A spacecraft is preparing for a mission to collect about 10 grams of material from Phobos, one of Mars’s two small moons, and bring it back to Earth. The sample-return plan would let researchers examine material with laboratory instruments far more capable than those that can be carried on a spacecraft.

Phobos is a scientific puzzle: its composition may preserve clues to the early Solar System, and researchers continue to investigate whether it formed alongside Mars or is a captured object. A sample could also contain material blasted from Mars by impacts, so even a small amount may offer several lines of evidence. The mission is planned, not a completed collection; launch, landing, sampling and return all carry substantial technical risk. The eventual analysis will matter as much as the flight, with teams needing to establish where each grain came from and how it was altered by space exposure.

Archaeological work in Portugal’s Côa valley is investigating how hunter-gatherers may have seen and understood its extensive Palaeolithic engravings. The site is especially notable for animal figures carved into exposed rock, rather than confined to caves, and excavation is adding context to images that can otherwise be viewed as isolated artworks.

The central question is not only what the animals depict, but how the engravings related to movement, gathering places and the surrounding landscape. Archaeological context can help test interpretations, though it rarely supplies a single definitive explanation for images made thousands of years ago. The findings will need to be assessed alongside dating evidence, the placement of the engravings and other traces of human activity. That careful work can broaden accounts of prehistoric symbolic life without assuming that modern ideas about art or ritual map neatly onto the people who made it.

A new arXiv study describes a flexible wavefront sensor designed for extreme adaptive-optics systems. These systems correct atmospheric distortion and other optical errors in real time, a necessary step for separating the faint light of a planet from the glare of its much brighter host star.

The authors present a differentiable design for a phase-induced-amplitude-apodisation Zernike wavefront sensor and assess how its performance could approach fundamental limits of wavefront measurement. The motivation is practical: better sensing could help observatories correct faster or work with fainter targets, including nearby stars whose habitable-zone planets are challenging to observe directly. This is a research preprint, not evidence that a telescope has already achieved those gains in routine observations. Experimental validation, robustness to real observing conditions and integration with complete adaptive-optics systems will determine how much the proposed design changes what astronomers can detect.

An opinion piece revisits computer scientist Margaret Hamilton’s role in developing software for the Apollo missions, emphasizing the importance of anticipating failures in systems where mistakes have high stakes. The work is often used to illustrate that software engineering is not merely about writing code: it also involves designing for uncertainty and making systems behave safely under pressure.

The item is framed as a farewell, but the supplied snippet is an op-ed rather than an independently detailed obituary, so that wording alone should not be treated as confirmation of a death. The technical legacy it discusses is still relevant: modern spacecraft, medical devices and other critical systems depend on rigorous testing, clear priorities and graceful handling of unexpected conditions. Recalling that history is most useful when it keeps the engineering lessons in view—and recognizes the teams and practices behind complex achievements, not just a single celebrated figure.

A report from central Kalimantan describes wildfire smoke producing a toxic haze that is affecting residents across the region. Smoke pollution can travel well beyond a fire’s edge, leaving communities exposed even when flames are not nearby and making daily life difficult for people with respiratory or cardiovascular vulnerabilities.

The immediate public-health picture depends on measurements that a field report alone cannot provide: pollutant concentrations, how long exposure lasts and which communities face the highest levels. Fine particles in wildfire smoke can penetrate deep into the lungs, while repeated or prolonged exposure raises broader health concerns. The scale and duration of this episode, and the contribution of different land and weather conditions, will need to be established through monitoring and follow-up reporting. Clear air-quality information and timely health guidance are essential as the fires continue, alongside attention to the causes that make landscapes and communities vulnerable to recurring smoke.

On 18 October 1963, a French research programme sent a cat named Félicette on a suborbital rocket flight, making her the first cat to travel to space. The short flight was part of an era when scientists used animals to investigate how living bodies responded to launch and brief exposure to weightlessness before human spaceflight became established.

The milestone is also a reminder that the history of space science includes animal experiments whose costs deserve acknowledgement, not just celebration. Félicette’s flight was not an orbital mission, and describing it precisely helps distinguish it from later human journeys and other animal missions. Today, research ethics and the development of alternative methods shape how such work is assessed. Looking back at the flight can prompt a more complete account of early space exploration: its technical questions, the knowledge it sought and the welfare trade-offs that would be scrutinized differently now.

A citizen-science project is asking volunteers to inspect NASA telescope data for signs of black holes that astronomers have not yet identified. The search focuses on candidates hidden among large datasets, where human pattern-spotting can help researchers flag unusual signals for closer examination.

Black holes are not seen directly; astronomers infer their presence from effects such as the motion of nearby matter or radiation from hot material falling toward them. The galaxy’s “missing” black holes are missing from current catalogues, not proven to be absent, and some may be difficult to detect because they have little nearby material to reveal them. Volunteer classifications can guide follow-up analysis, but candidate signals need independent checks before they become discoveries. The project illustrates how public participation can contribute to data-heavy research while giving scientists a wider pool of eyes to sift through observations.
