"My feeling is that the chance of our surviving into the twenty-first century as working civilization is less than fifty percent but greater than zero."
- Isaac Asimov

Meteor Warning System  
  A system that provided rockets in flight with early warning of meteors.  

This is an early idea to work with a problem that is a concern today to space scientists. Not so much meteors, but other junk in orbit around Earth.

Rockets to the number of a hundred were under construction, embodying all the lessons Drake's disastrous expedition had learned. Instruments, to give warning of meteor swarms by means of magnetic fields projected ahead, were devised.
From A Conquest of Two Worlds, by Edmond Hamilton.
Published by Wonder Stories in 1932

Obviously, this method depends on high ferrous metal (or other magnetic metal) content of incoming meteors. Unfortunately, not all meteors have a high metal content.

Technically, "meteor" refers more to the streak of light seen at night when a solid, natural body streaks into the atmosphere. The object itself is called a meteoroid; any part that survives to reach the ground is called a meteorite. When a bright meteor is seen to explode, it is called a bolide.
