Sub-Neptunes May Be 'Soot Factories' Running on Natural Diesel Engines, JWST Data Suggests
A UChicago team led by a former combustion chemist argues sub-Neptune atmospheres breed PAHs — the soot of diesel exhaust — peaking near 600 K and matching JWST and Hubble's puzzling haze trend.

What Artemis II Taught NASA: Real Orion Flight Data Now Shapes the Moon-to-Mars Blueprint
Real Orion flight data from Artemis II is now directly shaping NASA's Moon-to-Mars architecture, as engineers apply lessons from Johnson Space Center's Ion venue to systems that will define how humans reach the Moon — and eventually Mars.

TESS Discovers the Puffiest Planets on Record—and They Challenge Everything We Know About Gas Giants
NASA's TESS mission has catalogued TOI-791 b and c, two gas giants orbiting a Sun-like star 1,113 light-years away so inflated relative to their mass that one has the density of cotton candy—shattering records and straining planet-formation theory.

Phones, Meet Space: AST SpaceMobile Lofts Its First Block 2 BlueBirds
A pre-dawn Falcon 9 carried BlueBirds 8, 9 and 10 — AST SpaceMobile's first operational Block 2 satellites, built to beam broadband straight to ordinary 4G and 5G phones — marking the company's pivot from testing toward live direct-to-cell service.

Why Giant Planets Spin Faster Than 'Failed Stars': Keck's Largest Spin Survey Draws the Line
Keck's KPIC instrument measured the rotation of 32 directly imaged worlds and found giant planets spin up to three times faster than heavier brown dwarfs — turning spin into a tool that tells real planets from 'failed stars.'

Space Force Bets on a Jam-Resistant Swarm: First Two PTS-G Satellites Ordered for $437.7M
The U.S. Space Force awarded Viasat and Intelsat General contracts totaling $437.7 million to build the first two operational PTS-G 'Swarm 1' satellites — small, maneuverable, dual-band anti-jam spacecraft meant to replace the aging AEHF fleet, with launch slated for 2028.

How Venus Got Its Backward Day: A Moon-Sized Impactor May Have Flipped the Planet
New impact simulations presented at EGU 2026 argue a single moon-sized, high-velocity impactor striking young Venus at a steep angle could explain the planet's bizarre 248-day retrograde spin — and why it has no moon.

Boeing and NASA Stay Committed to Starliner-1 While a Launch Date Remains Nowhere in Sight
NASA and Boeing reaffirmed their commitment to the Starliner-1 crewed ISS mission, but with no firm launch date set and infrastructure constraints mounting, the program's path forward remains deliberately vague.
