The people behind Cassini's Composite Infrared Spectrometer (CIRS) reflect on their years-long experience working with their team - relationships formed, children born, challenges conquered, and their feelings as the Cassini mission comes to an end. CIRS was built and is operated at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Cassini is making its final dive into Saturn on September 15, 2017.
