Scientists report that Saturn’s south polar vortex hosts a decagon-shaped pattern, a ten-sided figure distinct from the north pole’s hexagon. Based on observations summarized in Science Advances, the decagon is likely caused by a meandering atmospheric wave rather than a jet stream, offering a striking example of fluid dynamics on a gas giant.
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.
NASA's sensors on the International Space Station detected a previously unknown atmospheric phenomenon, called atmospheric waves, at 55 miles above Earth during Hurricane Helene, revealing new insights into how severe storms can influence the upper atmosphere and potentially impact satellite operations.
NASA's instruments on the International Space Station detected unknown atmospheric waves in the mesosphere, caused by Hurricane Helene, revealing new insights into how severe weather impacts Earth's upper atmosphere and potentially affecting satellite operations.
NASA's ISS-based Atmospheric Waves Experiment detected gravity waves in the mesosphere caused by Hurricane Helene, revealing how surface weather impacts upper atmospheric conditions and affecting satellite operations and space weather understanding.
NASA's ISS detected unseen atmospheric waves in the mesosphere during Hurricane Helene, revealing a new connection between hurricanes and upper atmospheric dynamics, which has implications for space weather and satellite operations.
NASA's GUARDIAN system successfully detected a tsunami triggered by a magnitude 8.8 earthquake off Russia's Kamchatka Peninsula by analyzing atmospheric pressure waves, providing alerts 30-40 minutes before landfall, and demonstrating a promising tool to enhance early warning systems globally.
Scientists discovered that Japan's Earth-observing Himawari-8 and Himawari-9 satellites have been inadvertently collecting valuable data on Venus for nearly a decade, revealing insights into the planet's atmospheric dynamics, including thermal tides and Rossby waves, and challenging existing calibration methods for Venus spacecraft instruments.
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 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.
