Chinese Astronauts May Build a Base Inside a Lunar Lava Tube (universetoday.com) 75

According to Universe Today, China may utilize lunar caves as potential habitats for astronauts on the Moon, offering defense against hazards like radiation, meteorites, and temperature variations. From the report: Different teams of scientists from different countries and agencies have studied the idea of using lava tubes as shelter. At a recent conference in China, Zhang Chongfeng from the Shanghai Academy of Spaceflight Technology presented a study into the underground world of lava tubes. Chinese researchers did fieldwork in Chinese lava tubes to understand how to use them on the Moon. According to Zhang, there's enough similarity between lunar and Earthly lava tubes for one to be an analogue of the other. It starts with their two types of entrances, vertical and sloped. Both worlds have both types.

Most of what we've found on the Moon are vertical-opening tubes, but that may be because of our overhead view. The openings are called skylights, where the ceiling has collapsed and left a debris accumulation on the floor of the tube directly below it. Entering through these requires either flight or some type of vertical lift equipment. Sloped entrances make entry and exit much easier. It's possible that rovers could simply drive into them, though some debris would probably need to be cleared. According to Zhang, this is the preferred entrance that makes exploration easier. China is prioritizing lunar lava tubes at Mare Tranquillitatis (Sea of Tranquility) and Mare Fecunditatis (Sea of Fecundity) for exploration.

China is planning a robotic system that can explore caves like the one in Mare Tranquillitatis. The primary probe will have either wheels or feet and will be built to adapt to challenging terrain and to overcome obstacles. It'll also have a scientific payload. Auxiliary vehicles can separate from the main probe to perform more reconnaissance and help with communications and "energy support." They could be diversified so the mission can meet different challenges. They might include multi-legged crawling probes, rolling probes, and even bouncing probes. These auxiliary vehicles would also have science instruments to study the lunar dust, radiation, and the presence of water ice in the tubes. China is also planning a flight-capable robot that could find its way through lava tubes autonomously using microwave and laser radars.
"China's future plan, after successful exploration, is a crewed base," the report adds. "It would be a long-term underground research base in one of the lunar lava tubes, with a support center for energy and communication at the tube's entrance. The terrain would be landscaped, and the base would include both residential and research facilities inside the tube."

"[R]egardless of when they start, China seems committed to the idea. Ding Lieyun, a top scientist at Huazhong University of Science and Technology, told the China Science Daily that 'Eventually, building habitation beyond the Earth is essential not only for all humanity's quest for space exploration but also for China's strategic needs as a space power.'"

After Seven Years, Sample Collected From Asteroid Finally Returns to Earth (nasa.gov) 34

OSIRIS-REx weighs 4,650 pounds (or 2,110 kg). On September 8th of 2016, NASA first launched the spacecraft on its 3.8-billion mile mission to land on an asteroid and retrieve a sample.

That sample has just returned.

Throughout Sunday morning, NASA tweeted historic updates from the sample's landing site in Utah. "We've spotted the #OSIRISREx capsule on the ground," they announced about 80 minutes ago (including a 23-second video clip). "The parachute has separated, and the helicopters are arriving at the site. We're ready to recover that sample!"

UPI notes that the capsule "reached temperatures up to 5,000 degrees Fahrenheit during reentry, so protective masks and gloves are required to handle it," describing its payload as "a 250-gram dust sample."

15 minutes later NASA shared footage of "the first persons to come into contact with this hardware since it was on the other side of the solar system." A recovery team approached the capsule to perform an environmental safety sweep confirming there were no hazardous gas.

"The impossible became possible," NASA administrator Bill Nelson said in a statement. The Guardian reports he confirmed the capsule "brought something extraordinary — the largest asteroid sample ever received on Earth.

"It's going to help scientists investigate planet formation, it's going to improve our understanding of the asteroids that could possibly impact the earth and it will deepen our understanding of the origin of our solar system and its formation."

"This mission proves that NASA does big things, things that have inspired us, things that unite us...

"The mission continues with incredible science and analysis to come. But I want to thank you all, for everybody that made this Osiris-Rex mission possible."

Professor Neil Bowles of the University of Oxford, one of the scientists who will study the sample, told the Guardian that he was excited to see the sample heading to the clean room at Johnson Space Center. "So much new science to come!"

