In these gravity experiments you will be creating and testing different types of parachutes. Astronauts had to use parachutes to slow their capsules down so they could land in the ocean without being killed before space shuttles were built that could return to land. The parachutes slowed their entry enough so their space capsules did not break apart when they hit the water in the ocean.
Testing your parachute
Scientists conducted many gravity experiments as they tested different parachutes to slow large objects down. Space capsules returning to Earth during early space explorations were traveling too fast to land safely as they returned to Earth so they needed parachutes.
Parachutes in the space capsules opened and reduced the space capsules speed of reentry. The air resistance of the huge umbrella shaped parachutes slowed the space capsules as the gravity tried to accelerate the speed of reentry. The parachutes slowed their return to Earth enough to safely splash down in the ocean.
Ships were waiting nearby to pick up the returning astronauts. Parachutes are also used to slow down high speed race cars on the Bonneville Salt Flats after they set land speed records.
