Chemistry equipment list?

Hello Fellow Instructablers!       Its been a while since I have made a post but I am back with a burning question!  I have a great interest in science and chemistry and always wanted to preform experiments seen on page of authors like Nurdrage for example. But I have never had the required equipment or chemicals to do these. I have taken a high school chemistry class and gotten my stuff down and now am prepared to take on the challenge of the lab. I have a birthday coming on on the 24th and my parents said if I wanted to get into chemistry I should ask for equipment and chemicals or what I need for my birthday.      So I will, but I need help. From an experienced chemist or someone who has done this before. Can anyone give me a list of basic-intermediate lab equipment that is needed for most experiments? I don't want to get one of those chemistry kits for kids since those are so restricted and only let you do the experiments given to you, not very fun So I want to get free use equipment and chemicals for any procedure. But I have no idea what is needed most or least and would really appreciate it if someone were able to do this for me. Just in the comments or PM, have a list of stuff I should ask for if I wanted to kick start my chemistry, what that item is used for, the price and its frequency of use to determine what I should decide on if there were to be a conflict. I would really appreciate any help I can get from you guys cause my birthday is coming up soon! Thanks everyone! ~Ostomesto

Create inexpensive hail pads - Citizen Science Contest

The SciStarter Citizen Science Contest is live! This is your opportunity to help millions of citizen scientists contribute to real scientific discovery. Make their experiences better by coming up with solutions to some real annoyances that hinder their participation. To get you started, here is a specific--and very real--challenge sent to us by project organizers. CREATE INEXPENSIVE HAIL PADS Background: The Community Collaborative Rain, Hail, and Snow Network (CoCoRaHS) volunteers take and submit measurements of rain, hail, and snow precipitation. These observations are made available for use by the National Weather Service, meteorologists, emergency managers, and others. The Problem:  Hail pads are essential to CoCoRaHS's mission to measure, map, and study hail. Each pad consists of a 12" by 12" square of Styrofoam covered in Heavy Duty Aluminum foil. However, in recent years, these materials have tripled in cost, which has greatly reduced the number of hail pads that can be produced and distributed. The Challenge: Create a cheaper hail pad that can measure the number, size, and orientation of hail stones. Enter now! Contest closes January 21, 2013

Could we host a contest on instructables? Re: DIY Science Lab Equipment

Hi, My name is Todd Duncombe and I’m a PhD Candidate at UC Berkeley and a member of the organization Tekla Labs  (teklalabs.org). Tekla Labs is student organization dedicated to making science more accessible by establishing a thorough catalog of Do-It-Yourself (DIY) instructions on the construction of laboratory equipment from cheap and readily available supplies. We are interested in hosting a competition for DIY lab equipment designs – as we have previously for 3D printed lab equipment designs  (http://www.teklalabs.org/print-my-lab-results/). We have currently raised upwards of $5k in prizes and are shooting for $15k. Tekla Labs is potentially interested in hosting the competition on either Instructables.com or using the Dozuki platform. I would love the opportunity to speak with an instructables representative (and hear the communities opinion!) about Tekla Labs hosting our competition on your website  – and the associated logistics. I look forward to you hearing from you! Todd Duncombe PS our organization was recently featured at the Clinton Global Initiative University symposium: http://www.youtube.com/watch?feature=player_embedded&v;=wTPJb8Z_WPw

process for anodizing aluminum with limited equipment?

Recently I have learned the basics of anodizing aluminum, and from what I understand the basic process is to clean of the aluminum bit to be anodized, stick it in a bath of a dilute solution of sulfuric acid, and do some electrolysis with the anodizing bit connected to the anode or positive of a supply, then pulling it out some time later and cleaning it off with soapy water and rinsing, and coloring the metal in a thin runny die, then wiping off excess and boiling the part. So first of all, do I need sulfuric acid? Any substitutes? Will HCL work, or a weak acid like vinegar or even salty water?  If the purpose of the sulfuric acid is to allow free ions to flow in the water, I do not see why it would not work. However, I am not a chemist, and my experimentation with electrolysis is limited to 6th grade science and dropping 9V batteries in salty water. (My favorite experiment was at home when using copper  and coins as the electrodes and watching blue-green corrosion develop and sink until the copper wire was made brittle and thin. Caused some AA rechargeable batteries to explode in the process though lol!) Also, will any die work? For really small parts, will it be possible to evenly die them with sharpie, standard paper markers, and/or highlighters? What dies will work well? Should the dies be water based, or based on some other thinner?

