But such an endeavor is no easy task, Chou points out. Why would he say that after the on-planet microgravity experiment? There was no solar radiation in his actual experiment where the cells died so why would he entertain that? Someone else should entertain that totally different experiment while he tries to gain support for expanding his experiment.
