Geena had to shield her eyes to see the audience. She could see the platform on which the NASA TV cameras were mounted, and before it a thin scattering of journalists — mostly science correspondents, mostly men, mostly bearded, many of them familiar to her. This briefing wasn’t a formal press conference but had become a post-flight tradition; the idea was for the crew to come share their experience with colleagues and families. So there were engineers and controllers and mission managers from Mission Control and the science backrooms, here at Houston, and some pad technicians and managers from the Cape; but there were also grandmothers and little kids, relatives or friends of the crew.

There was nobody to see Geena.

That was her choice. Such events made her cringe, without her mother wanting to muscle in too.

It was a sparse crowd, and it looked as if today the audience was filled out with a tram-load or two of spectators from the Space Center, the flashy visitors” centre on the edge of the JSC complex. The gaggle of tourist types sat together in their slacks and T-shirts, cameras dangling from their necks.

At last the proceedings began.

First there was a long ceremony of team awards, presented corporate-style by the director of JSC. Every astronaut who flew got a “Spaceflight Medal” specific to the mission, pinned on her chest. When it was her turn, Geena got up to a ripple of polite applause, her palms sweating, suddenly as nervous as a grade school kid on show-and-tell day.

The Center director was a man called Harry Maddicott, somewhere in his sixties, hair slicked back, waistcoat stretched over an ample gut, fat and sleek and self-satisfied as a seal. He grinned at her as he pinned her medal to her suit jacket lapel, taking obvious care not to let his hands stray anywhere near her breast.

Next came the awards for the mission controllers, “outstanding performances” by the Flight Dynamics Officer and the Guidance, Navigation and Control Officer and even the Public Affairs Officer. There were awards for the guys who planned the EVAs, the mission’s spacewalks — even though the EVAs, which Geena had been scheduled to take part in, had both got cancelled because of a loose screw that stuck the Shuttle orbiter’s hatch mechanism.

Then, to Geena’s embarrassment, she was called up again. She was given an EVA credit because — Maddicott said — she and her partner had got suited up and taken to vacuum, even though they never left the vehicle, and that counted for the record. Then the mission commander got up and gave the two of them a special award: the balky screw, smaller than her thumbnail, that had fouled up the hatch. It was wrapped up in a plastic bag, for them to saw in half and mount on wood, half each.
