NASA has directed Crew-12 members to assume a Safe Haven posture in the SpaceX Crew Dragon while Roscosmos conducts an extended repair on persistent air leaks in the Zvezda module. The operation follows earlier leaks that have troubled the aging station since 2019, with assessments focusing on microscopic cracks and corrosion. Crews are returning to normal operations after measurements are completed.
Recent studies show California’s San Andreas and San Jacinto faults are under stress at levels not seen in a millennium, raising the risk of a large, multi-fault rupture. Cajon Pass could act as a bridge or barrier, and preparedness measures are urged as hazard models improve with physics-based simulations.
The FAA has moved to replace its 1973 ban on overland supersonic flights with new, noise-based standards. Initial proposals could allow faster cross-country travel and reduce flight times, while NASA tests aim to refine how sonic booms are perceived. Final rules are targeted for mid-2027.
Scientists have confirmed Colobus congoensis, known locally as Likweli, as a distinct African monkey species. Found in the Lomami-Lualaba interfluve in eastern Democratic Republic of Congo, it is among the rarest African monkey discoveries in 75 years and may be endangered due to habitat loss and hunting.
