Re: Housekeeping
For SpaceNut re #3976
Thanks for porting the image links! They look good! I will try to port more images today.
FYI ... with a little help from Gemini, I just found a candidate Crater for Calliban's dome structure.
GW Johnson has an idea for a different building design, and there is a Crater near to the one I am proposing for Calliban.
For any NewMars member who wants to try their hand at designing a habitat that would fit inside a crater, there is a nice BIG Crater nearby.
We have thousands of craters scattered across the landscape, so there is plenty of room for everyone to set up shop in a crater, let alone on the plains nearby.
I'll post the report shortly in City.
Here is an image of craters on Mars that might be suitable for development my NewMars entrepreneurs.
I doubt any other humans have their eyes on these particular craters.

If anyone is interested in seeing the craters, a short cut is to call up MRO CTX, 22n048w Mosaic
Apparently that is a set of data taken to show the bounded region in middle range resolution.

Re: Housekeeping
So where is it relative to what we have already sent landers to.

Re: Housekeeping
For SpaceNut ... the crater of interest is 59 kilometers from Viking 1.
The round dot that indicates the site of Viking 1 is large enough to include both Viking 1 and the crater-of-interest.
You can see a similar indicator by activating the high definition section for the Viking 1 site.
As you probably saw in the post about Viking 1, the site was chosen for safe landing, after the original scientific destination was found to be too dangerous.
Please consider putting the image you showed us in Post #3978 into the City topic, along with the text that the proposed crater site is 59 kilometers away.
I've made a mental note to try to create an image that shows the two in one snapshot.
Update: I think the crater is inside the round dot that indicates the Viking 1 site in the image you showed us.

Re: Housekeeping
For SpaceNut ...
Your interesting new topic about "boing" may be about Boeing? or perhaps about Boring ? .
Or perhaps it is about the sound of a spring when it is released?

Re: Housekeeping
Done as I did not see it but the topic is to collect types, mass and more for the equipment that is needed to be sent to mars.

Re: Housekeeping
For SpaceNut re #3981
Thanks for changing Boing to Boring !!! It ** does ** make a difference for future readers!
Regarding dump trucks ... http://newmars.com/forums/viewtopic.php … 13#p236013
This forum spent quite a bit of time thinking (and writing) about power for heavy equipment on Mars.
Your posts show Earth equipment. Mars equipment will look ** very ** different.
It is possible you have forgotten all that work, although I'm sure you read it at the time it was created.
Each vehicle that uses piston engines on Mars will have to carry oxygen and compressed oxygen is more likely to be the mode than liquid.
My recollection is that the consensus was that simple CO and O2 gases are the most cost effective practical fuel combinations for Mars. All the fancy talk about hydrocarbons is just that. The economics of creating hydrocarbon fuels while still having to carry oxygen just don't make sense.
Your AI friend may be able to create images of dump trucks for Mars, with huge tanks for fuel and oxidizer.
At one time we computed the ratio of size of tanks. I think it was two to one, but I don't remember which was which

Re: Housekeeping
For SpaceNut re CO2 topics ...
Recently we've seen renewed interest in CO2 reduction ...
CO2 is a critical capability needed for Mars, and this forum has an opportunity to establish a store of knowledge.
This forum was established as an entertainment concept, and long term value was (apparently) not included in the early vision.
We do NOT have to be bound by the early vision ... in fact, I think it is clear that the early vision has run it's course. It worked for 20 years and a bit more, but now we have an opportunity to go beyond that starting point.
I would like to have a repository of knowledge about all the different ways CO2 might be processed to create useful products.
Ideally the advantages and disadvantages of each method would be listed in useful detail.
The investments needed to create a particular method would be given, and the costs of maintenance and sustained operation would be estimated.
In short, a person or group planning to set up shop on Mars would have a resource available to quickly help them decide where to put their money, time and effort.
Here is a list of the topics we have now with CO2 in the title:

A complete system would include:
1) capture of CO2 from the atmosphere (inside or outside of habitats)
2) production of CO and O2 for stored energy applications (ie, trucks, vehicles, generators, other)
3) production of pure carbon for advanced manufacturing such as hydrocarbon fuels or nanotechnology using carbon
Other I haven't thought of?
