Teams with NASA’s Exploration Ground Systems Program begin integrating the interim cryogenic propulsion stage to the SLS (Space Launch System) launch vehicle stage adapter on Wednesday, April 30, 2025. The four-story propulsion system, built by Boeing and ULA (United Launch Alliance), is powered by an RL10 engine that will enable the Orion spacecraft to build up enough [...]
NASA and the Korea AeroSpace Administration (KASA) signed an agreement May 2 for KASA to fly a CubeSat on NASA’s Artemis II test flight next year. K-Rad Cube will use a dosimeter made of material designed to mimic human tissue to measure space radiation and assess biological effects at various altitudes across the Van [...]

X-ray: NASA/CXC/Northwestern Univ./F. Yusef-Zadeh et al; Radio: NRF/SARAO/MeerKat; Image Processing: NASA/CXC/SAO/N. Wolk Astronomers have discovered a likely explanation for a fracture in a huge cosmic “bone” in the Milky Way galaxy, using NASA’s Chandra X-ray Observatory and radio telescopes. The bone appears to have been struck by a fast-moving, rapidly spinning neutron star, or pulsar. Neutron stars are the densest known [...]
