On January 15, 2016 American astronaut Timothy Kopra and British astronaut Timothy Peake performed the spacewalk. The astronauts began the spacewalk at 12:48 UTC. It was to be a six-and-a-half-hour spacewalk, the first so far this year. Flight controllers ordered two astronauts to terminate a spacewalk outside the International Space Station after one of them reported a small amount of water leaking into his space helmet. The EVA lasted 4 hours and 43 minutes.
