It is an add-on I'll look it up and get back to you because I don't remember which one right nowHey PROrbiter, just curious, what are your atmospheric config settings? Looks nice! Is it from the atmospheric enhancement add-on or something customized?
I'm doing one which will have all the SM3B exterior hardware added to it(NICOMS Cooling System and Solar Array-3).Niiice
Are you also making an HST, and will it be possible to berth the FSS to the HST?
This will be an awesome mission !!
