Sennech was dull gray in the telescopes, showing, as they neared, flecks of fire. They went in fast, using her gravity to help them curve into a forced orbit as they strained to decelerate. Thermocouples gave readings close to the boiling point of water; that, probably, was the temperature of the lower air.
Roboscouts went down first, then, as conditions were ascertained, manned ships. Tulan took the flagship down once. Her coolers labored and her searchlights were swallowed in murk within a few feet. Sounds carried through the hull; the howl of great winds and the thumps of explosions. Once a geyser of glowing lava spattered the ship.
Within hours the picture began to form. The surface was a boiling sea broken only by transient mountain peaks which tumbled down in quakes or were washed away by the incessant hot rain. It would have been hard to find a single trace of the civilization that had flourished scant hours before.
The slower job was learning, by countless readings and painful deduction, what was going on inside the planet. Tulan occupied himself with organizational tasks and clung to what dignity he could. After an eternity Kliu had time for him.
"She'll blow, all right," the scientist said, sinking tiredly into a seat. "Within half a year. Her year."
"Twenty thousand hours," Tulan said automatically. "How about the other planets?"
"Coar has one chance in a hundred, Teyr possibly one in ten."
Tulan had to keep talking. "The outer satellites. We can do a lot in that time."
Kliu shrugged. "A few thousand people, and who knows what will happen to them afterward? It's going to be a long time before the System's inhabitable again, if ever."
