An anonymous reader shared this report from the senior space editor at Ars Technica: In a new report, the federal department charged with analyzing how efficiently U.S. taxpayer dollars are spent, the Government Accountability Office, says NASA lacks transparency on the true costs of its Space Launch System rocket program. Published on Thursday, the new report (see .pdf) examines the billions of dollars spent by NASA on the development of the massive rocket, which made a successful debut launch in late 2022 with the Artemis I mission. Surprisingly, as part of the reporting process, NASA officials admitted the rocket was too expensive to support its lunar exploration efforts as part of the Artemis program. "Senior NASA officials told GAO that at current cost levels, the SLS program is unaffordable," the new report states...

Moreover, the report indicates that NASA has not regularly updated its five-year production cost estimates for the rocket. The report also cites concerns about development costs of future hardware for NASA's big-ticket rocket program, including the Exploration Upper Stage. Another problem with NASA's cost estimates is that they do not appear to account for delays to Artemis missions. It is probable that the Artemis II mission, a crewed flight around the Moon, will launch no earlier than 2025. The Artemis III crewed landing will likely slip to at least 2026, if not more, with additional delays down the line...

NASA officials interviewed by the Government Accountability Office acknowledged that they were concerned about the costs of the SLS rocket. "NASA recognizes the need to improve the affordability of the SLS program and is taking steps to do so," the report states. "Senior agency officials have told us that at current cost levels the SLS program is unsustainable and exceeds what NASA officials believe will be available for its Artemis missions."

Scientists have grown humanized kidneys in pigs, raising the prospect of human organs being grown inside animals. The Guardian reports: The research involved creating human-pig chimeric embryos containing a combination of human and pig cells. When transferred into surrogate pig mothers, the developing embryos were shown to have kidneys that contained mostly human cells, marking the first time that scientists have grown a solid humanized organ inside another animal. The kidneys were not entirely human as they included vasculature and nerves made mostly from pig cells, meaning they could not be used for transplantation in their current form. It is not clear whether the challenge of making a wholly human organ would be achievable with current genetic engineering techniques.

Aside from the kidneys, the embryos were dominated by pig cells, with very few human cells in the brain or central nervous system. The potential for a humanized brain is a serious ethical concern for research involving hybrid embryos and one of the reasons for tight legal restrictions on research in many countries. [...] After being cultivated in the lab, the chimeric embryos were transferred to 13 surrogate sows. After either 25 or 28 days, the gestation was terminated and embryos were extracted and assessed. The embryos had structurally normal kidneys for their stage of development, showing the tubules that would eventually connect the kidney to the bladder, and were composed of 50-60% human cells. Very human neural cells were found in the brain and spinal cord. The research has been published in the journal Cell Stem Cell.

SpaceX's Starship rocket is fully stacked and ready to launch again. According to Elon Musk, the company is just waiting for the Federal Aviation Administration (FAA) to approve the launch license. Ars Technica reports: That caveat is a big one because the Federal Aviation Administration is still reviewing paperwork and data from SpaceX about the first launch attempt of Starship in April 2023. That flight ended after about 90 seconds due to engine problems and other issues with the booster. The FAA has been reviewing data from that accident, including the environmental implications at the launch site and the delayed activation of the rocket's flight termination system. Following this accident, SpaceX prepared and submitted a "mishap investigation report" to the FAA. After reviewing the report, the FAA will identify corrective actions that the company must make ahead of its second test flight to ensure the safety of people, property, and wildlife near the South Texas launch site, which is surrounded by wetlands and the Gulf of Mexico. [...]

During the upcoming test flight, Starship will carry no payloads but will instead seek to demonstrate the performance of the booster's 33 Raptor rocket engines, stage separation, and ignition of Starship's six engines. Under a nominal flight, Starship will complete nearly three-quarters of an orbit around Earth before splashing down in the Pacific Ocean, north of the Hawaiian island of Kauai. The launch date is pending regulatory approval, but it is not expected to occur before the middle of September.

