But that was the day the Russians launched an unmanned space-probe headed toward M-387. That development may have influenced Holmes to do as Burke asked. Later on, it transpired that the probe originally had been designed and built as a cargo-carrier to take heavy loads to Earth's moon. The Russian space service had planned to present the rest of Earth with a _fait accompli_ even more startling than the first Sputnik. They had intended to send a fleet of drone cargo-rockets to the moon and then assemble them into a colony. Broadcasts would triumphantly explain that the Soviet social system was responsible for another technical achievement. But to get a man out to M-387 was now so much more important a propaganda device that the cargo-carriers were converted into fuel-tankers and the first sent aloft. At ten thousand miles up, when the third booster-stage should have given it a decisive thrust, one of the probe's rocket engines misfired. The space-probe tilted, veered wildly from its course, and went on accelerating splendidly toward nowhere. And still the steady, urgent beeping sounds continued to come to Earth, with every seventy-nine minutes a broadcast containing one section of crackling sounds and a tone of extremest urgency. The day after the probe's ineffectual departure, Burke got back to his plant. He brought Holmes with him. Together, they looked over the accumulated material for Burke's enterprise and began to sort out the truckloads of plaster of Paris, masses of punched-sheet aluminum, girders, rods, beams of shining metal, cased dynamos, crated pumps, tanks, and elaborately padded objects whose purpose was not immediately clear. Sandy was overwhelmed by the job of inventorying, indexing, and otherwise making the material available for use as desired. There were bales of fluffy white cloth and drums and drums of liquids which insisted on leaking, and smelled very badly when they did. But Burke found some items not yet on hand, and fretted, so Sandy brought her sister Pam into the office to add to the office force. Sandy and Pam worked quite as hard in the office as Burke and Holmes in the construction shed. They telephoned protests at delays, verified shipments, scolded shipping-clerks, argued with transportation-system expediters, wrote letters, answered letters, compared invoices with orders, sternly battled with negligence and delays of all kinds, and in between kept the books of Burke Development, Inc., up to date so that at any instant Burke could find out how much money he'd spent and how little remained. The two girls in the office were necessary to the operations which at first centered in the construction shed, but shortly began to show up outside.
