Tim is the first British astronaut to work with the European Space Agency (ESA), and the second astronaut to wear a British flag badge. After finishing school, Tim joined the Royal Military Academy Sandhurst, and became a lieutenant in the Army Air Corps, and eventually a captain.
He trained as a helicopter pilot and a test pilot, before joining ESA's astronaut training program. As part of the training, the astronauts lived in a cave system in Italy, to prepare for the isolating and extreme conditions of living in space. Tim and his crew also trained in an underwater laboratory, becoming aquanauts (after spending over 24 hours underwater).
In December 2015, Tim was launched to the International Space Station in a mission called Principia. When he returned to Earth in June 2016, he had completed around 3000 orbits of the Earth, and travelled a distance of 125 million kilometres.
