"[Science fiction] has become big business, where books are merchandised and promoted and distributed and placed on sale like slabs of bacon or cans of soup."
- 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.

'... making the point that their likenesses, every move they made, were being transmitted.'
'But the stars are only atoms in larger space, and in that larger space the star-atoms could combine to form living matter, thinking matter, couldn't they?'
'...to build up a video picture would require, say, ten million decisions every second. Mike, you're so fast I can't even think about it. But you aren't that fast.'
'The area affected was five hundred kilometres across, and perfectly circular.'
'Hasan always pitched a Gauzy - a one-molecule-layer tent, opaque, feather-light, and very tough.'
'And he had been sent with troops, supplies and bombs to command Russia's most trusted post, the Moonbase.'
'What is your population', I asked. 'About eighty millions.'
