"No, you don't" Bessie said severely. "No, you don't. They need an alert, and I need to finish the programming on Sad Cow to be sure this thing doesn't wobble enough to shake us all apart. Even at a half RPM, your seams might not hold with a real wobble, and I don't like the idea of falling into a vacuum bottle as big as the one out there without a suit." "How much time do you need?" "On my mark, make it T minus thirty minutes. That ought to do it. O.K., here we go." There was a brief pause, then Bessie's voice came formally over the all-stations annunciator system. "Now hear this. Now hear this. All personnel. On my mark it is T minus thirty minutes to spin-out check. According to program, acceleration will begin at zero, and the rim is expected to reach .009 gee at one-half revolutions per minute in the first sixty seconds of operation. We will hold that spin until balance is complete, when the spin will slowly be raised to two revolutions per minute, giving .15 gee on the rim deck. "All loose components and materials should be secured. All personnel are advised to suit up, strap down and hang on. We hope we won't shake anybody too much. Mark and counting." Almost immediately on the announcement came another voice over the com line. "Hold, hold, hold. We've got eighteen hundred pounds of milling equipment going down Number Two shaft to the machine shop, and we can't get it mounted in less than twenty minutes. Repeat, hold the countdown." "The man who dreamed up the countdown was a Brain," Bessie could hear Mike muttering over his open intercom, "but the man who thought up the hold was a pure genius." "Holding the countdown." It was Bessie's official voice. "It is T minus thirty and holding. Why are you goons moving that stuff ahead of schedule and without notifying balance control? What do you think this is, a rock-bound coast? Think we're settled in to bedrock like New York City? I should have known," she muttered, forgetting to flip the switch off, "my horoscope said this would be a shaky sort of day." Chad Clark glanced up from his position at the communications console across the bridge from Bessie, to where her shiny black hair, cut short, framed the pert Eurasian features of the girl that seemed to be hanging from the ceiling above him. "Is it really legal," he asked, "using such a tremendously complicated chunk of equipment as the Sacred Cow for casting horrible scopes? What's mine today, Bessie? Make it a good one, and I won't report you to U.N. Budget Control!" "Offhand, I'd say today was your day to be cautious, quiet and respectful to your betters, namely me. However," she added in a conciliatory tone, "since you put it on a Budget Control basis, I'll ask the Cow to give you a real, mathematicked-out, planets and houses properly aligned, reading.
