Question Farming in Space: SHEEP
I have got a big rotating space station (radius is 5 km and length is 30 km) which provides its occupants the luxury of full terran gravity and atmosphere. The biggest part of the cylinder's inner surface is covered by forest (which provides us with oxygen), small lakes, fields and farmland. Now, I h...

The universe does not have FTL travel, and the nearest hospital where Bob can be treated is 5 years of space voyage away. If he is not treated within one week, he dies. I need a way to preserve Bob.

Question What is the most effective way to brake from interstellar speeds?
In my story, I have a slower-than-light starship (traveling at 0.6 $c$) going to Alpha Centauri A. There are several planets around the star. The target planet is a terrestrial, habitable world orbiting at 1.2 AU (since Alpha Centauri is slightly bigger than the Sun) and a gas giant 3 times the size ...
