If you asked, most science fiction fans could probably name their favorite spaceships from television or cinema. Whether it’s the USS Enterprise or an Imperial Star Destroyer, they’re all pretty equal on the imaginative scale. However, when it comes to sheer speed, there are some fictional spaceships that are clearly faster than others. The Milano […] The post The Fastest Fictional Spaceships appeared first on Goliath.

Traveling faster than the speed of light, you could go anywhere in minutes -- at least, in the "Star Trek" universe. Is this sci-fi device theoretically possible?

From a distance, a space shuttle looks pretty sturdy. It's enormous and solid, and it can withstand extreme temperatures when it enters the Earth's atmosphere. But in some ways, a space shuttle is delicate.

But can a commercial spacecraft take off on its own from the ground, travel into outer space and land again on a runway? That's the goal of XCOR Aerospace, and it starts with the EZ-Rocket. In this article, we'll learn about the technology behind the EZ-Rocket and see how XCOR plans to expand on this technology in the future.

It's bigger, stronger, more efficient and more precise: The Delta IV Heavy is arguably the greatest rocket built to date. It can put 13 tons of satellite payload into its intended orbit with fuel to spare, and that's just the beginning.

I've heard that Russia's Mir station will be brought down out of orbit and crashed to Earth soon. How will they do that?

In its nearly 30-year history, the space shuttle program has seen exhilarating highs and devastating lows. Learn all about the space shuttle program.

At a drag race, I once saw a rocket car that was supposedly powered by spraying hydrogen peroxide on a silver mesh. The resultant reaction produced huge amounts of pure white smoke and apparently enough thrust to propel the car rapidly down the track. Does hydrogen peroxide really react with silver that way?

In science, we are learning about the atmosphere. It protects us from meteors because it burns them up. So, why doesn't the space shuttle burn up?

Believe it or not, the hardest part of space exploration is getting a spaceship off the ground. Explore the basics of propulsion and learn about both solid-fuel and liquid-fuel rocket engines.
