The First Air-Breathing Satellite Gets a Bus: Kreios Space Taps NanoAvionics to Fly an Engine That Eats the Atmosphere
Spanish startup Kreios Space will fly the first orbital demo of air-breathing electric propulsion on a Kongsberg NanoAvionics MP42 bus in 2028 — a ~200 kg satellite that scoops atmospheric oxygen and nitrogen for propellant, aiming to make 150-300 km orbits sustainable without carrying fuel.

Lucy Turns Its Sharpest Camera on Four Trojan Targets in a Dress Rehearsal for the 2027 Flybys
NASA's Lucy spent spring 2026 photographing Eurybates, Polymele, Leucus and Orus from hundreds of millions of miles away — calibration shots under flyby-like lighting that Earth's telescopes can't reproduce, ahead of close passes at 300-600 miles starting August 2027.

Typhoon-Delayed Michibiki-7 Set to Complete Japan's GPS Backup Constellation — and It's Carrying a U.S. Space-Surveillance Payload
After Typhoon Dolphin scrubbed one date and weather killed another, JAXA's H3 Flight 9 is now set to loft QZS-7 from Tanegashima on August 11 — completing Japan's seven-satellite GPS-augmentation system while hosting a second MIT Lincoln Laboratory surveillance payload for the U.S. Space Force.

Rubin Observatory Finds Its First Ultra-Faint Milky Way Satellite: Meet Aquarius IV
Rubin Observatory's early-preview data has already turned up Aquarius IV, a 13-billion-year-old dwarf galaxy so faint it barely outshines a single bright star — an early hint of the dozens more the LSST survey is expected to uncover.

Sharpest-Ever Sun Images Reveal Swirling Instabilities Hiding in Plain Sight
The Inouye Solar Telescope's highest-resolution images yet show Kelvin-Helmholtz vortices are everywhere on the Sun's surface, not rare events — a discovery that may help crack the decades-old mystery of why the corona is millions of degrees hotter than the surface below it.

SkyFall's Ice-Hunting Radar Antenna Survives 200 Simulated Mars Landings
JPL put a featherweight fabric radar antenna for NASA's nuclear-delivered SkyFall Mars helicopters through 200 simulated landings without measurable performance loss, clearing a key hurdle ahead of a late-2028 launch.

August 12 Total Solar Eclipse Will Cross Greenland, Iceland and Spain — Then Hand Off to the Perseids
A total solar eclipse sweeps from the Denmark Strait through Iceland into northern Spain on August 12, 2026, then gives way to a moonless, "optimum" Perseid peak the same night.

A Dead Star's X-rays May Have Just Confirmed a 90-Year-Old Prediction About Empty Space
NASA's IXPE spacecraft, paired with NICER and Australia's Murriyang radio telescope, caught magnetar 1E 1547.0-5408 emitting X-rays polarized up to ~80% — evidence that its trillion-times-Earth magnetic field bends empty space itself, as QED predicted in 1936.
