NASA's MAVEN Mars orbiter is officially dead after months of radio silence

Space.com and 5 more

NASA formally ended the MAVEN Mars mission after six months without contact, marking the first formal conclusion of the mission amid an unrecoverable anomaly.
The final turning point came when MAVEN rotated at an unexpected rate, depriving it of solar power and draining batteries until recovery was no longer possible.
A NASA review board will deliver a final assessment in coming months, contributing to the agency’s understanding of what happened to MAVEN.

NASA Finds New Way Earth May Have Received Elements Needed for Life - NASA Science

Science.nasa.gov

NASA finds Earth likely acquired its life-essential elements mainly from the inner solar system, with Jupiter shaping the distribution.
Researchers examined phosphorus-to-nitrogen ratios in iron meteorites and chondrites to trace early solar system material.
Jupiter's growth is linked to limiting the outward flow of phosphorus and nitrogen, influencing inner-solar-system composition.
Inner solar system planetesimals, related to iron meteorites or chondrites, best reproduce Earth’s current phosphorus-nitrogen signature.
The study proposes a two-generation view of planetesimals, linking iron meteorites to the first and chondrites to the second.
The inner solar system contributed the key elements needed for habitable world formation, according to geochemical models.
The research reduces the need for outer solar system chondrite delivery to Earth for life-essential elements.
The findings appear in Science Advances, supported by NASA researchers and institutions.
The article emphasizes how early solar system dynamics shaped Earth’s chemical inventory.
The research provides a context for how life-essential materials became available for early Earth.

Meteor that landed in Cape Cod Bay may have been made of iron and was unusually dense, NASA says - The Boston Globe

Bostonglobe.com

NASA says Cape Cod Bay meteor may be made of iron, with density suggesting iron meteorite composition.
The meteor broke apart at about 31 miles up and produced few small fragments.
Radar data indicated debris descended toward the water, with fragments likely surviving the fiery descent.
NASA estimated the bolide was about 5 feet wide and weighed roughly 5.6 metric tons.
The event released about 230 tons of TNT in energy equivalent.
NASA said there are no plans to attempt a meteorite recovery due to resources and ocean contamination concerns.
A buoy in Cape Cod Bay did not detect unusual wave activity around the event.
The meteor streaked over New England and generated a sonic boom before entering the bay.
NASA notes the density calculation is experimental and subject to further analysis.
The rock traveled about 26 miles through the atmosphere before breaking apart.

Hello, World! NASA Shares New Home for Roman Space Telescope Updates - NASA Science

Science.nasa.gov

NASA’s Roman Space Telescope is slated to launch on Aug. 30, 2026, eight months ahead of schedule.
Final preparations include packing Roman, conducting powered tests, and launch rehearsals at Kennedy Space Center.
The observatory will ride as part of a SpaceX Falcon Heavy rocket to the second Sun-Earth Lagrange point, L2.
Roman will be encapsulated in a protective fairing for liftoff and atmospheric travel.
The mission aims to survey vast sky areas to study dark energy, dark matter, and exoplanets in infrared light.
The Roman Space Telescope will operate at the L2 point for its primary science mission.
The launch prep includes loading about 290 gallons of hydrazine fuel for the mission.
Roman’s launch stage will be a major milestone in NASA’s exoplanet and cosmology research.
The blog provides a behind-the-scenes look at Roman’s road to launch and its journey to L2.

NASA's 'Son of Concorde' to blast Brits to New York quicker than Tenerife flight

Dailystar.co.uk

NASA's X-59 QueSST could cut London–New York flight time to about 3 hours 45 minutes, under four hours.
The X-59 is designed to bypass the sonic boom with a muted sonic thump during flight tests.
Test flights will initially push past 630 mph at an altitude of 43,000 feet.
NASA aims for commercial supersonic travel to return by 2029 if trials succeed.
The 'Son of Concorde' moniker honors the original Concorde, which flew passengers in 1976.
Concorde's history includes a 1996 JFK to London flight time of 2:52:59 before fleet grounding in 2003.
The X-59 aims to deliver a quieter revolution, halting the era of loud sonic booms in commercial travel.
The project advances through wind-tunnel tests and lower-speed flights before high-speed trials.
If successful, the technology could reintroduce commercial supersonic routes within the next decade.

Relativistic electron acceleration at the bow shock of Jupiter and beyond - Nature

Nature.com

Latest finding: Juno observed relativistic electrons upstream of Jupiter's bow shock within a large foreshock transient.
Scale matters: the transient spans several Jupiter radii and dictates the acceleration region size L.
Spectral evidence matches diffusion shock acceleration expectations with a power-law tail.
The study links planetary foreshocks to a universal scaling law for maximum energy.
Hillas-like constraint applied to derive Emax from L and B fields.
Planetary data validate the model at Earth, Saturn, and Jupiter scales.
Astrophysical applicability remains tentative but physically plausible.
SN 1006 and SN 1987A are used to test the model's astrophysical predictions.
The work emphasizes the foreshock transient as an efficient accelerator beyond the shock front.
Future work includes applying the framework to additional astrophysical shocks.

Everything you need to know about NASA’s new 900mph 'Son of Concorde' jet

Dailystar.co.uk

NASA is building the X-59 QueSST, a supersonic jet designed to fly at over 900 mph and cut transatlantic flight times.
The jet could shorten London to New York to about three hours and forty-five minutes.
Test flights will initially push the jet past 630 mph at high altitude before faster trials.
NASA aims for a quieter sonic experience with a muffled sonic boom.
If all goes well, commercial supersonic travel could return by 2029.
The project honors the original Concorde, which ceased operations in 2003.
The X-59 aims to deliver long-distance travel advantages without the harmful noise footprint.
NASA indicates wind-tunnel and preliminary flight tests are already underway.
Britons may be among the first to benefit from future faster transatlantic trips.
The project is named the X-59 QueSST, a nod to quiet sonic technology research.

Satellite science: FSU research increases accuracy of high-resolution ocean surface measurements

News.fsu.edu

FSU researchers publish a framework that improves SWOT satellite ocean measurements by modeling internal tides.
HYCOM-based data assimilation blends physics and observations to correct the ocean state in real time.
The corrected SWOT data showed a 59 percent improvement over current correction methods.
Internal tides cause interference in SWOT measurements, historically viewed as chaotic to fix.
The SWOT satellite, operated by NASA and CNES, observes the ocean surface from about 500 miles up.
The model uses measurements from satellites, floats, moored buoys, and ships to stay aligned with reality.
HYCOM derives the internal tide field directly from ocean physics rather than separate estimation.
Researchers from multiple institutions collaborated, including University of Michigan and CLS Group.
The work was supported by ONR, NASA, and CNES.
The study helps improve understanding of ocean heat and carbon transport and supports climate projections.
