A central goal of modern physics is the test of fundamental principles of nature with ever increasing precision. One of these contains of a differential measurement on freely falling ultra-cold clouds of two atomic species and thus using atom interferometry to test the weak equivalence principle in the quantum domain. By performing such an experiment in a weightless environment the precision of the interferometer can be considerably increased.
Here we demonstrate an apparatus for the first realization of a Bose-Einstein-condensate on a sounding rocket and its use as a source for atom interferometry in space. Its planned launch in November 2014 will be an important step towards the goal of placing high-precision atom-interferometric measurement devices in space.
