Nasa sought names to be stencilled in microscopic lettering onto three fingernail-sized silicon chips fitted to a plaque on the robot. Louis, Aila, Mallie and Rannoch - four ospreys from Loch Arkaig Pine Forest - are among the 10.5 million names. The names have been given to the four ospreys by conservationists and birdwatchers.