Help needed for english in a lab

I need some help with english in connection with scientific work in a lab and things like that. I am able to speak english nearly fluent in normal conversation but on special subjects i am lost. I am studying chemistry and a few days ago, when i had to talk to a lab assistant, who didn't speak german(my native language), I thought something like 'WTF is that thing called where you store volatile compounds and where you do the experiments etc.'. It would be nice, if you could tell me some words for common lab equipment and phrases that are essential in a chemistry lab, especialy for the case that something goes wrong. (well of course i also need a short explanation if the meaning isn't obvious) Thanks in advance.

What is the axial orientation of Polaris with respect to the Earth? Answered

So... I know the Earth's axis of rotation currently points (roughly) at Polaris, the North Star. (which, of course, is why we can navigate by it here on Terra Firma).  I also know that Polaris is about ~500 ly from us,  has a rotational period (hence an axis), that it's a transitional Cepheid (sp) (a star that varies between a larger, brighter state and a smaller, denser one) , that it has at least two l known, low-output companion stars, and that since the ~1940s it has undergone visible changes in its rotational period and its output. My excuse and reason  for asking... First, I did google it. Either no one has asked the question(doubtful), it can't really be determined with our present level of science (could be, idk), or I just didn't use the right search  terms to find the answer (the usual culprit ime) , but in any case, after an off and on search that's spanned the past ~year, I think it's time I ask. Secondly, the inspiration. I enjoy amateur astronomy.  However, time and equipment and location often limit my grand delusions for the next "Citizen challenges Hubble with stunning new photo of Zeta p3044-a!" award hahahaha.  But the real problem is most often because of my mid-level scope's somewhat limited ability (in comparison to a German equatorial mount) to track consistently and smoothly, and as a result, Polaris becomes an easy target when I get frustrated with the scopes performance on a given night (sometimes it does track brilliantly... for a stepper-driven alt-z, but only sometimes and even then only to the limits of the steps) because the only thing the scope has to track when pointed at the North Star is rotation, which it seems to handle better than both directions of movement (probably needs a new gear or the motor is wearing or my expectations are simply higher than that of my equipment ...). Of course, I also quite often choose to shoot Polaris when conditions are such that it's the only viable target (for instance, when I'm stuck imaging from my backyard, I have a postage stamp size hole that happens to point at Polaris... which of course basically "doesn't move", pretty much everything else is shrouded by century old, 8-100 ft tall forest during the warmer months, and when I can't drive out to a more suitable location, it's a lucky night when everything is "right", I can even align the mount (it uses a goto controller that requires a 3 star alignment for tracking with any accuracy). So Polaris is a no-brainer, (take some images for arts sake, fine tune the in-situ collimation, data-reduction test sets, etc.) . Either that or do something else...  Anyway, as a result of all of this, I'm found myself enjoying the simplicity of shooting the North Star and the area around it, and having fun with image processing and even optical train modifications to further the artistic side. And I've read a few articles about it's variability and the ~relatively significant changes in its behavior that have been occurring during the past 50 years that got me to thinking What I'm wondering is that when I image Polaris, am I looking at it "on its side?", "on axis?", or at some other viewing angle? Not that I'm going to be able to literally "view it on its side" or something, since optically imaging the star beyond that roughly of a point-source isn't practical, but just to know, since the darned question won't get out of my head. (been asking it for the past year quietly to myself and google. I hate to think how many cumulative hours I've spent at it...) thanks!

Modernist Cuisine: WANT!

Modernist Cuisine is finally going to be published on March 14! As a molecular biology major, chemistry minor, and general molecular gastronomy food geek, this is just about the coolest food book ever.  Of course it's pretty expensive ($625 list, $467 on Amazon), but compare this to the price of five high-level science or engineering textbooks.  It's in the same ballpark. I'd love to get my hands on this just for the excuse to break out the chemistry equipment! Check out the blog for recipes.