An anonymous reader quotes a report from the BBC: Scientists have grown an entity that closely resembles an early human embryo, without using sperm, eggs or a womb. The Weizmann Institute team say their "embryo model", made using stem cells, looks like a textbook example of a real 14-day-old embryo. It even released hormones that turned a pregnancy test positive in the lab. The ambition for embryo models is to provide an ethical way of understanding the earliest moments of our lives. This research, published in the journal Nature, is described by the Israeli team as the first "complete" embryo model for mimicking all the key structures that emerge in the early embryo.

Instead of a sperm and egg, the starting material was naive stem cells which were reprogrammed to gain the potential to become any type of tissue in the body. Chemicals were then used to coax these stem cells into becoming four types of cell found in the earliest stages of the human embryo: epiblast cells, which become the embryo proper (or foetus); trophoblast cells, which become the placenta; hypoblast cells, which become the supportive yolk sac; and extraembryonic mesoderm cells. A total of 120 of these cells were mixed in a precise ratio -- and then, the scientists step back and watch.

About 1% of the mixture began the journey of spontaneously assembling themselves into a structure that resembles, but is not identical to, a human embryo. The embryo models were allowed to grow and develop until they were comparable to an embryo 14 days after fertilization. In many countries, this is the legal cut-off for normal embryo research. The hope is embryo models can help scientists explain how different types of cell emerge, witness the earliest steps in building the body's organs or understand inherited or genetic diseases. Already, this study shows other parts of the embryo will not form unless the early placenta cells can surround it. There is even talk of improving in vitro fertilization (IVF) success rates by helping to understand why some embryos fail or using the models to test whether medicines are safe during pregnancy.

One million lorries of sand a day are being extracted from the world's oceans, posing a "significant" threat to marine life and coastal communities facing rising sea levels and storms, according to the first-ever global data platform to monitor the industry. From a report: The new data platform, developed by the UN Environment Programme (Unep), tracks and monitors dredging of sand in the marine environment by using the AIS (automatic identification systems) data from ships. Using data from 2012-19, Marine Sand Watch estimates the dredging industry is digging up 6bn tonnes of marine sand a year, a scale described as "alarming." The rate of extraction is growing globally, Unep said, and is approaching the natural rate of replenishment of 10bn to 16bn tonnes of sand flowing into the sea from rivers and needed to maintain coastal structure and ecosystems.

The platform has identified "hotspots" including the North Sea, south-east Asia and the east coast of the United States as areas of concern. In many places where extraction is more intense, including parts of Asia, marine sand is being extracted well beyond the rate at which it is being replenished from rivers. [...] Developed by GRID-Geneva, a centre for analytics within Unep, Marine Sand Watch has trained artificial intelligence to identify the movement of dredging vessels from its AIS data. It has data from 2012-19 from Global Fishing Watch, a company set up to track commercial fishing activities using AIS data from fishing vessels, but is working on more recent data.

More than 200 scientists have signed onto a letter pushing for "responsible" research into ways to trap planet-heating carbon dioxide in the world's oceans. They want to take urgent action on the climate crisis, while making sure they don't trigger any new problems by relying on oceans to help in the fight. From a report: Polluters have trashed the world's atmosphere with carbon dioxide emissions from fossil fuels. That blanket of pollution is already warming the planet and causing more extreme weather disasters. One way to keep climate change from getting worse is to take some of those historic emissions out of the atmosphere.

Oceans already do that for us, absorbing and holding around 50 times more carbon than the atmosphere. What if humans could supercharge that ability? That's what scientists want to better understand, along with any side effects that might come with messing with the chemistry of our oceans. Startups are already developing new technologies to sequester more CO2 in the sea. But there's still a lot we don't know about what impact that might have or what strategies might be most successful, the letter says.

