The NASA Engineering and Safety Center (NESC) performed an assessment to characterize the effects of abnormal grain growth (AGG) within a metallic liner of a composite overwrapped pressure vessel (COPV). This effort focused on evaluating the mechanical response of the liner material, including the strain amplification factor (SAF), using a series of custom-designed coupons that [...]

Lights illuminate NASA’s Artemis II SLS (Space Launch System) rocket and Orion spacecraft at Launch Complex 39B at NASA’s Kennedy Space Center in Florida on 01/18/2026. In the coming days, engineers will prepare for the wet dress rehearsal, a two-day test that simulates launch day. The Artemis II test flight will take Commander Reid Wiseman, [...]
Northern Japan, especially the island of Hokkaido, is home to some of the snowiest cities in the world. Sapporo, the island’s largest city and host of an annual snow festival, typically sees more than 140 days of snowfall, with nearly 6 meters (20 feet) accumulating on average each year.Michala Garrison, using MODIS data from NASA [...]

Photo of the Day How is RXJ0528+2838 creating such shock waves? A recently discovered white dwarf star, the farther left of the two largest white spots, RXJ0528+2838, was found 730 light-years away from Earth. Most stars, when done fusing nuclei in their cores for energy, become red giant stars, the cores of which live [...]
A full Moon is seen shining over NASA’s SLS (Space Launch System) and Orion spacecraft, atop the mobile launcher at the agency’s Kennedy Space Center in Florida in the early hours of Feb. 1, 2026.NASA/Sam Lott NASA is targeting Thursday, Feb. 19, as the tanking day for the second wet dress rehearsal ahead of the [...]
Photo of the Day What would it be like to fly free in space? About 100 meters from the cargo bay of a space shuttle, Bruce McCandless II was living the dream -- floating farther out than anyone had ever been before. Guided by a Manned Maneuvering Unit (MMU), astronaut McCandless, pictured, was floating [...]
The sun sets behind NASA’s SLS (Space Launch System) rocket and Orion spacecraft at Launch Pad 39B at NASA’s Kennedy Space Center in Florida.NASA/Sam Lott As part of robustly testing the vehicle prior to flight, NASA engineers are reviewing data after a confidence test Feb. 12, in which operators partially filled the SLS (Space Launch [...]
NASA/Aubrey Gemignani A SpaceX Falcon 9 rocket carrying the company’s Dragon spacecraft is launched on NASA’s SpaceX Crew-12 mission to the International Space Station with NASA astronauts Jessica Meir, Jack Hathaway, ESA (European Space Agency) astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev onboard, Friday, Feb. 13, 2026, from Cape Canaveral Space Force Station in [...]
