(Random Stats and Stuff)
| Stats (as measured within crater bounds) | |
System Map (not to scale)The system is focused on a single, small, stable star approximately mid-way through its yellow burn phase. Planetary arrangement is typical for a low-planet system, distinct form the complex inverted nature of the high-planet-density Earth system. Oort field (not shown) is sparse. Orbits are almost circular and appear stable for the foreseeable future. |

Planetary Internal StructureImpact has an unusually large and dense core made primarily of iron with notably large portions of stable heavy elements (such as lead, tungsten, gold) present, giving it higher gravity-for-size than a planet with a more even mix of elements biased towards the lighter end of the periodic table. It is possibly the core of a gas-stripped ice planet (of Neptune/Uranus size) captured by Green Giant, rather than a native satellite. The planet's interior has cooled to a great degree and the small portion of liquid-iron core results in Impact not having its own magnetosphere, though it is protected by the strong magnetosphere of Green Giant. Low flow rates in the outer core and lower mantle are insufficient to drive plate tectonics. Heat and gases transfer to the surface via relatively small bubbles of heat moving up through the crust, causing high-temperature sub-oceanic vents. The deep crustal weakness around the impact crater have resulted in a dense concentration of vents in this region, as well as moderate bulging of the crust-region of which the crater is part. |

Crater Structure |

Crater Map(1 grid square represents 256x101units2 (409.6m2*)) The central island is my private space for myself and invited guests only. The outer ring is to be more public. Three features marked:
|
 |
| Maximum Terrain Height (from sealevel) | 64x101units (51.2m*) |
| Lowest Terrain Depth (from sealevel) | -64x101units (51.2m*) |
| Mean Planetary Depth (from sealevel) | -32x101units (25.6m*) |
| Day length | 6 hours |
| Equatorial Diameter | 8120dµ12 (0.5 Earths approx) |
| Gravity | 0.258G (0.310G) |
| Pressure (sea-level) | 0.7bar |
| Air Temp range | 16°C - 31°C |
| Sea Temp range | 20°C - 21°C |
| Primitive Count (approx so far) | 200 |
| Resident Population | 1 (ME!!) |
| Outbound Bandwidth (Mbps) | N/A (expected to be 500kbps - ADSL2+ with some upstream left spare for other network activities) |
| Guest Concurrency | 0 (expected to be around 6) |
| Bot-AV Residency | 0 (6 when I learn how to make such things) |
*A NOTE ON MEASUREMENT: Impact measurements are intended to be based on a base-8 measurement system around the 'hydrogen wavelength' (20.5cm or about 8 inches) and the terrain resolution as well as one in-world meter is 4 units, or 0.8m real-world. In SecondLife™ and hence OpenSim at present, one in-world meter seems to be pretty close to 0.8 real-world meters too, which makes it all match up easily (actually I would prefer a 1.6m (8 unit) ground resolution but that would make everything half-sized compared to the rest of the OpenSim metaverse, causing problems for [eventual] visitors).
Quick Conversion Table: |
||
| Local Units | Metric Units | Imperial Units (sorry, USA, these are NOT 'standard' in any way) |
| 1 distance unit | 205mm | 8" |
| 1x101 distance unit (remember, the x101 is in octal, so x8 in decimal) [I'm looking into a more stylised and condensed way to represent the x10n] |
1.6m | 64", 5'4" |
TIME: Weeks are 8 'days' long. I am calling 1 day 4 Impact axial revolutions as 6 hours for a day is too short: consider 1 day as one wake-sleep cycle for a human. Days are divided into 4 light periods and 4 dark periods of (on average) 3 earth hours each, then into sun/moon-rise and sun/moon-set for 90 minute intervals. I haven't needed to define time any finer than that. Weeks are counted in base-8 which is why you will never see a week number with an 8 or a 9 in it (don't worry, you won't have to do the math to follow the story). Impact has negligible axial tilt so there are no seasons or an environmentally noticeable year. I haven't got around to calculating the year from star movements yet - astro' was never a strong field for me at school. The parent-world Green Giant induces quite large tides, particularly when in conjunction with the sun. The wider ocean's waves - driven by a constant strong Star-rise to Star-set global wind - don't make it into the crater in any significant force.
| LaeMi Stats (stats represent my online avatar, not necessarily my real life) | |
| Name | LaeMing Qian |
| Age | 33 (Sol-3 orbital time) *see notes on extended lifespan below |
| Gender | Female |
| Race | Asian stock profile 5 |
| Height | 7.4units (155cm / 5'2") |
| Occupational Specialisation | Mechanical Engineer |
| Bio-enhanced humanity (significant differences to the baseline homosapien) | |
| Two hearts | Moving the DNA for the formation of the Cardio-vascular system to the bilateral site has resulted in two independent cardio-vascular systems. With one heart failed, a bio-enhanced human can continue in a lethargic state. Tissue (even of the stopped heart) is protected and can heal. |
| Improved blood oxygenation | Optimisations to the haem molecules and associated blood machinery result in tolerance to low oxygen (down to 2%) in an atmosphere. |
| Reduced reproductive rate | Female reproductive cycle reduced to quarterly (approx 90 Earth days). |
| Extended lifespan | Cellular repair no longer shuts down with age, instead running whenever resources are available. Aging beyond adult maturity (around 24 years, sol-3) only occurs in malnutrition or low oxygen situations. Improved apoptosis enforcement mechanisms and movement of several genes from the mitochondrion to the nucleus (where cellular repair mechanisms are more thorough) significantly reduces incidence of cancers. A natural lifespan of 450-500 years is typical. |
Probably eventually I will mess with some very basic A-life. No evolution - this is a static snapshot. Mainly to add a bit of variation and interest beyond the day/night cycle and occasional freak weather. :-D
Life is naturally most focused around the impact crater as the lowest level nutrient source is strongest there where there is a lot of crustal fracturing spreading out from ground zero.
All squidies communicate visually (think cuttlefish) at varying levels of complexity from fight/feed/fright to...
Large squidies display very primitive intelligence and language (I might create an option for visitors to be top-level squidies themselves).
There are no land animals as there is not enough landmass to support them. However a few shallow-water plant-likes have been able to diversify to encroach thinly on the land in very sheltered crevasses within root-reach of the water. Also some swamp-tussock and lily-pad plant-likes in the rocky shallows on the star-set side of the crater rim.
