- Mars North Pole Ice Far Cleaner Than Models Predicted — Universe Today
A pair of researchers used data from the OMEGA spectrometer, CRISM, and the Surface Stereo Imager on the Mars Phoenix Lander to recalculate dust content in the north polar cap. They arrived at a new estimate of three percent dust by mass for the top ice layer. The revision stems from recognizing a multilayered structure of ice over thin dust layers over more ice. Previous models had assumed twenty five percent dust by mass. The team observed seasonal frost that is dustier in winter and cleaner ice exposed in summer.

A study in Mayo Clinic Proceedings examined U.S. astronauts and found elevated hip fracture rates after flights exceeding ninety days. Researchers applied Bayesian probabilistic modeling to fracture reports from annual exams to overcome small sample sizes. Lead investigator Jean D. Sibonga at NASA Johnson Space Center noted that astronauts may resume demanding activities after feeling recovered despite underlying bone changes. Co-author Matthew T. Drake highlighted the limitation of small astronaut cohorts in prior data. The findings support expanded long-term skeletal health assessments ahead of extended Artemis and commercial missions.

SpaceX plans a Crew-13 astronaut mission on a Falcon 9 from Cape Canaveral at eleven ten a.m. EDT. The Transporter-18 rideshare carrying one hundred thirty payloads follows from Vandenberg at two eighteen p.m. EDT. A Falcon Heavy will then launch the classified NROL-97 mission from Kennedy Space Center at eleven fifty three p.m. EDT. This marks only the second time the company has flown three missions inside a thirteen-hour window. The schedule comes the day after Starship Flight 14 reached orbit for the first time.

An international team used the Atacama Large Millimeter/submillimeter Array to image WISPIT 2b at fifty seven astronomical units from its star. The protoplanet is roughly five Jupiter masses and sits four hundred thirty light-years away. A companion, WISPIT 2c, orbits at fifteen astronomical units with an estimated mass of eight to twelve Jupiter masses. Lead author Myriam Benisty reported seeing both planets carve gaps and cavities while gas swirls predicted by simulations appear around WISPIT 2b. The image provides the first direct view of disk-planet interactions previously only modeled. Source: universetoday.com - Coldest Known Lava World May Retain an Atmosphere — Universe Today
Researchers observed HD 3167 b with the James Webb Space Telescope during its secondary eclipse. The Earth-sized planet orbits its K-type star every zero point nine six Earth days at one hundred fifty four light-years distance. Its measured dayside temperature proved cooler than expected, suggesting heat redistribution to the night side. The finding challenges the prior view that only hotter lava worlds can sustain atmospheres. The study appears in The Astrophysical Journal Letters.

Prime Minister Rumen Radev spoke at the Euronews Defense and Space Summit in Brussels. He noted Bulgaria was the sixth country to send a citizen to orbit and pointed to EnduroSat as a current example of national capability. Radev stated that two decades ago space access required enormous financial and industrial resources. Advances in technology and artificial intelligence have now broadened opportunities for additional countries.

The company is building satellites that convert raw signals into answers while still in orbit. The design targets defense and commercial users who need rapid insight into events and locations. Existing ground-based systems introduce delays that the new architecture aims to eliminate. Source: spacenews.com - Sunrise-III Balloon Observatory Maps Quiet-Sun Magnetic Structures — Phys.org Space
A National Astronomical Observatory of Japan team flew the Sunrise-III instrument in the stratosphere during twenty twenty four. Observations revealed unexpectedly intricate magnetic structures above quiet regions of the Sun. The work is published in The Astrophysical Journal Letters.

A study in Science Bulletin presents evidence that some minute-long X-ray flashes originate from merging neutron stars. Researchers had previously associated only short gamma-ray bursts with these collisions. The new connection suggests certain longer flashes may hide among events whose origins remained unclear.

Cosmic Spotlight
The protoplanet imaging result stands out because it moves beyond computer models to show actual gas swirls around a forming world. WISPIT 2b and its companion are actively sculpting the disk at distances of fifteen and fifty seven astronomical units. The Atacama Large Millimeter/submillimeter Array captured structures that simulations had long predicted but never directly recorded. This single observation supplies a new benchmark for how planets interact with their birth environment. It also raises the practical question of how common such visible interactions are among other young systems still embedded in gas. What fraction of protoplanetary disks will reveal similar features once observed at comparable resolution?
Cosmic Deep Dive: How Magnetic Fields Shape Quiet Regions of the Sun
A single strand of solar magnetic field can stretch across distances that would span the entire continental United States if laid end to end on Earth. The Sunrise-III balloon flight lifted an instrument suite above most of the atmosphere for several hours and recorded magnetic structures above areas previously considered magnetically simple. Those structures twist and reconnect on scales smaller than a typical sunspot yet still channel energy upward into the corona. The data showed field lines that fold back on themselves in patterns no current model fully reproduces. One open question is why the quiet Sun maintains such complexity when the underlying convection should smooth it out.
