Wildfires Force NASA to Evacuate Its Madrid Deep Space Station, Shifting Voyager Tracking to California
Wildfires near Madrid forced NASA to evacuate one of only three Deep Space Network complexes on Friday; all 90 workers got out safely and mission support, including the Voyager 1 downlink, shifted seamlessly to Goldstone in California.

Starship Flight 13 Nails Its First Intact Splashdown — and Drops 20 Real Starlink Satellites
On Flight 13, SpaceX put an intact Starship in the water for the first time and deployed 20 working Starlink V3 satellites — its first real payloads — even as the Super Heavy booster came down hard after an incomplete landing burn.

Hubble Watches a Nova Fire 'Bullets' Through the Milky Way at 20 Million MPH
Hubble imagery reported July 24, 2026 shows a nova launching dense clumps of ejected material across the galaxy at roughly 20 million mph — and astronomers still can't explain where the projectiles come from.

CAPSTONE 02: NASA's Twin Smallsats Will Rehearse the Hardest Trick in Cislunar Space
NASA has announced CAPSTONE 02, a pair of identical ~400 kg spacecraft launching in 2027 into a near-rectilinear halo orbit to practice rendezvous, autonomous navigation and cislunar comms — groundwork for Artemis and a future lunar base.

NASA Reopens Stennis' B-2 Stand to Hot-Fire New Glenn's Hydrogen Upper Stage
NASA and Blue Origin have agreed to prep the historic B-2 test stand at Stennis to hot-fire New Glenn's two-engine, LOX/LH2 second stage this fall — a move that ties the rocket's readiness directly to Artemis.

The Lopsided Galaxy: Hubble Catches NGC 4654 Squeezed on One Side, Stripped on the Other
A new Hubble image of NGC 4654, an intermediate spiral 72 million light-years away in the Virgo Cluster, shows a galaxy being compressed along one flank and unravelled along the other — the combined fingerprint of ram-pressure stripping and a tidal encounter with NGC 4639 some 500 million years ago.

The Last of the Shuttle Engines: Four RS-25s Arrive at Michoud for Artemis III
L3Harris delivered four RS-25 engines with 36 shuttle flights between them to NASA's Michoud facility on July 22, 2026 — the final flight of Space Shuttle Main Engine heritage hardware before Artemis V switches to newly built, 3D-printed engines.

NASA Lost 4,000 Civil Servants Last Year. GAO Says 25 of Its 36 Biggest Projects Are Already Feeling It
GAO's annual NASA project assessment is usually a story about hardware. This year it's a story about people: a 22 percent workforce cut, Goddard down 34 percent, Psyche delayed a year, and a proposed FY2027 budget that would cut another 20 percent.

Lightning Hit a Long March 3B 30 Seconds Off the Pad — and the Rocket Kept Flying
Amateur video caught a lightning bolt hitting a Long March 3B/E about 30 seconds after it left Xichang on July 23. The Tianlian II-06 relay satellite reached orbit anyway — and the footage raises an uncomfortable question about how differently launch ranges treat weather risk.

Mars Runs a Pocket-Sized Version of Earth's Aurora Engine, MAVEN Data Shows
MAVEN data show Mars powers its discrete auroras with a miniature Dungey cycle running on 4-billion-year-old crustal magnetism — 42 of 49 events matched reconnection-friendly conditions. The orbiter died in 2025; the archive is still doing first-order science.

China Rotated a Cold War Orbit Sideways — and Shijian-31 Now Sweeps the Entire GEO Belt
Commercial trackers say China's Shijian-31 has rotated the Soviet-era Molniya orbit onto the equator and detuned its period to 12.5 hours, letting one satellite sweep the entire geostationary belt from 2,000 km above it every 23 days.

Venus Is Not Dead: New 3D Rift Models Say the Planet Is Still Pulling Itself Apart
ETH Zurich's first high-resolution 3D simulations of Venusian rifting, published in Nature Geoscience, use the broad ridges flanking Venus's 10,000-km rift valleys as a geological clock — and conclude some rifts are still spreading at 3-10 cm per year.
