I just used the calc, it’s closer to 152 years. Which I assume means acceleration at 1g for about a year to reach .999c, and deceleration for the same time.

I just confirmed with dV= a*t, a year of 1g(9.8m/s/s) gets you just over the speed of light. I think it’s more complicated than that, If I remember right relativistic speeds require more and more energy to accelerate so you can’t ever “reach” light speed.

Took me 3 tries to finish it, and I basically had to be firm with myself to only play that and not get distracted by other games.

It’s very good, but it’s one of those games you need to play in a relatively focused way, like watching a movie.

I only did that once on an Apollo style mun mission when I realized I didn’t put any rcs on it after 2 hours of mission. Took a few quick loads so I had enough fuel left to get back.
