Previously Unknown Moon Found in Uranus’s Orbit : James Webb Space Telescope
NASA’s James Webb Space Telescope has identified a previously unknown moon orbiting Uranus, bringing the planet’s total to 29. Designated S/2025 U1, the six-mile-wide object was detected using Webb’s Near-Infrared Camera during a six-hour observation in February. Its nearly circular orbit suggests it formed near its current location, nestled between Ophelia and Bianca. The image reveals the newly discovered object alongside 13 of the planet’s 28 previously known moons. Cordelia, which orbits just inside the outermost ring, remains obscured by ring glare. To balance extreme brightness contrasts, the image combines three data treatments, highlighting atmospheric features, rings, and moons. Observations used NIRCam’s F150W2 filter, spanning 1.0–2.4 microns. (Credit: NASA, ESA, CSA, STScI, M. El Moutamid (SwRI), M. Hedman (University of Idaho))

Microgravity Linked to Elevated Rates of Congestion & Ear Pressure Problems in Astronauts

A new Houston Methodist study has found that 85% of astronauts on the International Space Station between 2000 and 2019 experienced at least one nasal or sinus issue, with 75% reporting congestion. Researchers linked these problems to fluid shifts in microgravity and pressure changes during spacewalks, which also increased risks of barotrauma and Eustachian tube dysfunction. The analysis, covering 754 medical events from 71 astronauts, suggests that even highly fit crews face performance‑impacting respiratory challenges in orbit.

Lead author and chair of the Department of Otolaryngology, Dr. Masayoshi Takashima noted that over‑the‑counter remedies may work differently in space, underscoring the need for targeted treatments. The findings carry implications for future missions, including commercial spaceflight, where participants may have pre‑existing conditions. Preventive screening and minor procedures to improve breathing are proposed as mitigation steps. The study was published on Aug. 5 in the journal Laryngoscope Investigative Otolaryngology.

Water Signature in Devil Comet Suggests Earth’s Water May Have Come From Space

Scientists believe Earth’s water arrived billions of years ago through impacts from comets, asteroids, and meteorites. Recent observations with the ALMA telescope reveal a deuterium-to-hydrogen (D/H) ratio in cometary water that closely matches Earth’s—challenging earlier assumptions and pointing to Halley-type comets as a possible source.

An international team of scientists, using new ALMA observations of comet 12P/Pons-Brooks also known as the Devil Comet, has revealed a deuterium-to-hydrogen (D/H) ratio in its water nearly identical to Earth’s oceans, the lowest ever recorded in a Halley-type comet. This finding strengthens the long-debated theory that comets may have contributed to Earth’s water and possibly its prebiotic chemistry. By mapping both ordinary and heavy water in the comet’s coma, researchers confirmed the gases originated from the nucleus, not secondary processes.

Comet 12P/Pons-Brooks, photographed in March 2024, is a ‘Halley-type’ comet with an orbital period of roughly 71 years and a nucleus approximately 30 km wide.

The study, led by NASA’s Goddard Space Flight Center, combined Atacama Large Millimeter/sub-millimeter Array’s (ALMA), spatial resolution with infrared data from NASA’s IRTF to build a more complete chemical profile. Unlike previous comet measurements that showed mismatched isotopic signatures, this result suggests that at least some Halley-type comets carried water compatible with terrestrial origins. As planetary science increasingly probes the conditions for habitability, such findings offer a rare isotopic fingerprint linking early solar system bodies to Earth’s formative environment—and potentially to the emergence of life itself. The finding was reported in the journal Nature Astronomy.

NASA & Google are Testing an AI Assistant for Spaceflight Medical Support

As space agencies prepare for extended human missions beyond low Earth orbit, autonomous medical support is emerging as a critical infrastructure need. NASA and Google are jointly testing an AI-powered medical assistant designed to help astronauts diagnose and manage health issues during deep-space missions, where communication delays with Earth can reach up to 45 minutes. The Crew Medical Officer Digital Assistant (CMO-DA), a proof-of-concept for an automated Clinical Decision Support System (CDSS), is being trained on spaceflight literature and refined with input from medical professionals.

