Salvage in Space

His "planet" was the smallest in the solar system, and the loneliest, Thad Allen was thinking, as he straightened wearily in the huge, bulging, inflated fabric of his Osprey space armor. Walking awkwardly in the magnetic boots that held him to the black mass of meteoric iron, he mounted a projection and stood motionless, staring moodily away through the vision panels of his bulky helmet into the dark mystery of the void.
His welding arc dangled at his belt, the electrode still glowing red. He had just finished securing to this slowly-accumulated mass of iron his most recent find, a meteorite the size of his head.
Five perilous weeks he had labored, to collect this rugged lump of metal—a jagged mass, some ten feet in diameter, composed of hundreds of fragments, that he had captured and welded together. His luck had not been good. His findings had been heart-breakingly small; the spectro-flash analysis had revealed that the content of the precious metals was disappointingly minute.
