Southwest Research Institute (SwRI) scientists re-examined Voyager 2 data, proposing a space weather event explains the intense radiation belts detected in 1986, solving a nearly four-decade-old planetary science mystery.

The team posits a solar co-rotating interaction region generated the mission's most intense high-frequency waves, which, unlike previous theories, accelerated electrons instead of scattering them into the planet's atmosphere.

This finding resolves a major Voyager 2 anomaly and suggests similar space weather events could shape Neptune's magnetosphere, strengthening the case for a dedicated Uranus orbiter mission, according to SwRI researchers.

The House Science, Space, and Technology Committee advanced a NASA authorization bill that directs the agency to evaluate preserving the International Space Station (ISS) in a stable orbital harbor after 2030.

Deorbiting the 450-ton station requires a 57 m/s velocity change using 10 tons of propellant, while boosting it to a 100-year stable orbit would require over 20 tons of propellant.

According to Rep. Whitesides, the amendment protects a $100B+ asset for future generations, challenging NASA’s deorbit plan as commercial LEO (Low Earth Orbit) destination programs face significant funding and development hurdles.

NASA (National Aeronautics and Space Administration) Goddard researchers analyzed organic compounds from a Curiosity rover sample, concluding non-biological sources alone cannot explain the abundance of molecules found in Gale Crater mudstone.

The team modeled the degradation of decane, undecane, and dodecane over 80 million years of cosmic radiation exposure, calculating a far higher initial concentration than non-biological meteorite delivery could provide.

This analysis, published in Astrobiology, strengthens the hypothesis that biological processes may have formed these compounds, leaving open the possibility that fragments of fatty acids were preserved in ancient Martian rock.

Center for Astrobiology (CAB) researchers used the James Webb Space Telescope (JWST) to uncover an unprecedented richness of organic molecules within the deeply obscured nucleus of galaxy IRAS 07251–0248.

The NIRSpec and MIRI instruments detected benzene, methane, and acetylene, and for the first time outside our galaxy, the methyl radical (CH₃) across a 3–28 micron wavelength observation range.

According to lead author Dr. Ismael García Bernete, the findings suggest cosmic rays fragment carbon-rich grains, turning extreme galactic nuclei into factories for key prebiotic molecules, challenging existing chemical models.

China's space program launched its experimental reusable spaceplane for a fourth time, continuing a highly secretive test program to develop advanced orbital vehicle technologies analogous to the American X-37B spacecraft.

The vehicle launched atop a Long March 2F rocket from the Jiuquan Satellite Launch Center, with previous missions lasting from a few days up to 276 days in low Earth orbit.

This fourth mission highlights China's rapid progress in reusable space systems, which Western analysts believe is critical for developing future military surveillance, rapid response, and on-orbit servicing capabilities for strategic advantage.
