Fusion-Drive Spacecraft: Express Solar System Travel, If We Figure It Out

The concept thruster would make the trip to Titan over twice as fast as Cassini did.


A team of scientists is furiously working away at a spacecraft thruster that they say could reach Saturn’s moon Titan in less than half the time it took the satellite Cassini.

There’s just one catch: They’re talking about a fusion drive, Universe Today reports — and thus far scientists are totally unable to harness the power of nuclear fusion in any sort of practical way. But if it somehow comes to fruition, the fusion drive could radically enhance the way we explore the cosmos.

Traveling Light

The research, which, holding true to its theoretical nature currently exists in an unpublished preprint form, was conducted by aerospace engineers at New York City College of Technology and Italy’s Politecnico di Torino, using data from an experimental drive at the Princeton Plasma Physics Laboratory. The team found that a fusion drive-powered spacecraft could present the best of both worlds: It would have the energy efficiency of an electric engine with the powerful thrust of a fuel-powered one.

And because the fusion drive would also be able to power the spacecraft throughout its mission, it wouldn’t need to carry separate generators.


Long Shot

Of course, this is all speculative, but Universe Today argues that the scientists working on fusion thrusters have time: Earth and Titan won’t line up in the ideal position for a launch until the year 2046.

That gives scientists time to develop the perpetually “30-years-away” technology, but there’s also a whole lot of chance involved in the assumption it works out.