Invasive species are costing the world at least $423bn every year and have become a leading threat to the diversity of life on Earth, according to a UN assessment. From a news report: From invasive mice that eat seabird chicks in their nests to non-native grasses that helped fuel and intensify last month's deadly fires in Hawaii, at least 3,500 harmful invasive species have been recorded globally in every region, spread by human travel and trade. Their impact is destructive for humans and wildlife, sometimes causing extinctions and permanently damaging the healthy functioning of an ecosystem.

Leading scientists say the threat posed by invasive species is under appreciated, underestimated and sometimes unacknowledged, with more than 37,000 alien species now known to be introduced around the world and about 200 establishing themselves each year. While not all will become invasive, experts say there are significant tools to mitigate their spread and impact, protecting and restoring ecosystems in the process.

"Invasive alien species are a major threat to biodiversity and can cause irreversible damage to nature, including local and global species extinctions, and also threaten human wellbeing," wrote Prof Helen Roy, Prof Anibal Pauchard and Prof Peter Stoett, who led the research. "It would be an extremely costly mistake to regard biological invasions only as someone else's problem," said Pauchard. "Although the specific species that inflict damage vary from place to place, these are risks and challenges with global roots but very local impacts facing people in every country, from all backgrounds and in every community -- even Antarctica is being affected."

An anonymous reader shared this report from the Washington Post: On April 26, 1986, the infamous explosion at a Chernobyl nuclear power plant unleashed large amounts of radiation into the atmosphere, an event that contaminated wildlife across country lines. The radiation levels seen in animals as a result has decreased in recent years — with the exception of one animal: the wild boar. For years, scientists questioned why levels of a radioactive isotope known as cesium-137 have remained surprisingly high in wild boars rooting around Germany and Austria, while decreasing in other deer and roe deer. In a new study released last week, a team of researchers finally solved this "wild boar paradox."

They uncovered that the main radioactive source is not the Chernobyl accident but nuclear weapons testing from the 1960s...

Radioactive cesium results from both nuclear weapons explosion and nuclear energy production. The element comes in different isotopic composition, cesium-135 and cesium-137, depending on the source. By analyzing the ratio of these amounts, the researchers can pinpoint the source of the radiation... In the nearly 50 collected meat samples, the team found 88 percent of the samples were above Germany's regulatory limits for radioactive cesium in food. Calculating the ratio of cesium isotopes in the samples, they found that nuclear weapons testing accounted for 10 to 68 percent of the contamination. Even if the Chernobyl accident had never happened, "some of the wild boars would actually still exceed the regulatory limits for food safety limits only because of the weapons tests today," said Georg Steinhauser, a radiochemist at TU Wien and author of the new study. "I think this is pretty mind-blowing because they were 60 years ago."

Steinhauser said the wild boars probably ingested the cesium from contaminated deer truffle mushrooms, which they dig up and eat during the winter when corn and acorns on the ground are scarce. Cesium seeps through the soil and is absorbed by the mushrooms, as if it were a nutrient. This also explains why observations show radioactivity levels in wild boar are higher in the winter. While cesium from both the nuclear weapons testing and the Chernobyl accident spread through the soil, Steinhauser said, the mushrooms appear to have fully absorbed the source from the nuclear weapons testing so far. Cesium seeps very slowly through the soil, sometimes only one millimeter per year, he said. Deer truffles, located between 20 and 40 centimeters, have already absorbed the "older" cesium from six decades ago. The "younger" cesium from Chernobyl has likely not fully integrated or is just now integrating at the soil depths where the mushrooms are located. But it could be bad news when the cesium from Chernobyl does reach the mushrooms — radioactivity levels could go up higher.
The study's author says his study isn't arguing for or against the use of nuclear energy — but does say that "it has to be done responsibly." He calls the study's results "a cautionary tale that we have to take good care of our environment," said Steinhauser. "Once released, a radioactive substance can never be unreleased again — and nature doesn't forget."

