This is basically how I imagined it in my head, except it was more of a "end over end" spin rather than a flat spin, but the ship design and everything else almost exactly matches my mental image, which I think speaks to Weir's descriptive capabilities

[@preferredimage]

Yeah I thought that too but the images in the amazon digital version of the book show the above. google 'project hail mary ship' for the image.

I've listened to the audiobook three times, but for some reason I can't imagine the engine light as anything other than the blue in my imagination, even though I know that IR light is obviously red

[@stevenhetzel6483]

It's technically not even red, but due to superheating components/gas/dust it can appear red at times. In a perfect, ideal world, the spin drives give off completely invisible thrust.

[@grantfomin6829]

I think the red dots is a good compromise, since you can rationalize it as all the little revolver triangles. If I was making the movie, i'd make astrophage engines red. Its how I imagined it when reading. @@stevenhetzel6483

Really hope they don't try to make the ship look cooler or more appealing to the audience. The point of its designed was due to Earth just cobbing together something as quick as possible.

[@orange_turtle3412]

I do hope they make it look more realistic though. Like an actual functional spacecraft rather than a featureless silhouette of one. But not with any added stuff. Still just 3 big thrusters attached to a cabin at the top.

[@voluptuousvince6522]

But it also wasn't incompetent

[@howwired5656]

@@orange_turtle3412 the thing with that and after rereading the book for a few times I have realised that the spaceship doesn’t look like the conventional spaceship because it didn’t have to escape the earths atmosphere was built in space by the ISS crew and that’s why they could make it as aerodynamic as it is but still it is a bit aerodynamic so that it can move through space particles like radiation.

[@JoeCastellon]

This is probably because English is not my native language, but when listening to the audiobook (which is stellar btw) I had imagined something radically different from this. I'm glad I found this animation. It will do wonders as I continue listening to the audiobook again.

Oh wow! This version really is way better! I still wonder how on earth you would keep something like this balanced. Especially now that I have finished the book, and experienced the extremes to which this setup was subjected. Oh well, it's fun seeing it anyway. Also, amazing skill in Blender!

[@stevenhetzel6483]

You spin the ship before separation, otherwise the tethers could tangle. This puts you through high Gs at first, but as the overall length of the vessel is increased conservation of angular momentum slows the spin, and you get your desired 1g gravity.

[@wilmersandstrom2826]

Love this design over the one where the engines are directly attached to the bottom of the fuel bays. Still not sure if I like the split into three separate blocks or plates with engines. The book seemed to describe the Hail Mary as having one engine made up of 1000 spin drives. I always imagined it as being one single plate or bell nozzle with 1000 spin drives rather than 3 separete plates like the Amazon illustration shows.

[@mariasirona1622]

1009

[@DavidSigbi]

It was described as having 3 with 1009 spin drives. Remember the problem dr grace and rocky had where astrophage were dying they had to jettison one

[@wilmersandstrom2826]

@@DavidSigbi They had to jettison one tank of astrophage, they had like 9 tanks (I don't remember the exact number. Did they specify 3 separate mountings for the engine, I don't remember anymore but seems odd since 1009 would decide equally between them. The reason I say having them all together in the center would make it easier to even the thrust between whenever one gave out. Edit. They had to jettison multiple tanks. Don't remember the exact number

[@DavidSigbi]

@@wilmersandstrom2826 There is actually an illustration of the ship in the front of the book (on page 9 for me).

[@tongshengwu171]

@@helmetongrass1893 it cant, due to the intermediate axis theorem a rotation about the x axis will be unstable and cause wacky effects. Like when you try flip a phone head over head it always flips a little sideways also

[@helmetongrass1893]

@@tongshengwu171 yes, it makes more sense to rotate the ship along the Y-axis although i have never tried to flip a phone, but if i imagine it, you are right, maybe its because the thinner part of the system staying in the plane of rotation feels more stable than the part with wider area for some reason,

The ship should be rotating over its Y axis given the use of attitude control thrusters using Astrophage. Rotating on the X axis would have too much potential of tearing the ship apart. Really awesome model though!

[@SgtInvictus]

Very nice but I'm confused, how long would the Hail Mary be at full cable extension, this animation seems to show the ship growing to about 700 feet long or so, this wouldn't make sense though because the Hail Mary was spinning while the Blip-A was closer than 700 feet from it, I need help explaining this.

[@contramuffin5814]

The Hail Mary is 40-50 meters long. Based on my rough estimation, the centrifuge in the video is 3 times the length of the ship, making it around 150m in diameter. I'm pretty sure that's accurate to the book. The Blip-A was 216m away from the Hail Mary

[@eenayeah]

That is a huge distance from the main body to the fuel tanks! Was it really like this? Just finished reading the book. I imagined it to be much closer to each other, like the illustration at the start of the book.

[@preferredimage]

Yup. they mention distances and times when things are where they say or doing things they mention so I've tried to be as faithful as I can, including the long spin up time.

[@harriehausenman8623]

A certain distance is needed for the forces, spin-angle and corriolis be within nice parameters.

[@stevenhetzel6483]

Yes, the length of the vessel effectively triples in centrifugal mode according to the given measurements.

[@schnatzikowsky4262]

I'm sorry but you got this wrong. The rotation should be along the vertical axis, not the horizontal one. Otherwise it would make no sense to turn the ship's nose inwards in the first place. The way you did it, gravity would pin the astronaut to the wall of the ship, not to the floor as on earth.

[@preferredimage]

Nope, centrifugal is centrifugal whichever way you spin it. I just did it the way the book shows you how its done.... static.wikia.nocookie.net/project-hail-mary-andy-weir/images/5/56/Hail_Mary_art._gravity.jpg

[@schnatzikowsky4262]

@@preferredimage My bad, the drawing in the book obiously supports your animation. But it somehow still feels counterintuitive to me. To achieve the desired gravitational effect, wouldn't the rotation have to be along the vertical axis of the ship? Because the way it is depicted, surely the main resulting force is directed against the wall of the reversed ship, and only a smaller part of it against the floor. Whereas a "vertical" rotation would produce gravity exclusively towards the floor, imitating Earth's gravity in a much more natural way. But maybe I'm just missing something here. Anyway, good job with the graphics!

[@Wurtoz9643]

@@schnatzikowsky4262the way the “centrifugal force” acts is straight away from the centre of rotation. You can test this yourself by putting a weight on a string and spinning it around. It goes away from you because you are the center of rotation.

[@Fgtuoae]

Is this real? question?

[@redrum666]

so what was the point of the ship doing this? i dont get the point

[@preferredimage]

Its to create an artificial gravity on the nose part of the ship by spinning it and the floor now being on the inside edge. You are being flung outward onto the floor, a bit like gravity.
