Getting out of his seat once the Clippership had made rendezvous with the transfer rocket was sheer torture. Eberly kept his head rigidly unmoving, his fists clenched, his eyes squeezed down to slits. To the cheerful commands of the flight attendants, he followed the bobbing gray coveralls of the woman ahead of him and made his way along the aisle hand over hand from one seat back to the next until he glided through the hatch into the transfer vehicle, still in zero gravity, gagging as his insides floated up into his throat.

No one else seemed to be as ill as he. The rest of them — fifteen other men and women, all department leaders as he was — were chatting and laughing, even experimenting with allowing themselves to float up off the Velcro carpeting of the passenger compartment. The sight of it made Eberly’s stomach turn inside out.

Still he held back the bile that was burning his throat. I will not give in to this, he told himself over and over. I will prevail. A man can accomplish anything he sets his mind to if he has the strength and the will.

Strapped down again in a seat inside the transfer rocket, he stared rigidly ahead as the ship lit off its engines to start its flight to lunar orbit. The thrust was gentle, but at least it provided some feeling of weight. Only for a few seconds, though. The rocket engines cut off and he felt again as if he were falling, endlessly falling. Everyone else was chattering away, several of them boasting about how many times they had been in space.
