Comet 3I/ATLAS “really did arrive with fantastic timing.”

Astronauts Could Live in Structures Made from Moon Rocks
Scientists are testing “mooncrete,” a concrete analogue made from lunar regolith, as a potential material to build structures on the Moon.
Shining a Light on the People Behind Solar Science
A new database provides a comprehensive who’s who of scientists in solar and heliospheric physics research, offering a valuable resource for that community and a model for other fields to follow.
Is Convection Wobbling Venus?
Venus’s rotation axis is not where it should be – but atmospheric torques, not mantle convection, are likely responsible.
Using Lightning-Induced Precipitation to Estimate Electron Belt Decay Times
A long-term study of MeV electron burst events detected in the inner radiation belt and slot region was used to determine the electron belt decay times.
Planet-Eating Stars Hint at Earth’s Ultimate Fate
A sampling of aging Sun-like stars demonstrates that they likely eat their closest planets.
Fungi, Fertilizer, and Feces Could Help Astronauts Grow Plants on the Moon
A new study offers tantalizing evidence that filamentous fungi extending from roots, along with treated astronaut waste, could provide sufficient scaffolding to help plants grow in planetary regolith.
Uranus’s Small Moons Are Dark, Red, and Water-Poor
…Except for Mab, which is even weirder than expected.
Maybe That’s Not Liquid Water on Mars After All
A “very large roll” of a radar instrument offers new insight into a highly reflective area near the Martian south pole.
Sediments Hint at Large Ancient Martian Moon
Regular, alternating layers in Gale Crater may have been deposited as the result of tides raised by a moon at least 18 times the mass of Phobos, a study says.
Speedy Flyby Adds New Organics to Enceladus’s “Primordial Soup”
A new analysis of old Cassini data has also verified past detections of complex organics in Saturn’s E ring, strengthening the chemical ties between the ring and its progenitor.
