smile. “It’ll be the same ice as here. You just want to go.”
“Well?” Ann said. “Say I do! There are still scientific questions to be answered up there. Is the ice the same composition, how much dust—everywhere we go up here we collect valuable data.”
“But we’re up here to get water. We’re not up here to fool around.”
“It’s not fooling around!” Ann snapped. “We obtain water to allow us to explore, we don’t explore just to obtain water! You’ve got it backwards! I can’t believe how many people in this colony do that!”
Nadia said, “Let’s see what they say at base. They might want us to help with something there, or they might not be able to send a drop, you never know.”
Ann groaned. “We’ll end up asking permission from the U.N., I swear.”
She was right. Frank and Maya didn’t like the idea, John was interested but noncommittal. Arkady supported it when he heard of it, and declared he would send a supply drop from Phobos if necessary, which given its orbit was impractical at best. But at that point Maya called Mission Control in Houston and Baikonur, and the argument rippled outward. Hastings opposed the plan, but Baikonur, and a lot of the scientific community, liked it.
Finally Ann got on the phone, her voice very curt and arrogant, though she looked scared. “I’m the geological head here, and I say it needs to be done. There won’t be any better opportunity to get onsite data on the original condition of the polar cap. It’s a delicate system, and any change in the atmosphere is going to impact it heavily. And you’ve got plans to do that, right? Sax, are you still working on those windmill heaters?”
Sax had not been part of the discussion, and he had to be called to the phone. “Sure,” he said when the question was repeated. He and Hiroko had come up with the idea of manufacturing small windmills, to be dropped from dirigibles all over the planet. The constant westerlies would spin the windmills, and the spin would be converted to heat in coils in the base of the mills, and this heat would simply be released into the atmosphere. Sax had already designed a robotic factory to manufacture the windmills; he hoped to make them by the thousands. Vlad pointed out that the heat gained would come at the price of winds slowed down—you couldn’t get something for nothing. Sax immediately argued that that would be a side benefit, given the severity of the global dust storms the wind sometimes caused. “A little heat for a little wind is a great trade-off.”
“So, a million windmills,” Ann said now. “And that’s just the start. You talked about spreading black dust on the polar caps, didn’t you, Sax?”
“It would thicken the atmosphere faster than practically any other action we could take.”
“So if you get your way,” Ann said, “the caps are doomed. They’ll evaporate and then we’re going to say, ‘I wonder what they were like?’ And we won’t know.”
“Do you have enough supplies, enough time?” John asked.
“We’ll drop you supplies,” Arkady said again.
“There’s four more months of summer,” Ann said.
“You just want to go to the pole!” Frank said, echoing Phyllis.
“So?” Ann replied. “You may have come here to play office politics, but I plan to see a bit of this place.”
Nadia grimaced. That ended that line of conversation, and Frank would be angry. Which was never a good idea. Ann, Ann….
The next day the Terran offices weighed in with the opinion that the polar cap ought to be sampled in its aboriginal condition. No objections from base, though Frank did not get back on the line. Simon and Nadia cheered: “North to the Pole!”
Phyllis just shook her head. “I don’t see the point. George and Edvard and I will stay down here as a back-up, and make sure the ice miner is working right.”
So Ann and Nadia and Simon took Rover Three and drove back down Chasma Borealis and around to the west, where one of the glaciers curling away from the cap thinned to a perfect rampway. The mesh of the rover’s big wheels caught like a snowmobile’s drivetrain, running well over all the various surfaces of the cap, over patches of exposed granular dust, low hills of hard ice, fields of blinding white CO2 frost, and the usual lace of sublimed water ice. Shallow valleys swirled outward in a clockwise pattern from the pole; some of these were very broad. Crossing