I have a question about how to organize what I have been doing for the past 8 months. . .

Many of you know I am, part time, mentoring and teaching science to a young lady with Asperger's syndrome.  Partly because I have so much fun with them, and partly from just forgetting, I tend to not use my camera nor camcorder much if at all.  Aside from that, I am NOT sure how to present/organize it all.   Each "session" contains between 5 and 30  different "experiments" some as simple as comparing a rubber ball rolling down an incline to a paper tube doing the same thing up to the making and use of lab equipment. The subject matter is diverse, from physics to chemistry to astronomy. I would appreciate any adive.   Thank you.

Oil Spill Water Cleanups As Fast As They Happen

We live and survive on oil today. That dependence won’t go away for at least a few more generations. Today’s technology allows us to drill oil just about anywhere in the world, and then move it to anywhere we want using behemoth water vessels. Unfortunately, there’s a dark side to all this and it happens when our technology fails us, as periodically demonstrated by mankind’s great oil spill disasters. The most recent being the Gulf Oil Spill of 2010. The amount of oil actually dumped upon our ecosphere and contaminating the environment was mind boggling. The numbing numbers are so large that we can’t even get our minds around it. And we all know that the responsible drilling company won’t fess up to how much was really spilled because even they don’t know, don’t want to know and furthermore want to forget about it. Is there some way to tackle this oil spill problem through the use of the very culprit that created it, namely technology? Of course there is, but it will cost the billions they used to clean up the mess they created in the first place.  We want to develop a technological process to be used worldwide that borrows from what we currently know, and clean up these oil spills almost as quickly as they happen upon our seascape. Did we finally clean up the Gulf oil spill?  Yes, maybe? But it took too long and we either didn’t use the right equipment or not enough prepared and available equipment to check the problem. Time is probably the most critical factor involved in mitigating oil spill disasters. While Nature obviously works to clean up ecological disasters, she takes perhaps a decade or more to make a region whole again. We need to help nature accelerate her time schedule to a few weeks not decades! Oil cleanup equipment exists that is too painstakingly slow and inefficient to get the job done quickly and effectively, and to recapture ~99% of the oil spilled. Today’s processes are makeshift, disjointed, and not organized nor designed to tackle today’s mega-proportion oil spill problems.  We need a cohesive mega-solution to handle mega-problem oil spills. A virtual army of specialists with proper equipment to attack, gather up and capture, then deliver the spilled oil to vessel staging platforms. These huge platforms will separate 99.9% of the captured oil/water, dumping the water back.  Oil tankers on standby then take this recaptured crude oil to refineries. This process must be set up with the proper equipment to dynamically proceed in real time. Only high sea states should be capable of halting its operation. The process of oil/water cleanup requires the serial use of various sequential operations where each performs a key stage of the operatic procedure. The orchestration starts with techniques that initially yield the biggest volumetric punch first, then refines this processing by using less volumetric cleaning ability but greater oil separation capability. All the while we have deployed an improved form of today’s containment apron, capable of hundreds of miles of coverage to prevent spreading the spilled oil slick to shore. Having researched today’s available oil spill removal systems, their usefulness has been categorized according to volumetric processing capability per time. Fast surface skimming techniques plus “huge”, constant flowing centrifugal separators clearly win, but are not 100% effective. Sponge-type, oil absorbent techniques then come to play as they are useful in nearly recapturing the remaining 0.1% oil from the water, but are slow and will be used solely on the remaining 99.99% pure water expelled from our centrifugal oil separators. Today we literally use these absorbers like sponges, dunking them into the oil slick, waiting awhile and pulling them out after they’ve absorbed some oil. Such prolonged processing times are unacceptable. Absorbers are to be used differently than today, their performance is vastly accelerated as they now act as 0.1% oil filters to process the pressurized water expelled from the centrifugal separators. The final residuals of perhaps 0.01% that the high pressure absorber filtration misses will require oil break down chemistry whose end products are environmentally friendly and allows Nature to restore balance. So the actual water dumped back will be better than 99.99% pure. Now let’s break this process down a bit and address the pieces of equipment involved. Our attack vessels are special, high speed catamarans that ferry cars between different ports today. They use water-jet propulsion, are extremely fast, maneuverable, and will be equipped with a special front-end water scoop to pick up the oil/water slick in real time while propelled forward. Their scoop or nozzle articulates, performing real time adjustments responding to oil slick depths thereby avoiding too much water pickup. Once their holding tanks are full, they reconnoiter with waiting intermediate-sized tankers to quickly dump their oil/water cargo. When these tankers are full, they deposit their load to one of the huge vessel platforms. These staging platforms use centrifugal systems to quickly and efficiently separate huge quantities of the oil and water, and dump the 99.9% cleaned water overboard (Nature effectively handles the remaining 0.1% of oil). When their tanks are full of oil, they start emptying themselves into the large standby oil tankers for delivery to refineries. QED. For you science fiction/fact fans, this concept requires enormous equipment, is on a huge scale and if viewed as one harmonious system may be the first Oil-Terra-Forming machine to be used on our planet.

