ISS Astronauts Celebrate 'Cosmos' with Weightless Experiment in Space Station - Video

The new "Cosmos" science TV series on Fox has received an out-of-this-world from astronauts on the International Space Station in a new video showing how weightlessness works.

In the new video beamed from space, NASA astronaut Rick Mastracchio considers Isaac Newton's third law of motion - every action produces an equal and opposite reaction - and demonstrates how this works in microgravity, 260 miles (418 kilometers) above Earth.

To demonstrate this, Rick Mastracchio pushes his colleague and ISS Commander, Japanese astronaut Koichi Wakata, along with a model of NASA's now-retired space shuttle.

As Wakata and the model spacecraft float forward, Mastracchio drifts backwards.

"This is simple science but the more complex science we're doing here on the space station will help us bring real world benefits back to humanity on Earth, as well as take us further into the cosmos than ever before, including to an asteroid, the moon or on to Mars," Mastracchio said.

Astrophysicist Neil deGrasse Tyson, host of "Cosmos: A Spacetime Odyssey," introduced the video of his "friends in high places," saying, "when you're doing science, you have to do experiments."
