What do music ensembles and human spaceflight have in common? They require the harmonization of different elements to create an inspiring opus. NASA’s Paige Whittington has experience with both. As a principal flutist for Purdue University’s Wind Ensemble, Whittington helped fellow flutists play beautiful music together while pursuing her graduate degree. Now, as a space [...]
