touchdown in the moon's far north

Independent2 days ago

A private lunar lander from Japan is closing in on the moon, aiming for a touchdown in the unexplored far north with a mini rover.
The moon landing attempt by Tokyo-based company ispace on Friday Japan time is the latest entry in the rapidly expanding commercial lunar rush.
The encore comes two years after the company's first moonshot ended in a crash landing, giving rise to the name Resilience for its successor lander. Resilience holds a rover with a shovel to gather lunar dirt as well as a Swedish artist's toy-size red house that will be lowered onto the moon's dusty surface.
Long the province of governments, the moon became a target of private outfits in 2019, with more flops than wins along the way.
Launched in January from Florida on a long, roundabout journey, Resilience entered lunar orbit last month. It shared a SpaceX ride with Firefly Aerospace's Blue Ghost, which reached the moon faster and became the first private entity to successfully land there in March.
Another U.S. company, Intuitive Machines, arrived at the moon a few days after Firefly. But the tall, spindly lander face-planted in a crater near the moon's south pole and was declared dead within hours.
Resilience is targeting the top of the moon, a less forbidding place than the shadowy bottom. The ispace team chose a flat area with few boulders in Mare Frigoris or Sea of Cold, a long and narrow region full of craters and ancient lava flows that stretches across the near side's northern tier.
Once settled with power and communication flowing, the 7.5-foot (2.3-meter) Resilience will lower the piggybacking rover onto the lunar surface.
Made of carbon fiber-reinforced plastic with four wheels, ispace's European-built rover — named Tenacious — sports a high-definition camera to scout out the area and a shovel to scoop up some lunar dirt for NASA.
The rover, weighing just 11 pounds (5 kilograms), will stick close to the lander, going in circles at a speed of less than one inch (a couple centimeters) per second.
Besides science and tech experiments, there's an artistic touch.
The rover holds a tiny, Swedish-style red cottage with white trim and a green door, dubbed the Moonhouse by creator Mikael Genberg, for placement on the lunar surface.
Takeshi Hakamada, CEO and founder of ispace, considers the latest moonshot 'merely a steppingstone,' with its next, much bigger lander launching by 2027 with NASA involvement, and even more to follow.
'We're not trying to corner the market. We're trying to build the market,' Jeremy Fix, chief engineer for ispace's U.S. subsidiary, said at a conference last month. 'It's a huge market, a huge potential."
Fix noted that ispace, like other businesses, does not have 'infinite funds' and cannot afford repeated failures. While not divulging the cost of the current mission, company officials said it's less than the first one which exceeded $100 million.
Two other U.S. companies are aiming for moon landings by year's end: Jeff Bezos' Blue Origin and Astrobotic Technology. Astrobotic's first lunar lander missed the moon altogether in 2024 and came crashing back through Earth's atmosphere.
For decades, governments competed to get to the moon. Only five countries have pulled off successful robotic lunar landings: Russia, the U.S., China, India and Japan. Of those, only the U.S. has landed people on the moon: 12 NASA astronauts from 1969 through 1972.
NASA expects to send four astronauts around the moon next year. That would be followed a year or more later by the first lunar landing by a crew in more than a half-century, with SpaceX's Starship providing the lift from lunar orbit all the way down to the surface. China also has moon landing plans for its own astronauts by 2030.

How groundwater pumping is causing cities to sink at 'worrying speed'

