"And a navigator," Johnny added. "Don't sell your brother short." "Fat chance of that. Greg would never stand for it." Johnny frowned. "You lads don't like each other very much, do you?" he said. Tom was silent for a moment. Then he looked away. "We get along, I guess." "Maybe. But sometimes just gettin' along isn't enough. Especially when there's trouble. Give it a thought, when you've got a minute or two...." Later, the three of them went over the computer results together. Johnny and Greg fed the navigation data into the ship's drive mechanism, checking and rechecking speeds and inclination angles. Already the Dutchman's orbital speed was matching the speed of Roger Hunter's asteroid ... but the orbit had to be tracked so that they would arrive at the exact point in space to make contact. Tom was assigned to the viewscreen, and the long wait began. He spotted their destination point an hour before the computer had predicted contact ... at first a tiny pinpoint of reflected light in the scope, gradually resolving into two pinpoints, then three in a tiny cluster. Greg cut in the rear and lateral jets momentarily, stabilizing their contact course; the dots grew larger. Ten minutes later, Tom could see their goal clearly in the viewscreen ... the place where Roger Hunter had died. * * * * * It was neither large nor small for an asteroid, an irregular chunk of rock and metal, perhaps five miles in diameter, lighted only by the dull reddish glow from the dime-sized sun. Like many such jagged chunks of debris that sprinkled the Belt, this asteroid did not spin on any axis, but constantly presented the same face to the sun. Just off the bright side the orbit-ship floated, stable in its orbit next to the big rock, but so small in comparison that it looked like a tiny glittering toy balloon. And clamped on its rack on the orbit-ship's side, airlock to airlock, was the _Scavenger_, the little scout ship that Roger Hunter had brought out from Mars on his last journey. While Greg maneuvered the Dutchman into the empty landing rack below the _Scavenger_ on the hull of the orbit-ship, Johnny scanned the blackness around them through the viewscope, a frown wrinkling his forehead. "Do you see anybody?" Tom asked. "Not a sign ... but I'm really looking for other rocks. I can see three that aren't too far away, but none of them have claim marks. This one must have been the only one Roger was working." They stared at the ragged surface of the planetoid. Raw veins of metallic ore cut through it with streaks of color, but most of the sun-side showed only the dull gray of iron and granite. There was nothing unusual about the surface that Tom could see. "Could there be anything on the dark side?" "Could be," Johnny said. "We'll have to go over it foot by foot ... but first, we should go through the orbit-ship and the _Scavenger_. If the Patrol ship missed anything, we want to know it."
