In minutes, the space tug had a line made fast. In half an hour, the two space craft were bound firmly together, but far enough apart for the rocket blasts to dissipate before they reached the Moonship. Mike returned to the tug. A pair of the big Mark Twenty rockets burned frenziedly in emptiness. The Moonship was slowed by a fraction of its speed. The deceleration was hardly perceptible. There were more burnings. Back on Earth there were careful measurements. A tight beam tends to attenuate when it is thrown a hundred thousand miles. It tends to! When speech is conducted over it, the lag between comment and reply is perceptible. It's not great--just over half a second. But one notices it. That lag was used to measure the speed and distance of the two craft. The prospect didn't look too good. The space tug burned rocket after rocket after rocket. There was no effect that Joe could detect, of course. It would have been like noticing the effect of single oar-strokes in a rowboat miles from shore. But the instruments on Earth found a difference. They made very, very, very careful computations. And the electronic brains did the calculations which battalions of mathematicians would have needed years to work out. The electronic calculations which could not make a mistake said--that it was a toss-up. The Moon came slowly to float before the two linked ships. It grew slowly, slowly larger. The word from Earth was that considering the rockets still available in the space tug, and those that should have been fired but weren't on the Moonship, there must be no more blasts just yet. The two ships must pass together through the neutral-point where the gravities of Earth and Moon exactly cancel out. They must fall together toward the Moon. Forty miles above the lunar surface such-and-such rockets were to be fired. At twenty miles, such-and-such others. At five miles the Moonship itself must fire its remaining fuel-store. With luck, it was a toss-up. Safety or a smash. But there was a long time to wait. Joe and his crew relaxed in the space tug. The Chief looked out a port and observed: "I can see the ring-mountains now. Naked-eye stuff, too! I wonder if anybody ever saw that before!" "Not likely," said Joe. Mike stared out a port. Haney looked, also. "How're we going to get back, Joe?" "The Moonship has rockets on board," Joe told him. "Only they can't stick them in the firing-racks outside. They're stowed away, all shipshape, Navy fashion. After we land, we'll ask politely for rockets to get back to the Platform with. It'll be a tedious run. Mostly coasting--falling free. But we'll make it." "If everything doesn't blow when we land," said the Chief.