Early results suggest the system may be able to reliably interpret symptoms and propose treatment options. This initiative aligns with NASA’s Artemis program and broader efforts to reduce reliance on Earth-based intervention. While the technology remains experimental, its potential extends beyond spaceflight—offering possible applications in remote terrestrial environments with limited access to healthcare. The collaboration reflects a growing trend: embedding AI into mission-critical systems to enhance crew autonomy and resilience in extreme conditions.

The ability to deliver reliable, context-aware medical support without real-time human intervention could become essential infrastructure in the near future. The project also raises broader questions about trust, oversight, and the role of AI in high-stakes environments.

19 August, 2025

More than 50 years after its collection, a sealed Apollo 17 lunar sample has revealed evidence of a rare extraterrestrial landslide on the Moon. Researchers at the Natural History Museum and University of Texas used advanced micro-CT scanning to analyze the core, uncovering clasts (rock fragments) that suggest the Light Mantle region was formed by a long runout landslide. The material’s fluid-like behavior and fine coatings indicate internal fragmentation, not surface erosion.

The Light Mantle is a geologically distinct, high-albedo deposit on the Moon, located at the base of the South Massif in the Taurus-Littrow Valley, where Apollo 17 landed in 1972. It stretches roughly 5 kilometers (3.1 miles) across the valley floor and is believed to be the result of a long runout landslide—the only such feature ever sampled directly on the Moon.

What makes the material scientifically intriguing is its fluid-like flow behavior despite the Moon’s lack of atmosphere or water. While the exact trigger remains uncertain, one hypothesis links the event to debris from the Tycho crater impact, which may have struck the South Massif and initiated the slide. This discovery not only deepens understanding of lunar geology but also informs future sample handling protocols under NASA’s Artemis program. The study underscores the value of preserving samples for decades, allowing new technologies to revisit old questions and refine planetary science ahead of renewed human exploration of the Moon. The findings were published in the Journal of Geophysical Research: Planets.

20 August, 2025

South Korea’s K-RadCube satellite has arrived at NASA’s Kennedy Space Center ahead of its scheduled launch aboard Artemis 2, currently planned for early 2026. Developed by the Korea AeroSpace Administration (KASA), the 41-pound cubesat will measure radiation levels across the Van Allen belts using a dosimeter designed to mimic human tissue. The data aims to inform astronaut safety protocols for deep-space missions.

K-RadCube also carries semiconductor components from Samsung Electronics and SK Hynix to assess their resilience in high-radiation environments—an experiment with implications for future lunar and Martian infrastructure. Once Artemis 2’s Orion spacecraft separates from the upper stage, K-RadCube and other international cubesats, including Germany’s TACHELES, will be deployed into high Earth orbit.

To avoid atmospheric re-entry, the UK’s SteamJet Space Systems will provide a water-based propulsion unit for K-RadCube, performing a rare 12-hour burn to raise its perigee, potentially marking a milestone in sustainable orbital maneuvering.

20 August, 2025

An automated coordination system developed by the U.S. National Radio Astronomy Observatory (NRAO) and SpaceX aims to mitigate radio interference from Starlink satellites, a growing challenge for observatories worldwide. The Operational Data Sharing platform transmits telescope schedules and frequency bands to Starlink, and the Starlink Telescope Boresight Avoidance algorithm, in real time, enabling satellites to redirect beams or mute electronics when passing overhead. Initial tests at the Very Large Array in New Mexico have shown promising results, with expansion planned to other facilities.

The initiative responds to escalating concerns as low Earth orbit constellations multiply — from roughly 3,000 satellites in 2019 to over 15,000 today, with projections exceeding 100,000 by 2030. Such growth risks overwhelming protected radio astronomy bands and degrading observations beyond them. While the system could be adapted for other, its broader adoption telescopes and operators remains uncertain. The effort underscores the tension between broadband access expanding global and preserving the radio-quiet conditions essential for deep-space research.

18 August, 2025

Portugal has issued its first license to operate a spaceport, authorizing the Portuguese Atlantic Spaceport Consortium (ASC) to establish a launch center in Malbusca on the island of Santa Maria, Azores. The five‑year permit covers site operations but excludes individual launch approvals, which will require separate licensing and safety reviews. Initial activities are expected to focus on suborbital flights from 2026, with infrastructure also planned to support ESA’s Space Rider reusable vehicle return missions by 2027.