What contests do YOU want?

I've seen a few complaints recently about contests - the "wrong" kind, or contests coming along just after they publish what would have been a killer entry. So, why not suggest the contests you would like to see? It doesn't necessarily have to be a contest you would enter, but maybe one that you think would have a decent response. I'll start: A hat contest.  Either making hats from scratch, or doing cool stuff to hats. A science contest.  Entries either make a piece of scientific equipment, demonstrate a scientific principle or process, or otherwise provide a learning experience. A walking stick contest.  I noticed that my mother's walking stick is hollow.  People must be able to come up with all sorts of things to make that empty space more useful or entertaining. A useless but bizarrely entertaining device contest.  Things in the vein of the Useless Machine and Rube Goldberg set-ups.  Entries must include how to make the device, and a video of it in action.  Judging would be based largely on entertainment value. A Time contest.  Anything related to time, timepieces or keeping time. A Scouting contest.  Entries that would fulfil the requirements of any badge of any part of the Scouting or Guide movement across the world.  (Extra credit for shots of entrants being awarded their badge?) A Guerilla Making contest.  Not making gorillas, but making something, then leaving it somewhere for strangers to find or encounter.  Include contact details for the entrant (or the site?) and see what happens. Volume Two contest.  Isn't it about time to start thinking about producing another book? Now, what do you want to see?

The Stair-Climber: My Idea for the Scholarship Contest

My name is Brian Smith and I am a recent graduate of Spring Valley High School in Columbia, South Carolina. I have done research in the field of robotics in the past for science competitions. I will be attending Georgia Tech beginning in the fall. What I would like to do with the iRobot Create is simply to extend the original functionality of the Roomba by allowing the robot to both scale and vacuum a carpeted staircase. From a functional perspective, ideally the robot would clean the first floor of a a two story house for some predetermined period of time, and then climb the stairs, cleaning them on ascent. The robot would then clean the second floor of the house for a predetermined period of time before descending the stairs once more to recharge and then begin the cycle again. As far as implementation is concerned, the first step of the cleaning process is quite straightforward; the robot will clean the first floor randomly using the same or similar algorithms as the Roomba. After the predetermined cleaning period for the first floor has elapsed, things get a bit more complicated. The robot will then seek out an infrared beacon marking the base of the staircase to begin ascending/cleaning the stairs. For this task, the mechanics of the system will be just as important as the software. Essentially, the robot must square itself with the first stair at which point it will deploy its equipped "stair rails" which creates a ramp which the robot can use to ascend the first stair. The robot then collects the rails, cleans the first step, and redeploys the rails to ascend the second step. This process continues for each step until the robot reaches the second floor of the house. The then robot resumes random cleaning of the second floor. By similar principles, the robot then descends the stairs and finds its recharging station on the first floor. Although I feel that this project will be challenging, I also feel that it is reasonably within my capabilities to be completed by the deadline.

