Experiments in Zero-gravity |
Parabolic
Flights: To know how things behave in space
In
order to be able to check equipment and experiments as if they were
in space, you have to find a way by which you can get rid of gravity,
which keeps your feet on the ground. The only possibility is in
fact to have a vehicle in free fall, same as in space.
One
of the vehicles you can use is the airplane, by having what we call
"parabolic flights". The aircraft climbs with an angle of 45°, then
the pilot cuts the motors and the plane start a "free fall", in
fact following a path that is a parabola as if a stone was thrown
to the sky. During that phase everything in the plane floats, the
experiments and the people, they are in "zero-G"
When the descent angle is 45° (everything goes towards the ground
at the end like the stone, the initial speed being not large enough
to go in orbit), the pilot puts the motors on again and prepares
for a new parabola. The pilot does that several times during a flight.
ESA give a few lucky students (120 per year) the chance to fly with
their experiments on one of these flights so that they can test
and see what is happening in a real spacecraft when there are no
rockets firing. If you want to know more, just go to http://www.estec.esa.nl/outreach/pfc/.
Below are some examples, with pictures, of previous student experiments.
