Schwerelosigkeit simulieren.<br />

The drop tower in the Centre of Applied Space Technology and Micro -<br />

gravity (ZARM) is used by Bremen’s scientists to simulate gravity.<br />

SCIENTIFIC EXCELLENCE<br />

Expertise from the drop tower to the marine world: the<br />

State of Bremen is a key research location in Germany,<br />

with cooperation as one of its strengths.<br />

From 0 to 170 kilometres per hour in 0.2 seconds: no<br />

sports car can do that. But Torsten Lutz and his colleagues<br />

in the Centre of Applied Space Technology and Micro -<br />

gravity (ZARM) at the University of Bremen manage this<br />

crazy acceleration every day. “In fractions of a second, a<br />

catapult flings a capsule up at this speed in our 146 metre<br />

high drop tower; on reversing direction it then comes<br />

back down again just as quickly”, says the engineer. The<br />

reward for all this effort is the weightlessness generated in<br />

the capsule during this process. Scientists then have maximum<br />

9.3 seconds to perform experiments without being<br />

subject to gravity. This is enough time to research new<br />

combustion processes or fluid mechanical phenomena,<br />

and costs far less than booking experiment time in the<br />

international space station ISS.<br />

Bremen’s drop tower is the most striking symbol of science<br />

in the State of Bremen and characteristic for the way sci-<br />