"Viasat Inc. has more than $1 billion of orbiting satellites in trouble," reports Bloomberg, "and space insurers are girding for market-rattling claims." The company's roughly $1 billion ViaSat-3 Americas satellite, central to expanding its fixed-broadband coverage and fending off rivals including Elon Musk's Starlink, suffered an unexpected problem as it deployed its antenna in orbit in April. Should Viasat declare it a total loss, industry executives estimate the claim would reach a record-breaking $420 million and, in turn, make it harder — and more expensive — for other satellite operators to get insurance... Viasat on Aug. 24 reported another stricken spacecraft, saying its Inmarsat-6 F2 satellite launched in February suffered a power problem. The failure may end the craft's useful life and result in a $350 million insurance claim, Space Intel Report said.

Viasat's troubles in orbit come a few years after big-name insurers like American International Group Inc. and Allianz SE have shuttered their space portfolios. That's left a smaller pool of providers to absorb the risks in the notoriously high-stakes $553 million market...

Following news of the Inmarsat-6 anomaly, Viasat and other industry participants "will likely experience significant challenges with obtaining insurance for future satellite launches," [investment banking firm] William Blair's Louie DiPalma said in an Aug. 25 note... In 2019, the total losses from satellite claims amounted to $788 million, which overwhelmed the total premiums for the year at $500 million, according to launch and satellite database Seradata. In the years that followed, big names like American International Group Inc., Swiss Re AG, and Allianz SE all closed the door on satellite insurance.
Earlier this month Viasat's CEO says before deciding whether they'll file a claim, "There's no consequences to us taking another couple or three months to get good measurements and then making those decisions."

To complete one full rotation around its axis it takes the moon 655 hours. So a single "lunar day" is 13.64 earth days.

But sunset has finally come for India's Chandrayaan-3 spacecraft and its Pragyan rover, writes long-time Slashdot reader Geoffrey.landis , and the rover has switched off for the coming 655-hour night: With luck from the moon gods, it will wake up with the sunrise in 14 days. But, even if not, mission accomplished! It was designed for fourteen days of operation, the daylight period. In that time the rover accomplished just over a hundred meters (American units: one football field) of traverse, examining and chemically analyzing the surface.
"The Indian Express newspaper said the electronics on board the Indian moon mission werenâ(TM)t designed to withstand very low temperatures, less than -120 C (-184 F) during the nighttime on the moon," according to the Associated Press. But the rover's accomplishments already include making the first-ever measurements of the south pole's near-surface Lunar plasma, and confirming the presence of aluminum, calcium, chromium, titanium, manganese, and silicon. There's also sulphur, iron, oxygen and other elements on the moon, Reuters reports, citing a statement from the Indian Space Research Organisation (ISRO): The Pragyan rover from the Chandrayaan-3 spacecraft was "set into Sleep mode" but with batteries charged and receiver on, the ISRO said in a post on X, formerly Twitter, late on Saturday. "Hoping for a successful awakening for another set of assignments!" ISRO said. "Else, it will forever stay there as India's lunar ambassador."
Earlier this week the ISRO posted footage of the rover completing a near-pirouette to search for the safest route.

"The solar panel is oriented to receive the light at the next sunrise expected on September 22, 2023," the ISRO posted Saturday.

A biotech company has conducted a small-scale trial involving the implantation of lab-made neurons into the brains of 12 people with Parkinson's disease. The implanted neurons are designed to produce dopamine, which is deficient in Parkinson's patients, and early data suggests they may have survived and improved symptoms in some cases. MIT Technology Review reports: The study is one of the largest and most costly tests yet of embryonic-stem-cell technology, the controversial and much-hyped approach of using stem cells taken from IVF embryos to produce replacement tissue and body parts. The replacement neurons were manufactured using powerful stem cells originally sourced from a human embryo created an in vitro fertilization procedure. According to data presented by Henchliffe and others on August 28 at the International Congress for Parkinson's Disease and Movement Disorder in Copenhagen, there are also hints that the added cells had survived and were reducing patients' symptoms a year after the treatment.