And that 4,650-pound spacecraft is still hurtling through space. 20 minutes after delivering its sample, the craft " fired its engines to divert past Earth toward its new mission to asteroid Apophis," NASA reports. The name of its new mission? OSIRIS-APEX. Roughly 1,000 feet wide, Apophis will come within 20,000 miles of Earth — less than one-tenth the distance between Earth and the Moon — in 2029. OSIRIS-APEX is scheduled to enter orbit of Apophis soon after the asteroid's close approach of Earth to see how the encounter affected the asteroid's orbit, spin rate, and surface.

India's Moon Lander Has Not Replied to Its First Wake-Up Call (nytimes.com) 34

"As the sun rose on Friday over the lunar plateau where India's Vikram lander and Pragyan rover sit, the robotic explorers remained silent," writes the New York Times: The Indian Space Research Organization, India's equivalent of NASA, said on Friday that mission controllers on the ground had sent a wake-up message to Vikram. The lander, as expected, did not reply. Efforts will continue over the next few days, but this could well be the conclusion of Chandrayaan-3, India's first successful space mission to the surface of another world...

The hope was that when sunlight again warmed the solar panels, the spacecraft would recharge and revive. But that was wishful thinking. Neither Vikram nor Pragyan were designed to survive a long, frigid lunar night when temperatures plunge to more than a hundred degrees below zero, far colder than the electronic components were designed for. The spacecraft designers could have added heaters or used more resilient components, but that would have added cost, weight and complexity...

The mission's science observations included a temperature probe deployed from Vikram that pushed into the lunar soil. The probe recorded a sharp drop, from about 120 degrees Fahrenheit at the surface to 10 degrees just three inches down. Lunar soil is a poor conductor of heat. The poor heat conduction could be a boon for future astronauts; an underground outpost would be well-insulated from the enormous temperature swings at the surface. Another instrument on Vikram, a seismometer, detected on Aug. 26 what appeared to be a moonquake... The Pragyan measurement suggests that concentrations of sulfur might be higher in the polar regions. Sulfur is a useful element in technologies like solar cells and batteries, as well as in fertilizer and concrete.

Before it went to sleep earlier this month, Vikram made a small final move, firing its engines to rise about 16 inches above the surface before softly landing again. The hop shifted Vikram's position by 12 to 16 inches, ISRO said. "Hoping for a successful awakening for another set of assignments!" ISRO posted on X, the social network formerly known as Twitter, on Sept. 2. "Else, it will forever stay there as India's lunar ambassador."

"Efforts to establish contact will continue," ISRO tweeted yesterday...

NASA's Webb Finds Carbon Source on Surface of Jupiter's Moon Europa 26

NASA, in a press release: Jupiter's moon Europa is one of a handful of worlds in our solar system that could potentially harbor conditions suitable for life. Previous research has shown that beneath its water-ice crust lies a salty ocean of liquid water with a rocky seafloor. However, planetary scientists had not confirmed if that ocean contained the chemicals needed for life, particularly carbon. Astronomers using data from NASA's James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Europa.

Analysis indicates that this carbon likely originated in the subsurface ocean and was not delivered by meteorites or other external sources. Moreover, it was deposited on a geologically recent timescale. This discovery has important implications for the potential habitability of Europa's ocean. "On Earth, life likes chemical diversity -- the more diversity, the better. We're carbon-based life. Understanding the chemistry of Europa's ocean will help us determine whether it's hostile to life as we know it, or if it might be a good place for life," said Geronimo Villanueva of NASA's Goddard Space Flight Center in Greenbelt, Maryland, lead author of one of two independent papers describing the findings. "We now think that we have observational evidence that the carbon we see on Europa's surface came from the ocean. That's not a trivial thing. Carbon is a biologically essential element," added Samantha Trumbo of Cornell University in Ithaca, New York, lead author of the second paper analyzing these data. NASA plans to launch its Europa Clipper spacecraft, which will perform dozens of close flybys of Europa to further investigate whether it could have conditions suitable for life, in October 2024.

Maduro Says Venezuela Will Send Astronauts To Moon In Chinese Spaceship (washingtonpost.com) 151

An anonymous reader quotes a report from the Washington Post: Venezuelan President Nicolas Maduro vowed to send "the first Venezuelan man or woman to the moon" in a Chinese spacecraft as part of a new strategic partnership between the two countries, he said Wednesday during a state visit to Beijing. Maduro and Chinese President Xi Jinping, meeting in person for the first time in five years, agreed to boost cooperation in several areas, Maduro said, including oil, trade, finance, mining -- and space exploration.

