If you are interested, the concept is for a participant to take responsibility for development of a virtual plot on Mars, one kilometer square on the surface, in a community called Sagan City (2018).
Participants will interact with each other to specialize in one or more of the knowledge areas which will be needed to sustain civilized life on Mars.

In addition, tahanson43206 is participating in a membership outreach campaign at NewMars forum. In an effort to build up a virtual business community focused upon Mars, messages are being send to newly registered members, inviting them to participate in the Hacienda topic.

A new branch of the My Hacienda topic is open, in addition to the previously reported Devon Island branch. This new branch considers an implementation of Sagan City (2018) on an island in Norway. This island is inhabited, and international arctic research stations are already encouraged by the government.

In the past week, a variety of topics have been under discussion as usual.

Work has proceeded in discussion of a gas-only rocket vehicle for Mars. The topic was speculative from the outset, and it is on life support, but it is not yet expired.

Meanwhile, a branch of that topic was opened for the Lunar launch environment. The gravitational force to be overcome is about half that of Mars, and there is no atmosphere to impose drag on the ascending vehicle, but the fuel most likely to be available is hydrogen, and that is (said to be) more difficult to work with than methane, which would be the likely fuel on Mars.

In the past week, a variety of topics have been under discussion as usual.

Work has proceeded in discussion of a gas-only rocket vehicle for Mars. The topic was speculative from the outset, but it has morphed into what appears to be a potentially productive line of inquiry. GW Johnson has made clear that it is unlikely to be practical to build a rocket on Mars that can reach orbit while powered by fuel and oxidizer held onboard in gaseous form. By a series of posts, GW Johnson has succeeded in making the case for continuing the terrestrial practice of using liquid components for launches from Mars. The new direction for the topic arose from a reflection by SpaceNut that the British Sabre engine design achieves (what to me are astonishing levels of) cooling of incoming air using a cooling system which circulates liquid hydrogen. This insight led to discussion of the possibility of gaining some advantage on Mars, by storing oxygen in gaseous form (which does not require constant cooling) until a customer shows up in need of liquid oxygen for refueling a spacegoing vehicle (or for any other purpose which requires liquid oxygen).

Specifically, the discussion moved in the direction of considering liquid CO2 for high speed cooling. That discussion is still under way, because the problem of moving from dry ice to liquid CO2 at 5+ atmospheres is not obvious.

GW Johnson recently posted a set of lists of titles of essays he's written about various aspects of rocket technology.

In the past week, a variety of topics have been under discussion as usual.

A member with the ID RobertDyck added a sketch of a large Mars transport. His work comes at a time when GW Johnson has been writing about a variation of the Aldrin Cycler concept. The variation of GW Johnson has the distinct feature of being planned, not for a regular cycle of movements between Earth and Mars, but instead a high speed trip to Mars with a guaranteed safe return if a landing (or stopover) at Mars is not possible. This design appears to share the characteristic of a rapid (under 167 days) trip to Mars that is a part of the Aldrin Cycler concept.

This plan will require more propellant to slow down at Mars, than would a trip by "normal" Hohmann trajectory, but it will deliver passengers to Mars about three months sooner.

The RobertDyck sketch shows a vehicle designed to provide artificial gravity for the passengers and crew, as well as radiation protection provided by a layer of water carried in the wall of the vessel that faces the Sun.

There is a summary of the Large Colonization Ship topic available, followed by a debate (of long standing) over the best way to slow a large space ship at Mars. One option is aerocapture, but that option is extraordinarily dangerous. It is also unnecessary, because Phobos is more than capable of delivering 2 km/s (or so) of velocity increase due to the unique nature of its orbit.

Work is progressing (slowly) on design of a piece of hardware to sit between loops of Kevlar Thread, in a chain concept for a tether at Mars. Models of the Cushion Guide are shown in various stages of development at Shapeways.com. A full version of the model is in contract for 3D printing.

Update 2020/08/02 .... This topic was originally intended to include development of ideas for a designed planet, while at the same time it followed the Magellan expedition for the three years of that epic undertaking.

