### Cosmic Spotlight NASA and Roscosmos are actively addressing cracks that have appeared in modules of the International Space Station. These fissures raise questions about how decades of thermal cycling and micrometeoroid impacts affect the station’s aging structure. Engineers on both sides are analyzing stress patterns and evaluating whether targeted repairs or operational adjustments can extend the outpost’s life. Continued cooperation here is essential because the station remains the only long-duration laboratory in orbit. How long can the current modules remain safe before major refurbishment or replacement becomes necessary? ### Cosmic Deep Dive: The Constant Glow of Earth’s Upper Atmosphere If every square centimeter of the night sky were gathered into a single point, airglow would still outshine the combined light of all visible stars in certain wavelengths. During daylight, solar ultraviolet radiation splits oxygen and nitrogen molecules high above the surface; at night those atoms recombine and release the stored energy as faint photons. This process peaks near 90 kilometers altitude, where temperatures sit around –90 °C and pressures are less than a millionth of sea level. The glow forms a thin, ever-present shell that circles the entire planet, varying in brightness with solar activity, latitude, and even the season. Yet the precise way solar storms translate into airglow intensity still contains surprises that do not match every model prediction. Why do some wavelengths brighten or fade on timescales that current chemistry cannot fully explain? That’s today’s snapshot from the frontiers. Clear skies ahead. |
