China says it is on track to put boots on Moon by 2030 as Nasa's Artemis struggles with delay

Yahoo28-04-2025
China's plans to put boots on the Moon by 2030 are on track with tests proceeding as per schedule, the country's space agency said, following an early trial of its lunar landing spacecraft last week.
The Asian giant's timeline to land astronauts back on the Moon is still behind the schedule of Nasa's Artemis II crewed mission, which has been delayed until 2027.
Last week, China's space agency announced the successful trial of its prototype Mengzhou next-generation reusable spacecraft and the Lanyue lunar surface lander, adding that their development was 'progressing smoothly', SCMP reported.
In subsequent months, the space agency plans to test the safety and reliability of the country's three-stage superheavy rocket, Long March 10, as well as the Mengzhou spacecraft.
Mengzhou has two modules, one that would return to Earth, and another expendable module to provide propulsion, power and life support for a crew of about six astronauts while they are in space.
'The Long March 10 and Mengzhou spacecraft are carrying out prototype development and testing as planned,' said Lin Xiqiang, deputy director of the China Manned Space Agency (CMSA).
Further ground tests would also assess the spacecraft's emergency escape systems, developed to get the crew to safety in the event of a launch failure.
In earlier reports, the space agency said it expected the spacecraft to attain crewed flight capability around 2027-2028.
'We will strive to ensure the successful completion of all tests to lay a solid foundation for launching humans to the moon as scheduled,' the CMSA deputy director said.
Meanwhile, Nasa's Artemis III crewed mission to the lunar surface has been facing a series of delays.
Both the Chinese and American missions are aiming for a landing near the lunar south pole thought to be rich in water-ice, a resource critical for establishing bases.
Nasa announced in December that its mission to put boots on the Moon would be delayed to mid-2027, after problems were discovered with the heat shield on its Orion spacecraft.
Extensive tests found that material on the spacecraft's heat shield wore away differently than expected.
The heat shield is supposed to provide thermal protection for Orion's crew from the nearly 2,760 degrees Celsius (5,000 degrees Fahrenheit) of temperatures generated when Orion returns through Earth's atmosphere.
The American space agency has been testing changes to Orion's trajectory and enhancements to the heat shield to ensure the spacecraft can keep the crew safe.
'The updates to our mission plans are a positive step toward ensuring we can safely accomplish our objectives at the Moon and develop the technologies and capabilities needed for crewed Mars missions,' said Catherine Koerner, associate administrator for Nasa's Exploration Systems Development Mission Directorate.