Early on, it had been imagined that a planet could be adapted for human use by starting with a gas planet with 1 gravity at the surface of a sphere surrounding the gas. Such as planet would be able to provide a supply of fuel for fusion.

The default condition for such a planet would be a heated interior, left over from the energy imparted to the object by infalling material. Thus, the gas would be in a gaseous state, and the surface sphere would be in danger of falling into the gas.

Today it occurred to me that if heat were not present, then the gas might exist in a liquid state. What is ** not ** clear is whether the interior being liquid would make any difference for the flotation of surface elements.

My guess, without referring to a table of properties of the elements, is that the density of liquid hydrogen is insufficient to support any heavier element that might be brought into contact with it.

The major new element added to the discussion (by the new member (SeaDragon) was the idea of making pylons out of frozen Mars regolith.

Such pylons would need to be protected from daytime heating near the equator during Mars summer, but the mean temperature at the surface of Mars is -81 degrees Fahrenheit (per mars.nasa.gov), so the pylons should be able to hold form reasonable well over the course of a Marian year.

Such pylons would need to be protected from daytime heating near the equator during Mars summer, but the mean temperature at the surface of Mars is -81 degrees Fahrenheit (per mars.nasa.gov), so the pylons should be able to hold form reasonable well over the course of a Marian year.

Update 2020/08/07 A NewMars member going by kbd512 came up with an idea/suggestion for a deep space vehicle that I have not seen before, and that I think is worth exploring a bit.

The idea is to build rotating habitat disks that rotate in opposite directions, like the propellers of helicopters designed with counter rotating blade disks.

The unique aspect of kbd512's concept is to use the Startrek Enterprise saucer design for the rotating habitats.

Engineering challenges to design such a passenger carrying vessel would be significant. Navigation of such a vessel would be challenging as well, although counter rotation of the habitat sections would presumably help, the forces at work at the hubs would be severe if thrust is not applied carefully.

*** Update 2020/08/09 ... discussion of the Startrek(like) vision of kbd512 has stimulated discussion leading to an interesting concept not published elsewhere, to the best of my knowledge.

A member posted a link to a Physics instructional video about gyroscopes. This lead to the realization that a very efficient design for a spinning habitat with a non-spinning propulsion/navigation unit is possible.

Whereas a gyroscope used for position sensing in an aircraft has three circular housings that are at 90 degrees with respect to each other, a space vehicle would need only one ring, and only half of a ring at that.

A 3D Printer model showing what this spacecraft design might look like has been published on NewMars forum.

This is the subreddit of the Living Universe Foundation. Our dream is to see humanity take life to the stars.

In NewMars.com (forum) there is a post which is following Mars around the Sun. New Years on Mars occurred on Earth day 2019/03/24. Mars has passed longitude 180 degrees in its stately progression. The calendar is now on Sol 383 or later.

If you are interested, the concept is for a participant to take responsibility for development of a virtual plot on Mars, one kilometer square on the surface, in a community called Sagan City (2018).
Participants will interact with each other to specialize in one or more of the knowledge areas which will be needed to sustain civilized life on Mars.

In addition, tahanson43206 is participating in a membership outreach campaign at NewMars forum. In an effort to build up a virtual business community focused upon Mars, messages are being send to newly registered members, inviting them to participate in the Hacienda topic.

A new branch of the My Hacienda topic is open, in addition to the previously reported Devon Island branch. This new branch considers an implementation of Sagan City (2018) on an island in Norway. This island is inhabited, and international arctic research stations are already encouraged by the government.

In the past week, a variety of topics have been under discussion as usual.

Update 2020/08/17: A friendly competition is developing between RobertDyck and tahanson43206 for design of an interplanetary space craft able to carry substantial numbers of passengers while providing 1 g of simulated gravity, protection from radiation (especially Solar flares), and a level of comfort for passengers comparable to a first class cruise ship on earth.

The two visions differ in so many ways that their development in the months ahead should be interesting to follow.
