Massive gravity effect

[rgrove0172]

Your an earth-born human on your first trip to King (Gravity just over 3Gs)
As your ship descends you;

A) feel an unpleasant heaviness as you near the ground and find once disembarking you are almost immediately exhausted, straining just to move around. After about an hour you are forced to accept the offer of a motorized cart by your hosts to continue your tour.

B)feel an oppressive weight building as you descend and upon reaching the ground realize you can barely breathe, much less move on your own two legs. The crew administers oxygen and places you on a cart to carry you to your destination where you will have to conduct your affairs under constant assistance and supervision.

C) pass out, your circulatory and respiratory system not able to maintain circulation under the extreme mass you are suddenly subjected to. You are quickly returned to orbit and a replacement with the King augmentations sent for to replace you.

Probably A. Although King has high gravity, the exertion somewhat is offset by the oxygen-enriched atmosphere.


The sea-level air pressure is 2.7 atmospheres @ 19% O2, so the absolute partial O2 pressure is 390 mmHg sea-level, compared with Earth's 159 mmHg. This level of enrichment is approaching long-term toxic levels. Such an atmosphere should be easily breathable, but the CA says the opposite.
In fact, the atmosphere is flame-enhancing according to some old fire code (I don't have the source) that says an atmosphere is fire-enhancing if the O2% > 23.45/sqrt(atm).

How significant amounts of sulfur gases exist in such an oxidizing atmosphere another can of worms.

Depending on how re-entry is done, you may experience more G's during that and then they'll lessen to the 3G of the world.

But I'd agree with "A", you're gonna get pretty beat, pretty quick. You may well never recover -- I think the G's would be terribly oppressive. Simply too much load, too soon, for too long.

Now, if you were traveling on a ship with spin induced G, it would probably be smart to increase that incrementally during travel to help acclimate you better once you arrive.

I suggest checking out the "Human Tolerance for Gs" thread on the Mongoose Traveller forums for a discussion that might provide some useful bits.

The space shuttle does/did 1.7Gs to 3 G's during the different fazes of the takeoff.
Early experiments at 6 g for 10 minutes produced no long lasting medical issues. Tolerance was quite subjective, with only the most motivated non-pilots capable of completing perform simple physical and communication tasks. (Traveller Adventurers)

Most of the info I find is on long duration zero G. Part of the testing for reducing zero-g muscle loss included subjecting people to 2.5G's for an hour a day.
Granted, this still isn't that long.

I can't find results for more recent centrifuge testing for long distance space flight simulation but I'd guess, even at our current tech level, a properly medicated, trained and equipped person could handle 3Gs for several hours without any major medical issues.

Necessity is the mother of invention. I believe as the need grows and space flight to Mars progresses, the research will advance and the level of function and the length of duration will both increase, as will the amount of g-force.

For the King example, an anti-g suit could have medical monitoring with wireless data feed built in and a vehicle to keep a persons body in the optimal position might be needed.

You wouldn't just step off the ship and walk to the local watering hole. lol

Technically (Core Traveller Rules and MgT2300) King's gravity is just considered Heavy G and hense yields a modifier to individuals from a planet with lesser gravity. I would agree that its an extreme situation and perhaps double those modifiers and implement some sort of exhaustion rules but Im not certain, from what Ive, read that complete incapacitation, especially in the short term, is appropriate.

No offense intended but Ive known a few 600 pounders and they arent very comfortable, arent running laps, and need assistance to get around - but they do.
