His regular morning call to Mission Control was scheduled for 0800, as usual. And after that he was supposed to see the station doctor for his weekly exam. Like most fliers, Dan Tighe did not trust doctors, not even attractive female doctors. He rummaged through the small cabinet built into the corner of his office where the curving shell of the module met the forward bulkhead. His face, red and chafed, was set in a grim scowl of determination.

It was a face built of contradictions: finely sculpted cheekbones and a hawk’s nose that had been broken long ago when he had crash-landed a crippled jet fighter. Strong stubborn jaw with a mouth that seemed almost too small for it, lips as thin and sensitive as a poet’s. He kept his dark brown hair short enough to meet the old military regulations, but combed it forward to conceal his receding hairline. The gray at his temples bothered him, even though women called it distinguished.

And the eyes: electric blue, vital, brilliant. The eyes of an eagle, a flier, probing incessantly, never still, never satisfied. But now they were wary, guarded, the eyes of a man who had been defeated and banished. The eyes of a man who wanted to be alone in the cockpit of a nimble supersonic jet, but found himself smothered in the responsibilities of commanding a glorified schoolhouse that plodded along a fixed and calculated orbit—and in danger of losing even that.

A small bonsai bush trimmed into the shape of a bird floated at the end of a tether attached to the wall of his cramped office. Tighe whispered to it, “Sorry, no time for you this morning,” and gently pushed it out of his way as he searched through the Velcro-lined shelves of the narrow cabinet.

At last he found what he was looking for: the blood-pressure cuff. With a grunt of satisfaction he rolled up the left sleeve of his coveralls and wrapped the plastic around his biceps. Taking a deep breath that was supposed to calm him, he inflated the cuff and then read off the glowing digital numbers on its tiny electronic display: 163 over 101. The readout was adjusted for the effects of microgravity. Not bad, he thought. But not good enough.
