Vessel Hermes Spacecraft from The Martian

[wllmpeek]

So, when is one of our brilliant developers going to make a kick ass replica of the Hermes Spacecraft from the movie The Martian? Is someone currently working on it? If so, who?

Looks to me like you can build something close now with Interplanetary Modular Spacecraft. (IMS)

What is the propulsion system?

 

[ccapeahrt1017]

im pretty sure there still using chemical propulsion

First off, probably should move this to Addon Requests.

That said, I have to agree that the first thing I thought of when I saw the Hermes was that I couldn't wait to fly this mission in Orbiter!

We've been somewhat blessed in the last few years with Sci-Fi movies featuring reasonably realistic ships. Gattispilot is doing a great job of modeling the vessels from Interstellar, and I'm really looking forward to whoever decides to tackle The Martian.

It won't be as easy a job as it first looks either. For the full mission the MAVs will also need to be modeled, and as far as I know we were never shown what the descent stage looked like before it was decoupled from the Hermes (presumably the hab module was the descent stage reconfigured on the ground -- I've only seen the movie once so forgive me if I missed something here like a separate clearly labeled descent stage sitting off to one side).

Because of the constant acceleration trajectory, I thought the engine was an Ion one.

Andy Weir is such a geek I'm sure if someone emailed him saying they wanted to make the Hermes for Orbiter, he'd provide us with all the little details of the whole mission :lol:

The Atomic Rockets website has a chapter on Hermes concepts, with reverse-engineered data from the book and the movie.

The engine is mentioned to be an ion engine in the book.

 

[MaverickSawyer]

It was argon fueled, iirc, so it could be a gridded ion engine, a Hall effect thruster, or even a VASIMR unit. Each of them would need the power of a small nuclear reactor to achieve the required thrust to accelerate the mass of the Hermes in a reasonable manner.

 

[Andy44]

I just finished the book. They use the term "ion engine" several times, and in one piece of dialogue the word "vasimr" is used. The ship has a "reactor room" which is a pressurized space. Few other details are mentioned, other than that the main drive is low thrust and high Isp.

I agree that inviting the author to join OF might not be a bad idea. He sounds like the kind of guy who might be willing to do it, and he's the one with all the tech research on the story.

I would love for this to happen. The cockpit also looks very cool

 

[barrygolden]

All of the stuff from the movie needs to be made

 

[N_Molson]

I'd say gather as much reference material as you can find and post it here. Having a bunch of material to get inspiration from, or even better, blueprints, makes the modeling process much more appealing.

 

[barrygolden]

I will see what I can find I loved the movie and the ERV , truck, the hab but really liked the spacesuits

When I read the book I was totally thrilled on the realism that Andy Weir packed into the story, and still wrote an absolute page-turner book!
With the formulas on the Atomic Rockets page, I tried to draft a concept of the 'Hermes' as a nuclear-powered, ion-driven vessel.

I collected the tidbits of information from the book on maneuvers and flight duration, summarized them in a spreadsheet.
I have to say this was long before the movie. My concept was by far less cinematic.
I ended up with a 60 ton dry mass vessel, consisting of an 85 m long truss, an inflatable trans-hab on one end, and a reactor on the other,
spinning head-over-heels for artificial gravity.
The reactor had a thermal power of 10 MW, with an electrical yield of 8 MW.
Using two arrays of ion engines allowed flight times of 124 days single route, as described in the book.

Calculation data and a short description is included in the attached file 'Hermes.zip.'
The design may be outdated nowadays, but maybe the figures can help to make a proper Orbiter vessel.

Not Orbiter but here is my take on the Hermes.

Then what is it? Space Engine?

Render I made in UE5 modeled in blender

 

[misha.physics]

Didn't you think to export it into Orbiter? Or is this a non-free model?

 

[Spaceman 3D]

Do you have a Supercomputer? Modeled everything myself. It's made for Renders whith high poly count. Would have to remodel it.
