Right: Artist Duane Hilton's concept of Santa and his reindeer as they deliver Christmas presents to future space colonies.
In an exclusive interview, Science@NASA visited Santa Claus at his secret North Pole workshop. He took a break from final preparations to talk about how he'll maintain his legendary delivery system as humankind inhabits other worlds.
One of the senior elves was asking about overtime to complete a special batch of toys.
"I worry about the elves," Santa continued. "They count on a slack period to fix the factory and invent new toys for next year. I'll have to hire more helpers if we're going to service the Moon and Mars, too."
What about the other planets?
"You'd think that Mercury would be the hottest planet, but Venus is actually a little warmer because of the greenhouse effect in its carbon dioxide atmosphere. That's not to say Mercury isn't hot -- it's scorching! Daytime temperatures reach 500 degrees C. The appealing thing about Mercury, at least for the kids, is that the planet's year is just 88 Earth days long. Imagine that! Christmas every 88 days. It's a bit too often if you ask me, but that's gravity for you."
Santa paused for a moment.
"Jupiter doesn't have a solid surface, so any future colonies will probably be suspended in the clouds. Jupiter's atmosphere is made of hydrogen, helium, methane, and ammonia. It's pretty toxic but not nearly as bad as Venus's atmosphere. We'll need special protective suits for both planets, which is bad news because the reindeer hate wearing anything besides bells."
"Jupiter is so far away I think I'll turn Europa, the third largest moon, into a branch office. It's entirely covered with ice, just like the North Pole here on Earth, so the elves would feel right at home."
"Of course we'll probably steer clear of Europa's neighbor Io," continued Santa. "Did you catch the latest Galileo images? Superheated lava pools, volcanoes erupting all over. It's not exactly the North Pole, if you know what I mean. Actually there is some snow on Io but it's all made of smelly sulfur compounds."
Santa paused again to initial some requisitions for spare parts for the sled.
"Uranus and Neptune are just the same. Pretty planets, nice gas giants, but very far away. Uranus has some pretty nasty storms, by the way -- have you seen those Space Telescope pictures?" he asked. "Mrs Claus says they're even better than the Weather Channel!"
"Now just suppose I was way out there at Uranus delivering toys, and I was ready to fly home. Uranus is 19 times farther from the sun than our planet. Do you realize it'll take almost 7 hours for me to radio a message back home? I always send Mrs. Claus a message to start warming up the hot cocoa, just before I head back to the North Pole. Why, I'll be home before the message arrives!" he exclaimed.
Did that mean that Santa can travel faster than light? Wouldn't that violate the laws of physics? Before we could pursue this amazing revelation, the Jolly Old Elf's face brightened, and he went on:
"Pluto's got real possibilities," he warmed to his theme. "I say we've got to hurry up with planetary exploration. Mars tomorrow, then Jupiter and onward to Pluto! Once we get to Pluto, I might just set up shop there and the human race can keep my calendar. Christmas once every 247 years. That might make things a bit easier - I'm not as young as I once was...." Santa looked thoughtful.

Just then Mrs. Claus quietly appeared from the kitchen and thrust a bag of cookies into our hands.
"You really must go, dears," she said. "He has a long night ahead of him, after all." We went to the front door and bade our farewells. The stars shone brightly in the clear Arctic sky. As we turned to our dog sleds to begin our journey home, we heard Santa's voice boom from within: "Merry Christmas to all, and to all a good night!"