How do I actually PROGRAM a z80, 8088, 8035, or their predecessors? (schematic, code, assemblers, UVeproms?)? Answered

I have a z80, apparently, with supporting ICs, on a PCB waiting to be salvaged. All I could find online for z80 programming was this guy who was making a whole computer out of it. And a lame "z80 world" site that doesn't help me. Also, on a separate board, I have a couple of Toshiba TMP8035P (with UVeprom nearby), whose online "datasheet" says that it's instruction set and pin compatible with the intel 8048.see:http://www.atarihq.com/danb/files/8048.txtand:http://download.theicstock.com/TMP/359/TMP8035P_1541359.pdfI have programmed microcontrollers before, so I know a tiny bit of what is needed for programming them. (Note: modern microcontrollers, in basic-esque languages, notably picaxes and basic stamps)My problem is in how to actually make the program on my computer, press the download button, and the chip run the program. I have no idea how to do assembly, (or find the right assembler). I am also clueless as to hook the computer up to the chip. (I suspect it requires a parallel port, but I think I only have DB9-pin serial easily available. I do have a single parallel port in a win98 computer, but it would be a pain in the butt.)In addition, I don't have a UVeprom eraser light. (I have an uncle who does, but I only meet him every now and then. Maybe he would let me borrow it?)Another problem is, I'm on a time limit. It does not have to be done tommorrow, but if I do not clear the garage of my currently un-programmable outdated microcontrollers soon, I will be too busy with college this fall of 2009 to work on those things, and my parents will force me to throw them away.As for the 8035's my uncle also needs room in his garage, and if I can't program mine soon, then he will throw away his remaining stash of them. (No sense in holding on to equipment your nephew can't program in a timely fashion)By the way, the same uncle dumped a CMX controller on me, with a weird keyboard, huge scroll wheel mouse, and the big box with computer-like guts inside, and a gazillion I/O ports on the back. He said it could be programmed, but Wikipedia said the company that made this video-editing machine went bankrupt or something. If I had the "instruction set", I assume assembly, in addition to a download circuit, then I can use this thing for controlling lots of cool things.Oh, and my uncle is very nice to me, so don't think I don't like him just because his hobby is dumping old junk on me.PS: I'm just whining, but it seems all these old microcontrollers, equipment and whatnot assume I grew up with these. I didn't, so anything beyond plugging in a basic program to a picaxe is rocket science to me. (No, I'm not Russian)

UK Charity needs the help of Makers

I visited the Grand Henham Steam Rally today, and came across a stall with a clearly hand-made sign with individual letters moving back and forth on small cams.It was manned by a couple of chaps from the local "panel" of Remap.Remap is a very special charity, working through a nationwide network of dedicated volunteers. These inspiring people use their ingenuity and skills to help people with disabilities to achieve much-desired independence in some aspect of their lives, or to enjoy leisure opportunities previously closed to them.Remap's unique pieces of special equipment are tailor-made by volunteer experts and given free to the people who need them. Because, as well as being inventive and skilful, they also care about people in their local communities who have disabilities - even a combination of them - which mainstream services have not been able to counteract. Our volunteers think these people matter a great deal - enough to give their time and energies for free, taking the trouble to ensure that each item they make really suits the individual person concerned and does the job it is meant to do.Remap already has 85 panels across England, Wales and northern Ireland, and helps over 3000 people with disabilities each year. With your help this number can be greatly increased.The chaps I talked to said that Remap was "just a name", but they reckoned it stands for Real Engineers Make Anything Possible.The things they make are not rocket science, or even very complex. They are just sensible solutions for people who have unique needs. Like making a toilet seat with a smaller hole for a child lacking in the motor skills to balance on a narrow seat. Or adding extensions to tap-handles for arthritic pensioners. Or making custom hooks so that a woman who suffered a stroke could reach to close her windows. Or even just adding short extensions to the arms of a chair so that the user can get enough leverage to stand.They are a nation-wide charity, and need help everywhere. You can find a local panel or contact them centrally.If other areas are like my local panel, they especially need younger volunteers. The youngest member of the local panel here is in his early sixties, and they recently buried their (ex) oldest member, still Making at 84.RemapCase studiesHow to volunteerFind your local panelRemap in Scotland

You can help save a rare frog from extinction!

