This is good news. The extra time should help deliver a better game, when all's said and done.
I've struggled to give timely feedback on the rules in the face of the summer "deadline," and I was afraid that'd hurt Pioneer. Luckily, Pioneer's getting extra time to bake. I'll see if I can deliver that feedback this month.
In case I miss my deadline: hopefully the core rulebook (or a hypothetical Referee's Guide) will offer more support for sandbox campaigning (non-EVA activities, space agency/company economics, quick mission generation).