These clues that the transplants helped came from brain scans that showed an increase in dopamine cells in the patients' brains as well as a decrease in "off time," or the number of hours per day the volunteers felt they were incapacitated by their symptoms. However, outside experts expressed caution in interpreting the findings, saying they seemed to show inconsistent effects -- some of which might be due to the placebo effect, not the treatment. Because researchers can't see the cells directly once they are in a person's head, they instead track their presence by giving people a radioactive precursor to dopamine and then watching its uptake in their brains in a PET scanner. "It is encouraging that the trial has not led to any safety concerns and that there may be some benefits," says Roger Barker, who studies Parkinson's disease at the University of Cambridge. But Barker called the evidence the transplanted cells had survived "a bit disappointing."

He said the results were not so strong, adding that it's "still a bit too early to know" whether the transplanted cells took hold and repaired the patients' brains.

"Given that too many schools don't teach calculus, chemistry and physics, CalTech is allowing potential undergraduates to demonstrate their ability in these fields by using Khan Academy," writes Slashdot reader Bruce66423. Los Angeles Times reports: One of Caltech's alternative paths is taking Khan Academy's free, online classes and scoring 90% or higher on a certification test. Sal Khan, academy founder, said Caltech's action is a "huge deal" for equitable access to college. While Caltech is small -- only 2,400 students, about 40% of them undergraduates -- Khan said he hoped its prestigious reputation would encourage other institutions to examine their admission barriers and find creative solutions to ease them. The Pasadena-based institute, with a 3% admission rate last year, boasts 46 Nobel laureates and cutting-edge research in such fields as earthquake engineering, behavioral genetics, geochemistry, quantum information and aerospace. "You have one of the most academically rigorous schools on the planet that has arguably one of the highest bars for admission, saying that an alternative pathway that is free and accessible to anyone is now a means to meeting their requirements," said Khan, whose nonprofit offers free courses, test prep and tutoring to more than 152 million users. [...]

The impetus for the policy change began in February, when Pallie, the admissions director, and two Caltech colleagues attended a workshop on equity hosted by the National Assn. for College Admission Counseling. They were particularly struck by one speaker, Melodie Baker of Just Equations, a nonprofit that seeks to widen math opportunities. As Baker pointed out the lack of access to calculus for many students, Pallie and her team began to question Caltech's admission requirement for the course, along with physics and chemistry. Pallie and Jared Leadbetter, a professor of environmental microbiology who heads the faculty admissions committee, began to look into potential course alternatives. Pallie connected with Khan's team, which started a second nonprofit, Schoolhouse.world, during the pandemic in 2020 to offer free tutoring. Peer tutors on the platform certify they are qualified for their jobs by scoring at least 90% on the course exam and videotaping themselves explaining how they solved each problem on it. The video helps ensure that the students actually took the exam themselves and understand the material. That video feature gave Caltech assurances about the integrity of the alternative path.

Under the new process, students would take a calculus, physics or chemistry class offered by Khan Academy and use the Schoolhouse platform to certify their mastery of the content as tutors do with a 90% score or better on the exam and a videotaped explanation of their reasoning. Proof of certification is required within one week of the application deadline, which is in November for early action and January for regular decisions. Pallie and Leadbetter also wanted to test whether the Khan Academy courses are sufficiently rigorous. Several Caltech undergraduates took the courses to assess whether all concepts were covered in enough breadth and depth to pass the campus placement exams in those subjects. Miranda, a rising Caltech junior studying mechanical engineering, took the calculus course and gave it a thumbs-up, although she added that students would probably want to use additional textbooks and other study materials to deepen their preparation for Caltech.

Hot on the heels of its lunar landing success, India is readying to blast a probe even deeper into space to study the sun. From a report: The country's first solar observation mission, named Aditya-L1, is set to be launched from India's main spaceport on Sriharikota, an island off the southern state of Andhra Pradesh, at 11:50 a.m. local time on Saturday. The spacecraft is scheduled to spend 125 days traveling 1.5 million kilometers (932,000 miles) to its destination, a point in space where objects stay put and consume less fuel.