First off, I realize instructables does not want pure advertising on their site through these forms. The voting is optional and I don't want this to be viewed as advertisement. If nothing else, I want to share with you our story in the project, and hopefully you'll see how awesome this is. We are doing something that no high school has ever achieved before, and I think it's more relevant to the site than some re-posting of a blog article. I hope that you take a few minutes and find out what the Frog Project is all about! Want to support the cause of helping endangered species, education, and advancing biotech in schools? Well, take 5 minutes and vote for our school to convince Khols' to give us 1/2 million $$! Unfortunately the contest is over, but we're going to go for a $250,000 grant for a Pepsi contest in November. If you become a fan of our page (noted below) you'll be updated. Check back in November! https://www.facebook.com/pages/The-AAEC-Frog-Project/128763967175416 ======================================================== Not convinced? Well, here's our story: You can help save a rare frog from extinction, and it is free! Kohls the dept. store is donating $500,000 to the 20 schools with the most creative need for the money. Your vote can help our school win this money, and best of all it costs you nothing! We are working on a project to try and save a rare frog from extinction. And we need the cash. At our small high school of 300 students, we are trying to completely sequence the genome of a rare Arizona frog. We hope to accomplish 2 things from this work. 1) We hope to rescue this frog from extinction. 2) We hope to train a new generation of students in modern biotechnology, and rescue the State of Arizona from last place in quality of education in the United States. The Chiricahua Leopard frog is currently listed as a threatened species. We have been working in conjunction with the Phoenix Zoo and Arizona Game and Fish to develop a genetic test that could aid in conservation efforts. We have already spent a year working on the sequence of the mitochondrial chromosome of this frog. Our school actually owns a DNA sequencer. We have made pioneering efforts in the design of genetic tests for this frog. Our students have presented 5 posters on our work at the International Plant and Animal Genome conference (PAG), quite an achievement for a high school. Our project was recently awarded one of only three heritage grants: http://www.gf.state.az.us/w_c/heritage_projects.shtml By the way, the other two Heritage grants were awarded to Arizona State University and Northern Arizona University. What we really wish to do is completely sequence every chromosome in this frog. This is a very ambitious project. Consider that the human genome project completed in 2003, cost $3 billion dollars and took 13 years. Our leopard frog is estimated to contain twice as much DNA as humans! However, we think that with appropriate funding, and new technology that has recently become available we can accomplish this task in 2 years! We wish to construct what are called “DNA libraries”, collections of broken chromosome fragments of known sizes. These can be sequenced quickly using NEXT generation sequencing technology. The Chinese genomic group BGI has agreed to cover the costs of NEXT generation sequencing, and genome assembly for our project (an estimated $1 million) if our school can come up with the remaining funds needed for the construction of the libraries. We need to purchase about $200,000 in new equipment, and extend our existing lab space. With the completed genome sequence, we would like to have a custom “gene chip” manufactured. This chip will have all the DNA of the frog physically printed on it. The chip allows experiments to be carried out without any harm to any frog. This chip could then be used to aid conservation efforts by the Phoenix Zoo and Arizona Game & Fish. It could allow the exact parentage of every Chiricahua frog that is discovered to be known. Eventually this technology will become the backbone of conservation work on all species, but at this early stage it is not possible for Arizona Game & Fish to raise the funds needed to generate a gene chip before it is too late for the frog. Our school hopes to be the first in history to carry out a genome project. We hope this will serve as a guiding light to other schools, and start a grass-roots movement in the conservation and education world. Help us save our frog! Here is the catch. Vote for us on Facebook, and convince all your friends to do the same (forward this message to them), or unfortunately the frog bites it! Everybody can vote up to 5 times for us. In this way YOU can help make the difference not only for this rare species, but if we can succeed you will help pave the way to help many others. https://apps.facebook.com/KohlsCares/school/32741/aaec-paradise-valley Regards, -Mike Dr. Mike Brown Science Dept.

