British astronaut Tim Peak held a press conference at the European Astronauts Centre in Cologne, Tuesday. It was Peake's first press conference since his return to Earth from a six-month International Space Station (ISS) tenure. Peake was part of Expedition 47 that returned on Earth on June 18, aboard the capsule of the Soyuz TMA-17M spacecraft, along with NASA astronaut Tim Kopra and Russian cosmonaut Yuri Malenchenko. While aboard the ISS, Expedition 47 crew members partook in various experiments in biology, physical science and biotechnology.