While arriving there would be an impressive achievement for ISRO, the Indian space agency, Aditya-L1 would have gone just a fraction of the 150 million km between Earth and the sun. For ISRO, success would be another major feat after India became the first country to land a spacecraft close to the lunar south pole in August. India has more ambitious projects in the works. A human spaceflight program aims to launch astronauts into orbit for the first time possibly by 2025, ISRO Chairman S Somanath said in an interview with news agency Asian News International. ISRO and NASA plan to cooperate on sending astronauts to the International Space Station and India is in discussions with Japan to work together on a mission.

The centenary of the Great Kanto earthquake brings angst, and lessons for the world. From a report: Every year on September 1st, Japan's ministers trek by foot to the prime minister's office to take part in a crisis simulation. Across the country, local officials and schoolchildren drill for disasters. The date marks the Great Kanto earthquake, a 7.9-magnitude tremor that struck near the capital back in 1923. The ensuing disaster killed at least 105,000 people, including around 70,000 in Tokyo itself, destroyed 370,000 homes and changed the course of Japanese history.

This year's centenary of the disaster has occasioned much commemoration -- and angst. What will happen when the next Big One hits? Seismologists cannot predict earthquakes, but their statistical models, which are based on past patterns, can estimate the likelihood of one. The city government's experts reckon there is a 70% chance of a magnitude 7 or higher quake hitting the capital within the next 30 years. Far fewer people will probably die than during the disaster in 1923, thanks to better technology and planning: the worst case foresees some 6,000 deaths in the city. But millions of lives will be upended.

Another, similarly likely scenario could be much worse. A Nankai Trough earthquake, envisaged south of Kansai, Japan's industrial heartland, could trigger a tsunami; as many as 323,000 might be killed, according to an official estimate. Japan's approach to the risks of such catastrophes offers insights for a warming world facing more frequent disasters. Quakes of this size could "challenge the survival of Japan as a state" and send economic shock waves around the globe, says Fukuwa Nobuo of Nagoya University. After the next Tokyo quake, recovering basic city functions could take weeks and rebuilding the capital could take years; direct damage alone could run to as much as $75bn. One piece of research estimates that gdp would dip by 11% following a Nankai earthquake.

Researchers in China have found evidence suggesting that 930,000 years ago, the ancestors of modern humans suffered a massive population crash. They point to a drastic change to the climate that occurred around that time as the cause. The New York Times: Our ancestors remained at low numbers -- fewer than 1,280 breeding individuals -- during a period known as a bottleneck. It lasted for over 100,000 years before the population rebounded. "About 98.7 percent of human ancestors were lost at the beginning of the bottleneck, thus threatening our ancestors with extinction," the scientists wrote. Their study was published on Thursday in the journal Science.

If the research holds up, it will have provocative implications. It raises the possibility that a climate-driven bottleneck helped split early humans into two evolutionary lineages -- one that eventually gave rise to Neanderthals, the other to modern humans. But outside experts said they were skeptical of the novel statistical methods that the researchers used for the study. "It is a bit like inferring the size of a stone that falls into the middle of the large lake from only the ripples that arrive at the shore some minutes later," said Stephan Schiffels, a population geneticist at Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.

The U.S. Department of Health and Human Services (HHS) has recommended easing restrictions on marijuana, a department spokesperson said on Wednesday, following a review request from the Biden Administration last year. Reuters reports: The scheduling recommendation for marijuana was provided to the Drug Enforcement Agency (DEA) on Tuesday as part of President Biden's directive to HHS, the spokesperson said. "As part of this process, HHS conducted a scientific and medical evaluation for consideration by DEA. DEA has the final authority to schedule or reschedule a drug under the Controlled Substances Act. DEA will now initiate its review," a DEA spokesperson said.

