Victorian Spaceflight

Ancillary Justice by Anne Leckie

I've been trying to spend more time reading science fiction and less time surfing the net. It's not working great, but I am making some progress. I read Ancillary Justice by Anne Leckie last month and it's pretty great. Galaxy spanning adventure with a roboticized human who is ostensibly under the absolute control of his/her masters. The sex of any of the characters is never made clear, but it doesn't really matter. Anyway, about halfway through the story you realize he/she is lying. Ack! Now the story becomes very interesting. I think I read this once once before, like a zillion years ago. The part that stuck in my mind is a group of evil masters destroys a large military starship filled with thousands of troops AND THEMSELVES to keep some vital information from getting out. Fortunately for us, and unfortunately for them, our hero manages to escape before the ship explodes. Think that might have impacted her ability to be truthful?

Hillsboro Library Friends Shop

On a recent visit to downtown Hillsboro, I stopped by the Hillsboro Library Friends Shop, a tiny little bookstore next to the Max commuter rail line. They seem to be stocked with surplus from the library, books that are no longer in fashion, maybe. Anyway, I picked up a couple of science fiction novels for cheap, like a couple of bucks each, less than the price of a candy bar. 

One of them is The City Who Fought by Anne McCaffrey and S. M. Sterling. It's not great, but it's not too terrible, so I'm plugging along. 

Anyway about a third of the way through, this giant spaceship comes hurtling out of depths, headed right for giant space station. Through masterful machinations, our heroes manage to avoid a collision. Bah, humbug. Makes for great drama, but statistically speaking it is nonsense.

Any star fairing civilization, as a matter of course, is going to maintain a scan of their entire sphere of view for possible interlopers. Shoot, we are barely getting off the ground and we are doing that now. That's how we detected the recent interstellar asteroid that came through our system.

If a starship was approaching Earth, decelerating at one gravity, and we just detected it by the time it crossed Pluto's orbit, it would still take 9 (nine) days to get here, which should give us plenty of time to move our space station out of the way. Even if it were decelerating at ten gravities, it would still take three days to get here.

Deceleration

Average Radius of Pluto's orbit	40	Astronomical Units
times	93,000,000	Mles per Astronomical Unit
equals	3,720,000,000	Mles
times	5,280	Feet per Mile
equals	19,641,600,000,000	Feet
Formula	Distance = (1/2) times Acceleration times time squared
Formula solved for time	Time = Square root of (Distance divided by Acceleration)
Acceleration	32	feet per second per second
Time	783,454	Seconds
divided by	86,400	Seconds per Day
equals	9	Days
Formula	Velocity = Acceleration times Time
Velocity	25,070,525	Feet per Second
divided by	5,280	Feet per Mile
equals	4,748	Miles per Second
equals	2.6	% Speed of Light

I want to see more science fiction stories about space flight WITHOUT warp drives. Stories about voyages that take months or years. Kind of like Patrick O'Brian's stories about commander Jack Aubrey.
