NASA has agreed to consider a Boeing proposal to extend the first piloted test flight of its commercial CST-100 Starliner crew capsule from two weeks to up to six months with an extra crew member for the International Space Station, hedging against potential delays that could jeopardize U.S. crew access to the orbiting outpost.
