A few months ago I saw a video of a dude that was talking about the plans of THE COMPANY regarding exploration and colonization. I don't know how credible that dude is, who he actually is, what his sources are or in what relation he is to THE COMPANY, but he was explaining it, in much detail actually. I don't even know the video link anymore, but it is definitely out there somewhere (look between 2013 and 2016 on youtube).
Anyways, the way he described it, once a new planet if found from a jump point, it will start generating missions, first scouting,recon,prospecting, then transports of workers, terraforming equipment, later parts for factories, more workers & colonists, basic supplies like food and water, since they would not be self-sufficient to start. The numbers of missions would be massive, to the point that it would be difficult for any one group to colonize a planet alone. It would be a massive undertaking, for every single habitable planet found. So you need a big coordinated attempt with 200+ players to make it work. There might be other groups attempting to colonize too, so there will be political negotiations sometimes turning into peace, coalitions, war or even the destruction of the whole planet, impacting the colonization process and the economy of the galaxy (if you watch the news during a colonization conflict you might be able to make extra profits, by selling medical equipment or ammunition to that planet for example; or you will be able to use the chaos and dog-eat-dog-vibe that unfolds hours before a planet will get destroyed to enslave players or save them for inhumane amounts of cash [you can still enslave them when they are on board so you would make double profit]). You will actually need trained workers for the terraforming equipment that might be needed, it will be possible to alter the composition of the atmosphere and soil if you know how to do it (so this is another potential career for players, terraforming engineers). They are also plan on making players able to create planets, so the gameworld will be expandable, although this will very likely be quite a resource-hungry process.
