high-energy processing and containment facilities necessary for the manufacture and storage of antimatter.
    Stan knew the location of each spacecraft within his sphere of attention—from 100 kilometers above the Earth to the orbit of the Moon—whether they were in orbit or under thrust. His primary programming had him functioning as a kind of space traffic controller—not that collision was a major threat; usually, the only times ships were in danger of collision was during approach or departure from a space station or other orbital facility, and at those times, ship vectors and delta-V burns were the responsibility of the ship and station personnel and AIs.
    Still, there was considerable danger from the cloud of debris released by human activities in space since the beginning of the space age over a century before, everything from spent boosters and payload protective fairings to flecks of paint, which could be deadly if they impacted with, say, the visor of a pressure suit at several kilometers per second. Stan couldn’t track individual paint flecks, but his database of stray objects included things as small as two-centimeter bolts and a stray canister of exposed infrared film. Stan’s warnings of potential vector conflicts had resulted in 408 minor course corrections in the 12.37634912 years since his initialization. Space faring powers nearly always queried Stan on the possible outcome of specific boosts, vector changes, and time-distance-acceleration problems.
    The Chinese had stopped making such requests three months ago. Technically, by treaty they were required to announce all launches in advance, but the requirement was strictly one of courtesy, not enforcement.
    In fact, it was possible that they were operating their own deep-space tracking network. Stan was interested, however, in the politics of the situation. He did not understand the current tension between the Chinese and the newly created Confederation of World States, a loose trade and defense organization headed by the United States, Russia, and Japan that included all of the other space-capable powers. That such tension existed was self-evident from the news broadcasts of both sides, and from the fact that Stan’s secondary program tasks had increasingly involved surveillance of Chinese space assets for DODNET, the complex of AIs running much of the U.S. military’s command, control, and communications networks.
    There were, at the moment, no fewer than nineteen spacecraft of various types at KE26-GEO…most of them cargo craft boosted from Xichang. Two were the antimatter-powered cruisers Xing Shan (the Star Mountain ) and her sister ship, the Xing Feng (the Star Wind ). A third was a research vessel, the Tiantan Shandian , which DOD-NET translated roughly as the Heavenly Lightning .
    Stan had received numerous requests for updates on the Star Mountain ’s status in the past few weeks, and he’d dutifully passed on all observations. There had not been much to report; the huge spacecraft remained inert, though thermal and radiation readings suggested that its fusion power plant was being brought to full output, probably in anticipation of a launch. He could make out little detail, however; the Argus-Hera tracking satellites, of all his assets, came closest at periodic intervals to the Chinese facility—but that was never closer than some 20,000 kilometers.
    Still, standing orders required that any change in the status of either the Xing Shan or the Xing Feng be reported to the Pentagon at once .
    Now, though, three of his Argus-Heras had picked up the bright, hot flare of a burn at KE26-GEO. Interestingly, it was not the Star Mountain that was accelerating, but the much older Heavenly Lightning .
    The Lightning was listed as a deep space research vessel—415 meters long, massing 25,300 tons. The vessel was currently mounted on a two-stage stack, with a heavily modified Liliang ground-to-orbit booster as a
