Don Quixote on cosmic rescue mission

Mythical Spanish knight Don Quixote, famed for charging at windmills he mistakes for enemies, is to ride again on a cosmic mission to save the world.
The European Space Agency has given high priority to a Spanish project which aims to attack an approaching asteroid to see whether spacecraft can deflect a body that may in future be on a collision course with earth.
Two craft will set out — one named after the valiant knight of Cervantes’ classic tale, the other after his long-suffering servant Sancho Panza.
