as a boardgame you can have a look at Leaving Earth or to something more complex like High Frontier 4 All.
Computer I played MArs Horizon, but I wasn't a big fun, mostly because at the end I discover that I enjoy the planning but i also enjoy the handling of the ship
I've played around 5h, not much, but as I recall it was exactly what you think if you want to design a space race game, you do something basic, get new technology and then try something more advanced. As you go progressing you can do more stuff and get farther away, but it was not fun. I only recall the feeling of "this are the type of mechanisms that sounds like fun but when you are doing it, it was not".
There is a demo, you should try it.
