This is a reusable craft made of compositematerial, 18 metres (60 feet) long and capable of taking six passengers and two pilots briefly into space before gliding back down to land.
Scientists at Harvard and MIT have invented self-folding sheets of compositematerial that can flex themselves into toy boats, tents and even paper airplanes.
