NASA TechLeap Prize: Orbital Clarity Challenge

The Orbital Clarity Challenge — the sixth in the NASA TechLeap Prize series — is a collaborative effort between NASA’s Heliophysics Division, Flight Opportunities program, and Center of Excellence for Collaborative Innovation. The Heliophysics Division studies space weather, including how it heats and expands Earth’s outer atmosphere during intense solar activity, creating orbital drag through atmospheric density changes. The […]

NASA Updates Next Steps for Commercial Swift Boost Mission

Due to an ongoing commercial spacecraft attitude control issue, NASA and Katalyst Space announced Wednesday the LINK spacecraft will not capture or boost an agency satellite to a higher altitude to extend its science mission as planned. However, LINK still will attempt to conduct rendezvous and proximity operations with NASA’s Neil Gehrels Swift Observatory to […]

Ancient Milky Way Merger

This artist’s concept, released on Aug. 17, 2026, depicts a collision between our Milky Way galaxy and a dwarf galaxy known as LKH that happened about 12 billion years ago. A study of data from NASA’s Hubble Space Telescope, recently published in the journal Nature Astronomy, shows definitive evidence of a dwarf galaxy merging with the young […]
