This NASA/ESA Hubble Space Telescope images showcases the galaxy NGC 2217.ESA/Hubble & NASA, J. Dalcanton; Acknowledgement: Judy Schmidt (Geckzilla) The magnificent central bar of NGC 2217 (also known as AM 0619-271) shines bright in the constellation of Canis Major (The Greater Dog), in this image taken by the NASA/ESA Hubble Space Telescope. Roughly 65 million light-years from Earth, this barred [...]

Identification of Noise Sources During Launch Using Phased Array Microphone Systems  Every part of a launch vehicle, launch pad, and ground operation equipment is subjected to the high acoustic load generated during lift-off [1]. Therefore, many extreme measures are taken to try to suppress this acoustic environment by damping with a water deluge system [...]

A strategy for transferring spacecraft trajectories between flight mechanics tools, called Trajectory Reverse Engineering (TRE), has been developed[1]. This innovative technique has been designed to be generic, enabling its application between any pair of tools, and to be resilient to the differences found in the dynamical and numerical models unique to each tool. The [...]

NASA partners with commercial companies to provide safe, reliable, and cost-effective transportation of cargo and crew members to and from the International Space Station. A platform for long-duration research in microgravity, the station has operated continuously for more than 23 years, its crew members conducting a broad range of technology demonstrations and thousands of experiments [...]

It took the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission just 13 minutes to reach low-Earth orbit from Cape Canaveral Space Force Station in February 2024. It took a network of scientists at NASA and research institutions around the world more than 20 years to carefully craft and test the novel instruments that allow PACE [...]
