Guppy began applying course corrections, with the changes registering on the schematic in real time. I watched the display absently, while I weighed my options. If necessary, I was prepared to let the drive go down with the iceberg and just build a new one. For a smaller chunk of ice, I’d have just shrugged and let it sail on past the planet, but this baby was huge. I could lose every other incoming chunk for the next six months while I built a new drive, and still come out ahead.
