Nasa Gravity Free Room

Anything that has mass also has gravity.

Nasa gravity free room.

So the closer objects are to each other the stronger their gravitational pull is. All its mass makes a combined gravitational pull on all the mass in your body. It is the gravity in space that keeps neptune rotating around the sun and what keeps the sun glued to our galaxy. The word zero is very misleading here.

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. If gravity was nonexistent in space the moon some 400000 km away wouldn t revolve around us constantly. The question is how does nasa achieve this. The zero gravity facility is nasa s premier facility for conducting ground based microgravity research.

This is accomplished by allowing the experiment vehicle to free fall in a vacuum a distance of 432 feet 132 m. Earth s gravity comes from all its mass. 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. Watch the visualization for a tour of earth s gravity field.

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. Explore nasa s drop zone zero gravity research facility nasa.
