Mark Vande Hei outside of ISS (October 10, 2017). This article is from the 2025 Technical Update. The exact date when the crew of Space Shuttle Columbia was lost is readily recalled by Patrick Forrester, as it likely would be for any NASA employee in service that Saturday morning when the Shuttle broke up during [...]

This pair of images shows stars observed Feb. 6, 2026, by the SPARCS space telescope simultaneously in the near-ultraviolet, left, and far-ultraviolet, right. The fact that one star is seen in the far-UV while multiple are seen in near-UV offers insights into the temperatures of these stars, with the one visible in both colors being [...]
Two powerful instruments of the NASA/ESA/CSA James Webb Space Telescope joined forces to create this scenic galaxy view. This spiral galaxy is named NGC 5134, and it’s located 65 million light-years away in the constellation Virgo.ESA/Webb, NASA & CSA, A. Leroy Stars peek through the dusty, winding arms of NGC 5134, a spiral galaxy located [...]

When they pass near one another or collide, gravity pulls their stars into long tails, thin streams, and faint shells – features that preserve the history of these dramatic events. Thanks to deep, high-resolution images from [...]
Download PDF: Efficient Large Displacement/Large Rotation Dynamic Simulations Using Nonlinear Dynamic Substructures Utilizing reduced-order dynamic math models (DMM) in linear system-level dynamic analyses is a well-known practice that enables extreme computational efficiencies. But what about nonlinear system dynamics? Reduced-order DMMs have found their way into contact dynamics. The engineer must look no further than the [...]
