NASA's Juno Maps Subsurface Heat Across Jupiter's Volcanic Moon Io

NASA's Juno spacecraft used its Microwave Radiometer instrument to map thermal activity beneath the surface of Jupiter's moon Io during two close flybys. The first pass, known as Perijove 57, took place on December 30, 2023, focusing primarily on Io's northern hemisphere. A second flyby, Perijove 58, followed shortly after and extended coverage to additional regions of the moon. Together, the two flybys produced overlapping footprint data that allow scientists to study heat distribution hidden below Io's surface. The findings aim to deepen understanding of the intense volcanic and thermal processes that make Io one of the most geologically active bodies in the solar system.

NASA's Juno Spacecraft Maps Heat Rising Below Jupiter Moon Io's Surface

NASA's Juno spacecraft has captured data revealing heat emanating from beneath the surface of Io, one of Jupiter's moons. The findings come from the Microwave Radiometer (MWR) instrument onboard the probe, which was used to generate a detailed heat map of the moon. Unlike infrared instruments that only measure surface temperature, the MWR's lowest frequency microwave channels — operating at 0.6 and 1.25 gigahertz — can penetrate several meters below Io's surface. This capability allows scientists to study subsurface thermal activity on the volcanic moon in a way that surface-level observations cannot. The data offers new insight into the internal heat processes driving Io's intense geological activity.

NISAR Satellite's L-Band Radar Captures Striking Ice Formation in East Antarctica

The joint U.S.-India NISAR satellite, developed by NASA and ISRO, has produced a detailed radar image of a remote East Antarctic landscape. The image features Nunatak Zaterjavshijsja, a mountaintop protruding through a northeast-flowing ice stream headed toward the ocean. The rocky obstruction creates significant mechanical stress on the surrounding ice, causing extensive fracturing of the surface. NISAR's L-band synthetic aperture radar was the instrument used to capture this data. The resulting image visually resembles a hummingbird, drawing attention to the satellite's capability to reveal fine structural details of polar terrain.

NASA Explores Spacecraft-Based Astrometry to Detect Low-Frequency Gravitational Waves

Researchers at Brookhaven Science Associates are developing a new method to detect gravitational waves at low frequencies using precision astrometry. The approach relies on the fact that gravitational waves passing near Earth cause a tiny but coordinated apparent shift in the positions of all objects across the sky. The proposed innovation involves deploying optically independent spacecraft to measure these minute positional changes with high precision. This astrometric technique offers an alternative observational strategy to existing gravitational wave detection methods. The project aims to open a new window into low-frequency gravitational wave astronomy.

NASA Proposes Optical VLBI Technique to Image Surface Features of Exoplanets

NASA researcher Paul Stankus of Brookhaven Science Associates is working toward capturing visible-light images of Earth-like exoplanets orbiting nearby stars. The project aims to resolve actual surface features — such as continents — on distant worlds, a capability far beyond current technology. The approach involves two key innovations, the first being a new type of nulling interferometer called 'dynamic hierarchical nulling,' which combines multiple telescope inputs to suppress overwhelming starlight. The second stage applies optical Very Long Baseline Interferometry (VLBI) principles to achieve the extreme resolution needed for exoplanet surface mapping. If successful, the technique could mark a landmark advance in humanity's ability to directly study potentially habitable worlds beyond our solar system.

NASA Eyes Light-Levitating Tracers to Sense Atmosphere 30–100 km Up

Rarified Technologies has proposed a novel atmospheric sensing method targeting the largely under-monitored 30–100 km altitude range. The concept involves deploying lightweight tracers that use photophoresis — a process where sunlight exerts force on particles — to remain suspended for potentially months at controlled heights. Unlike natural aerosols, these engineered tracers are designed to produce strong, trackable signals. They would be monitored remotely using satellite-based lidar or radar systems. The proposal was submitted to NASA as part of efforts to improve data collection in a region of the atmosphere that is difficult to study with conventional tools.

NASA Backs Plan to Deploy 10,000 Tiny Steerable Satellites Around Saturn

Northwestern University researcher Michael Rubenstein has proposed a NASA mission to deploy approximately 10,000 actively steerable femtosatellites around Saturn. The miniature spacecraft would conduct in-situ surveys of the planet's ring composition, atmospheric density, and magnetic field distribution. The proposal argues that relying on a single large flagship mission, like the Cassini spacecraft, poses an unacceptably high risk of total mission failure. Spreading the workload across thousands of small satellites would provide redundancy and far broader coverage of Saturn's complex environment.

NASA Concept Aims to Autonomously Sample Planetary Ring Particles In Situ

NASA's Jet Propulsion Laboratory is developing a concept called PRAXIS — Planetary Rings Autonomous EXploration with In-situ Sampling — designed to physically collect particles from planetary rings. No spacecraft has ever directly sampled ring material, making this a potential first in space exploration. The mission targets rings across the solar system, including Saturn's dense rings and the tenuous rings of Uranus and Neptune. Smaller bodies such as Centaurs Chariklo and Chiron, which also possess rings, are among the candidate targets. Scientists believe direct sampling could fundamentally transform understanding of how planetary rings form and are structured.
