Gradually, the liner problem was eroded to bureaucratic smoothness. And, towards the end of the shift, she was able to snatch a little personal time on the loop with Arkady.

Of course, the whole of the MCC would listen in, as would TsUP, the Russian mission control at Korolyov; in fact a smart IBM computer somewhere would transcribe every word they spoke. But there was still room for a little intimacy. This was one area where the Americans had found they had had a lot to learn from the Russians; those guys seemed to have a better instinct for the internal needs of the people they thrust up there into orbit.

So, thanks to Russian mission rules, Geena and Arkady were allowed their air time.

She read him a poem Arkady’s mother said he had always liked, called Poltav Battle. And then they sang together, her own toneless grunts along with Arkady’s voice — more musical, but reduced to a scratch by the loop — an old Russian song called On the Porch Together. She got the odd stare from her fellow controllers, but she couldn’t care less about that.

When she was done, she had a warm feeling which persisted even after her shift broke up.

She left the MCC, and made her way out of Building 30. She’d been intending to go straight to her car and home.

But she hesitated.

It was late afternoon. Spring: the least offensive period in Houston’s calendar. There was blossom on the trees, and there were, she saw, birds nesting in the big air-conditioning grilles on the side of the faceless concrete block that was Building 30.

She walked to the central quadrangle of the campus, concrete paths criss-crossing the bristly grass between the buildings. No doubt, she thought, there would now be trails of ducklings quacking their way across the campus, if the ducks hadn’t been chased out of JSC twenty years ago for the noise and mess they made. We ain’t here for ducks.

She remembered her promise to figure out the context for Henry’s precious Moon rock. She hesitated. Maybe the spring air was making her mellow.

She walked over to Building 2, Public Affairs, to find out how she could get hold of Jays Malone. It turned out he was coming in the next day, for a lecture and a tour of the lunar colony studies going on here at JSC. She talked her way into an invitation to join the party.

The next day, Geena made her way to the back of a lecture room in the PAO building, while Jays Malone fielded questions about his work from the scattered handful of journalists.
