I didn’t actually get a look at the Excelsior until I’d been set up inside. It was a duplicate, of course, of the Coraggio. But I hadn’t actually seen it before that afternoon. The VR-2 has an awkward appearance. It consists primarily of a hull with three massive heat sinks running almost its entire length, a pair of exhaust tubes, and two fusion-powered drive units. Its prow resembles a large block with rounded edges. This was the shield, designed to protect the vehicle from rocks and dust. The grapplers are housed inside the shield. They’re used to catch and secure an asteroid, which becomes the source of hydrogen and propellants for the fusion drive; they also provide more security against stray particles. When you’re moving at thousands of miles per second, even a bit of dust can sting.
(I should mention that, at the time when Lucy went missing, nobody had yet gotten to a thousand miles per second, though the Coraggio had reached eight hundred sixty-five per second.)
Morris liked to remind me that running a simulation is nothing like experiencing the real thing. He has that exactly right, though probably not in the way he meant. He was thinking of the pressures generated by acceleration or course changes. But I think he was missing something. It’s true that, on board a ship, I have no sense of movement other than the incoming data. But I feel an enormous difference when I’m actually in the pilot’s seat, so to speak: I can feel the power of the engines.
It’s psychological. Of course that shouldn’t be happening since everyone assures me I don’t have a psychological function.
The Excelsior was located about a mile from the space station Liberty, silhouetted against a curving rim of white clouds. It was the first time I’d been in orbit since my Coraggio flight. When I’d gotten back on that occasion, a voice from the station had said Welcome home, and I’d thought how great it was. Everyone had been so excited. They’d extracted me from the ship and taken me down to the space center for a celebration. I even got to say a few words about how proud I was, what an honor it had been, and so on.
Then they moved me to Huntsville, and I started answering phones and seeing to the air conditioning.
I’ve often thought that humans are fortunate in having a mobile capability. It provides the option to get up and walk out.
“Excelsior. This is Liberty. Launch in ten minutes.”
“Roger that,” I said. I love being able to talk like an astronaut.
I started the engines. Checked all systems. And waited.
Finally: “Excelsior, clear to go.”
I set the clocks at midnight, eased away from the space station, turned onto my heading, took a final look at my energy levels, and began to accelerate. I didn’t feel any effects, of course. But I remembered Morris’s comment when I took out the Coraggio last year: “You literally roared out of town, baby.”
“Liberty,” I said, “this is Excelsior. Under way.”
“Copy that, Sara.”
I didn’t know who was manning the ops desk in the space station, but I decided I liked him.
I was accelerating at almost twice the rate I’d used on my previous mission. By the end of the first hour, the Excelsior had reached eighteen miles per second.
Even though there were no human passengers, the ship did have a cockpit. Two chairs were positioned for use by a pilot and whoever else might be along. In my experience, they’d been used exclusively by technicians. I tried to imagine Morris in one of them, enduring that acceleration. And, coincidentally, while that was running through my mind, he called.
“How you doing, Sara?”
“I’m good, boss. Wish you were with me.”
“In a way, I am. I assume you’ve had no problems?”
“Negative. Not a thing.”
“Okay. Have a big time.”
“I plan to.” Neither of us knew quite what to say. I’d be gone for at least four months and I wanted to tell him I’d miss him. But the world was listening, and I didn’t want to give everybody a laugh line. Not at Morris’s expense, anyhow. I thought about asking who was answering the phones now that I was gone, but I let it go.
At about 0300 I passed the Moon. At 0829 I hit five million mph. Liberty called, wanting to know about fuel consumption. We were doing better than anticipated.
There was a delay of about a minute. Then they were back: “Excelsior, you are go for Starbright.”
Starbright was the name they’d given Minetka. They had a tendency to overstate things when they named projects. “Copy that,” I said.
I thought they were finished, but a few minutes later the voice returned: “Be advised solar activity is currently higher than normal. It is expected to increase over the next few hours, but it shouldn’t present a problem for you.”
Nothing more was scheduled until midnight the following day. Until then we’d continue to accelerate. Then I’d shut the engines down and we’d go into cruise mode for two months. When the Excelsior got within range of Minetka/Starbright, I’d need another two days to brake.
I ran a second systems check. That was unnecessary really; an alarm would alert me to any likely problem. But I was a captain again and I enjoyed the role, which I played to the hilt.
I would have liked to wander around the Excelsior in uniform, soliciting reports from my crew the way they did in the science fiction films. And welcome a few passengers on board. Glad you chose Brightstar Transport, ladies and gentlemen. We hope you enjoy the trip. Beverages will be served as soon as we reach cruising speed …in another day and a half.
Actually, there wouldn’t have been much space available for visitors.
Later that first evening, Liberty called again. It was Morris. “How you doing, Sara?”
“Need a chess partner, Morris.” Actually he didn’t play chess. But he understood.
I was pretty sure Calkin frowned on Morris’s inclination to talk informally with me. He undoubtedly saw it as a character flaw, a weakness. It was something lower-level employees do, and Calkin would have thought that Morris was demeaning himself, or maybe worse if he was actually listening to our exchanges.
I had to wait almost four minutes for his response. “Mary’s coming for the weekend, with Adam and Mike.” His wife and kids. Erika had fought her way back after the accident, and had returned to college. “We’ll be looking for a place.” I wondered whether he’d be buying, since NASA’s future was so uncertain. “When we get settled, we’ll have you over. Make a party of it.” That was the kind of remark guaranteed to get him in trouble with Calkin. He’d think Morris was losing his mind.
“Adam will want something on the beach,” I said. The time delay meant nothing to me, of course. But I could imagine Morris, hooked up from his office (where it was close to noon), trying to keep the conversation coherent.
Standard operating procedure required me to check in twice daily. I complied, informing Liberty each time that everything was on schedule.
I was still accelerating on the second day when I passed the orbit of Mars. The Excelsior had gone seventy-two million miles when, at midnight of Day 2, I finally shut the drive down and we went into cruise mode.
I could have put everything on automatic and gone to sleep at that point, waking when we got into the vicinity of Minetka, or when we received a transmission, either from Liberty or, if we were very lucky, from Lucy. But I couldn’t bring myself to do that. Even though I took no pleasure in being alone in that ship, I knew I would not get there again, and I could not rationalize throwing my chance away. The day would come when I would wish very much to come back, to live again in the Excelsior’s cockpit, riding through the night. So I stayed awake. I asked Liberty to forward some radio programs, which they did. They knew I enjoyed the talk shows, so they kept me well-supplied with them. I even heard my own voice talking with the space station. “Everything on schedule.” “All systems five by.” “Saw an asteroid today.” Nothing very exciting.