This tasty piece of cheese may give you nightmares—literally

A study of more than 1000 college students found that there was a strong association between nightmares and eating cheese, primarily among those with food allergies or lactose intolerance. Photograph by Rebecca Hale, National Geographic Anecdotal claims that eating cheese before bed causes nightmares were once so prevalent that in 2005 the British Cheese Board sponsored a study on the matter. For the week-long experiment, 200 volunteers (100 women, 100 men) reported what variety of cheese they ate before bed and what their dreams were like. Though the study (more public relations than science) was never published in a peer-review journal, the details were fascinating: Stilton cheese reportedly induced weird dreams, such as one about a vegetarian crocodile that wanted to eat human children. Cheddar, on the other hand, was associated with dreams of celebrities. A hundred years prior, American cartoonist Winsor McCay made cheese the antagonist of his early turn-of-the-century comic strip. In Dream of the Rarebit Fiend, characters are plagued by bizarre, even nightmarish dreams, usually after eating Welsh rarebit, a mildly spicy cheese toast. A study published this June in the journal Frontiers in Psychology has finally revealed clues for why certain foods might lead to more fretful sleep. In a survey of 1,000 participants, nightmares after eating cheese or dairy products were much more common in people who were lactose intolerant. It makes sense that having such uncomfortable symptoms while sleeping could influence dreams, says Tore Nielsen, the study's lead author and a neuroscientist at Université de Montréal who studies dreams and nightmares. 'We know that pain influences dreams. We know that other body sensations—just touching a dreaming person—can enter into their dreams,' he says. 'These pathways for influencing dreams exist for sure.' How scientists studied certain foods and dreams Nielsen's first paper examining food and nightmares published in 2015. Then, he asked 396 university students if they thought particular foods gave them bizarre or disturbing dreams. Almost 18 percent said food played a role, and dairy or cheesy dishes like pizza and poutine (the study was done in Canada) were named as the primary culprits. Nielsen's recent study found a much smaller general relationship between food and dreams. Only 5.5 percent of those surveyed reported that their dreams or nightmares were caused by food. 'But that's only part of the results, because we don't really know how accurate these participants are in detecting specific cause, effect relationships,' says Nielsen. 'This is just an impression. And the impression could be based on folklore, mythology, even like just things that they picked up, or misattributions, you know, I eat something late, I'm gonna have bad dreams.' Yet when the researchers analyzed data about gastrointestinal symptoms—bloating, gas, diarrhea, cramps, pain—they found a distinct link: the lactose intolerant participants with the worst GI symptoms had the worst nightmares. (Learn why some people are better off sleeping on their sides.) The study authors also collected data from what Nielsen calls a 'style of eating questionnaire,' and found that nightmares correlated with not paying attention to one's own feelings of satiety and using the clock rather than hunger to decide when to eat. 'Ignoring those bodily signals, especially, were associated with having nightmares,' Nielsen said. The general eating habits that affect sleep In addition to the usual suspects—caffeine and alcohol—highly-processed foods, sugar, and refined carbohydrates can interfere with a good night's sleep, say Marie-Pierre St-Onge, director of the Center of Excellence for Sleep and Circadian Research at Columbia University. Her research has shown that eating more fruits and vegetables can lead to less fragmented sleep, while more fiber, whole grains, and nuts are helpful for better sleep overall. Low-fiber diets and diets high in saturated fat, on the other hand, are associated with lighter, less restorative sleep with more frequent arousals. And while a poor diet can cause poor sleep, too-little sleep can make it more challenging to maintain diet, according to research by Erica Jansen, a nutritional epidemiologist at the University of Michigan. 'When you bring people into the lab and deprive them of sleep, whether that's a whole night of sleep deprivation or you limit their sleep to four or five hours, they eat differently the next day,' she says. 'They eat more calories. They have higher cravings for energy dense foods. They choose to eat more refined carbs, more fats.' The mechanisms behind this aren't clear, but Jansen says that hormones, such as leptin and ghrelin, which are known to influence appetite, are altered by poor sleep. If an unhealthy diet leads to poor sleep, does it have anything to do with nightmares? Maybe. Jansen speculates that waking up more frequently, a pattern associated with foods like cheese that are high in saturated fat, can disrupt the balance between REM (rapid eye movement) and non-REM sleep. Most dreaming is done during REM sleep, and you're more likely to remember a dream if you wake up in the middle of it, says Jansen: 'I think that one possible mechanism could be that people are waking up more, so therefore they're remembering their dreams more.' If bad dreams are caused by a generally poor diet, and the nightmarish effect of cheese is limited mostly to the lactose intolerant, how did cheese get such a bad reputation? (What mummies revealed about the world's oldest cheese.) Lucy Long, academic folklorist, director of the non-profit educational group Center for Food and Culture, and author of The Food and Folklore Reader, speculates that the association between cheese with nightmares is a relatively niche and recent belief. The idea that cheese is responsible for bad sleep is not common in many cultures, and on the contrary, warm milk is often thought to ensure peaceful sleep, she says. 'When people say, 'Oh, it's folklore,' sometimes it's actually something that was created in popular culture or by marketing.' It's possible that the idea that cheese causes nightmares simply owes its popularity to Winsor McCay and his Rarebit Fiend.

