The CODAG (COmet Dust Aggregation) -Experiment was flown on the Space Shuttle Discovery in October 1998.CODAG is a German experiment headed by Dr. Jügen Blum at the University of Jena - the Laboratory for Astrophysics built the Light Scattering Unit |

CODAG is a microgravity experiment
to shed light on a how dust particles come together at the beginning of
planetary creation to form comets and other planetesimals. The experiment
is designed to test theoretical models of how dust grows by aggregation
and how light propagates through a solar nebula of gas or dust.
