Getting close! almost 8 years later and I see the faint glow of the light at the end of the tunnel! Rocket engine is finally stable! I havent had a catastrophic failure for over a year now. However there have been several premature shut-downs. Luckily I have been able to track them down and...

I want to say thank you to everyone here. Over these past few years its been a great journey and one that continues. My endeavor to understand has hit 3 milestones and without you guys I would have never been able to wrap my head around some of the concepts that many of you may laugh at thinking...

So Elon Musk Makes a statement about using Nukes on the poles to change the ice into atmosphere on Mars. I know... Links... http://www.iflscience.com/space/elon-musk-says-we-could-terraform-mars-dropping-thermonuclear-bombs-it So I by my logic I am an idiot. In a nutshell: I stated the reason...

I want to build a few different desktop or shelf size, cool looking Physics demonstrations. I am posting this to farm ideas... Cloud Chamber - I have a Peltier cooler. But i would need to find a suitable energetic sample to make it work well I suppose. I am not sure if its a good idea or not...

I admit, I am very, very late to the party... I just watched it for the first time about 2 or 3 nights ago and since then I have been thinking a lot about it. It was a great sci-fi movie if you did not remain grounded in reality while watching it. It hits some spots like 2001/2010 did.. On human...

I came across this little story while listening to a recording of a female cosmonaut who sounds very distressed. The cosmonaut is a story of its own and one I suspect we will never know the truth. But the idea was some cats over in Italy back in the mid 50's constructed a extraordinary HAM radio...

Its been a little while since I raided the forums here so I figured I might make a stop by. :) I just finished reading an article by space dot com on ghost galaxies. Approximately 4bn years ago a few galaxies were ripped apart and some of the stars are apparently wondering around the area...

https://www.youtube.com/watch?v=DQ2hOH23-zU I have the parts in my lab to construct one of these. Although I would have to turn a nozzle on my lathe, but I think I can make it. Does anyone know much about these engines? The skeptic that resides in my brain says thrust to weight is a big...

SNOOOOOPY COME HOME! Makes me think of that song from the snoopy come home movie. Anyways, I was reading about how the lunar module is still in heliocentric orbit and has been since 1969. I wonder, if you could travel out to it and go inside what it would look like today. Would you see an...

https://www.youtube.com/watch?v=CF_hRKqFicQ This got me thinking a little bit. I remember listening to how they mitigate this from their gym equipment for example. Its kinda cool, yet scary to see this i think if I were there. Regardless, I have some questions to ask. I know how to use...

When you look up at the night sky, what do you feel? Is it just the same sky you have seen all your life or does it represent something else? The universe, our place in it. How we got here, perhaps why we are here... Is there a purpose? Are we really destin to become space fairing or are we...

http://www.space.com/8293-universe-born-black-hole-theory.html I randomly thought about this a few weeks ago while outside with my telescope looking at the stars. Tonight I decided to ignore the ones saying this is complete conspiracy theory material and gave it a lookup. It seems... So...

It looks pretty straight forward up until they talk about "proprietary Refrigerant" ... I was hoping somebody could chime in? If I could actually make small amounts of LOX this is would be most helpful to me in designing a real engine to actually achieve my dream. Im sorry, solid rockets, KNO...

I was a total flunky in highschool. Ended up dropping out and getting a GED. Between living on the my own at the age of 16 and dealing with life problems I just could juggle school and my learning issues. I crumbled and failed like no other. The one subject... Space was something no matter...

I am curious to see what astronomy/physics type questions you ask yourself and think about when you go to bed or are sitting thinking late at night.. To start I will name a few that constantly reel through my mind. Serious questions; 1) Why are we here. Is there a purpose for us? 2) When we...

I was wondering if some of you might be able to give me some tips when flying in FSX. I've been working with it for 2 years now and although I can do alot, there are still things I cant do well. Basic things... 1) Staying on a glide slope. Depending on what im using whether it be ILS to guide...

That feeling when you think you have 11 lbs of fuel left in your wing tanks... Just enough to get you to the runway... Only to find out, some how this 11lbs means you are completely empty and your engines flame out. That feeling when you thought that 11 lbs in each tank would be just enough to...

Hello! So Im just going to post some thoughts in a really unorganized way... Perhaps this will stimulate some conversation and I will walk away from this learning something new. Ok, after thinking, then reading about this method.. Why the heck are we not doing this? Without attempting to...

On my facebook page I have liked a certain page that I cant name due to the use of vulgarity in its name. Its something like this... "I <blanking> love science". They made a post today that has really sparked my interest. Here is a link to the Science article talking about it...

Ok, I have to use orbiter 2010. The addons I want to use namely AMSO my favorite will not playball with the beta. I presume other addons wont either which is why I decided to stick with what works. I ventured over to Dan steph's page and he has repackaged the compatible Ummu etc and...
