NISAR Satellite Data Now Public, Captures Antarctic Ice Movement

·1 views

NASA and ISRO have made data from the NISAR satellite publicly available starting July 20. The joint US-India Earth observation satellite carries two radar instruments — an L-band and an S-band radar — whose processed data files are being released on an ongoing basis. The data is intended to help researchers and other users monitor changes across Earth's surface, including ice movement. Among the early findings, the satellite's imagery has revealed a hummingbird-shaped pattern in Antarctica, highlighting the instrument's high resolution and capability.

NASA Selects 2026 NIAC Phase I Projects Including Venus Rover and Sun-Dimming Concepts

NASA has announced its 2026 selections for the NASA Innovative Advanced Concepts (NIAC) Phase I program, funding early-stage research into bold space technologies. One project, led by Saptarshi Bandyopadhyay at JPL, proposes using a controllable dust cloud to reduce solar insolation in a concept called DimSun. Another JPL proposal by David Bugby, named CANVAS, aims to develop a mobile, survivable architecture capable of operating on the surface of Venus. A third selection from the University of Central Florida, led by Anish Damodaran, seeks to advance submillimeter space interferometry using photonic technologies. The NIAC program supports visionary research that could eventually shape future NASA missions.

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.
