Abstract :
Designs for planned space clock missions are described. The cold collision shift and multiple launching (juggling) have important implications for the design and the resulting clock accuracy and stability. In a recent fountain experiment, we have demonstrated some of the trapping and cooling techniques for our design of a microgravity clock