Ancient technologies revisted - The space race

Back in the glory days of science we had the US, China and Russia competing and getting "out there" first.After WW2 finally ended we had the time and money to waste on humanity greatest challenge - getting a man safely onto the moon and back.The German space program had the advantage of a head start but Russia was not far behind.To show the world they mean business we got Sputnik.A tiny aluminium ball with a crappy battery emitting a "beep" from orbit.Nothing to be proud of if you actually think about it.However, it was a huge deal back then and a blow to the western world.The communists were faster...China was more modest and well, less successful at that time but it did not stop them.With Russia already announcing to get some animals up ther next the mighty US had to take a few shortcuts.It was no longer a race to get a human up there safely, it was only a race to somehow managed to get a man on the moon and back.The calculator your kid uses at school is more powerful than the "compters" used in the carfts for the Apollo program.Back then though it was top notch tech and deemed reliable....We already knew about the Van Allen belt and its deadly radiation levels.So you would think someone would have included this danger into the design...Assumption made in...It was assumed that the limited exposure time and some rudimentary "shielding" would be sufficient to protec the astronaut.Thankfully most of these assumtions turned out to be correct AFTER men made it through there in their tin cans.The step to send up a rocket with fancy equippment to do proper measurements and collect data about required shield material was simply skipped.A few weather balloon were tried though...Long story short, the race was over when the world listened to the famous words "A smal step for a man,but a giant leap for mankind."Russia continued for a while but losing the race meant those in charge decided it is no longer worth wasting money on.Shortly after the collapse followed in Russia.Why would the Russians give up so easy and why did China seemingly pull out of the race as well?Despite being "enemies" the old claim and goal was still valid - or was it?There was always that dream to go further out there once we made it to the moon.Build habitats on the moon so we can build ships and mine ressources.And for a while this dream was kept alive by the US.We went up there a few times, got complacent and even the public in theend failed to get hooked on the TV screen.Going to the moon and making it back alive was turning into a routine, nothing special anymore.Not even moon rocks could revive the public interest.It was costly as well....Officially the moon program ended for a long list of plausible reasons.What is striking though is that it ended rather aprupt and without warning so to say.We had rockets fully assembled, waiting to be used, we had space capsules and long lists of experiments tobe performed, we even included fancy equipment like a soloar powered transmitter supposed to constantly send seismic data and more back to earth.All this stuff never god used, was disamantled, deemed to be too expensive.Hold on a second here now....First millions are wasted to build a fancy rocket, more money is wasted to build new space capsules and landing equipment and then even more money is wasted on stff to get up there.It is then only logical to pull the plug without using any of it.....NASA abandoned projects before, including fully functional machines but they never wasted them like this.Some theorists claim the race to the moon was not about exploring the moon for our use once we actually made it up there.Their claim is that we found things that scared the US enough to never go up there again.These theorists got laughed at for decades, yes decades as their claims based on isider info are as old as the space race itself.Occupation is a word that you can use in many ways.Like occupying a land that you don't own but declare it yours anyways bacuase you are more powerful, more advanced than those you found on "your new land".Or like in deviding territories on a continent declared to be owned by no one - the Antartis.Officially this icy continent is free for everyone and every nation - the truth is far from it though.Same is true for our moon.It is devided and subdived to cater for eveyone making a claim.And to make a claim is simple; You go up there and leave something behind, then you state how much of the area you declare your so you can occupy and use it.Funny thing is that like in Antartica every is very strict and stays far away from the other fractions....The race is on again!!!For some it was a sudden announcement when we got to hear the US is planning and financing moon missions again.For others though it was a very predictable move.More and more private companies reach the point where they can afford to send someone to the moon at their cost without the need for taxpayer money.Commercial space flight is said to only be a few years away, mabe even sooner if SpaceX continues as planned.And "right on time" picures and videos are officially released by NASA to actually make it very plausible and almost undeniable that something or someone else it already out there.Including videos that seem to show creature living in the dead vacuum of space.But why not just relax and sit back like they did with commercial space flight?Give someone a few million and technical guidance but don't waste real money on it...Well, you can't really enforce to stay in control of everything, especially when it comes to the moon, if it is not your program.Once the testing is done your pilots are out, your crews are out and a private company is in control...So what is it on the moon the US is so desperate to get first hand experience