"the [science fiction] writer should be able to convince the reader (and himself) that the wonders he is describing really can come true...and that gets tricky when you take a good, hard look at the world around you."
- Frederik Pohl

| Impactor Determines Composition | ||
| 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, the sounding projectile from Mad Robot (1936) by Raymond Z. Gallun and iron fingers from The Death's Head Meteor (1930) by Neil R. Jones.
