I see that the normal newmars website and the clone has a debugging code at the end that creates the Query.
The html page normally would end with the classic source code
</div>
<div class="end-box"></div>
</div></body>
</html>
but instead the clone contains at the last </div> between the <body>
<p id="debugtime">[ Generated in 0.020 seconds, 7 queries executed - Memory usage: 561.17 KiB (Peak: 579.96 KiB) ]</p>

so on and so forth until the query ends with the html body end structure.

So, if we can do what we have done with registration and spammer account conversion then there is no reason from what I have seen to turn it off as we have done here.

I only marked a spot for a forum that delves into how we get the water on mars under the project forum category.
The large ship is a specific topic are with many others that will be required for a manned landing of vehicles to the surface for manned exploration.
Since we must make fuel for a large ship to be reuseable on mars it sort of is a support topic.
Also we could be a business proposal to support such a large ship.
I do not intend to redo all of the work that newmars has as we keep doing with repeating the why choices are made in any new version of os that we can migrate too.

Seems others are thinking bigger for the ship to rescue Nasa's mission.
Experts Suggest Using SpaceX's Starship to Rescue Stranded Samples on Surface of Mars
Needless to say, a rocket that could both land and lift off from the Martian surface could help streamline the endeavor significantly.
While nobody really knows if Starship could ever be used to collect samples from the Red Planet — SpaceX has yet to even get it into space and back in one piece — it's a glimmer of hope for an expensive mission with a spectacular potential scientific payoff.
"There are aspects of solar system evolution that can only be done through the return of samples [from Mars],” Brown University planetary scientist Jack Mustard told SA. "Having datable samples from another planetary body to address that question would be unbelievable."

I have taken a look to see if there are Fluxbb data sets to those of phpbb3
https://github.com/fluxbb/converter
How to convert from FluxBB 1.5.11?
There are many posts for this on the web "converting fluxbb posts to phpbb3".
#1809 Re: Meta New Mars » Housekeeping » 2024-04-21 15:19:26
It means they can actually read and make sense of what we are doing.
#1810 Re: Unmanned probes » Low cost Mars Sample Return. » 2024-04-21 15:16:35
One of the issues is the time to retrieve all of the samples that are lying on the surface. That makes robotically done a long period as due to the telerobotic time delay that are required for programming any movement.
That means fuel boiloff since oxygen required for most will need active cooling.
Solids due change this in the design but duration will it affect it during the waiting period on the cold mars surface waiting.
We know that we require navigation, heat shield but is a sky crane the means to the end or do we really need a capsule or landing platform.
So that is a many stepped process but once we put numbers to what is required and not its cost from the bloated cost plus companies.

It is here that Mars_B4_Moon has the bragging of China which could strive to do what we can not. With a response that follows by Oldfart1939 more convinced that Elon could do it with Flacon 9 Heavy Red Dragon.
We even were close to designing something along the same lines to go to mars but it's about wasting money. with the current clasic Nasa RFP and contracts.
#1813 Re: Unmanned probes » Ingenuity, Scouting Mars by Helicopter » 2024-04-21 09:07:59
It outlasted expectations of a first attempt in its design.
Learning from the many lesson's changes can be made to improve the design.
It might make the sample return more likely with a sample retrieval being done by an improved helicopter.

Nasa expenditures for an end-to-end system is failing due to costs. In the end it had to many parts and partners to be able to make it happen.
A study from July 2020 estimated the total cost of MSR to be between $2.5 and $3 billion.
NASA had hoped that Mars Sample Return would cost $5 billion to $7 billion, and that the rocks would arrive on Earth in 2033. But last fall, a panel that reviewed the mission concluded that the cost was likely to be much higher, from $8 to $11 billion.
A new date of 2040 is even more costly.
Based on topic start of 2012 its got to be even older than this.
https://en.wikipedia.org/wiki/NASA-ESA_ … ple_Return
Seems even 2001 was the beginning.
Nasa is also looking at not a rover retrieval of the ready samples means a possible Sample Recovery Helicopters
This still needs a MAV and lander pltform for the helicopter to make use of.
We are talking about how much money has already gone under the bridge.

How Texas unleashed a geothermal boom
On Wednesday, startup Bedrock Energy unveiled a new geothermal-powered heating and cooling system at a commercial real estate complex in Austin. Earlier this month, next-generation drilling company Quaise — which uses high powered radio waves to drill through hard rock — filed a permit with the state energy regulator to begin field testing its drills, years ahead of what industry insiders had thought was possible. Houston-based Fervo is building a 400-megawatt project in Utah. Military bases across the state are looking into geothermal as a potential source of secure electricity in an era of price spikes and cyberattacks.

