This is a nice start to the Lagrange figure. There are Lagrange points that are small and unstable. Also, there are Lagrange areas that are vast and stable. Each planet has this situation going on with the sun, but also each moon with its planet. This means mars has lagrange points and areas with the sun, and the moon also has lagrange points with earth, and so on.
One might easily ask what’s the meaning of all this. Well, the point is simple. This is where to build large things in space. The stability drastically decreases station-keeping fuel, mitigates various risks inherent with space, and has other advantages.
To be more blunt: The Earth-moon Lagrange 4 and 5 are very important locations. They’re where people would live in space if there were lots of them, a great many of them.
The scanned page from a textbook that was the previous oceanic depths figure has been upgraded. Now its not so boring.
Algae aren’t given credit for their share of the work they do. 90% of all photosynthesis on the planet (earth) that happens is done by algae, not trees. Most algae are in the ocean, and they eat nutrients that are in the water. However, most of the nutrients are in the depths. The reason the entire ocean is not abloom with algae is because the algae only bloom when the water is whipped up from the bottom by currents. The algae are eaten by krill, krill by fish, etc. and the fish livestock are kept fed. One ‘proposed’ method for controlling the CO2 is using the ocean to absorb more of it with algae blooms. An interesting character, Russ George has fertilized the ocean to see if this works. Apparently, there are many ways to feed the fish.
Think about GEO, or Geostationary, orbit as a place just slightly past LEO (low earth orbit). It takes a massive amount of energy to get from ground to orbit, but the height is only 200+ some odd miles. However, GEO being 22,000 miles doesn’t require nearly as much fuel/energy to get to from LEO. Thus, in space distance is not the key to determining how to get there, but the relative velocities of the different locations. The word locations being a loosely used term because each place is unique in description.
The thing that everyone knows about GEO is that it appears as a fixed point on the ground. The thing that most don’t know about GEO is that the sun shines all day long and twice as bright there. Its the perfect place for turning solar panels into renewable base-load electricity.
I present to you an updated Figure 10: “GEO – Earth’s Ring”
This website has been dormant for roughly 19 months. The current situation has led to a fortuitous turn of events that appears to be changing that. ‘We’, are currently looking for some help and have the ability to find that help. If things go right over the next several months this website should come back to life.
The New Moon coincided with New Years Eve this year. Not to worry though, there is a lot of new content up for the event. The book has been pruned through enough to be published in it’s entirety. In version .3 The figures all have placemarkers, obviously some parts of the book won’t make full sense until these figures are produced, but at least it’s out there now. Heck, I even put a teaser on the book page.
New Moon, New Year. 2014
China landed on the moon! That’s great news, and it’s the reason that I did not post anything on the last full moon. No it’s not because of the seasons shuffle. It’s not even because I haven’t had time to get anything done. Heck it’s not even from some technical difficulty.
The recent news that China landed a modern (and impressive) piece of hardware on the moon might be the most overlooked story of the year. It’s made me take pause to rethink how valuable this website really is. Remember the book is already written, I’m just combing through it slowly and making the figures. Time might not afford me this luxury anymore in the New Year.
At first, I thought that the Chinese moon landing was meant to coincide with the last full moon of 2013. This would be ridiculous because the Chinese new year is January 31st, and the landing happened a few days before the Full moon. In addition, the Chinese calendar is based on the moon, as opposed to the Julian calendar westerners use based on the sun/seasons.
I did consider taking part in the usual media frenzy that happens every time that news comes out, but decided that this would miss the point (much like missing the point of Christmas). Think about it for a bit, This website is named ‘colonize the moon’ and there is now a serious possibility of a Chinese colony on the moon. It’s not to shabby of a story, and it’s not lost on me.
Depth~ consider the backdrop of the surrounding world on this one bit of news. There are but a scant few days before it becomes the last real news of the year for western countries. So as the sun sets on the shortest day of the year, I think next year is going to be pretty good.
Good Things to come
Things have been going pretty well around here. So well that I decided not to skip the last full moon of 2013. Here is Figure 9 depicting that the delta-v on a return trip from the moon is actually less than the trip there. It is entirely possible to get from the moon to ground on earth with ‘zero’ delta-v. That is, if you have some sort of rail-gun magnetic launch system, and you use aerobraking.
I’ve been getting some questions recently and I might be making some changes to the FAQ soon. If you would like to contribute just lump your email into email@example.com. Or contact me any other way you choose.
Some feedback has indicated that I’m somehow ‘anti-mars’. This couldn’t be further from the truth. Without giving anything in the book away (before it’s publish-versioned) There will be a lot more on Mars later on, and a little on Jupiter (my personal destination).
This full moon there are lots of things up for publication. Firstly, Chapter 2 is now up on the book page. The teaser for chapter 3 was left in because I just felt like it. Now I must warn you that there is some controversial stuff in the chapter, but it’s really just lead-up for the plot.
Figure 8 is in a state of permanent hold because of certain rendering issues and I don’t care to solve the problem myself. I’m just going to wait until the software get’s updated and hope the issue goes away.
Since today is/was a double feature, I may hold off on the next publication of material until the next full moon (and skip the new moon on Dec 3rd). I don’t know what is going to happen over the next few weeks, so we’ll have to see.
I hope you enjoy the full moon tonight.
