  • Up, up and away. High-altitude balloons called Stratollites might soon be giving the US military and NASA permanent and relatively low-cost eyes in the sky over any part of the planet they want. Developed by US firm World View, Stratollites are uncrewed hydrogen or helium-filled balloons that tour the stratosphere at between 10 and 46 kilometres up, with cameras and sensors on board. As the wind in each layer of the stratosphere blows in a different direction, a Stratollite's path can be changed simply by moving to a different height and hitching a ride. The balloons are controlled from the ground. The firm released images from one Stratollite this month with a resolution of half a metre.