With data at work, I make use of Access to combine related tables so as to remove the items not required to give a fresh view of that information. It also is a means to design a new layout for that data as you can copy a view of information that is created in new tables or export it.
In either case its hours of work ahead of the task to bring NewMars into the more modern application.

Even older as its from Two MIT graduate students in civil and environmental engineering have won a 2006 grant for Lesotho solar generator
Initially incubated in MIT's D-Lab class taught by Amy Smith, an instructor in the Edgerton Center, the MIT solar micro-generator won numerous awards before receiving the World Bank grant. The micro-generator team -- known as the Solar Turbine Group -- has already worked in Lesotho with BBCDC and local engineering students. Mueller, who joined the team this year, went to Lesotho in January with Orosz and team member Perry Hung, a sophomore in electrical engineering and computer science. Mueller and Orosz will return there for nine months in September, with team member Elizabeth Wayman (S.M. '06). Their advisor, Harold Hemond, the William E. Leonhard Professor of Civil and Environmental Engineering, provided "insightful suggestions along the way and trusted us to strike the right balance between our graduate research and our commitment to making this project a reality,

Its been a while since I posted what the cost for fuel is in my area.
It has been on the usual rise for the holidays of the summer.
Switching from winter fuels to the summer blend ways has this plotted course.
Its current price as of yesterday is $3.65 a gallon.

I was able to log into the Fluxbb site on Azure as the password table was present.
When it errors and goes to the newmars address go back 2 pages and refresh and you are logged into the Azure site.
The forum page has this across the top of the page.

You already showed that the current fluxbb can be brought over with its tables so modifying the tables to go into the new format should not be a problem.

I would like to migrate our topics, if possible, to the new phpBB3 platform if possible since we are able to save the data into excel then we are able to move the topics into the correct locations in the new data base structure.
I am sure we still need more time to explore this.

There are almost always variables within any design that allow for changes in a commercial design that others could buy once being mass produced for off the shelf use.
Everyone has the ability to make use of the sun, wind, water and fuels but the path to the desired end is where true engineering minds shine. As it's that outside of the box thinking that makes the impossible possible.

Here is an example of what MIT also has been designed with numbers for performance coming from it.
This is close to the average homes power levels for use as the output is dependent on the power generations spin.
There are 4 troughs that create 10kw to create 200 to 300 gallons of hot water and 1 kw of electrical power with crude auto parts.
Here is another view of the troughs collecting heat energy
Sure, the working fluids are different which changes the items due to pressure as well as the heat range.

For SpaceNut ....
Thanks to your leadership, our forum is free of hacker attack successes.... We are still being attacked by bots every day and every minute of every day, but for several years now not ONE of those bots has penetrated the strong defense you set up.
However, Dr. Lewis Dartnell's older phpBB forum is under serious attack and the hackers have found a way to promote themselves from Newbee to Regular Member. I've notified Dr. Dartnell, and he responded recently to acknowledge the situation.
Below I will show the status of the Knowledge forum as of a few minutes ago. I'm planning to post similar messages to show the progress of the assault. Eventually I assume/hope Dr. Dartnell will decide on a response. In the meantime, the number of fake members is growing at the rate of hundreds per day.

In our multiple initiatives to investigate options for the forum, we have the opportunity to investigate whether we might be able to characterize the "guests". There may be a way to determine if they are human or bot, but at this point, I don't know what such a method might be. Analysis of the IP address ** is ** possible, and we could easily report the country of origin of each "guest". Google does something similar with it's web site reporting tool.
Come to think of it, we might be able to install the Google web site reporting tool. We set that up for the Living Universe web site, and it produced interesting results.

For SpaceNut re Turning off Registrations...
If you will document how to do that, I'd be happy to forward your instructions to Dr. Dartnell.
As you do so, please keep in mind that it has literally been years (since 2018) that he opened a session on the Knowledge forum.
Your advice needs to be written for someone who has forgotten almost everything about how to run the site, and in any case, never knew how to shut off Registration. While you're at it, please find out where the text we see at our Registration page is stored. That needs to be changed to point to our new registration procedure, and now that we have a Webmaster (kbd512) we can change it. (Assuming you cannot, which is possible).
