University of Oxford researchers analyzed seismic data from NASA's InSight lander to investigate potential magma reservoirs beneath the Martian surface, building on previous studies of the planet's interior structure.

InSight's seismometer detected low-velocity zones in the upper mantle consistent with partial melt regions at depths between 200 and 400 kilometers, suggesting temperatures sufficient to maintain liquid rock beneath volcanic provinces like Elysium Planitia.

These findings challenge assumptions that Mars became geologically dormant billions of years ago, according to the Oxford team, potentially reshaping models of planetary thermal evolution and future landing site selection.

Planetary scientists submitted new theoretical models examining the internal structure of ice giants Uranus and Neptune, proposing that extreme pressures create unexpected thermal conditions beneath their visible cloud layers.

The models predict silicate magma oceans at 7,000 Kelvin existing beneath ionic water layers at pressures exceeding 200 gigapascals, fundamentally different from traditional three-layer interior models of these distant worlds.

This reinterpretation could explain magnetic field anomalies observed by Voyager 2 and may influence planning for proposed ice giant flagship missions, according to the study authors.

CNSA (China National Space Administration) scientists published Tianwen-3 mission details in Nature Astronomy, outlining China's ambitious plan to execute the first successful Mars sample-return mission before NASA's competing effort.

The mission architecture includes two-meter subsurface drilling capability, drone-assisted sampling within several hundred meters of the lander, and collection of at least 500 grams of Martian material for Earth return around 2031.

Tianwen-3 could deliver the first physical Mars samples to terrestrial laboratories, enabling electron microscope and mass spectrometer analysis impossible with rover-based instruments, according to mission planners.

NASA and Katalyst Space prepared the LINK robotic servicing satellite to rescue the Neil Gehrels Swift Observatory from atmospheric reentry, demonstrating commercial satellite servicing capabilities on a spacecraft never designed for orbital maintenance.

The 880-pound LINK spacecraft carries three ion thrusters and robotic arms to grapple Swift and raise its altitude from approximately 185 miles to nearly 370 miles over several months following the Pegasus XL launch.

This high-risk mission could establish a blueprint for extending spacecraft lifetimes cost-effectively, according to Katalyst CEO Ghonhee Lee, advancing the commercial satellite servicing industry for future orbital infrastructure.

Kanazawa University Associate Professor Kimihiko Nakajima led an international team using JWST (James Webb Space Telescope) to characterize LAP1-B, an ultra-faint galaxy from 13 billion years ago magnified 100 times by gravitational lensing.

NIRSpec spectroscopy over 30 hours revealed oxygen abundance just 1/240th solar levels combined with elevated carbon-to-oxygen ratios matching theoretical predictions for material dispersed by first-generation stellar explosions in the early universe.

LAP1-B appears to be the long-sought ancestor of Ultra-Faint Dwarf galaxies near the Milky Way, according to Professor Masami Ouchi, solving mysteries about how these cosmic fossils survived to the present day.
