Advancements in military technology see new developments with the Air Force’s drone wingman program lifting off, hinting at future air combat strategies.
📰Detailed Coverage
Restarting Nuclear Power in Space
A recently hosted event revisited the longstanding but re-emerging topic of nuclear power in space, a concept dormant since a single reactor flight in 1965. The discussion focused on the potential of nuclear reactors to fuel spacecraft missions beyond the limitations of current solar and chemical systems, promising new frontiers in prolonged space exploration.
As technology progresses, the integration of such power sources could revolutionize deep space missions, enhancing capabilities for prolonged operations where sunlight is inaccessible, and significant propulsion changes are required.
