I had arranged with the current Bob-in-residence, a tenth-generation named Harvey, to have an android printed up from Howard’s most recent published set of plans. I could have done this visit remotely from Delta Eridani—or from anywhere in range of BobNet, really. But I wanted to actually come to Earth, to make the pilgrimage physically as well as emotionally. The Heaven-1B was currently in geosynchronous orbit, thirty-five thousand kilometers straight overhead.