Heart Problems Rising in This Group

Cardiovascular health appears to be suboptimal and in decline among older adults with high blood pressure, heart failure, or stroke compared with those without these conditions, according to new research published in the Journal of the American Heart Association . Using data from the National Health and Nutrition Examination Survey from 2013 to 2018, researchers examined changes in cardiovascular health, as measured by the American Heart Association's (AHA's) Life's Essential 8 (LE8), in adults aged 65 years or older with self-reported hypertension, stroke, heart failure, coronary heart disease, myocardial infarction, or angina. LE8's metrics include diet, physical activity, nicotine use, sleep health, BMI, blood pressure, blood lipids, and blood sugar, according to the study author Donald M. Lloyd-Jones, MD, ScM, from the Framingham Center for Population and Prevention Science at Boston University, Boston. Donald M. Lloyd-Jones, MD, ScM 'LE8 scores have been studied in hundreds of populations across the globe, but most of these studies have focused on people who do not yet have [cardiovascular disease] CVD,' he said. 'We examined current levels and trends of LE8 scores in older US adults who are living with CVD, and we [hypothesized] that LE8 would be a means for extending life and avoiding future cardiovascular events.' Opportunities to Reduce Risk Among 3050 older adults with and without CVD in the database, the researchers found the gap in cardiovascular health between people with and without CVD was primarily attributable to differences in blood pressure and physical activity. When Lloyd-Jones' group compared LE8 scores between the two groups, they found people with no CVD had an average cardiovascular health score of 68 out of 100. The average score for those with at least one cardiovascular condition fell below 60 and dropped further with each additional CVD. Throughout the study period, LE8 scores decreased by 4.1% among people with hypertension, 11.5% among those with a history of stroke, and 15.2% among those with heart failure. Nieca Goldberg, MD, clinical associate professor of medicine at NYU Grossman School of Medicine, New York City, and medical director of Atria New York City, said clinicians can help patients improve their odds of avoiding cardiovascular problems. Nieca Goldberg, MD 'This study highlights important information for [older adults] at high risk for cardiac events,' she said, noting that attaining blood pressure < 120/80 mm Hg is key. 'Patients should be encouraged to take blood pressure measurements at home so that they can be engaged in their healthcare,' she said. Goldberg suggested clinicians ask their patients who avoid physical activity what prevents them from exercising. 'Is it an orthopedic limitation such as knee and hip pain or back pain? In such a case, the patient may need physical therapy to increase their physical activity,' she said. Goldberg also recommended that clinicians emphasize the importance of a low-salt diet that includes at least five servings of fruits and vegetables daily, lean proteins, and foods that contain calcium while avoiding processed foods, which tend to be high in salt and sugar. Lloyd-Jones added that using the AHA's online tool, MyLifeCheck, to measure LE8 can help quantify the cardiovascular health of older individuals with and without CVD and 'present opportunities to improve health, prolong lifespan, and reduce the further burden of CVD.' 'This can also help empower patients to control and improve modifiable aspects of their health,' he said. Goldberg declared having no financial disclosures.

NASA's Webb telescope discovers previously unknown moon orbiting Uranus

WASHINGTON - Astronomers using what is considered to be the most powerful space telescope ever built say they have discovered a previously unknown moon orbiting Uranus, expanding the count of the planet's natural satellites to at least 29. According to NASA, scientists using the James Webb Space Telescope spotted the small moon earlier this year and gave it the initial designation of S/2025 U1. "This object was spotted in a series of 10 40-minute long-exposure images captured by the Near-Infrared Camera (NIRCam)," Maryame El Moutamid, lead scientist at the Southwest Research Institute's Solar System Science and Exploration Division in Boulder, Colorado, said in a statement. "It's a small moon but a significant discovery, which is something that even NASA's Voyager 2 spacecraft didn't see during its flyby nearly 40 years ago." The moon was estimated to be just six miles across and likely serves as the primary reason why previous missions, including a flyby by Voyager 2, have missed seeing the natural satellite until this year. S/2025 U1 is said to be the fourteenth member of Uranus' inner satellite system and the twenty-ninth overall. See The Objects Humans Left Behind On The Moon "No other planet has as many small inner moons as Uranus, and their complex inter-relationships with the rings hint at a chaotic history that blurs the boundary between a ring system and a system of moons," Matthew Tiscareno, a researcher at the SETI Institute in Mountain View, California, and a member of the Webb science team, stated. "Moreover, the new moon is smaller and much fainter than the smallest of the previously known inner moons, making it likely that even more complexity remains to be discovered." According to Nasa, Saturn has the most moons in our solar system, with the last count putting the number at 274, while both Mercury and Venus don't have any natural satellites. Like Uranus' other satellites, the new moon will eventually receive a formal name from the International Astronomical Union. The planet's moons have traditionally been named after characters from the works of William Shakespeare and Alexander Pope. Some of the known moons are Miranda, Ariel, Umbriel, Titania and Oberon. The Moon Is Now Considered A Vulnerable Cultural Heritage Site Astronomers say the Webb's latest findings reinforce the need for a future spacecraft mission around one of the least-studied planets in the solar system. NASA and other space agencies have discussed launching an orbiter in the 2030s, which would study the planet's atmosphere, rings and apparent growing number of article source: NASA's Webb telescope discovers previously unknown moon orbiting Uranus
