Description
V2 Change log:
Appearance adjustment of the primary mirror, so that it looks more "segmented" instead of like a whole. This is done by using a better panel attachment method.

V1.1 Change log:
Added missing membranes between primary mirror and Instrument Module (see the two screenshots in SPH).

------------------------------------------------------
This is my take on the legendary JWST.

Stock + Making History DLC, 469 parts.
Root part is a small battery bank in the center of primary mirror. It's decided for ease of building but is tricky to find. Press 4 and reroot to any other part you like.

Design Notes
- The parabolic mirror surface took me quite a while to build, glad I finally made it. It has a diameter of ~5.5m, the real size is 6.5m.
- It has ~360m/s of vacuum dV with a TWR of ~0.12 in Kerbin SOI.
- There is a Sentinel telescope behind the primary mirror plus some science instruments, so it's not useless in game.
- But it's not practical due to weight and cost. IRL the sun shield is made of super thin membranes, but on this craft there is a huge amount of solid structure panels.
- I'm aware that JWST has 5 layers of sun shield membrane instead of 4 on this craft, but giving it another layer would break the part count of 500, and it just looks not very different. So I made this compromise. If you want, just hold Alt and click on the plate indicated in the last screenshot, it's easy to copy and paste this layer.

Action Groups
AG1=horizontal control point
AG2=vertical control point (default, in line with engine thrust)
AG8=conduct experiments
AG0=engine on/off

Launch
Alt+F12 to set orbit.
I thought about making it to be able to fold/unfold but gave up due to the complexity, so it can't be launched like IRL.
I'll try to build a large lifter for it, but no promise on that...

Wish you enjoy and happy launching on schedule!

Weird...Just to be clear, its in-game name doesn't have the tag [MH] and as such begins with J, perhaps this causes some misunderstanding? If so I'd change my DLC tags from prefix to suffix

For some reason, it isn't appearing on my Load Spacecraft menu, that is a little weird, mind telling me if i need a certain version for it to work?
