I'm looking at the National Wonders to clear up the icon issues, and I do not think we need to have both the
Deep Space Research Institute and the
Space Laboratory.
They are so close together and so few differences between the two that I don't think we need both.
Stats comparison:
Deep Space RI Space Lab
Required Tech Space Flight Space Stations
Required Project Hubble ISS
Cost 560 980
Science 10% 30%
Specialist Slots 1 Scientist 2 Scientist
Great PP +1 Scientist +1 Scientist
Spaceship 20% 20% Global
Other things I don't like are having a global space production bonus on a National Wonder and, in general, having space production bonuses on anything in the Modern Era. I don't think it's much of a choice if you can have all your bonuses in place before you even start building your spaceship. In original BTS, the Laboratory is not available until Superconductors, so you have a choice between pursuing Superconductors and getting Laboratories in place, or get the other techs first which lets you start building some parts without Labs.
I think we should consolidate with the DSRI being at Space Stations. It can keep the +30% science bonus and 2 Scientist slots, but I think it should have just 20% Spaceship production and not 20% global space production. Hubble can get a small global Science bonus (I think +10% is fair) instead.

I also looked into the possibility of combining the
Rubber Factory and
Rubber Plant. I can't see a way to do this legitimately without a lot of work.
Rubber Factory requires
Refining and makes Vulcanized Rubber out of Rubber and Lead. Rubber Plant requires
Plastics and makes Vulcanized Rubber out of Chemicals. It is not possible to do Resource X or (Resource Y with Tech Z).
Both Refining and Plastics are on the low end of trick counts. Refining has 2 other tricks (Well, Oil Refinery) and Plastics has 2.5 (Hydro Plant, Offshore Platform, Napalm Bombs promo). I don't want to reduce a tech into that range if it's avoidable.
Furthermore, consolidating the two at Plastics makes Plastics an additional prerequisite for
Motorcycle and
Armored Car. (Most of the other things that require Vulcanized Rubber are later on the tech tree and won't notice any changes.) This is okay for Armored Car but really hurts Motorcycle. I'd like Motorcycle to have a reasonable lifespan until
Jeep shows up. Automobile is on the prereq chain to Plastics and so Motorcycle wouldn't show up until then.
Consolidating at Refining is possible, but I don't like it very much. The Chemicals resource is available before Refining, so it becomes much less of a limitation. Moving up Organic Chemistry would fix that, but it means rewriting somewhere between half and two-thirds of the Industrial Era, which I don't want to tackle at this time.
