Northrop Grumman’s Cygnus XL cargo craft is pictured in the grips of the Canadarm2 robotic arm following its capture on Sept. 18, 2025. Cygnus XL is Northrop Grumman’s expanded version of its previous Cygnus cargo craft increasing its payload capacity and pressurized cargo volume.NASA Live coverage of the departure of Northrop Grumman’s Cygnus XL cargo [...]
Photo of the Day Is this a cosmic monster ready to devour an unsuspecting galaxy? Thankfully, that is not the case. The red “monster” shown in the featured image is Cometary Globule CG 4, 1,300 light-years away in the Constellation Puppis. CG 4 is a molecular cloud, where hydrogen becomes cold enough to form [...]

Photo of the Day Are lasers from giant telescopes being used to defend the Earth? No. Lasers shot from telescopes are now commonly used to help increase the accuracy of astronomical observations. In some directions, Earth atmosphere-induced fluctuations in starlight can indicate how the air mass over a telescope is changing, but in other [...]
Download PDF: Insights into Spallation Mechanisms of Thermal Protection System Materials from Mass Spectrometry and HyMETS Testing An effort was undertaken to investigate the mechanisms responsible for internal pressure build up within thermal protection system (TPS) materials subjected to high-enthalpy environments. Understanding how gases evolve, migrate, and interact with the microstructure of a TPS is essential for [...]
