Venus’s 6,000-km Wave Explained by the Solar System’s Largest Hydraulic Jump

Researchers show Venus’s colossal 6,000-km atmospheric wave results from the solar system’s largest hydraulic jump: when eastward lower-cloud flows slow abruptly, a strong vertical updraft lifts sulfuric acid vapor and creates a massive cloud disturbance that may help sustain Venus’s superrotation. The finding, based on advanced fluid-dynamics simulations and microphysical modeling, explains why previous Earth-centric models missed the phenomenon and outlines steps to incorporate this mechanism into broader Venus climate models, with potential implications for future Mars research.

ISS Detects Mysterious Phenomenon 55 Miles Above Earth

The International Space Station, using NASA's Atmospheric Wave Instrument (AWE), detected atmospheric waves 55 miles above Earth during Hurricane Helene's impact on Florida. These waves, invisible from the ground, highlight how severe weather can affect the mesosphere, a high atmospheric layer. Such disturbances can influence satellite operations by altering air density, underscoring the interconnectedness of Earth's weather and space conditions. This discovery aids in understanding atmospheric dynamics and improving satellite resilience.

"SpaceX Successfully Launches Falcon 9 CRS-29 Rocket"

SpaceX Falcon 9 CRS-29 is set to launch from Kennedy Space Center's Launch Complex 39A. The mission includes delivering new science investigations, supplies, and equipment to the International Space Station crew. Additionally, experiments will be conducted to study atmospheric gravity waves and test high data rate laser communications from the ISS to Earth. No viewing opportunities will be available for this launch.
