question:  What is the landscape of Ganymede like?
context: Its reddish tinge brightened the office noticeably, for such of Ganymede's surface as could be seen through the transparent dome outside the office window was cold, dim and rugged. The glowing semi-disk of Jupiter was more than half a million miles distant. "A little percentage here and there on the cargoes never shows by the time figures get back to Earth. Maybe they live soft back on Earth since the mines and the Jovian satellite colonies grew; but they were out here in the beginning, most of them. "You know I took this piloting job just to scrape up money for an advanced engineering degree back on Earth. It had been built for Ganymede, but not for Jeffers. Tolliver began to have his doubts the next day; which was "Tuesday" by the arbitrary calender constructed to match Ganymede's week-long journey around Jupiter. He soon found that there was nothing for him to do but hang around the garage in case a spaceship should land. Sometimes there's no reason but them for sending a ship back with a crew instead of in an economy orbit. They found they could send back loaded ships by 'automatic' flight—that is, a long, slow, economical orbit and automatic signalling equipment. Then they're boarded approaching Earth's orbit and landed by pilots who don't have to waste their time making the entire trip." Then he headed the tractor across the frozen surface of Ganymede toward the permanent domes of the city. "Any square inch of Ganymede is likely to be dangerous." "Ganymede's only about the size of Mercury, something like 3200 miles in diameter, so things get heaped up at steep angles. When the rock and ice are set to sliding, they come at you practically horizontally. "I'm retiring in six months if I'm still alive," he said bravely, edging the tractor into the airlock at their destination.
