A nuclear fusion rocket could be the key to unlocking speedy flights in space exploration, and one company hopes to test it as early as 2027.

Even then, a hypersonic engine needs to operate at temperatures in the neighborhood of over 2,000 °C (3,632 °F). Even titanium alloys melt in that kind of heat.

Unlike conventional chemical rockets, Sunbird relies on nuclear fusion – a process that replicates the energy production at the core of stars – to propel spacecraft.