The licensing process, conducted by Autoridade Nacional de Comunicações (ANACOM), Portugal’s national regulatory authority for the communications sector, in coordination with the Portuguese Space Agency and local authorities, is part of the Portugal Space 2030 strategy to position the Azores as a European platform for space access. The site’s mid‑Atlantic location offers strategic advantages for varied orbital inclinations. This move places Portugal among a growing group of European nations developing domestic launch capabilities, alongside projects in Scotland, Norway, and Sweden, reflecting a broader push for diversified access to space.

18 August, 2025

The FAA has closed its investigation into SpaceX’s Starship Flight 9 failure, clearing the way for Flight 10 as early as Aug. 24. Flight 9, launched May 27 from Starbase, ended with the loss of both stages: Super Heavy Booster 14 exploded during a high‑stress descent after a propellant line rupture, while Ship 35 suffered a methane leak traced to a faulty gas diffuser, destabilizing the vehicle and preventing planned in‑space tests. Weeks later, Ship 36 was destroyed in a ground test explosion caused by a damaged nitrogen Composite Overwrapped Pressure Vessel (COPV).

SpaceX has implemented design, inspection, and operational changes, including reduced descent angles, COPV shielding, and new testing protocols. Flight 10 and Flight 11 will conclude the current Starship/Super Heavy design iteration before upgrades aimed at meeting NASA’s Artemis 3 lunar lander schedule in 2027. The repeated upper‑stage losses hint at ongoing technical hurdles as SpaceX works toward fully reusable, reliable heavy‑lift capability.

20 August, 2025

Acting NASA Administrator Sean Duffy has signaled a strategic pivot away from Earth science toward human space exploration, aligning with the administration’s FY 2026 budget proposal that would cut NASA’s science funding by 47% and reduce Earth science by more than half. Speaking on Fox Business, Duffy argued that climate monitoring could be handled by agencies like NOAA, while NASA should focus on missions to the Moon, Mars, and post‑ISS low Earth orbit destinations.

The proposal places nearly 40 active and planned science missions at risk, including long‑term climate data programs such as the Orbiting Carbon Observatory series. While no cancellations have been finalized, “at risk” notices have been issued to some project staff, heightening uncertainty ahead of congressional appropriations in October.

The shift underscores a broader debate over NASA’s role in climate research, with potential implications for global data continuity and the resilience of Earth observation capabilities.

UK Space Agency to Be Integrated into Department for Science, Innovation and Technology by 2026

21 August, 2025

The UK government will merge the UK Space Agency (UKSA) into the Department for Science, Innovation and Technology (DSIT) by April 2026, retaining the UKSA name but integrating policy and delivery teams under direct ministerial oversight. Officials frame the move as a way to cut duplication, improve accountability, and align strategy with execution, while industry leaders caution it could dilute transparency and distract from European funding negotiations.

The merger coincides with regulatory work on Rendezvous and Proximity Operations, a market projected at £2.7 billion by 2031, and the UK’s first active debris removal mission planned for 2028. Analysts note UKSA’s longstanding lack of a clear niche, overlapping with other agencies on licensing and research, and warn structural changes alone will not address chronic underfunding or the absence of a coherent national space program. The outcome will hinge on whether integration delivers sustained investment and strategic focus.

Astronomers studying galaxy JADES‑GS‑z11‑0 have found it contains unexpectedly high levels of oxygen—about 30% of that in present‑day galaxies—despite existing just 400 million years after the Big Bang. Initially estimated at only 100 million years old, refined measurements place it within the era when the first stars and galaxies emerged. The discovery, made with the James Webb Space Telescope (JWST) and followed up by the Atacama Large Millimeter/submillimeter Array (ALMA), suggests multiple generations of massive stars had already lived and died, enriching the galaxy’s gas with heavy elements far earlier than models predict.

