Aerospace engineering alum Clay Anderson, who has lived on the International Space Station (ISS) since last June, is preparing for his return to Earth in early November. The 48-year-old astronaut recently talked with Radio Iowa News about his feelings regarding the end of his space mission. While Anderson’s two Expedition 15 crewmates will leave on October 21 onboard the Soyuz, Anderson will continue his duties on the ISS as a member of Expedition 16 until his replacement arrives onboard the space shuttle Discovery. Discovery is scheduled to launch from Florida on October 23 and arrive at the ISS two days later. It will deliver a major addition, the Harmony Node, to the ISS.
