Sugars, “Gum,” Stardust Found in NASA’s Asteroid Bennu Samples

“The asteroid Bennu continues to provide new clues to scientists’ biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft, three new papers published Tuesday by the journals Nature Geosciences and Nature Astronomy present remarkable discoveries: sugars essential for biology, a gum-like substance not seen before in astromaterials, and an unexpectedly high abundance of dust produced by supernova explosions.

Scientists led by Yoshihiro Furukawa of Tohoku University in Japan found sugars essential for biology on Earth in the Bennu samples, detailing their findings in the journal Nature Geoscience. The five-carbon sugar ribose and, for the first time in an extraterrestrial sample, six-carbon glucose were found. Although these sugars are not evidence of life, their detection, along with previous detections of amino acids, nucleobases, and carboxylic acids in Bennu samples, show building blocks of biological molecules were widespread throughout the solar system.”

Greece Turns to Space in Fight Against Wildfires

“With wildfires burning north-west of Athens, Greece is testing whether a new fleet of thermal satellites can give firefighters earlier warning and a clearer view of the blazes that are becoming harder to contain in a warming climate.

The Hellenic Fire System, a constellation of four compact, low-flying thermal satellites, transmitted its first images to Earth in June. The system is due to become fully functional in September, with firefighters still being trained to use it.

But it is already providing data to authorities, including about devastating fires that ripped across popular Greek island resorts and the region of Attica near Athens in recent weeks.”

SpaceX Launches 3 Giant BlueBird Direct-to-Cell Satellites

“A SpaceX Falcon 9 rocket carrying three of AST SpaceMobile's massive direct-to-cell BlueBird satellites launched from Florida's Cape Canaveral Space Force Station at 3:50 a.m. EDT (0650 GMT) on Wednesday, minutes after the opening of its 96-minute window.

Today's launch further expands AST SpaceMobile's constellation in low Earth orbit (LEO), which will beam internet service directly to unmodified smartphones once operational.

The newcomers bring the total number of BlueBird spacecraft launched to 13 and marks a significant milestone toward getting the constellation fully up and running, according to AST SpaceMobile.”

Starlink Ends Quarter With 12 Million Subscribers

“SpaceX reported 12 million subscribers for its Starlink satellite-internet business for the three-month stretch that ended in June. That was double the number of subscribers during the same period in 2025, and represented a slightly higher quarter-to-quarter growth rate versus the start of the year…

Revenue per Starlink subscriber during the latest quarter held steady at $66 from the first three months of 2026, though it was down from $85 per subscriber for the year-earlier period. The company has said it expects this measurement to decline as it signs up customers outside of North America and adds lower-priced service plans.”

NASA Mission Predicts Solar Explosion’s Arrival at Earth

“In the wee hours of 31 May 2025, billions of tons of charged particles erupted from the Sun and began to hurtle in our direction. Spacecraft tracked the liftoff of that huge burst of plasma, enabling U.S. officials to predict when the eruption would strike Earth, within a 12-hour window. But a new view of the Sun’s roiling outer atmosphere could have enabled scientists to peg the solar storm’s arrival time much more precisely—to within just half an hour.

That precision comes from PUNCH, a NASA mission keeping an eye on a part of space that’s been a blind spot for space weather. Like a sensitive 3D camera whose field of view covers half the sky, it watches everything escaping the Sun’s atmosphere and traveling toward us. 'We can track space weather all the way across the inner Solar System,' says Craig DeForest, the mission’s principal investigator.

He and his colleagues have now shown that based on those observations, they could have forecast within minutes when the 2025 storm would have struck Earth’s magnetic field, threatening satellites, power grids, and other technologies.”
