Well, it's inevitable. I did a terraformed Mars, then a terraformed Venus, so I had to string the planets all together. Earth is modified too, though I doubt you'll notice in this view, I shrank the ice, made parts of Greenland and the Palmer Peninsula ice-free and whacked-off parts of Florida, Louisiana and Bangladesh. Global warming and all that, you know. The planets and asteroids are to scale. The Mercury map is kind of crappy and the tiny asteroids are sort of made up with procedural materials, spheres and metaballs (in order, you see Ceres, Vesta, Flora, Psyche and Eunomia.) The promotional message is a lattice based on PSP created text. Yes, the color of the oceans is different on the three habitable worlds. Water doesn't really have a color; it's mostly reflecting the sky and transmitting whatever is growing near the surface. I figure two things: one - the further from the sun, the dimmer the sky, and two - if people are going to go through the trouble of terraforming, then they'll want to keep Venus cool and Mars warm. On Venus, the lighter color reflects more sunlight, lowering the surface temperature (and vice versa from Mars). The story here is a non-sequitor, but something I made up while working on Venus. I did some basic calculations on the amount of energy it would take to give Venus a 24 hour day. If I did it right, it turns out to be about 6 billion terawatt years (Earth now produces 15-20 terrawatts). So that's a lot of power, even for a future where medium size-spaceships produce multiple terawatts for propulsion. But the energy is based on the square of the rotational velocity, so a 240 hour day would only *ahem* only require one hundredth the energy. (note: if all those 10,000 comets I mentioned previously were to hit just right, they'd only produce a millionth of the energy required to spin up Venus). So here's the story of the Venusian Calendar. --- At the start of colonization in 2260, bombardments, atmosphere launchers, magnetic coils and HSPG generators had increased the rotation period of Venus to yield a day of just over 250 hours. The intent of the VTA was to eventually decrease this period to 24 hours, though that would take centuries at current power levels. After the fall of the Confederation and the damage inflicted by the Secession War, the rotational generators retained only limited and degrading capabilities. The coalition of operators that took over the VTA's equipment managed to keep some machinery running until 2432, when the sunrise-to-sunrise rotational period of Venus reached exactly 192 hours (retrograde). This allowed for a Venusian day of exactly eight standard days. And so, with the Calendar Reform of 2441, the Venusian Long Day, became the local week. Twenty-eight Long Days (and a fraction), became the local year, a period not normally noted, as Venus's obliquity and eccentricity were not significant enough for seasonal variations. A standard year contained forty-five and two-thirds Long Days, an inconvenient measure that kept the Long Day cycle out of synchronization with the standard Common Era calendar. Venus became divided into eight time zones, each with its own Long Day cycle. The Long Day begins at local midnight and has eight named days: Dark, Cold, Dawn, Morn, Heat, Storm, Dusk and Chill. In most locales, Storm (named for the monstrous storms that grow over the course of the Long Day's daylight hours), Dusk and Chill are considered "weekend" days. The Long Day that starts after the first day of the standard year marks the annual Holiday, a period that stretches for fifteen standard days as the party slowly moves with the revolving planet. --Rushkull's Tourist Guide to the Planets, 2504 edition.
