She — along with the rest of the astronaut pool — had to return to Houston by the next flight, for a meeting with Muldoon.

It was an unusual request, even unprecedented. But she knew what it had to signify.

She got out of her tub and began toweling herself off. She could feel her heart thumping a little faster, and it had nothing to do with acceleration.

Ares. It’s beginning.

By the time York arrived, the small conference room on the third floor of Building 4 was crowded. Joe Muldoon sat isolated at a small desk on a stage at the front of the room; he was riffling through Vu-graph foils.

York pushed through a forest of sports-shirted male astronauts and found a seat near the back of the room. A man who had flown around the Moon sat down next to her.

Muldoon must know, York thought, that he had every person in the room by the metaphorical balls.

One of the many things she speculated about regarding the mysterious crew selection process was whether men like Muldoon actually enjoyed wielding their power. Looking at Muldoon, his foot tapping nervously on the stage, his shoulders knots of tensed-up muscles, she somehow doubted it.

Which, as far as she was concerned, was all to his credit.

All around her there was a babble of conversation, lively, deep-throated, maybe a little nervous. There was a kind of competitive cheerfulness in the air. Like none of this really mattered. Oh, it’s only the crew rota for the most significant new program of flights in years. Hey, you catch the ball game Monday?

Then Muldoon got to his feet and stood with his hands on his hips, facing the astronaut corps. Blue-eyed, his sharp crew cut graying blond, he looked like a caricature of a drill sergeant, York thought.

The remnants of conversation died off immediately, leaving Muldoon facing rows of silent faces.

Muldoon spoke without a mike, without preamble, and his words carried to every person in the room. “The guys who are going to be the first to fly to Mars are right here, in this room.”

“You’ve heard by now we have a first cut of Ares mission profiles.”

He snapped on the Vu-graph projector, and an image was thrown up on a screen behind him; it was a simple list, typed and copied onto the foil. “We’ve got eight flights here, both manned and unmanned. We’ve defined six preliminary classes of mission, designated here A to F. They are mostly Earth-orbit tests of the system components. But they lead up to the final flight — mission class F — which will be the full Mars landing attempt.

“You can see from the foil that the two A-class missions will be unmanned shakedown tests of the new Saturn VB booster system, carrying boilerplate Apollos and MEMs. The B mission will be the first manned flight to Earth orbit — or maybe lunar orbit — to man-rate the Saturn VB. A live Apollo, obviously, but a boilerplate MEM again. The C mission is another unmanned shakedown, this time of a MEM test article in near-operational condition. The D mission will be the first manned MEM flight, to Earth orbit; this will be a long-duration mission to test for space soak.
