Jian-Rong Gao will be giving a lunch lecture on two space projects the TU Delft is working on, in collaboration with NASA. The arctic balloon mission GUSTO will explore the far-infrared [OI], [CII] and [NII] lines in the Milky Way and a nearby companion galaxy. Stratospheric Terahertz Observatory (STO-2) on the other hand, is a NASA-funded long duration balloon experiment designed to address a key problem in modern astrophysics: understanding the life cycle of star-forming molecular clouds in our Milky Way Galaxy.
