This blog is written by Carolyn Kierans and Clio Sleator. We are both physics PhD students at UC Berkeley working under Dr. Steven Boggs on the Compton Spectrometer and Imager (COSI). We use this space during our balloon campaigns to keep our family, friends, and colleagues at home happy and up to date with the goings-on of COSI.