JADES‑GS‑z11‑0 is also forming stars at a rate several times higher than the Milky Way, making it unusually active for its epoch. The rapid buildup of oxygen, carbon, and silicon raises questions about how quickly the conditions for rocky planets—and potentially life—could have arisen. While the finding does not overturn current cosmology, it challenges timelines for early chemical evolution and underscores the need for further high‑resolution studies of the universe’s first billion years. The findings were reported in a preprint paper submitted to the Open Journal of Astrophysics.

Astronomers have demonstrated a rapid‑response method to capture some of the earliest spectra of supernovae, the explosive death of a star, aiming for observations within 24–48 hours of “first light.” Led by Lluís Galbany of the Institute of Space Sciences (ICE‑CSIC) in Barcelona, the pilot study used the Gran Telescopio de Canarias and modern wide‑field surveys to identify candidates absent in previous night’s images but located within galaxies. Early‑phase data are critical for distinguishing between thermonuclear supernovae—originating from white dwarfs in binary systems—and core‑collapse events from massive stars exhausting nuclear fuel.

The team observed ten supernovae, half of each type, most within six days of explosion, two within 48 hours. Early spectra, combined with photometry from facilities such as the Zwicky Transient Facility in California (ZTF) and Asteroid Terrestrial‑impact Last Alert System in Hawaii (ATLAS), provided insights into progenitor systems (the original star (or stars) that eventually produce a transient event like a supernova) and explosion mechanisms. The results suggest coordinated spectroscopic and photometric efforts could soon deliver routine sub‑day observations, supporting next‑generation surveys like LS4 and LSST in probing the universe’s most transient stellar deaths. The study was published on Aug. 19 in the Journal of Cosmology and Astroparticle Physics.

An international team of astronomers has precisely traced one of the brightest fast radio bursts (FRBs) ever recorded—FRB 20250316A—to a compact region in the outskirts of galaxy NGC 4141, about 130 million light-years away. Detected in March by Canada’s CHIME/FRB telescope and localized using its new continent-spanning “outrigger” array, the burst’s position was narrowed to within 45 light-years, enabling follow-up with the James Webb Space Telescope. JWST imaging revealed an unexpected near-infrared source at the site, dubbed NIR-1, that is likely a red giant star or possibly a middle-aged massive star, raising questions about whether it is a stellar object or a transient light echo.

“The precision of this localization, tens of milliarcseconds, is like spotting a quarter from 100 kilometres away.”

Amanda Cook, Study Lead, McGill-based Postdoctoral Researcher.

The event, nicknamed “RBFLOAT,” for Radio Brightest FLash Of All Time, challenges prevailing assumptions: despite its extreme brightness, no repeat signals have been detected over six years of monitoring, prompting renewed consideration of more explosive, non-repeating FRB models.

The outrigger network—antenna clusters positioned thousands of kilometers apart—gives the Canadian Hydrogen Intensity Mapping Experiment. or CHIME, the interferometric baseline needed to pinpoint even fleeting, one-off FRBs with unprecedented accuracy. Researchers say the ability to pinpoint even single bursts with such precision marks a turning point, offering a new pathway to investigate the environments and mechanisms behind these millisecond cosmic flashes. Two papers regarding the discovery of RBFLOAT have been published in The Astrophysical Journal Letters.

How much smaller has Mercury become over time?

New research refines long‑standing uncertainty over Mercury’s gradual contraction as it cools from its formation 4.5 billion years ago. The planet’s surface bears thrust faults—fractures where crustal blocks have been pushed over one another—interpreted as evidence of this shrinkage. Earlier estimates, based on fault length and relief, ranged widely from 1 km to 7 km of radial loss, partly due to variations in fault datasets.

A study by planetary geologists, Stephan R. Loveless, Christian Klimczak, introduces a method that scales shrinkage from the displacement of the largest fault, reducing dependence on dataset size. Applying it to three fault inventories—from 100 to nearly 6,000 features—yielded consistent results of 2–3.5 km contraction from faulting. When combined with other cooling‑related processes, total shrinkage since formation is estimated at 2.7–5.6 km.

Beyond Mercury, the approach could inform tectonic analyses of other fault‑scarred worlds, such as Mars, offering a more stable metric for reconstructing planetary thermal and geological histories. The findings were published in AGU Advances.