"Very soon, Venezuelan youth will come to prepare as astronauts, here in Chinese schools," Maduro said, as part of a "new era" of collaboration between China and Venezuela. After years of drifting away from Beijing, Maduro is strengthening ties with China as he seeks help reviving Venezuela's crumbling economy and oil industry. Venezuela is also in talks with the United States exploring the possibility of lifting some U.S. sanctions on Venezuela's oil sector in exchange for Maduro's promise to hold free and fair presidential elections next year.
"Venezuela became the first outside nation to join the International Lunar Research Station (ILRS) project, which was jointly announced by China and Russia in 2021," notes Space.com.

It may be some time before any Venezuelans visit the moon, however. The report notes that Venezuela owes over $15 billion to China at the moment, which will likely impact how much the country would be able to contribute to the China-led ILRS. Venezuela also faces severe economic, political and social crises that have fueled an exodus that has surpassed 7 million.

Avi Loeb Says Meteor Analysis Shows It Originated Outside Our Solar System (usatoday.com) 86

In late August the blog of Harvard professor Avi Loeb declared he had "Wonderful news! For the first time in history, scientists analyzed materials from a meter-size object that originated from outside the solar system."

In July Loeb retrieved parts of a meteor that landed in the waters off of Papua, New Guinea in 2014. A local New York newscast describes the find as "metallic marbles, less than a millimeter in diameter," while Loeb called them "beautiful spheres that were colored — blue, brown or gold."

Now USA Today reports: Early analysis shows that some spherules from the meteor path contain "extremely high abundances" of an unheard-of composition of heavy elements. Researchers on the team say the composition of beryllium, lanthanum and uranium, labeled as a "BeLaU" composition, does not match terrestrial alloys natural to Earth or fallout from nuclear explosions. Additionally, the composition is not found in magma oceans of Earth, nor the moon, Mars or other natural bodies in the solar system.

Other elements are thought to have been lost by evaporation during IM1's passage through the Earth's atmosphere, researchers said, leading them to theorize that the spherules could originate in a magma ocean on an exoplanet with an iron core outside the solar system.

Long-time Slashdot reader Okian Warrior writes that "Technical details can be found here, and a readable accounting of the analysis and results can be found on Avi Loeb's blog." Loeb writes that the exact composition of those spheres are now being studied at three separate laboratories, including one at Harvard.

In July the New York Times published reactions to Loeb's claim that "It's most likely a technological gadget with artificial intelligence." "People are sick of hearing about Avi Loeb's wild claims," said Steve Desch, an astrophysicist at Arizona State University. "It's polluting good science — conflating the good science we do with this ridiculous sensationalism and sucking all the oxygen out of the room." Dr. Desch added that several of his colleagues were now refusing to engage with Dr. Loeb's work in peer review, the process by which scholars evaluate one another's research to ensure that only high-quality studies are published... "What the public is seeing in Loeb is not how science works. And they shouldn't go away thinking that."
Last week Salon also had a few questions for Loeb: In your book, you called Carl Sagan's adage that "extraordinary claims require extraordinary evidence" a "logical fallacy." How and why do you think that statement is somewhat flawed or a logical fallacy?

It's used as an excuse for people who don't want to deal with an exciting possibility. They don't seek the evidence and they argue, "Well, we don't have any evidence...."

If or when we encounter extraterrestrial life, do you think we'll find it or it will find us? Why?

I think we will find it near us because most stars [formed] billions of years before the sun, so it's more likely that some other civilizations preceded us because their star, if it's like the sun, already went through what we in the future might go through. We just need to be humble and modest, not assume that we are unique and special — that Albert Einstein was the smartest scientist who ever lived since the Big Bang — and engage in the search.

That's what I'm trying to do, and the pushback is really strange under these circumstances because the people who argue against it have very strong opinions. But if you look at the history of science, they were very often wrong: the people [who] thought that the earth was the center of the universe, for example.

From Loeb's blog post: During my routine jog at sunrise on the deck of Silver Star, I was asked: "Are you running away from something or towards something?" My answer was: "Both. I am running away from colleagues who have strong opinions without seeking evidence, and I am running towards a higher intelligence in interstellar space."

Abandoned Apollo 17 Lunar Module Is Causing Tremors On the Moon (cnn.com) 28

A spacecraft left behind by U.S. astronauts on the lunar surface could be causing small tremors known as moonquakes, according to a new study. CNN reports: Researchers revealed the previously unknown form of seismic activity on the moon for the first time through an analysis of Apollo-era data using modern algorithms. Massive temperature swings that occur on the moon can cause human-made structures to expand and contract in a way that produces these vibrations, the report suggests. The lunar surface is an extreme environment, oscillating between minus 208 degrees Fahrenheit (minus 133 degrees Celsius) in the dark and 250 degrees Fahrenheit (121 degrees Celsius) in direct sun, according to a news release about the study.

