"To get anywhere, or even live a long time, a man has to guess, and guess right, over and over again, without enough data for a logical answer."
- Robert Heinlein

| The use of an impactor to smash into a small celestial body; watching the impact can determine the composition of the small body. |
Explorers from a Martian colony encounter what appears to be a small asteroid. How can you tell what it is made of without actually landing and taking samples?
| "There it is. Can you get a spectro?"
"No heat." Wendis shook his head. "I'll have to warm it up with a tracer." Fire streaked in a thin line from the muzzle of a cannon-like tube mounted beneath the viewing instruments and a tiny, rocket-powered projectile, drove towards the mysterious bulk. It hit, exploding into a cloud of incandescent vapour, and Wendis stared thoughtfully at the brilliant lines on the spectroscope screen. "... the spectro shows traces of iron, some copper, a little tungsten and a lot of beryllium. Looks unnatural somehow, too much like an alloy." |

As it turns out, it's not an asteroid at all.
The recent Deep Impact program, in which a comet's composition is investigated with the aid of an 850 pound impactor, now seems like a modern incarnation of an old idea.
Compare to the Spectro-Flash Analysis from Salvage in Space (1933) by Jack Williamson.
