The astronauts inside the International Space Station are shown in the footage what happens when the ship fires its thrusters.

It's cool on its own, but it's also a great demonstration of physics. The video that the European Space Agency posted to YouTube shows the crew in microgravity, but the astronauts are not moving inside.

During the maneuver, the astronauts inside the station keep flying at the same speed and direction.

The maneuver is exciting because it is the first mission for the crew of the space station, and they will have to wait for the space station to move so they can tuck their knees in.

The video may lend credence to the idea that Russia's head cosmonaut left because there wasn't enough work for him to do on the International Space Station. It's reasonable to think that crew on various teams are working overtime to fill up their downtime.

It still puts a smile on your face despite the cultural implications of the clip, such as the fact that war is affecting life in space. The basic human experience of creating fun is unlikely to disappear wherever we are.

Scientists propose a planted-size telescope.