In fact, the entire surface of the moon expands and contracts in the cold and heat, noted the study published September 5 in the Journal of Geophysical Research: Planets. Yet scientists were able to use a form of artificial intelligence to gain such an intimate understanding of the Apollo-era data that they could pinpoint gentle tremors that emitted from an Apollo 17 lunar lander module sitting a few hundred yards away from instruments recording the moonquakes, according to a synopsis of the study, which was led by Francesco Civilini, a recent California Institute of Technology postdoctoral researcher and a research space scientist at NASA Goddard Space Flight Center. (NASA provided funding for the study.)

The analysis offers new insights into how the moon responds to its surroundings and what can affect its seismic activities. The rumbles were not dangerous and likely would be imperceptible to humans standing on the moon's surface.

Can Japan's H2-A Rocket Deliver a Precision-Lander to the Moon? (msn.com) 9

The Washington Post reports: Japan launched a lunar mission Thursday, overcoming multiple failures and delays to become the fifth country to head to the moon — just weeks after India — in a global race to better understand Earth's closest neighbor... It is scheduled to enter the moon's orbit in three to four months and land early next year.

The rocket is carrying two space missions: a new X-ray telescope to help scientists better understand the origins of the universe and a lightweight high-precision moon lander that will serve as the basis for future moon landing technology. The telescope separated at 8:56 a.m., and the moon lander separated at 9:29 a.m...

Japan has made several attempts to reach the moon, including its Omotenashi project to land an ultrasmall probe. In November, Japan abandoned the project after failing to restore communications with the spacecraft. Earlier this year, Tokyo-based space company ispace also pulled the plug on the first Japanese private-sector attempt to land on the moon.

Japan's high-precision lander hopes to land within 328 feet (100 meters) of its target — which the article says it "much closer than conventional lunar landers, which usually have an accuracy of several kilometers."

NASA Admits 'At Current Cost Levels,' Its SLS Program is Unsustainable (arstechnica.com) 112

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."

Sony Sends Copyright Notices To TV Museum About Shows 40 To 60 Years Old (torrentfreak.com) 61

An anonymous reader quotes a report from TorrentFreak: Rick Klein and his team have been preserving TV adverts, forgotten tapes, and decades-old TV programming for years. Now operating as a 501(c)(3) non-profit, the Museum of Classic Chicago Television has called YouTube home since 2007. However, copyright notices sent on behalf of Sony, protecting TV shows between 40 and 60 years old, could shut down the project in 48 hours. "Our YouTube channel with 150k subscribers is in danger of being terminated by September 6th if I don't find a way to resolve these copyright claims that Markscan made," Klein told TorrentFreak on Friday. "At this point, I don't even care if they were issued under authorization by Sony or not -- I just need to reach a live human being to try to resolve this without copyright strikes. I am willing to remove the material manually to get the strikes reversed."

Over the weekend Klein shared details of the copyright complaints filed with YouTube. Two of the claims can be seen in the image below and on first view, appear straightforward enough. Two episodes of the TV series Bewitched dated 1964 aired on ABC Network and almost sixty years later, archive copies of those transmissions were removed from YouTube for violating Sony copyrights, with MCCTv receiving a strike. A claim targeting an upload titled Bewitched -- 'Twitch or Treat' -- WPWR Channel 60 (Complete Broadcast, 8/6/1984) follows the same pattern, but what isn't shown are the details added by MCCTv to place the episode (and the included commercials) in historical context. Another takedown target -- Bewitched -- 'Sam in the Moon' (Complete 16mm Network Print, 1/5/1967) is accompanied by even more detail, including references in the episode to then-current events.

Given that copyright law locks content down for decades, Klein understands that can sometimes cause issues, although 16 years on YouTube suggests that the overwhelming majority of rightsholders don't consider his channel a threat. If they did, the option to monetize the recordings can be an option. [...] Klein says MCCTv certainly doesn't set out to hurt copyright holders. However, there's always a balance between preserving "rare pieces of video ephemera" and the likelihood that nobody needs to enforce any rights, versus unusual circumstances like these where unexpected complaints need to be resolved with impossible-to-reach parties. Klein says the team is happy to comply with Sony's wishes and they hope that given a little leeway, the project won't be consigned to history. Perhaps Sony will recall the importance of time-shifting while understanding that time itself is running out for The Museum of Classic Chicago Television.

