The red letters in the panel said: "_First stage ends in five seconds._"

By the time he'd read it, the rocket hiccoughed and stopped. Then he

felt a surge of panic. He was falling! He had no weight! It was the

sensation of a suddenly dropping elevator a hundred times multiplied. He

bounced out of the depression in the foam-cushion. He was prevented from

floating away only by the straps that held him.

There was a sputter and a series of jerks. Then he had weight again as

roarings began once more. This was not the ghastly continued impact of

the take-off, but still it was weight--considerably greater weight than

the normal weight of Earth. Cochrane wiggled the foot that had gone to

sleep. Pins and needles lessened their annoyance as sensation returned

to it. He was able to move his arms and hands. They felt abnormally

heavy, and he experienced an extreme and intolerable weariness. He

wanted to go to sleep.

This was the second-stage rocket-phase. The moon-rocket had blasted off

at six gravities acceleration until clear of atmosphere and a little

more. Acceleration-chairs of remarkably effective design, plus the

pre-saturation of one's blood with oxygen, made so high an acceleration

safe and not unendurable for the necessary length of time it lasted.

Now, at three gravities, one did not feel on the receiving end of a

violent thrust, but one did feel utterly worn out and spent. Most people

stayed awake through the six-gravity stage and went heavily to sleep

under three gravities.

Cochrane fought the sensation of fatigue. He had not liked himself for

accepting the orders that had brought him here. They had been issued in

bland confidence that he had no personal affairs which could not be

abandoned to obey cryptic orders from the secretary of a boss he had

actually never seen. He felt a sort of self-contempt which it would have

been restful to forget in three-gravity sleep. But he grimaced and held

himself awake to contemplate the unpretty spectacle of himself and his

actions.
