Nasa Gravity Free Room

The facility is used by investigators from around the world to study the effects of microgravity on physical phenomena such as combustion fluid physics biotechnology and materials science.

Nasa gravity free room.

It is the gravity in space that keeps neptune rotating around the sun and what keeps the sun glued to our galaxy. Objects with more mass have more gravity. If gravity was nonexistent in space the moon some 400000 km away wouldn t revolve around us constantly. Watch the visualization for a tour of earth s gravity field.

The question is how does nasa achieve this. Anything that has mass also has gravity. See our zero g which puts test payloads into a free fall for 5 seconds dropping over 400 feet. All its mass makes a combined gravitational pull on all the mass in your body.

Earth s gravity comes from all its mass. The facility can provide a microgravity test environment for a fraction of the cost conducting an experiment in space and provides the best gravity levels of any of nasa s ground based low gravity facilities. The zero gravity facility is nasa s premier facility for conducting ground based microgravity research. Since 2002 nasa s twin grace satellites have mapped earth s gravity the attractive force exerted by its mass enabling scientists to see these differences and monitor how they change over time.

Gravity also gets weaker with distance. The word zero is very misleading here.
