[Some kinds might work better that others.] (2) Divide the sample into two groups of equal weight and number. (3) Sprout one group in distilled water on filter paper for three or four weeks. (4) Separately incinerate both groups. (5) Weigh the residue from each group. [The residue of the sprouted group will usually weigh at least SEVERAL PERCENT MORE than the other group.] (6) Analyze quantitatively the residue of each group for mineral content. [Some of the mineral atoms of the sprouted group have been TRANSMUTED into heavier mineral elements by FUSING with atoms of oxygen, hydrogen, carbon, nitrogen, etc..] BIOLOGICAL TRANSMUTATIONS occur ROUTINELY, even in our own bodies. Ingesting a source of organic silicon (silicon with carbon, such as "horsetail" extract, or radishes) can SPEED HEALING OF BROKEN BONES via the reaction Si + C --> Ca, (much faster than by merely ingesting the calcium directly). Some MINERAL DEPOSITS in the ground are formed by micro- organisms FUSING together atoms of silicon, carbon, nitrogen, oxygen, hydrogen, etc.. The two reactions Si + C <--> Ca, by micro-organisms, cause "STONE SICKNESS" in statues, building bricks, etc.. The reaction N2 --> CO, catalysed by very hot iron, creates a CARBON-MONOXIDE POISON HAZARD for welder operators and people near woodstoves (even properly sealed ones). Some bacteria can even NEUTRALIZE RADIOACTIVITY! ALL OF THESE THINGS AND MORE HAPPEN, IN SPITE OF the currently accepted "laws" of physics, (including the law which says that atomic fusion requires EXTREMELY HIGH temperatures and pressures.)

From what I understand from Dr. Frank Six of the Marshall Space Flight Center there is no insrmountable problem in bringing HST back. IT was designed that way to begin with. Also it is my understanding that the solar arrays WILL be one of the items replaced on this mission. The originals were built by Brit Aerospace and I think the new ones are too. I am currently working with the guys at MSFC that are in charge is the HST power system, although I have not spoken with them in a long time about HST.

Some wonder whether or not the moon could have ever supported an atmosphere. I'd be interested in knowing what our geology/environmental sciences friends think. As for human tolerances, the best example of human endurance in terms of altitude (i.e. low atmospheric pressure and lower oxygen partial pressure) is in my opinion to the scaling of Mt. Everest without oxygen assistance. This was accomplished by a team of mountaineers who trained at high altitudes for quite awhile (I think a few months) and then were flown by helicopter from that training altitude to the equivalent altitude on Mount Everest, where they began the ascent of our planet's highest peak without oxygen tanks. This is quite a feat of physiological endurance, because if you or I tried to go to 20,000 feet and exert ourselves, we would probably pass out, get altitude sick, and could even die from cerebral edema. So this is the limit of low pressure. High pressure situations would be limited by the duration of time which it takes to slowly acclimate to a higher pressure. Skin divers would know alot about high pressure situations and could tell you about how they safely make deep dives without getting the bends. Some military experiments have put people under several atmospheres of pressure (not sure what the high limit was because the papers aren't in front of me). Usually at a certain point, the nitrogen in the air becomes toxic to the body and you start acting idiotic. Divers call this nitrogen narcosis. Those afflicted can do very dangerous and irrational things, like taking off a diving mask and oxygen tank in order to talk to fish at 100 feet under water. (Hope any diving folk can elaborate on this matter, as I am not a diving expert). Mars cannot support human life without pressurization because the atmosphere is too thin (1/100 th our Earth's atmospheric density). In addition, the Mars atmosphere is mostly carbon dioxide. Basically, you would need a pressure suit there, or you'd die from the low pressure.

Why is the general public going to be interested in the technical details of long term space habitation? I like the idea of the study, but it should be released to other scientists and engineers who will be able to use it. If you want a general public document, you'll need a more general publication. >I believe that if any long-term space exploration program is to >succeed we need to basically learn how to engineer our own microworld >(i.e. the spacecraft). Only through the careful analyses of engineering, >chemical, biological, and medical factors will a good ecosystem be created >to facilitate human life on a long-duration flight. As one working on Controlled Ecological Life Support Systems, engineering the microworld isn't the problem. The problem is understanding the basic chemical, biological and medical factors to be able to engineer them efficiently. For example, the only way we know how to produce food is from plants and animals. Food synthesis is not very far advanced. So we have to orbit a farm. Well that's obviously not very efficient, so we use technology to reduce the mass and grow plants hydroponically instead of using dirt. This is where the engineering comes in. But new technologies bring new basic questions that we don't have the answers to. Like, in dirt we can grow tomatoes and lettuce right beside each other, but in hydroponics it turns out that you can't do that. The lettuce growth is stunted when it's grown in the same hydroponic solution as tomatoes. So now you have to consider what other plants are going to have similar interactions. This means some basic applied scientific research. And that's what needs to be done with all technologies that have been developed so far. We also need to find out how they interact together. That's where we are now. >So, I would like to see posts of opinions regarding the most objective >methods to analyze the accepted scientific literature for technologies >which can be applied to long-duration spaceflight. First you need to do the literature search. There is a lot of information out there. Maybe we should just pick a specific area of long term habitation. This could be useful, especially if we make it available on the net. Then we can look at methods of analyzing the technologies. >Such a detailed >literature search would be of interest to ourselves as space advocates >and clearly important to existing space programs. >In essence, we would be dividing the space life science issues into >various technical problems which could be solved with various technologies. >This database of acceptable solutions to various problems could form the >basis of detailed discussions involving people from the bionet, isunet, >and any other source! Unless there is an unbelievable outpouring of interest on this on the net, I think we should develop a detailed data base of the literature search first. Then if we accomplish that we can go on to real analysis. The data base itself could be useful for future engineers. That's my response Ken, what do you think?
