Hiro came over just as the Russian was finishing. "Maybe she has some hard data, Toby; she's a physical chemist, remember." It was strange to hear him acoustically, not as bone vibration from the implant.

"Everything's hard up there, Hiro." "Don't I know it?" He was feeling it, too, that special buzz. We couldn't quite seem to make eye contact. Before the awkwardness could deepen, he turned and gave one of the yellow clowns the thumbs up.

Two of them helped me into the Bauhaus coffin and stepped back as the lid hissed down like a giant's faceplate. I began my ascent to Heaven and the homecoming of a stranger named Leni Hofmannstahl. A short trip, but it seems to take forever.

Olga, who was our first hitchhiker, the first one to stick out her thumb on the wavelength of hydrogen, made it home in two years. At Tyuratam, in Kazakhstan, one gray winter morning, they recorded her return on eighteen centimeters of magnetic tape.

If a religious man one with a background in film technology had been watching the point in space where her Alyut had vanished two years before, it might have seemed to him that God had butt-spliced footage of empty space with footage of Olga's ship. She blipped back into our space-time like some amateur's atrocious special effect. A week later and they might never have reached her in time; Earth would have spun on its way and left her drifting toward the sun. Fifty-three hours after her return, a nervous volunteer named Kurtz, wearing an armored work suit, climbed through the Alyut's hatch. He was an East German specialist in space medicine, and American cigarettes were his secret vice; he wanted one very badly as he negotiated the air lock, wedged his way past a rectangular mass of airscrubber core, and chinned his helmet lights. The Alyut, even after two years, seemed to be full of breathable air. In the twin beams from the massive helmet, he saw tiny globules of blood and vomit swinging slowly past, swirling in his wake, as he edged the bulky suit out of the crawlway and entered the command module. Then he found her.
