Scientists may have just figured out how to create a radiation shield for deep space.

Private companies launching humans into space is a profound game changer. We just need to follow it to its logical conclusion.

If you want to explore our solar system, you need to prepare for multi-year journeys. But a new discovery in nanoscale engineering could help cut the travel time between worlds.

NASA appears to be sick and tired of having to wait until the mid-2020s to return to the Moon on a future rocket that will be inferior to the private ones already flying, and easily lapped by ones currently being built.

Buckle up steampunk enthusiasts, it turns out that not only are steam-powered space probes possible, they might be perfect for hopping between comets and asteroids on research and mining missions.

If we're going to have astronauts working and living in space for years at a time, cramming them in tight, fixed spaces without artificial gravity is doing them, and us, a major disservice.

Single stage to orbit spacecraft have been mothballed for decades. But with the potential of space tourism, there may be an incentive to take another run at designing them.
