The ex-army pilot, turned astronaut, from Wiltshire will take part in his first spacewalk from the International Space Station on January 15.
NASA has confirmed that Tim Peake along with fellow astronaut Tim Kopra will take part in a joint operation to replace a failed voltage regulator that affected one of the space station's 8 power channels in November.
Major Peake confirmed the announcement via Twitter.
Tim Peake lives and normally works in Wiltshire and used to be a test pilot with AgustaWestland in Yeovil.
He arrived on 15 December to begin a six-month mission on the complex.
