Generally speaking, the cheap decks people start the game with aren't very interesting to pilot. They don't have enough removal, which is one of the primary ways players interact with their opponent's board. They definitely d

But why would a rational, self-interested person put up with great risk and expense to live in a small closed economy on Mars, when they could much more easily live in a small closed economy on earth? What's so great about Mars?

Nautilus-X was pretty serious. You really want a pretty large diameter so that you don't have a huge gravity gradient causing your astronauts discomfort. Tethers might be more practical than the classical doughnut designs for the near

Delta-v to EML1 from LEO is 3.77 km/sec. Assuming an Isp of 320 sec, you get a mass ratio of about 3.3, which works out to about 75 Falcon payloads, not counting any hardware you need to boost. If you use ion thrusters, the delta-V bec

It's like religion in that people like to anthropomorphize wildly. The Cosmological argument ("Define God to be the first cause") becomes "... and that's why God smote a fig tree." Here, "Huh, the universe

It's not entirely clear what, exactly, it would mean for this to be true. It's also not clear that defining what we mean by "Is the universe a simulation?" has any value if it is not testable.

Another way to view it is that human rovers must go fast, because humans are impatient. We could build a faster, battery powered robotic rover if we wanted, but why? If it's simply mileage you want, Curiosity's RTG means it can ju

The big advantage of Orion is that we're reasonably confident it would work, and could probably build one within the decade with a serious effort. Zubrin's NSW rocket, on the other hand, falls into the "hasn't yet been c

So? Nobody has been able to present any credible economic plan for Mars, either, which makes it more like Antarctica (or central Greenland, if you insist on somewhere you can legally move) than Norilsk.

I believe you're mistaken about the gravity. Position is as R e^(i v/r t), so |acceleration| is as R v^2/r^2 -- right? For a fixed station of floor radius r, acceleration is directly proportional to distance from the center,

What would they use it for? If you're going to Mars, your vessel has a reasonable crew habitat, so you don't need Tiangong I for that. Tiangong I is more payload than spaceship. Its tanks can only hold about 1000kg of propellant.
