Don't Get Too Excited About NASA's New Miracle Engine

News spread quickly this week that a propulsion system said to violate the laws of physics had been validated by no less an authority than NASA itself. Could a fuel-less space drive propelled by microwave thrust –something once deemed impossible – actually be possible? We spoke with some experts. Let's just say… » 8/04/14 11:30am 8/04/14 11:30am

Boeing Fuselages Make A Splash In Montana River

A trio of Boeing fuselages wound up in the Clark Fork River this week, when a train carrying the aircraft derailed near Superior, Montana. Thankfully, no one was injured – but we can't help but wonder what Boeing intends to do with these castoff parts. See more photos of the aftermath by Kyle Massick at King 5 News. » 7/05/14 1:00pm 7/05/14 1:00pm

Rocket science, explained with soda bottles

Fuel and oxidizer. Together they make propellant, which can be used to launch a rocket – but for the best results, you need to find the right ratio. Too much of one or the other, and your exhaust velocity begins to drop. Less exhaust velocity means less thrust — and less thrust means you will not go to space today. » 4/11/13 4:20pm 4/11/13 4:20pm

How Will Humans Get to Alpha Centauri?

Astronomers have discovered an Earth-sized exoplanet orbiting a star in Alpha Centauri, just 4.3 light-years from Earth. With surface temperatures in excess of 2,000 degrees fahrenheit, this particular planet would be inhospitable, but the fact that it exists at all raises hopes of finding another, more human-friendly… » 10/18/12 8:15am 10/18/12 8:15am
