Satellite Data Maps Human Impact on Terrestrial Water Storage
Using more than two decades of measurements from the GRACE and GRACE-FO satellites, researchers mapped long-term global water trends with significantly improved spatial detail. Beyond climate variability, the analysis identified 40 regions where changes in terrestrial water storage strongly aligned with human activities such as groundwater irrigation, reservoir impoundment, and land-use changes. In regions like California's Central Valley and northern India, heavy groundwater reliance contributed to accelerated storage declines. The findings may help scientists better monitor how localized trends evolve in response to specific management policies or droughts.
New Modeling Workflow Streamlines Spacecraft Vibration Analysis
Engineers at NASA's Kennedy Space Center have implemented a standardized finite element modeling workflow to improve how they predict and analyze shock and vibration stresses on spacecraft during launch. The updated computer-based method helps teams run what-if comparisons and visualize structural behavior before hardware is built. The Dynamic Environments Group recently used the tool to verify a commercial launch provider's system and address transport shock risks, potentially saving months of manual modeling and helping identify potential failure risks earlier in mission planning.
Simulated Mars Crew Reaches One-Year Milestone in Ground Habitat
The four crew members participating in NASA's Crew Health and Performance Exploration Analog Mission 2 have completed a full year living inside a confined 3D-printed habitat at Johnson Space Center. Throughout the 365-day period, the crew simulated Martian surface operations, managed limited resources, grew crops, and navigated communication delays of up to 45 minutes. The participants are scheduled to exit the habitat on October 31 to begin post-mission evaluations, which will help scientists assess the psychological and physiological impacts of long-duration spaceflight.
As the ESA and JAXA BepiColombo mission approaches its scheduled December 9 arrival at Mercury, mission team members have reflected on the journey through the inner Solar System. Launched on October 20, 2018, the spacecraft has spent eight years traveling across the solar system. Team members described the complex and collaborative international mission in three words to capture the technical challenges of the demanding voyage and the international teamwork that made the upcoming planetary encounter possible.
