Pluto was visible in the forward viewplates. They could see lighter and darker patches on it, almost like the markings of continents and oceans, but there was no evidence of an atmosphere, nor had they expected any.
Readings showed that the average surface temperature was about 200° Fahrenheit below zero, even lower in many places. They searched the surface for signs of their foe.
They found what they wanted on the north polar depression, a basin in the oblate sphere of Pluto. There was no ringed station. There rose a vast pile of dark masonry—a mighty structure covering at least a square mile, a fortress building whose roofs bristled with an array of masts and reflectors. And hanging on patrol over this polar basin were two more of the dumbbell ships.
"We're in no position to come to grips with them," said Lockhart. "I'm going to take the Magellan into a low orbit around Pluto's equator. We'll be out of their sight, yet near enough to do some probing and exploring while we're making repairs."
This they proceeded to do, swinging the ship down to within a few hundred miles of the Plutonian surface, setting on a fixed orbit around the equator, exactly as the sputniks of years past had first circled the bulk of the Earth. Staying far enough up to maintain orbit, they were close enough to be below the planet's radiation belt.
Taking stock of the ship's condition showed that they dearly needed this delay. Repairs would not be completed for several days. Practically everyone had been bruised or shaken up; Oberfield had a fractured skull and was in serious condition; Ferrati had broken his leg and pelvis; Shea had a couple of cracked ribs. The men were given emergency medical treatment and confined to quarters.
The Magellan quietly circled Pluto once every hour and a half and the ship tried to resume its normal life. Russ studied the surface beneath them, Haines and Burl at his elbow. Then, after conferring, the three approached Lockhart.
"We want permission to make a landing," Russ said. "If we take the four-man rocket plane we can make the ground safely. We've got to reconnoiter before we can figure out how to put this master Sun-tap station out of business."
Lockhart agreed. "I was planning as much. Now that we're here, we can't delay just because we're injured. Go ahead."
The three got ready quickly. They donned their space suits, loaded the larger rocket plane with equipment, arms, and plenty of extra fuel. Just before they left, Lockhart gave them a word of caution. "Do not attempt to communicate with the Magellan by radio. If Pluto is the Sun-tappers' home world, you may find yourselves surrounded by enemies, and overheard. Don't reveal our existence or position. If you have to talk to us, do not expect a reply unless it's an absolute emergency."
