The lowest equivalent temperature reported in such a system is 38 pK with a free expansion time of 2 s, achieved in atom-chip-based magnetic traps in microgravity. Optical dipole trap (ODT) systems offer better optical access and the flexibility to condense both magnetic and non-magnetic atoms, but have not been used to prepare quantum degenerate gases under microgravity conditions.
