In the outer reaches of our solar system, far beyond the orbit of Pluto, lies Sedna, one of the most mysterious objects ever ...

In the frozen outskirts of the solar system, a reddish dwarf planet orbits in silence. Known as Sedna, it is so distant that ...

Solar thermal propulsion looked like the best option. “It’s taken me back to my SpaceX Raptor days, where we can move fast and break things, and iterate more quickly,” he said.

Sedna will make its closest approach to the Sun in 2076, giving us a rare opportunity to visit the planetoid before it drifts ...

The NSWR is also fission-based and promising but less mature. Fusion-based propulsion (e.g., Daedalus) offers superior potential but awaits technological breakthroughs. Beamed power to ion drives or ...

Furthermore, prototypes of solar thermal propulsion tech, made with special materials capable of withstanding high temperatures (2,800 degrees Kelvin/2,500 Celsius), have already been built and ...

Debrief: Can Solar Thermal Propulsion Eclipse Nuclear In Spacecraft? is available to both Aviation Week & Space Technology and AWIN subscribers. Subscribe now to read this content, ...

Nuclear thermal propulsion is a technology that can double the propellant efficiency of chemical rockets, cutting travel time by half. In a nuclear thermal rocket engine, a fission reactor ...