Cities around the world are sinking at 'worrying speed' Animation enabled Twenty-two years ago, when Erna stood outside her house, 'the windows were as high as my chest'. Now they're knee-height. As their home has sunk, she and her family have had to cope with frequent flooding. In the most extreme cases 'we used canoes - the water kept coming in and swamped the ground floor', she says. Erna lives in the Indonesian capital Jakarta - one of the fastest-sinking cities in the world. Her home is in one of the worst-affected areas, the north of the city, and is now much lower than the road. The 37-year-old grew up here and remembers playing in nearby streets and praying in the mosque - that is now long gone, permanently underwater, as is the old port. The walls of her home, built in the 1970s, are cracked, and you can see where thick layers of concrete have been added to the floor to try to restore it to ground level - about 10 times since it was built, and a metre thick in some places. The house is still subsiding, and Erna can't afford to move. Erna and her mother, Soni, have had to raise the floors in their home many times This is one of dozens of coastal regions that are sinking at a worrying speed, according to a study by Nanyang Technological University (NTU) in Singapore. The team studied subsidence in and around 48 coastal cities in Asia, Africa, Europe and the Americas. These are places that are particularly vulnerable to a combination of rising sea levels, which are mainly driven by climate change, and sinking land. Based on the study and population data from the United Nations, the BBC estimates that nearly 76 million people live in parts of these cities that subsided, on average, at least 1cm per year between 2014 and 2020. The impact on their lives can be huge - for example in Tianjin in north-east China, 3,000 people were evacuated from high-rise apartment buildings in 2023, after subsidence left large cracks in nearby streets. All 48 urban areas in the NTU study are shown in this globe. The most extreme cases of subsidence were seen in Tianjin, which has undergone rapid industrial and infrastructural development this century. The worst-hit parts of the city sank up to 18.7cm per year between 2014 and 2020. Select a city below to see how much it is sinking by. A map will display the most subsiding areas in that city in green, with details of factors contributing to subsidence. The subsidence rate is measured from a reference point in each city, which scientists assume is more stable than others - you can read more on the methodology at the end of this article.

