Default Rimward Bound

The background to my own Traveller Universe.

MANKIND TO THE STARS

When mankind’s diaspora to the universe began, it started slowly. The early hyperdrive ships could only travel a parsec in a month, and the time lag hindered rapid response to any problems, if indeed, any knowledge of such reached Earth. However, the realization that interstellar drive testing needed to be carried out at a distance from a mass concentration such as a planet or large star led to the swift development of first the Jump One drive and then Jump Two. The ability to cover a parsec in a week massively speeded up communications, and the initial diaspora began. Begun first by governments, and then with reports of other inhabited planets, large companies, the majority of ships headed toward the Galactic Core, seeking inhabitable planets and trade with the newly discovered galactic civilizations. While the improving hyperdrive ships did the initial scouting, the ability of the Jump Drive ships to respond quickly soon displaced the slower hyperdrive vessels to strictly long-range exploration and scouting.

This replacement of the hyperdrive by the Jump Drive had an unexpected side effect. The hyperdrive ships, especially the slower ones of one parsec a month were sold off cheaply, but with a different class of purchaser. No longer the preferred choice of the large government or corporation, the purchasers were small countries looking for places for their growing population, and small groups looking to escape what they viewed as the restrictions of an over industrialized society: society’s misfits, the malcontents, the discontented, and the adventurers. These groups, especially the small groups looking for planets to call their own, headed not for the Galactic Core, but for the Galactic Rim, seeking unexplored areas or those with no prior inhabitants to contest a claim of sovereignty. Small companies, realizing that the was a demand for knowledge of the Rimward areas, purchased surplus hyperdrive exploration scouts or small surplus trading vessels, and began to head deep into the Rim. The number that did not return simply added more than a bit of spice and adventure to the Rim Scouts, as did the fictional exploits portrayed in prose and video. Tales that became all the more tantalizing by discoveries of vanished civilizations and ruins of much earlier space explorers.

While many of the colonizing efforts failed, or were marginal successes, some did flourish, and provide encouragement for even more efforts. Slowly, out into the Rim, a network of settled planets and way stations developed, giving the Rim Scouts rest and repair bases in the Rim, allowing still more distance exploration. The way stations also functioned as the trading forts and posts of the American Frontier, giving a rest stop for small colonizing groups heading deeper out after unsettled or presumed greener pastures. The efforts by smaller planetary governments to establish colonies deep in the Rim encountered the inherent problem of communication lag, and the colonies rapidly grew to separate from the founding country, while still maintaining relations with it.

Default Rimward Bound (Continued)

Not all groups were peaceful though, as one group of Icelanders along with Norwegians and Swedes set out to create a modern version of the Vikings, heading for areas near where the lion-derived Aslan had been found, but not above raiding human planets as well. Their use of long-range hyperdrive ships, covering a parsec a week, gave them the ability to strike a great distance from base, beyond the ability of even Jump Six ships to strike back. Raids taking several months to accomplish would be tolerated if the return was good.

As exploratory ships penetrated deeper into the Rim, odd reports began to filter back, of strange contacts and inexplicable occurrences. One ship suddenly came out of hyperspace at Terra itself, with the crew having no memory of their most recent voyage, and only incoherent garbage in the ships computer drives. The only thing known was that the scout had departed a base 85 parsecs to the Rimward of Terra several weeks prior to its appearance at Terra, heading out into the Rim. Another ship reported a “lost colony” of humans, claiming to have been transported from Terra by unknown means to a watery planet over two sectors from the Solomani Sphere, but attempts to bring a few of the so-called “Terran” colonists back were defeated when the colonists disappeared from the scout just prior to entering hyperspace, while again, the records on computer drives were a hopeless, contradictory jumble. The scout’s crew at least had their memories, and reported that one consistent report of all of the possible Terran was that they or their ancestors were in the vicinity of an area of Terra called “The Bermuda Triangle” when they suddenly found themselves elsewhere.

Default Hyperspace Drive vs. Jump Drive

Hyperdrive verses Jump Drive in My Traveller Universe.

Jump Drive functions pretty much as Classic LBB/The Traveller Book/Starter Traveller, with a couple of changes. First, the power plant number has to equal the number of the maneuver drive without regard to the jump drive. A Maneuver drive of 1 requires a Power Plant of 1, whatever the ship requires, while the Jump Drive can be of a higher level. So one could have Power Plant 1 and Maneuver Drive 1 of "E" for a 1000 Ton ship, along with a Jump Drive 2 of "K". This would add up to 80 dTons of volume, leaving an additional 85 dTons of unused engineering space to be put to other uses. The fuel required for jump stays the same, while Power Plant fuel is 1dTon of Liquid Hydrogen per power plant number per year, while Maneuver Drive fuel is 10 dTons per Maneuver drive number per Jump.

There are two types of Hyperdrive that can be purchased. Hyperdrive-1 covers a parsec a month, and corresponds with Jump/Maneuver/Power Plant 1 in the construction charts, while Hyperdrive-2 covers a parsec a week, and corresponds to Jump/Maneuver/Power Plant 2 in the construction charts. However, the Hyperspace Drive Two requires twice the mass and costs twice as much as the corresponding Jump Drive, and must have a Power Plant of 2 to maintain the hyperspace field in hyperspace. For example, a 1000 ton ship using Hyperdrive 2 would require a Drive "K" needing 110 tons of space and a Power Plant "K" requiring 31 tons of space. A Maneuver Drive of "E" would give one G of acceleration, and require 9 tons of space. The total volume required would be 150 tons of a standard hull design of 165 tons, so 15 tons could be used for other things. There is no requirement for additional Liquid Hydrogen for a Hyperspace Bubble, For Hyperdrive Operation, the Power Plant will use 0.1 (one-tenth) the mass of the ship per year of operation of Liquid Hydrogen per drive number. The would mean that a Hyperdrive 2 ship of 1000 tons would require 200 tons of Liquid Hydrogen per year of operation, while a Hyperdrive 1 ship of 1000 tons would require 100 tons of Liquid Hydrogen per year of operations. The Power Plant fuel requirement is 1dTon of Liquid Hydrogen per year per power plant number for ship's power, and the Maneuver drive fuel requirement is 20 dTons per Maneuver Drive number per month. Note, the ship does not use the Maneuver Drive while in Hyperspace.