on?The first few moon missions were mostly a prove of concept, later NASA used rovers to explore the areas around the landing sites, installed mirros to perform laser measurements from earth...The took sample, drilled into the ground and every now and then saw flying objects flying past, watching them.Like the Foo Fighters during WW2 they were like small spheres and extremely quick.Nothing to worry though as NASA knew about them for a long time, harmless little things....The story got a twist when the landing site for one mission had to abandoned.The astronaut appearently reported they were being "bullied" by Foo fighters and will try to land on the beta landing coordinates.It was enough to justify to check if there might e someone or something on the moon already.After all it could be unwise to do the same as what was done when Amrica was "found" by Columbus...And so some sesmic equippment was transported up there.Orginal intent was get seismic data from small metorites hitting the moon to determin the risk factor.Dropping the launch stage back onto the moon was meant as a test for the equipment and it dropped relatively close to the seismograph.What was observed came as a shock to those analysing the data - the damn thing is faulty!So during the next mission the data was checked again, with the same result.But it was also finally confirmed the results are correct as a second device gave the exact same seismic readings.What happened??Whenever something big and heavy dropped back onto the moon it started ringing like a bell for hours....And although never openly admitted, these finding actually pulled the plug on the moon program.Unofficially and if you trust the clue we got from former astronauts the bullying intensified with every mission.Some went as far as saying they did not feel welcome up there - go figure...NASA first tried to just cover it all up.A few years later they got more serious and tried to come up with plasusible explanations once it was claer evidence from these seismic reading somehow leaked out into the public.We got presented everything from the moon being made from some granite like and very hard rock.Nicely explains the ringing but not why it is did not crumble to dust from all the meteorites hitting it.We also got the explanation that the moon only has a very tough outer shell, possibly formed by the impact of the meteorites.And the list went on and on...Finally some outsiders took a decent look on the data, did good calculations and computer simulations basd on the fact that the moon for whatever reasson has no rotation as it should have.Their findings clearly state the moon is a mostly hollow sphere with much more mass on the side facing us.Based on the frequency and amplitude recrded during these events the sphere HAS TO BE made out of some high strenght metal.NASA made it a priority to ridicule this theory and over the years more and more reputable scientists jumped in as well.No matter what though they all failed to provide real evidence that the hollow moon theory is flawed - the data just speaks the truth.At least it was accomplished that the theory was forgotten and everyone could move on.Until more NASA evidence was leaked to outsiders.During one mission it was attempted to drill into the center of a crater and the results were the same as claimed during probe explorations done recently by china - first a thin layer of compressed rock, then metal, then nothing....Today you will find hollow moon data on official NASA servers available to everyone....And it all became available to be found right after it was declared "We are going back up there again!"The thing the press overlloked when this statement was made was what followed after "We have to"....Just think about it for while....NASA delevoped all sorts of prototypes and wasted billions to create fancy space crafts and drive systems.But start the next race to the moon once more with old and conventional rockets....Not because we are unable to come up with alternative lauch methods, we already developed them and computer simulations show us they would work perfectly at a fraction of the costs for a big rocket.Not because there wouldn't be money for alternatives either.Only because we suddenly no longer have the time to build and ready the alternatives ;)Almost 80 years with no interest, no funding, no plans.Then, within less then 3 months of work and decision making the race is on and more important than ever - WHY???We wanted to be able to fly like the birds since the dawn of time.We did it eventually.We wanted to fly faster and higher and we again did just that.We never stopped, we alway came up with new ways to make us fly and do safer than ever before.We did the same for the space race for a short while only.We settled for having a fancy space station close to home instead...Our urge to reach the stars is coded into our genes, we just need to somehow get closer and closer to them.But every time we get close to fullfilling this dream we pull the plug.If we can build and maintain a space station in orbit how hard would it be to assemble a space craft in orbit?According to those who planned and often protyped theise toys no big deal at all as it was already integrated into the design.We could have a little fleet of crafts up there already using the space stion as a "home base" when required and fueling up from the rich Helium3 deposites the moon is claimed to have.We did not do any of it, we entirely stopped the concept, the planning - again I aks you why....Once you figured out what really is so important about our moon you know why the space race seems to have stopped with the end of the Apollo program. You also figure out why we now have to go back up there.What you won't find out (yet) is what is really up there and how it got there.
