ETH Zurich isotope measurements on half a gram of NASA's OSIRIS-REx sample overturn the idea that Bennu formed late and far out, and suggest it holds the original recipe for rocky planets.
The August 31 burn was more than 99 percent accurate. Goddard's center director credited 'exquisite planning by our orbital dynamics team, brilliant execution by the operations team, and a precise launch from SpaceX.' A second burn later this month is expected to add four more years.
An Intuitive Machines image specialist spotted the fresh scar on Oct. 24, 2025, and 'dropped everything.' The blast churned the surface over 66 miles and left a 4-mile cold spot. The IAU has named it McGetchin.
The IC 348 panorama shows newborn stars firing jets into the surrounding gas, two protostars with nearly parallel outflows, and a planet-mass object that appears to have its own disk. The lightest brown dwarfs also carry an unidentified hydrocarbon in their atmospheres.
Working from OSIRIS-REx samples, researchers measured the asteroid's surface strength at under one pascal and built a framework linking that strength to the size and shape of individual grains.
A $30 million rescue spacecraft went into an uncontrollable spin weeks after launch and never recovered its pointing. After 22 years of catching gamma-ray bursts, Swift is falling about five miles a month.

The planet's north pole has worn a hexagon for four decades. The new southern decagon is still strengthening — and two amateur astronomers saw the first hints of it.
WatchThe executive order, signed at Johnson Space Center, would build a fourth service academy for the Space Force, NASA and the commercial launch industry. Ted Cruz is already lobbying to put it in Texas.
A WB-57 jet at 50,000 feet will run down the Moon's shadow with four cameras shooting 20 frames a second, while roughly 86 balloons go up over Iceland and Spain.
NASA's IXPE telescope stared at the magnetar 1E 1547.0-5408 and found X-ray polarization nearly three times higher than any comparable source. The leading explanation is vacuum birefringence: the vacuum itself behaving like a lens.
WatchThe discarded Falcon 9 upper stage that launched two private lunar landers in January 2025 drifted for eighteen months and hit near Einstein Crater at 6:35 UTC Wednesday. Nobody photographed the collision, but the Very Large Telescope read its chemical signature.
Ice-rich lunar soil carries seismic waves two to three times faster than dry soil, a University of Maryland-led team reports. China's Chang'e-7 lands a seismometer near Shackleton Crater later this year, and it can test the idea.
The polygonal fractures in Valle Grande measure two to three inches across and climb a 20-foot butte. Scientists have three competing explanations and no answer yet.
The spacecraft skimmed 2,864 miles above Mars on May 15 to steal speed for its trip to a metal asteroid. The flyby doubled as a full dress rehearsal — and produced a timelapse of the Red Planet.
Individual readings from the rover's Mössbauer spectrometer were too noisy to show it. Combined into one composite spectrum, they revealed crystalline hematite sitting in ordinary Martian soil.
Artemis III has been rewritten as a dress rehearsal: three rockets launching in quick succession in 2027, two prototype landers, and a crew that stays in Earth orbit the whole time.
