Project Mirai (Hatsunese Space Station)

[Pipcard]

Now that I was done with my course project, I thought I would be able to start the modeling for spring break (starting this weekend and lasting for about a week). Unfortunately, I might not be able to have access to my PC, so all I'll have is my tablet.

Why? Because only freshman dorms are closed during spring break, and only the freshman dorms. I don't know why.

edit: good news, a resident assistant was able to help me move my desktop PC to a different dorm for the week.

The font is called ITC Legacy Sans LT Bold. It is the same font used for the Hatsune Miku logo.

I have to do the Starlab insigna... :hmm:

Core module (with docking/berthing petals, grapple fixtures, and handrails):

The plan is currently to support six crewmembers like the ISS, but is it reasonable for it to support ten (so that I could use all the seats of the two RCVs that are always going to be docked)?

Especially when most of its modules are about the size of Kibo (Pressurized Module)?

 

[ISProgram]

The extra seats could be removed to hold pressurized cargo, like the crewed CST-100 will.

Something I just realized; how will Mirai perform propulsive maneuvers? It has no Zvezda-analog module on it, at least from what the current renders show...

Or will the space tug you're working on do this?

I know that (I even put that in the RCV description, that it could hold three people with some light cargo), but now I feel like those windows are being wasted.

Not sure about that. If you're talking about counteracting long-term orbital decay (which is not simulated in Orbiter), then the UTV (Unmanned Transfer Vehicle, HASDA's version of the HTV - I don't want to call it MTV) would do that.

If you're talking about attitude control, most of it will probably be from [ame="http://www.orbithangar.com/searchid.php?ID=5351"]CMGs[/ame] inside the truss. Yes, I have noticed that their momentum needs to be "desaturated" with actual "reaction thrusters," but the add-on does not simulate that. There might be thrusters built into the truss segments.

If your extra seats are for short term expeditions (<2 weeks), then I don't think your station will have any problems. IIRC the ISS is able to support 12 people for up to 1 month.

 

[Pipcard]

Well, I am talking about 3-month-long expeditions, with a RCV crew rotation in-between each expedition.

I don't understand what the in-between part is. It doesn't sound like the system used on the ISS, where half the crew starts the expedition in space and is joined a few weeks after by the rest of the expedition after they get launched up. Does the whole crew swap out in a short period of time, or is it more incremental, like the ISS?

 

[Pipcard]

Sorry for not making it clear, but it is supposed to be "incremental, like the ISS."

Considering that Kibo can have four crewmembers in it, and this station has six modules about the size of Kibo...

edit: or maybe it will have a permanent crew of six, and an extra five (including tourists/spaceflight participants) can be transported on an extra RCV to stay at Mirai for a couple of weeks, although I might need to have a couple more vehicles in the RCV fleet in order to do that.

That is not entirely accurate. The very thread you linked to in that post explains how Orbiter simulates orbital decay.

On what timescale are you talking about? Over the course of one orbit, it is usual to see apogee and perigee "increasing" and "decreasing"- this is an effect of non-spherical gravity. Actually, it is the reading on Orbit MFD that increases and decreases because it calculates your ideal orbit at every instant- your actual orbit will be fairly stable, but not quite what Orbit MFD predicts.

Atmospheric drag is calculated to an altitude of about 2000 km. However, as mentioned, it is disabled at high time acceleration-for good reason. Never forget that Orbiter is a numerical simulation and susceptible to "non-physical" results if the time-step is too high. In other words, you don't want to mess with it.

If you want to see atmospheric drag in action, put the simulation on about 1000x acceleration and wait about 2 real-world hours.

 

[Pipcard]

But at an ISS altitude, there seems to be no drag simulated; that's what I'm referring to.

Recently, I added RCS blocks (for rotation and forward translation) and made some other changes, and started texturing:

 

[Pipcard]

Hexagons are the future!

 

[ISProgram]

My gosh, how do you make those textures?! :blink:

 

[Pipcard]

So far, I made them from scratch using GIMP and Inkscape. For example, the gradient/blend tool (either in GIMP or Inkscape) is used for the metal, with some contrast added in GIMP, and the hexagon/honeycomb pattern is made in Inkscape. Not every texture will be made from scratch, though.

Berthing port texture. Original sources: [ame="http://www.orbithangar.com/searchid.php?ID=2804"]01[/ame], 02 (larger), 03.

A lot of editing had to be done in GIMP with contrast and most importantly, the perspective tool.

If anyone wants to, feel free to use it.