I like what I am seeing. Did some of the bigger governments or corporations sponsor or fund the 'misfit' settlements to create markets for goods/services?

The problems the government-sponsored colonization efforts ran into were primarily two-fold. First, the communications lag, especially early on, forced the issue of the local government having to have a large amount of independent decision making, which was accentuated by the second factor. That was the persons sent out were either conscripted to go, and therefore were not exactly happy, or they were the ones already discontented with the existing status quo. The resultant combination led to rapid movements for independence from the "mother country". The country-supported expeditions also headed towards the Core, with the possibility of contact with other star-faring groups, the Rim did not look that inviting.

Corporation efforts only worked if the planet was sufficiently dependent on outside support, i.e. was not really habitable without outside shipments, and focused a lot on rare resources. Again, they also headed coreward.

The colonies founded by the "misfits" in many cases were opposed to large corporations or governments, and in some cases were also anti-technology. Think of Amish and Mennonite groups looking for new areas to spread out with their large families, or historic re-enactors looking to really turn the clock back, or those fed up with the constant irritations of overly-populated areas. Then you have that certain number who simply like to look out and not see another sign of human life, or who prefer the smoke of their nearest neighbor's fire to be a couple of miles away. Then there are the romantics who think a water world makes a great case for recreating the Golden Age of Piracy, as long as you can get someone to be the pirated.

You also have the planets where conditions are tough, but the tough can make a go of it. Read "Four Day Planet" by H. Beam Piper at Project Gutenberg to get an idea of that.

And then you have the really "odd" planets.

PP and MD fuel should be based on plant/drive size (dT or letter) rather than resulting power/maneuver rating. It takes more to power and move a large ship than a smaller ship.

That's my two CR.

The Power Plant operation during hyperspace is based on the displacement of the ship. As Hyperdrive operation could be extended, that is going to use up Liquid H at a fair rate. If the ship is in orbit or on-planet, then Power Plant operation shifts to 1dTon of Liquid H per year, again as orbiting or on-planet could be extended. If a ship is will to pay say 10,000 Credits for a cubic meter of Heavy Water, that would supply for more than a year. For a ship to have 10 Megawatts of power available 24/7 for an entire year would take 51.65 ounces of Deuterium per year.

The would mean that a Hyperdrive 2 ship of 1000 tons would require 200 tons of Liquid Hydrogen per year of operation, while a Hyperdrive 1 ship of 1000 tons would require 100 tons of Liquid Hydrogen per year of operations.
I will take your comments on the Maneuver Drive under advisement, and look at it again. The problem is a lack of real coordination be the displacement of a ship, and its actual mass.

I greatly appreciate any comments.

Back working on this, and as usual, my brain works best at night, like the middle of the night. For my Piper-Norton Out Rim Sector, I now have six out of sixteen sub-sector planet names laid out, with notes for some of them. I sort of do things in reverse, naming the planets and figuring out what they might be like based on the name, and the mapping them and adding the world profiles, which may or may not be randomly generated, as least completely. As this is a work in progress, some of my earlier ideas might have changed. I need to go back and re-read them.

The progress so far is Sword, Castaway, Kalevala, Aegir, Warlock, MacBeth sub-sectors are coming into shape, Aegir, named for the Norse Sea God, has a lot of water worlds, while the Kalevala, Warlock (what would you expect), and MacBeth sub-sector tend to be a bit "odd" at times. Then somewhere there is a wormhole which can toss a ship to an alternative universe planet, like Barsoom (John Carter of Mars meets Traveller) or the original version of Space: 1889 or the universe of H. Beam Piper.

The thing with naming the planets first is that I start getting a picture of what it will be like, and can start writing up the planet description, as I have done with El Paso. Each sub-sector will have between 13 and 20 planet locations, but may actually have more than that many planets possible, so that the Game Master can customize the sub-sector the way that they like. The idea is to make it as wide open as possible.

Considering how far rimward of Earth the sectors are, is there like a big gap of space in-between the Terran Confederation and the Piper-Norton sectors? Or are there like small groups of people one might find along the way to-and-from on the path?

Also, considering hyperdrives are a thing IYTU, were they a Terran-only invention or were they something other races or human groups had produced prior to Terrans bursting on the scene?

Well, I had planned to locate it just rimward of the Ahriman sector on the Traveller Map. However, pretty much the entire human rimward area has been pre-empted by another individual, so that idea went out the window. Now, I am going with it located about 100 to 150 parsecs to the rimward of the Solomani Sphere, in an alternate Cepheus Engine Universe, and avoid the Traveller Map entirely. The assumption will be that there are a string of planets and refueling stops reaching back to the Solomani area, but I do not plan on trying to set up all of those sectors too. I am already looking at putting together a block of 4 sectors as it is.

The Terrans developed the Hyperdrive-1 a little prior to the Jump Drive. The experience with needing to use the hyperdrive outside of the gravity well of a planet gave them the key to the Jump Drive, also needing to be used out of the gravity well of a planet. The Jump Drive was faster, needing only one week, but the hyperdrive could take one a lot farther, so was used for the initial exploration of an area, with the Jump Drive powered ships following.
