FUSION & ADVANCED NUCLEAR POWER

NASA's Jupiter Icy Moons Orbiter (JIMO) project, initiated in 2002 with a budget of $463 million, was aimed at exploring Jupiter's icy moons but was canceled in 2005 without any hardware built. The project faced technical challenges and lacked clear scientific support, ultimately leading to its failure amid shifting NASA priorities and budget constraints. The legacy of JIMO, while largely forgotten, influenced subsequent missions like the Europa Clipper, which is set to launch in 2024.