Marijuana is currently classified as a schedule I drug under the Controlled Substances Act, meaning it has a high potential for abuse and no accepted medical use, along with drugs like heroin and LSD. HHS is recommending reclassifying marijuana to say it has a moderate to low potential for dependence and a lower abuse potential, which would put it in a class with ketamine and testosterone. "If marijuana classification were to ease at the federal level, that could allow major stock exchanges to list businesses that are in the cannabis trade, and potentially allow foreign companies to begin selling their products in the United States," notes Reuters.

While marijuana remains illegal on the federal level, nearly 40 U.S. states have legalized it in some form. According to a survey last year from the Pew Research Center, "an overwhelming share of U.S. adults (88%) say either that marijuana should be legal for medical and recreational use by adults (59%) or that it should be legal for medical use only (30%)."

An anonymous reader quotes a report from Ars Technica: NASA officials sounded an alarm Tuesday about the agency's Deep Space Network, a collection of antennas in California, Spain, and Australia used to maintain contact with missions scattered across the Solar System. Everything from NASA's Artemis missions to the Moon to the Voyager probes in interstellar space rely on the Deep Space Network (DSN) to receive commands and transmit data back to Earth. Suzanne Dodd, who oversees the DSN in her position at NASA's Jet Propulsion Laboratory, likes to highlight the network's importance by showing gorgeous images from missions like the James Webb Space Telescope and the Perseverance rover on Mars. "All these images, and all these great visuals for the public, and all the science for the scientists come down through the Deep Space Network," Dodd said Tuesday in a meeting of the NASA Advisory Council's Science Committee.

But Dodd doesn't take a starry-eyed view of the challenges operating the Deep Space Network. She said there are currently around 40 missions that rely on the DSN's antennas to stay in communication with controllers and scientists back on Earth. Another 40-plus missions will join the roster over the next decade or so, and many of the 40 missions currently using time on the network will likely still be operating over that time. "We have more missions coming than we currently are flying," Dodd said. "We're nearly doubling the load on the DSN. A lot of those are either lunar exploration or Artemis missions, and a lot of Artemis precursor missions with commercial vendors. So the load is increasing, and it's very stressful to us." "It's oversubscribed, yet it's vital to anything the agency wants to do," she said.

Vint Cerf, an Internet pioneer who is now an executive at Google, sits on the committee Dodd met with Tuesday. After hearing from Dodd and other NASA managers, Cerf said: "The deep space communications system is in deep -- well, let me use a better word, deficit. There's a four-letter word that occurs to me, too." Because astronauts are involved, the Artemis missions will come with unique requirements on the DSN. "We're not going to have bits of data. We're going to have gigabits of data," said Philip Baldwin, acting director of the network services division at JPL. "I don't want 1080p for video resolution. I want 8K video." Each of the three stations on the Deep Space Network has a 70-meter (230-foot) dish antenna, the largest antennas in the world for deep space communications. Each location also has at least three 112-foot (34-meter) antennas. The oldest of the large antennas in California entered service in 1966, then was enlarged to its 70-meter diameter in 1988. "We have reached a really critical point on the DSN's aging infrastructure," said Sandra Cauffman, deputy director of NASA's astrophysics division.

Some of the world's leading astronomical observatories have reported cyberattacks that have resulted in temporary shutdowns. Space.com reports: The National Science Foundation's National Optical-Infrared Astronomy Research Laboratory, or NOIRLab, reported that a cybersecurity incident that occurred on Aug. 1 has prompted the lab to temporarily halt operations at its Gemini North Telescope in Hawaii and Gemini South Telescope in Chile. Other, smaller telescopes on Cerro Tololo in Chile were also affected. "Our staff are working with cybersecurity experts to get all the impacted telescopes and our website back online as soon as possible and are encouraged by the progress made thus far," NOIRLab wrote in a statement on its website on Aug. 24.

