Cassidy shaving his head

ISS036-E-004795 (29 May 2013) --- NASA astronaut Chris Cassidy, Expedition 36 flight engineer, gives himself a "serious" haircut in the Harmony node onboard the Earth-orbiting International Space Station. Cassidy, who has displayed his sense of humor more than once since coming aboard the orbital outpost in late March, ended up with a completely bald pate when this task was done. The three crew members due to come aboard the station later on this day include one -- Luca Parmitano of the European Space Agency -- who sports a similarly hairless head.
