GRB 250702B: Seven‑hour repeating gamma‑ray burst points to star torn apart by intermediate‑mass black hole

On 2 July 2025 NASA's Fermi telescope recorded GRB 250702B, a repeating gamma‑ray burst that persisted for over seven hours and produced multiple distinct flares across a day — nearly double previous records. A new MNRAS paper argues the source is a star tidally disrupted by an intermediate‑mass black hole.

DART Alters Didymos System’s Solar Orbit, Validates Kinetic-Impactor Planetary Defense NASA's DART mission deliberately altered the Didymos binary system's orbit around the Sun, demonstrating that a kinetic impactor can measurably change an asteroid's trajectory and serve as an effective planetary-defense tool for deflecting near-Earth objects. The result validates kinetic-impact techniques used in deflection planning.

Payload shortfalls and commercial competition cloud future of NASA’s SLS NASA has told employees it is struggling to find payloads that justify use of the Space Launch System, as program costs climb and commercial heavy‑lift alternatives mature. That manifest shortfall intensifies pressure on SLS's budget, schedule and its future role in Artemis and science missions.
