A fiery end? How the ISS will end its life in orbit
BBCHow the ISS will end its life in orbit Nasa Over the past two decades, the International Space Station has grown to an enormous 400 tonnes, so deorbiting it is a huge challenge Drift into the wrong part of the Pacific Ocean in eight years, and you might be in for a shock. "The space station has been a huge success," says Josef Aschbacher, the head of the European Space Agency, one of the more than a dozen partners in the programme. This will be the largest re-entry in history and, in March, Nasa asked Congress for funding to start development of a "space tug" that might be needed to perform the task – a spacecraft that can push the station back into the atmosphere. "Nasa is hedging its bets on Russian participation," says Wendy Whitman Cobb, a space policy expert from the US Air Force's School of Advanced Air and Space Studies. A Nasa spokesperson said the agency "welcomes proposals for new and innovative ideas" but at this time Nasa "has not called for nor received proposals to repurpose major structural parts of the International Space Station".