Mission Accomplished, India Puts Moon Rover to 'Sleep' for 14 Days (reuters.com) 34

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.

India Seeks To Top Its Moon Landing with Spacecraft To Study Sun (bloomberg.com) 18

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.

Starfield's 1,000 Planets May Be One Giant Leap for Game Design 106

The stakes are high for Bethesda's newest role-playing game. Microsoft needs an Xbox hit, and players are hungry for an expansive and satisfying space adventure. From a report: Starfield almost immediately nudges its players to the edges of the cosmos. In the opening hours of the role-playing video game, it's possible to land your spaceship on Earth's moon or zip 16 light-years to Alpha Centauri. When you open your map and zoom out from a planet, you can behold its surrounding solar system; zoom out again, and you're scrolling past luminous stars and the mysterious worlds that orbit them. That sprawling celestial journey within Starfield, developed by Bethesda Game Studios, reveals both the tremendous potential and the monumental challenge of an open-world space adventure. Bethesda has hyped an expansive single-player campaign with 1,000 explorable planets. And expectations around the game, officially releasing on Sept. 6 after a 10-month delay, are nearly as vast.

It's the first new universe in 25 years for Bethesda, known for the Elder Scrolls and Fallout series. It's also a high-stakes moment for Microsoft, which makes the Xbox and has long faced criticism that it produces fewer hit games than its console rivals, Sony and Nintendo. To compete, Microsoft went on a spending spree, acquiring Bethesda's parent company in 2020 and agreeing to purchase Activision Blizzard in 2022, a $69 billion bet that is being challenged by regulators. Now Bethesda must deliver. Known for letting players navigate competing factions and undertake eccentric quests, the studio hopes Starfield will dazzle those clamoring for engaging encounters with alien life-forms or space mercenaries as well as a sense of boundless exploration.

NASA Officials Sound Alarm Over Future of the Deep Space Network (arstechnica.com) 49

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.

NASA To Demonstrate Laser Communications From Space Station (nasa.gov) 40

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.

India Becomes the First Country To Land Spacecraft on Moon's South Pole 111

India has become the first country to land a spacecraft on the moon's south pole. It launched Chandrayaan-3 in mid-July, with the spacecraft entering the moon's orbit on Aug. 5. Earlier this week, Russia crashed its Luna-25 rocket in the same lunar region. From a report: It's notoriously difficult to land a rover on the moon. Russia's Luna-25 crashed while making an attempt just this week, while Japanese company ispace failed to land an unmanned lander in April.â 1 Since the moon has no atmosphere, landers can't just softly touch down on the lunar surface. And, without GPS capabilities, scientists rely on the lander's computers to accurately identify where the spacecraft will touch down. India is only the fourth country to pull off a moon landing, behind the U.S., China, and Russia. The nation's lunar aspirations are part of a push by Prime Minister Narendra Modi to garner investments for private space exploration and satellite launches. Speaking at the rocket's launch in July, Modi heralded a "new chapter" in India's space program.

For the First Time, China's Lunar Rover Maps 1,000 Feet Below the Moon's Dark Side (livescience.com) 32

LiveScience brings an update on China's Chang'e-4 — the first spacecraft to ever land on the far side of the moon.

Its Lunar Penetrating Radar has now mapped the lunar subsurface "in finer detail than ever before" by bouncing radio signals deep underground: Their results, which were published Aug. 7 in the Journal of Geophysical Research: Planets, reveal billions of years of previously hidden lunar history. These new data suggest the top 130 feet of the lunar surface are made up of multiple layers of dust, soil, and broken rocks, said lead study author Jianqing Feng, an astrogeological researcher at the Planetary Science Institute in Tucson, Arizona... Farther down, the scientists discovered five distinct layers of lunar lava that seeped across the landscape billions of years ago.

Scientists think our moon formed 4.51 billion years ago, not long after the solar system itself, when a Mars-size object slammed into Earth and broke off a chunk of our planet The moon then continued to be bombarded by objects from space for roughly 200 million years. Some impacts cracked the moon's surface. Like Earth, the moon's mantle at that time contained pockets of molten material called magma, which seeped out through the newly formed cracks in a series of volcanic eruptions, Feng said.

