Not really a fan of Frontier space - too big of a rule book to digest- I just default to Star frontiers. 

however, I think if you produce a full module you could ask Bill Logan, the owner of Frontier Space to buy if from you for a set fee or you can ask him for a royalty on the module or you could just ask for a license and sell it on Drive thru yourself. Or you can give it away for free as a STar Frontiersman Presents module. Lots of options there- I'll do what I can to assist. 

I will probably need help, as I don't write modules, I put together rough outlines, notes, lists of NPCs to use as needed, rough maps, free flow adventures and tend to fly by my pants a lot... but then I am usually really familiar with the setting and have ideas prethought to deal with PCs going off this way or that... almost like choose your own adventure. However anyone trying to decipher how I do this would not have a chance... and I want to do a formal module as a challenge to myself but also so other people can use it. 

So I am starting with planet... I already know some aspects I want... Antarctic cold is the nice part of the world. It has seasons, an ocean, some ocean based lifeforms and some glacier life. There are other properties I ha e to decide on still... but basically a hostile environment but survivable with proper equipment. 

Bases will include old abandoned sites, year long sites and summer only sites. Bases will reflect races, companies and governments present. Planetary travel is best certain seasons.... with landing pad areas and runways being accessible during specific time periods... climate effects everything including supply star ship delivery.

I need to nail down the Villian/s motivations... 

Definitely a murder mystery, with NPCs getting eliminated and attempts made on PCs.

Nearest next base will be a rival, so suspect, but if PCs go there they will find everyone dead, equipment destroyed... so they will really have to go far for help.

Other active bases people will be alive at.

Communications will have to be destroyed at home base. 

I will hand draw maps.

I need to find a writing program for my iPad as my computer died.

So first will be using good old fashion pencils and paper... but goal is a nice formal polished module, complete with pregenerated PCs for people to use. 

I know I will need help... ???? ... I can do this I just have to put my "time to write college paper hat" on.

I did this in a system ship liner trip from Pale to New Pale and the player who was "if we are not killing everything in the room then I'm bored" kind of checked out mid adventure- talking to NPCs is so hard for some people. At any rate I dont think I delivered well on that game as they just didn't get it.

My advice: model your module on one you really like. A well written Table of Contents is crucial especially for someone like me that will use it to jump to the parts I want to read first like I might skip the setting details to sink my teeth into what the story here then go back and read the setting detials once I "buy into" the adventure. Although you can never really finish the ToC till you finish the document anyhow. 

There might be something to be said for the DM advice "only create what you need" I've been looking at some fo the SF modules and I think that was the approach of the TSR writers.

For myself when it comes to setting I like the "whole earth ecology approach" environments- at least three, host of creatures and I want to actually create a wandering encounter table for DMs that will use it. I like character portraits to go with NPC descriptions but that is not always needed (and if I blow the dust off my drawing skills I'm not a half bad portrait artist) 

and I think the advice on eating an elephant also applies- how you get this done is one bite at a time. 

finally if you are going to go to the trouble of creating a whole setting you should write up at least 3 adventures. whether its three full modules or WoWL style with short quick encounters. that can be strung together into a mini campaign or interspersed in a larger campaign. My initial thoughts.
