Rocket Report: SpaceX salvages Starship wreckage; pessimism for Virgin Galactic
The penultimate flight of Japan's workhorse H-IIA rocket deploys a spy satellite. Enlarge / A salvage ship raises a portion of SpaceX's Super Heavy booster from the Gulf of Mexico. This booster was used on the most recent Starshi.....»»
Advanced data shed light on gravitational basins of attraction that shape the movement of galaxies
A new study has mapped out the gravitational basins of attraction in the local universe, offering fresh insights into the large-scale cosmic structures that shape the movement of galaxies. The study has been published in Nature Astronomy......»»
Hubble finds that a black hole beam promotes stellar eruptions
In a surprise finding, astronomers using the NASA/ESA Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its trajectory. The stars, called.....»»
NASA"s Artemis science instrument gets tested in moon-like sandbox
On Sept. 9 and 10, scientists and engineers tested NASA's LEMS (Lunar Environment Monitoring Station) instrument suite in a "sandbox" of simulated moon regolith at the Florida Space Institute's Exolith Lab at the University of Central Florida in Orla.....»»
Satellite data fusion enhances the early detection of convective clouds
As global warming continues, convective weather events are becoming more frequent. The early stage of these storms, known as convective initiation (CI), can be monitored using geostationary satellites. However, detecting CI accurately remains a chall.....»»
Completed experiments on International Space Station to help answer how boiling and condensation work in space
After a decade of preparation and two years of active experiments in space, a facility that Purdue University and NASA's Glenn Research Center in Cleveland designed, built and tested has completed its test campaign on the International Space Station......»»
Balloon mission tests quantum sensor technology
A WashU team launched the Dilution Refrigerator Transition Edge Sensor (DR-TES) mission on Sept. 24 from NASA's scientific balloon facility in Fort Sumner, N.M. The mission is testing a sophisticated cooling system and a novel gamma-ray detector arra.....»»
NOAA shares first data from GOES-19 EXIS instrument
The Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) onboard NOAA's GOES-19 satellite, which launched on June 25, 2024, are powered on, performing well, and observing the sun......»»
NASA analysis shows irreversible sea level rise for Pacific islands
In the next 30 years, Pacific Island nations such as Tuvalu, Kiribati, and Fiji will experience at least 8 inches (15 centimeters) of sea level rise, according to an analysis by NASA's sea level change science team. This amount of rise will occur reg.....»»
Record-breaking laser demonstration completes mission
NASA's TBIRD (TeraByte InfraRed Delivery) demonstration and its host spacecraft—the PTD-3 (Pathfinder Technology Demonstrator-3)—have completed their technology demonstration. The TBIRD payload spent the past two years breaking world records for.....»»
Researchers explore novel approach to map forest dieback in satellite images
Forests and woodlands cover one third of Earth's surface and play a critical role in carbon sequestration, water regulation, timber production, soil protection, and biodiversity conservation. Accelerated by climate change, the decline of these and ot.....»»
Robotic moving "crew" preps for work on moon
As NASA moves forward with efforts to establish a long-term presence on the moon as part of the Artemis campaign, safely moving cargo from landers to the lunar surface is a crucial capability......»»
Rising waters, waning forests: Scientists are using tree rings to study how rising sea levels affect coastal forests
Sunlight filters through the canopy of pines, holly, sweet gum, and red maple while bird calls echo in the distance. These coastal forests may seem like others in the Mid-Atlantic, but a hidden challenge looms. Standing tall next to their salt marsh.....»»
