The Martian orbit is quite elliptical relative to Earth. Sunlight during the perihelion months is 40% brighter than at aphelion. Not from the angle of Sun, like we worry about with Earth seasons, but the actual size of the Sun in the sky. F

A time system useful on Mars needs additional consideration; considerations we haven't given it yet. It requires more thinking than just time zones. The various things we've sent to Mars haven't had any need for a colloquiall

Hard to say. In some places it's clear: LLVM's error messages were head and shoulders better than GCC's, and it was immediately obvious to everyone that GCC had to improve. And they're much better now. But I don't b

Yup, I get it. The energy released by a thermobaric weapon is spread out over a very, very large distance. Inside the blast, people will be killed and equipment will be rendered interoperable by the extreme temperature and the over pressure

Won't work. Thermobaric weapons are very good at killing people, and breaking equipment, but aren't particularly good at evacuating material.

I think you've overestimating how much stuff an explosion removes, as opposed to breaks. Explosions are very good at making a functional thing not function anymore, but they're not as good as you think they are at evacuating an ar

Starlink's effect on astrophotography is overstated. Starlink is in a fairly low orbit, so past twilight, the satellites are in Earth's shadow and aren't visible. The Iridium constellation orbits at 780km, for instance, while

One way to do a ratio of 720:1151 is to construct a gear with 720 teeth, and a second gear with 1151 teeth, and mesh them together. This wouldn't be impossible, but it would be a lot of work. If it takes you 5 minutes per tooth, that
