How the EZ-Rocket Works

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.

    Can you make a rocket engine using hydrogen peroxide and silver?

    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? See more »

  • Meteors burn up when they hit the Earth's atmosphere. Why doesn't the space shuttle?

    Meteors burn up when they hit the Earth's atmosphere. Why doesn't the space shuttle?

    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? See more »
