NASA has selected eight new companies and will acquire new data products from six existing Commercial Satellite Data Acquisition contract holders to expand the range of commercial satellite data available to researchers, civil agencies, and decision-makers. Such measurements supplement NASA’s Earth satellites by contributing high-resolution and frequent observations to enhance the agency’s set of data. […]

Description A prototype four-wheel rover developed at NASA’s Jet Propulsion Laboratory with advanced mobility and robotic autonomy capabilities trundled across the Colorado Desert near Plaster City, California, during a field test in March 2026. Called ERNEST (Exploration Rover for Navigating Extreme Sloped Terrain), the rover served here as a testbed for autonomy software developed for […]

On a bleak stretch of the Colorado Desert in Southern California, a compact four-wheeled rover recently trundled about 16 miles (26 kilometers) with minimal intervention from the team of engineers trailing it. Called ERNEST (Exploration Rover for Navigating Extreme Sloped Terrain), this prototype is being used by NASA to advance both robotic autonomy and the […]

This NASA Hubble Space Telescope image features a galaxy cluster, called CL0016+1609 or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensively studied clusters at X-ray and radio wavelengths. The X-ray observations of this cluster revealed that it is two clusters merging along our line of sight. Researchers […]

NASA Wednesday announced a new public‑private partnership to advance Mars science by combining the agency’s scientific leadership with commercial innovation. Under this model, NASA will provide the Aeolus atmospheric‑science instrument payload suite, while Relativity Space supplies the spacecraft, rocket, and cruise operations necessary to deliver the instruments to Mars. This partnership reflects NASA’s growing commitment […]

Some stars have planets. Others are orbited by brown dwarfs, balls of gas too massive to be planets, but too low-mass to be stars. Astronomers love these brown dwarf-star pairs because being paired with a star helps reveal a brown dwarf’s age. Ages of astronomical objects are often hard to measure, but essential for understanding […]