But 'one of the most common causes is groundwater extraction', explains the lead researcher on the NTU study, Cheryl Tay. It has had a major impact in half of the 48 coastal cities identified in the study. Groundwater is found beneath the Earth's surface in cracks and spaces in sand, soil and rock. It makes up about half of the water used for domestic purposes - including drinking - around the world. It's also essential for irrigating crops. But as cities grow, freshwater supplies come under strain. Households and industries in some places drill their own wells or boreholes and extract too much - as in Jakarta. Extracting excessive amounts of water in this way over extended periods of time compresses the soil, eventually causing the surface - and everything built on it - to sink or subside. 'A lot of the sinking cities are in Asia or South-East Asia,' says Ms Tay. 'That is likely because the demand for water is much higher there with very fast-growing populations and a lot of development. 'That could lead to higher rates of groundwater extraction and then this could snowball… This means that flooding will be more frequent, intense, and prolonged in the future,' she adds, explaining there could also be 'salt water intrusion that can affect agricultural land and the quality of drinking water'. Some types of ground are affected more than others and Ms Tay believes the risks are especially acute for the many coastal cities built on low-lying deltas - where rivers divide before flowing into the sea. This includes places such as Jakarta, Bangkok, Ho Chi Minh City, and Shanghai. Almost half of Jakarta now sits below sea level. Its location on swampy land where 13 rivers flow into the ocean makes it particularly vulnerable. The combination of land sinking and sea levels rising accelerates the 'relative sea level rise', says Ms Tay. 'There are two components: the land moving down and the water moving up.' Flooding in Jakarta leaves residential and business districts underwater Indonesia's meteorological agency has said that 'the flood cycle, which used to occur every five years, could become more frequent' in Jakarta as 'the overall trend of extreme rainfall is increasing in Indonesia, in line with rising surface temperatures and greenhouse gas concentrations'. Over the past decade, dozens have died in floods in the city and at least 280,000 people have had to leave their homes until the water receded. With parts of Jakarta now 4m lower than they were in 1970, Indonesia decided to build a new capital city - Nusantara - on a different island, Borneo, more than 1,200km (750 miles) away. It is further from the coast and will rely on a huge dam and reservoir to store river and rainwater. The plan is to purify and distribute water to all homes and offices in the new capital, eliminating the need to extract groundwater. However, the new city is controversial and development has slowed. There has been criticism of the $34bn price tag and its environmental impact on one of the most biodiverse places on the planet. Buildings in Ebute Metta, Lagos, where Rukkayat lives, are sinking - the white dotted line shows the highlighted structure's original position Five of the cities studied by NTU are in Africa, including Lagos in Nigeria. Last year, flooding affected more than 275,000 people there. Twenty-eight-year-old Rukkayat moved to Ebute Metta, in the east of the city, three years ago in search of work and a better life. But she could only afford to rent a house in a sinking area - one of the locations identified in the NTU report. 'It's hard to live in a place where it gets easily flooded if downpours or storms hit the city,' she says. 'I have to scoop water out of the corridor.' The walls of the house are cracked, the floor is damp and the roof leaks - a common situation in sinking areas, experts say. Both Lagos and Jakarta are facing rapid urbanisation and growing populations with more than half unable to access piped water, turning instead to pumping groundwater themselves. An animated line break showing water flowing under landmarks The bowl effect As many coastal cities deal with the combination of subsiding land and rising seas, they are looking for solutions - but these can sometimes contribute to other problems. Some, including Jakarta, Alexandria in Egypt and Ho Chi Minh City in Vietnam have built dykes, walls and sand barriers along their coastlines to try to prevent flooding from the sea. A seawall was built to stop seawater swamping homes in North Jakarta Alexandria has built concrete breakwaters to protect the city from the sea But as walls get higher and bigger, a 'bowl effect' can be created, says Prof Pietro Teatini of the University of Padova in Italy, potentially trapping rain and river water in areas and preventing it from flowing back into the sea. This can contribute to flooding. So, to drain excess water, Jakarta and Ho Chi Minh City are among those that have built pumping stations. However, this does not address the causes of subsidence or flooding. How Tokyo solved the problem When Tokyo found parts of its city were subsiding, it took a different approach and decided to tackle the root of the problem. The sinking slowed significantly in the 1970s after Tokyo imposed strict regulations on groundwater pumping. It also built a water supply management system, which scientists argue is the most efficient way to stop subsidence. The NTU study found that today the city is much more stable, although a few small areas have sunk by between 0.01 and 2.4cm per year between 2014 and 2020. So, how does Tokyo's system work? Almost all of Tokyo's water comes from forests and rivers controlled by two big dams outside the city. The water is purified in 10 plants and sent to a supply centre. The centre regulates the volume and pressure of the water. The centre distributes the water to homes and industries via pipes designed to resist earthquake damage. Despite the effectiveness of Tokyo's system, scientists are sceptical it can be applied widely given the high build and maintenance costs, says Prof Miguel Esteban of Waseda University in Japan. Nonetheless, he adds, some Asian cities still look at Tokyo's approach as a model. Taipei, for example, reduced groundwater extraction in the 1970s which, in turn, helped to slow down its subsidence rates. Many other cities - including Houston, Bangkok and London - also carefully regulate groundwater pumping to ensure it is neither too low nor too high. Some cities have tried different methods. Shanghai, for instance, has applied 'water injection, which works very well', says Prof Teatini. It injected purified water from the Yangtze River into the ground through wells that had previously been used to extract groundwater. Others, such as Chongqing in China and San Salvador in El Salvador, have adopted the principles of sponge cities. Instead of simply using non-porous concrete and asphalt in areas such as pavements, a sponge city makes use of surfaces that are designed to absorb water naturally, such as soil, grass and trees. The construction of parks, wetlands and green spaces is prioritised, along with lakes and ponds where water can be diverted and stored during the rainy season. The roof of this building on the edge of Chongqing is designed to absorb water and help manage heavy rainfall A residential complex in Berlin has been designed with areas to store and absorb water This may offer a 'more viable and sustainable solution, it costs only a tenth of building dams', says Prof Manoochehr Shirzaei of Virginia Tech University. But critics say that it is hard to add these features to existing developments and often they are not installed on a large enough scale to make a big difference. And behind any investment, there needs to be long-term political commitment, says Prof Shirzaei. 'Land subsidence emerges gradually over time, so to deal with that, we have to take difficult decisions which remain in place for decades,' he says, even if pumping restrictions are initially unpopular with voters who rely on wells and boreholes for water. Without change, experts warn there will be more people like Erna, fighting a losing battle as their homes gradually slip away. A note on methodology For its study the NTU chose coastal urban agglomerations within 50km (30 miles) of the coast, with a population of at least five million in 2020. It analysed satellite images, comparing data from 2014 to 2020 to estimate subsidence rates. The subsidence rate is measured from a reference point in each city, which scientists assume is more stable than others. However, if the reference point is also sinking or rising, other parts of the city might be sinking faster or slower than the measurements suggest. This could affect the BBC estimates of how many people are affected. The subsidence rates used here should therefore be seen as a relative measure, helping to identify which areas are likely more affected than others. A line break showing a wave

