![]() ![]() Crew Quarters are NOT bunched into a single continuous stack of decks, where the whole off-shift crew would need to try to crowd through the same narrow avenues in case of a sudden call to stations. Command Decks (Bridge, CIC, etc) of large ships are NOT placed at the bow of the ship, where even a single stray PDC round from an enemy ahead could knock it out, and where negative g-forces make all operations at crew stations impossible every time the ship changes heading (on small ships these effects are more marginal) In TRULY realistic warship designs at this particular point in the Expanse timeline: Unfortunately, this is not quite as true as one might have hoped. We wanted to make sure that they were as realistic as possible." "There are 28 ships detailed in this book, and we took a lot of time and care to get every one right. Just in case you want to challenge my numbers, I put all the calculations in this python code.In an update on, co-author Ian Lemke expounds upon the complexities of writing a book like this: Yes, it’s a rough estimate-but it’s still better than nothing. Then I can use the length and width to calculate the volume and density.įinally, by using the Space Shuttle density, I can determine the mass of the Razorback. ![]() What about the Space Shuttle Discovery? This has a mass of 110,000 kg. But I could use a REAL spaceship as an example. Oh, you don’t know the density of a spaceship? Well, neither do I. Yes, I can use this volume to estimate the mass. This would put the total volume of the Razorback at 217 m 3. The volume of this would be the area of the base (5.7 times 5.7) multiplied by one third of the height. Now let’s pretend like it’s a pyramid with a square base (it’s not). ![]() I can also measure the width at the rocket end at about 5.7 meters. Using this as a scale, the entire length of the ship would be around 20 meters. Since they show a doorway, I can assume that it’s about 2 meters tall (seems reasonable for a door). I can actually get a better estimate of the size of the Razorback. The Belter ship is wider and bulkier and made for normal space travel. Although the Belter ship and the Razorback are fairly close in length ( probably between 20-30 meters), they likely have very different masses. Is it possible to estimate the mass of the two spacecraft? Maybe. I’m not going to tell you if it works-you will just have to watch the show. Bobbie (in her powered Martian armor) grabs ahold of the gangplank and the Razorback to keep the ships together. However, Alex isn’t back on the Razorback yet. Once the Belter ship realizes that it can’t gain control of the Razorback, it decides to take off. It’s like a legit pirate battle on the seas (but no ropes swinging back and forth). Bobbie takes care of the boarding party while Alex jumps over to mess with the Belter ship. Bobbie and Alex are in the Razorback-a smaller and super fast (high acceleration) ship. I’m not going to spoil the whole episode, so let me just give you the important details. Let’s look at a scene in Season 5 Episode 6: Tribes. Sure, it’s not perfect-but each episode contains a lot of really cool science. Is there a better sci-fi show than The Expanse? It’s possible, but I think this one has a great balance between story telling and accurate physics.
