Gravity, we
have defied you. Seven university student teams from across the United States
escaped the pull of Earth's gravity — if only for a few seconds — on a NASA
microgravity flight to see how fire, liquids and magnets behave in weightlessness.
The students flew with
NASA's Microgravity University Program Friday (July 19) aboard a Zero Gravity
Corporation Boeing 727 jet modified to fly up and down on a parabolic path to
create up to 30 seconds of zero gravity, moon gravity or Martian gravity on the
downswing followed by periods of "hypergravity" (twice Earth's pull)
on the way back up.