New coronavirus discovered in China ‘only small step' from infecting humans

A new coronavirus discovered in China is only a small step from mutating and causing another global pandemic, experts have warned. Scientists believe the variant, called HKU5-CoV-2, may infect a broader range of animals than Covid-19 – which caused millions of deaths – and may have more potential for jumping between species. US researchers fear that HKU5-CoV-2, found in China, in February, could also infect humans, leading to a widespread outbreak. The new study, published in Nature Communications, looked at a lesser-known group of coronaviruses called merbecoviruses, which includes HKU5 and MERS-CoV, which is responsible for the deadly Middle East Respiratory Syndrome. The team from Washington State University looked at how the new pathogen interacts with human cells. They found that a small change in the virus's spike protein could allow it to attach to human ACE2 cells in people's throats, mouths and noses. HKU5-CoV-2 can infect and replicate inside human cells in both the airways and gut. According to the World Health Organisation, about 35 per cent of people infected with Middle East Respiratory Syndrome die. Since 2012, some 27 countries have reported cases, leading to 858 known deaths due to the infection, which spread from camels. But when HKU5 was discovered in February, scientists warned against exaggerating the risks because it does not enter human cells as readily as Sars-CoV-2, which caused Covid-19. HKU5 was first detected in bats by scientists from the Chinese laboratory where some say Covid originated in 2019. Prof Michael Letko, a virologist who co-led the study, said: 'HKU5 viruses in particular really hadn't been looked at much, but our study shows how these viruses infect cells. 'What we also found is HKU5 viruses may be only a small step away from being able to spill over into humans.' When Covid-19 emerged it was widely blamed on markets in China where different breeds of wild animal are kept caged and often slaughtered close to other animals. Meat is sold at the open-air stalls. Critics said the markets were the perfect breeding ground for new zoonotic diseases – those that spread to humans – to emerge. The scientists, whose experiments studied how the new pathogen interacts with human cells, believe the virus would have to carry certain mutations if it were to infect humans. 'These viruses are closely related to MERS, so we have to be concerned if they ever infect humans,' Prof Letko said. 'While there's no evidence they've crossed into people yet, the potential is there and that makes them worth watching.'

China surpasses German engineering with world's tallest wind turbine

Other countries compete to build the tallest skyscraper, or the biggest Ferris wheel. China and Germany are more serious about their engineering: they compete for the prize of having the biggest wind turbine. One of China's two leading wind turbine companies, Dongfang Electric, announced on Friday it had completed a key test on the latest machine that, when it goes into service shortly, will break that record. Standing 340 metres from its base in the Pacific, off the coast of the country's Fujian province, to the tip of its blades when they rotate to their highest points, it will be the first wind turbine to be taller than the Eiffel Tower. Dongfang — meaning the East — said it had finished load testing a prototype blade for the turbine, itself 150 metres long. 'We're harnessing the power of tech to plant the seeds of a greener future,' it said in celebration. 'Every blade carries a low-carbon dream, ready to catch the wind and grow strong.' China under President Xi has put huge economic weight on not only an ever-expanding industrial base but also being at the forefront of green technologies. With no room for political opposition, and a heavy continuing reliance nationally on coal and other fossil fuels at the same time, there is little of the public debate around wind power that western European companies have faced. China already makes more than 80 per cent of the world's solar panels. Its low cost base — unfairly subsidised, according to western rivals — is also undercutting and starting to dominate American and European production in wind power too. A worker at the Dongfang factory operates a robotic arm At present the wind turbine claimed to be the world's highest was constructed by another Chinese company, Mingyang, and operates off the southern Chinese island of Hainan. Its hub is at the same height as Dongfang's — 185 metres off the ground — but its blades are a few metres shorter. A similarly sized turbine is already operating at the site to which the Dongfang blades are believed to be heading, the Fujian Fuzhou Offshore Wind Power Industrial Park. Its maximum capacity is 18MW of electricity, and the Hainan turbine is 20MW, which the new turbine will surpass by 6MW. According to estimates, that will be enough at average 10 metres per second windspeeds to power 55,000 homes on its own. Britain's tallest wind turbines — at the Longhill Burn Wind Farm in West Lothian, Scotland — stand up to 150m tall. The blades reach as high as 200m. How long any of these three monsters maintain their dominance is unclear. As Germany tries to reclaim its traditional global leadership in engineering — and tries to stave off Chinese competition — its companies are also building higher. A turbine being designed and built by Gicon, a German conglomerate, will stand at 363 metres from toe to the tip of the vertical blade. It, however, is based on a novel design, in which smaller blades rotate from a 300-metre high lattice structure itself influenced by the design of the Eiffel Tower. It will, however, be the second highest man-made object in Germany, after the Berlin TV Tower.
