Space is getting dangerously crowded but a new automated system could be the key to preventing catastrophic collisions that threaten our satellites and astronauts. The European Space Agency has developed CREAM (Collision Risk Estimation and Automated Mitigation), a revolutionary technology that aims to transform how we manage traffic in Earth orbit and keep space safe for future generations.

arXiv:2507.21402v1 Announce Type: new Abstract: The interstellar object 3I/ATLAS is expected to arrive at a distance of $53.56(\pm 0.45)$ million ${\rm km}$ ($0.358\pm 0.003$~au) from Jupiter on March 16, 2026. We show that applying a total thrust $\Delta$V of $2.6755{{\rm km~s^{-1}}}$ to lower perijove on September 9, 2025 and then execute a Jupiter Oberth Maneuver, can bring the Juno spacecraft from its orbit around Jupiter to intercept the path of 3I/ATLAS on March 14, 2026. A close fly-by...
