NASA’s Juno Takes Temperature of Jupiter’s Fiery Moon Io
Lee esta historia en español aquí. NASA’s Juno mission has provided the first measurements of the temperature below the surface of Jupiter’s moon Io, revealing significant heating within the shallow subsurface of the most volcanically active world in the solar system. Collected during two close flybys, the data also shows that most of Io’s surface is remarkably smooth and composed of…

NASA Joins Genesis Mission to Accelerate AI-Driven Discovery
NASA is supporting the Genesis Mission, a national effort to drive the use of artificial intelligence in tackling complex scientific and engineering challenges to advance a new era of discovery. President Donald J. Trump issued the Executive Order “Launching the Genesis Mission” on Nov. 24, 2025, creating a national mission to leverage artificial intelligence to accelerate scientific discovery. The mission…

A Week of Smoky Skies Across North America
Play Video Wildland fire activity in Canada ramped up in July 2026, a time of year when lightning ignitions typically increase, according to a seasonal outlook published by several North American fire agencies. The blazes sent smoke plumes pouring across the U.S. and Canada, affecting air quality in both countries. This animation tracks brown carbon, the organic aerosols emitted by fires…

NISAR’s L-Band Radar Reveals ‘Hummingbird’ in Antarctica
Description Data from the Earth-orbiting U.S.-India NISAR (NASA-ISRO Synthetic Aperture Radar) satellite’s L-band radar was used to produce an image of Nunatak Zaterjavshijsja — a mountaintop in East Antarctica — poking out amid a stream of ice flowing northeast to the ocean. The obstruction causes stresses in the ice, heavily fracturing the surrounding surfaces with deep cracks, called crevasses, which…

Photophoretic Tracers for Near-Space Remote Sensing at 30-100 km Altitudes
Benjamin SchaferRarified Technologies, Inc. We propose a new approach to atmospheric sensing at 30-100 km altitudes using photophoretically levitating tracers. These lightweight structures harness sunlight to remain suspended for up to months at controlled altitudes and can be remotely tracked by satellite-based lidar or radar. Unlike natural aerosols, these tracers are designed to provide strong and tunable backscatter at standard remote sensing…

Precision Astrometry Using Optically Independent Spacecraft for Graviational Wave Detection
Paul StankusBrookhaven Science Associates The scientific goal is to enable a new method for observing gravitational waves at low frequencies, based on the astrometric GW signature — gravitational waves passing by the Earth will cause a (very small) coordinated apparent motion of all sky objects. Our innovation is to deploy a new approach to precision astrometry using quantum mechanical two-photon interference,…

Robotically Assembled Electromagnetic Metamaterials for Long-Range Space Situational Awareness
David SmithDuke University The increasing population of spacefaring vehicles and satellites motivates increasingly powerful technologies for space situational awareness (SSA). While the US space surveillance network (SSN) is able to monitor objects down to about four inches in size using, for example, the latest upgrade to the space fence, the associated requirements limit implementation to ground-based tracking of low earth orbit…