The new data from Chang'e-4 shows that process slowing down over time: Feng and his colleagues found that the layers of volcanic rock grew thinner the closer they were to the moon's surface. This suggests that less lava flowed in later eruptions compared with earlier ones. "[The moon] was slowly cooling down and running out of steam in its later volcanic stage," Feng said. "Its energy became weak over time...."

However, there could still be magma deep underneath the lunar surface, Feng said.

Russia's First Lunar Mission in Decades Crashes Into the Moon (cnn.com) 179

"Russia's first lunar mission in decades has ended in failure with its Luna 25 spacecraft crashing into the moon's surface," reports CNN: The incident, a blow to Russia's space ambitions, happened after communication with the robotic spacecraft was interrupted, a blow to Russia's space ambitions. Russia's space agency, Roscosmos, said it lost touch with Luna 25 on Saturday around 2:57 p.m. Moscow time... According to a "preliminary analysis," Luna-25 "switched to an off-design orbit" before the collision, Roscosmos said. It was not immediately clear what caused the crash... The news comes a day after the spacecraft reported an "emergency situation" as it was trying to enter a pre-landing orbit, according to Roscosmos...

The spacecraft was meant to complete Russia's first lunar landing mission in 47 years. The country's last lunar lander, Luna 24, landed on the surface of the moon on August 18, 1976... Luna 25 was seen as a proving ground for future robotic lunar exploration missions by Roscosmos. Several future Luna spacecraft were slated to make use of the same design. If it had been successful, Luna 25 would have marked a huge stride for the country's civil space program — which some experts say has faced issues for decades — and demonstrate that it could still perform in high-profile, high-stakes missions. "They were having a lot of problems with quality control, corruption, with funding," said Victoria Samson, the Washington office director for Secure World Foundation, a nonprofit that promotes the peaceful exploration of outer space, during an interview Friday.

News that Russia experienced issues with its spacecraft elicited sympathy that reverberated throughout the space community. Thomas Zurbuchen, NASA's former head of science, said in a social media post that no one in the industry "wishes bad onto other explorers... We are reminded that landing on any celestial object is anything but easy & straightforward," he said,

Russia's Luna 25 Mission Launches To the Moon (cnn.com) 60

Russia has successfully launched Luna 25, the country's first lunar lander in 47 years. From a report: The uncrewed spacecraft lifted off from the Vostochny Cosmodrome in Amur Oblast, Russia. Hitching a ride aboard a Soyuz-2 Fregat rocket, Luna 25 took flight at 8:10 a.m. local time Friday, or 7:10 p.m. ET Thursday. Residents of a Russian village were temporarily evacuated Friday morning since there is a "one in a million chance" that one of Luna 25's rocket stages could fall there, according to Reuters.

The spacecraft is expected to first enter an orbit around Earth before transferring to a lunar orbit and ultimately descending to the surface of the moon. Russia's last lunar lander, Luna 24, landed on the moon on August 18, 1976. Luna 25 and India's Chandrayaan-3 mission, which launched in mid-July, are both expected to land at the lunar south pole on August 23, and it's a race to see which country will land first, according to Reuters. But Roscomos said the two missions are not expected to cause a problem for each other because their specific landing zones differ, Reuters reported.

Russia Hopes For Its First Successful Lunar Landing Mission in Nearly 50 Years (theguardian.com) 143

Russia hopes to launch its first successful lunar landing mission for nearly 50 years, with a long-delayed takeoff from the far east of the country scheduled for early on Friday morning that the Kremlin aims to tout as a new achievement in space exploration. From a report: The Luna-25 mission will seek to land near the south pole of the moon, collecting geological samples from the area, and sending back data for signs of water or its building blocks, which could raise the possibility of a future human colony on the moon. But the more immediate goal is to prove that Russia still can launch a lunar landing mission after numerous failures in the past, generations of turnover among its scientific experts, delays due to sanctions and now isolation due to its war in Ukraine.

Post-Soviet Russia has launched two failed space landing missions, the Mars-96 in 1996 and Phobos-Grunt in 2011, both of which crash-landed into the Pacific Ocean. "The Russian Federation hasn't had much luck with launching unmanned interplanetary probes," said Vitaly Egorov, a blogger who writes extensively on space exploration. "Now 12 years later they're launching Luna-25 and the main intrigue is whether or not it will succeed in reaching [the moon] or not, and if it does, can it actually land there? "One of the main goals is to let modern specialists put down space probes softly on celestial objects. They haven't had that experience in 47 years. That knowledge needs to be restored for new specialists on a new technological level."
