Alternative Calendar

Alternative Calendar: Measured from the landing of the Pallas Republic’s colony ship on SecLand.  Most calendar apps list both the Terran years and SecLand years since then simultaneously, with the genetic ancestral homeworld listed on top.

SecLand has a year of 319 days, during terraforming strategic use of nuclear explosives were employed to accelerate the planet’s rotation to the day/night cycle Terran life had evolved to.  After much deliberation the New Pallas authorities decided to give SecLand a calendar of 15 20-day months and one month with 19 days, at the end of the year.

Every other planet has its own local calendar as well, the apps tend to have an option for manual entry for when downloading one from the mesh isn’t an option.

    Fission or Fusion? If this is a Hard Sci-Fi universe, that sort of thing isn’t really going to work on anything you’d want to live on (side effects may include earthquakes, runaway thermal increases from all the energy you’re pumping into the atmosphere, runaway thermal decrease from all the dust you’re kicking up, fallout, localised weather effects from continued use of nuclear explosives in the same location. If you’re lighting off firecrackers to effect rotation, they’re going to big enough to have some serious side effects. cf

    How long did terraforming take? How big were the bombs? How much was it sped up?


  2. Ahh…’heavy industrial’ terraforming. Remember…if you’re changing rotation, you need to be throwing mass off at higher than escape velocity. You’d be better of with an array of large mass drivers. If the MD packets have small rockets to circularise orbit, you can use them to expand the habitats. This does tend to cancel out the ‘lack of habitat room’ problem as you’ll be putting a LOT of mass into orbit. If you fire at planetary escape speeds you get more bang for your buck but you wind up having to track all the rocks you’ve scattered into local space.

    I’m not sure if the launch plumes would affect the planetary thermal budget. (you’re going to have large hunks of rock coming out of the MD tubes with enough velocity to reach orbit AFTER aerobraking all the way to the top of the atmosphere. It’s going to be hot and loud.

    Sorry if this is hair splitting. As far as I can tell, you’re trying to keep the Science as hard as possible.
