Editing of the title is subtly inaccurate. Actual title is "We’re building nuclear spaceships again—this time for real" and the article deals with nuclear thermal rockets (NTRs) which are fission reactors that heat a propellant. Thermonuclear refers to fusion. There are designs out there for thermonuclear spaceships, but this article isn't talking about them.
