How far can I progress in the storyline contracts with only 90-point-tier technology? (KSP1+BG)

I’m a new player. I enjoy setting artificial constraints in new games because I find it challenging/rewarding and because I find the narrower scope to be more enjoyable as I don’t have much free time.

Choice can be overwhelming. If I limit myself to the technology that can be unlocked with 90 science points or less, how far do you think one could reasonable progress in the storyline contracts?

I would really appreciate your input. It will help with my long-term planning. Thank you.

u shouldn't limit urself on anything unless its more fun and enjoyable, i personally don't find it fun to limit myself but you do you if u like it you like it

anyway u would probably make it a quarter through at maximum

You can probably land a Kerbal on every planet and moon, though getting back will be a lot harder. Moho will be particularly difficult to get to and Tylo will be difficult to land on if the best vacuum engine you have is the Terrier and with only solid rockets and the Skipper(?) to launch heavy payloads with.

Thank you! This is very helpful!

Moho and Tylo don't appear on the story line contracts so I'm impressed that, with enough skill, I may be able to do all the "missions" with lower tier tech. This will likely incentivize LKO refueling for missions but if the challenge stops being fun by that point, I'll just advance in the tech tree to unlock some new shiny toy.
