The weightless drifting reminded him they had a time limit on returning to gravity conditions.

Instantly they felt their bodies start to rise or twist under zero gravity conditions.

The only real difference ( some consider it an advantage) is the zero gravity condition prevailing in space.

The scientific goal was to determine how Listing's Plane is altered under various gravity conditions.

It is usually used under zero gravity conditions.

Had they been working under even some slight gravity conditions, they might have had a chance.

Facilities using diamagnetism may prove workable for laboratories simulating low gravity conditions here on Earth.

Fliers get to experience the gravity conditions - or the lack thereof - of being in outer space.

In freefall, the situation was even worse than it would have been under gravity conditions.