It's unclear exactly what the nature of the cyberattacks were or from where they originated. NOIRLab points out that because the investigation is still ongoing, the organization will be cautious about what information it shares about the intrusions. The cyberattacks on NOIRLab's facilities occurred just days before the United States National Counterintelligence and Security Center (NCSC) issued a bulletin (PDF) advising American space companies and research organizations about the threat of cyberattacks and espionage.

Foreign spies and hackers "recognize the importance of the commercial space industry to the U.S. economy and national security, including the growing dependence of critical infrastructure on space-based assets," the bulletin stated. "They see US space-related innovation and assets as potential threats as well as valuable opportunities to acquire vital technologies and expertise."

The word "funga" should be used alongside flora and fauna when discussing conservation issues to reflect the importance of fungi to ecosystem health, a UN body has said. From a report: The secretariat of the UN convention on biological diversity (UNCBD) said it was time that fungi were "recognised and protected on an equal footing with animals and plants in legal conservation frameworks."

"Whenever referring to the macroscopic diversity of life on Earth, we should use 'flora, fauna and funga,' and 'animal, plants and fungi,'" it said in an Instagram post. Mycologists, mostly from Latin America, established the term "funga" five years ago. It refers to the levels of diversity of fungi in any given place, and is analogous to "flora and fauna," which refer to plants and animals. Unlike flora and fauna, it is not a Latin term but was chosen because it is morphologically similar. "Just like mycelium, mycologically inclusive language will spread unseen but profound [sic], permeating public consciousness (and policy) to acknowledge fungi's vital role in the grand web of life on and in Earth," it said.

SonicSpike shares a report from NASA: In 2023, NASA is sending a technology demonstration known as the Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T) to the space station. Together, ILLUMA-T and the Laser Communications Relay Demonstration (LCRD), which launched in December 2021, will complete NASA's first two-way, end-to-end laser relay system. With ILLUMA-T, NASA's Space Communications and Navigation (SCaN) program office will demonstrate the power of laser communications from the space station. Using invisible infrared light, laser communications systems send and receive information at higher data rates. With higher data rates, missions can send more images and videos back to Earth in a single transmission. Once installed on the space station, ILLUMA-T will showcase the benefits higher data rates could have for missions in low Earth orbit.

"Laser communications offer missions more flexibility and an expedited way to get data back from space," said Badri Younes, former deputy associate administrator for NASA's SCaN program. "We are integrating this technology on demonstrations near Earth, at the Moon, and in deep space." In addition to higher data rates, laser systems are lighter and use less power -- a key benefit when designing spacecraft. ILLUMA-T is approximately the size of a standard refrigerator and will be secured to an external module on the space station to conduct its demonstration with LCRD. Currently, LCRD is showcasing the benefits of a laser relay in geosynchronous orbit -- 22,000 miles from Earth -- by beaming data between two ground stations and conducting experiments to further refine NASA's laser capabilities. "Once ILLUMA-T is on the space station, the terminal will send high-resolution data, including pictures and videos to LCRD at a rate of 1.2 gigabits-per-second," said Matt Magsamen, deputy project manager for ILLUMA-T. "Then, the data will be sent from LCRD to ground stations in Hawaii and California. This demonstration will show how laser communications can benefit missions in low Earth orbit."

ILLUMA-T is launching as a payload on SpaceX's 29th Commercial Resupply Services mission for NASA. In the first two weeks after its launch, ILLUMA-T will be removed from the Dragon spacecraft's trunk for installation on the station's Japanese Experiment Module-Exposed Facility (JEM-EF), also known as "Kibo" -- meaning "hope" in Japanese. NASA's Laser Communications Roadmap. Following the payload's installation, the ILLUMA-T team will perform preliminary testing and in-orbit checkouts. Once completed, the team will make a pass for the payload's first light -- a critical milestone where the mission transmits its first beam of laser light through its optical telescope to LCRD. Once first light is achieved, data transmission and laser communications experiments will begin and continue throughout the duration of the planned mission.
