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.

Psyche Approaches Mars

This composite photo released on July 17, 2026, shows the crescent of Mars grow as NASA’s Psyche spacecraft approached the planet for a gravity assist. Psyche flew by Mars on May 15, 2026, using the planet’s gravity to gain speed and slightly tilt its trajectory. The flyby also gave the team an opportunity to prep for the […]
