UK Startup Ignites Plasma Inside Nuclear Fusion Rocket

UK startup Pulsar Fusion says it has achieved the first plasma ignition inside a nuclear fusion rocket engine prototype -- a huge step for space travel that could cut missions to Mars "from months-long journeys to just a few weeks," reports Euronews.

Upcoming upgrades include more powerful superconducting magnets designed to better contain and control plasma.
