Professor Hartzenbosch bridled at that. The great author ought to be coming to his school out of respect for him, not because a seventeen-year-old cub reporter sent him. But then, Professor Hartzenbosch always took the attitude that he was conferring a favor on the _Times_ when he had anything he wanted publicity on. The elevator door opened, and Lautier and the professor joined in the push to get into it. I hung back, deciding to wait for the next one so that I could get in first and get back to the rear, where my hamper wouldn't be in people's way. After a while, it came back empty and I got on, and when the crowd pushed off on the top level, I put my hamper back on contragravity and towed it out into the outdoor air, which by this time had gotten almost as cool as a bake-oven. I looked up at the sky, where everybody else was looking. The _Peenemünde_ wasn't visible; it was still a few thousand miles off-planet. Big ragged clouds were still blowing in from the west, very high, and the sunset was even brighter and redder than when I had seen it last, ten hours before. It was now about 1630. Now, before anybody starts asking just who's crazy, let me point out that this is not on Terra, nor on Baldur nor Thor nor Odin nor Freya, nor any other rational planet. This is Fenris, and on Fenris the sunsets, like many other things, are somewhat peculiar. Fenris is the second planet of a G_{4} star, six hundred and fifty light-years to the Galactic southwest of the Sol System. Everything else equal, it should have been pretty much Terra type; closer to a cooler primary and getting about the same amount of radiation. At least, that's what the book says. I was born on Fenris, and have never been off it in the seventeen years since. Everything else, however, is not equal. The Fenris year is a trifle shorter than the Terran year we use for Atomic Era dating, eight thousand and a few odd Galactic Standard hours. In that time, Fenris makes almost exactly four axial rotations. This means that on one side the sun is continuously in the sky for a thousand hours, pouring down unceasing heat, while the other side is in shadow. You sleep eight hours, and when you get up and go outside--in an insulated vehicle, or an extreme-environment suit--you find that the shadows have moved only an inch or so, and it's that much hotter. Finally, the sun crawls down to the horizon and hangs there for a few days--periods of twenty-four G.S. hours--and then slides slowly out of sight. Then, for about a hundred hours, there is a beautiful unfading sunset, and it's really pleasant outdoors. Then it gets darker and colder until, just before sunrise, it gets almost cold enough to freeze CO_{2}. Then the sun comes up, and we begin all over again.
