1. Why today’s flight matters At 02:31 EDT (08:31 CEST) a brand-new SpaceX Crew Dragon christened Grace roared off pad 39A, carrying four astronauts on Axiom Mission 4 (Ax-4)—and with them the dreams of three nations returning to human space-flight after more than four decades. Among the passengers is Dr Sławosz Uznański-Wiśniewski, who just became…

A burst of high‑speed solar wind from a giant coronal‑hole on the Sun is slamming Earth’s magnetic field this week, prompting NOAA to issue a G2‑level geomagnetic‑storm watch and raising the odds that the aurora borealis will spill far beyond its usual haunts—potentially as far south as Illinois, Ohio and New York on the night of 24–25 June 2025.…

Microwave radiometry is a passive remote sensing technique that measures naturally emitted thermal radiation in the microwave portion (0.3–300 GHz) of the electromagnetic spectrum. In essence, a microwave radiometer detects weak microwave energy from Earth’s surface and atmosphere and expresses it as a brightness temperature, the equivalent blackbody temperature of the emitting source. Unlike optical…

Studying the vast oceans from the deck of a ship or a buoy has always been a daunting challenge. Today, fleets of Earth-observing satellites serve as an “eye in the sky” for oceanographers, providing a continuous, planet-wide view of the seas. Unlike traditional ship-based methods that can only cover limited regions at a time, satellites…

A cascade of newly released commercial‑satellite photographs confirms that last weekend’s U.S. bunker‑buster raid on Iran’s Fordow enrichment plant gouged fresh holes into the mountain and triggered a landslide of rock and debris that experts say may have entombed the centrifuge halls. The imagery—captured by Maxar, Planet Labs and others—has become the centerpiece of a…
