If you are interested in Homotopy. An Old Conjecture Falls, Making Spheres a Lot More Complicated Honestly worth a read. Mathematical topology marches on.

Whenever I do a software update I have a little fear in my gut that it might not work and I'll be left with a bricked system. And then there's this: NASA's Curiosity Mars Rover Gets a Major Software Upgrade

I'm a big fan of the idea of in situ resource utilization in space. The more we can take advantages of resources in space, the less we need to launch from earth. So this seems pretty cool to me...

Whatever you think of Elon and his antics, this should be good. It's either going to be a stunning example of how to belly-flop an enormous rocket flip it and land it on its backside or it's going to be an epic RUD. I think it may be happening tomorrow...

FYI: Lots of space stuff detected in very clever ways. :) (they did pretty much know it was there...just could not prove it!) From an article in NewScientist:

Russia's M-27M spacecraft, on a mission to resupply the ISS, is out of control and apparently heading for a fiery death as it tumbles towards Earth. :( Track it here: http://www.n2yo.com/satellite/?s=40619 Live updates from The Guardian here...

ISS suffers cooling loop shut down I assume that since the cooling loop is on the Big 14 of expected operating issues, the pump or pump component has a spare in orbit or at least one waiting on the ground.

Couldnt find a place to put this. Saw this linked on Cluesforum,(it's fake obvs ;) )wanted someone with intelligence to explain the odd TV vs Live picture delay as it's bugging me. All seems to be out of sync with each other. http://www.youtube.com/watch?v=D-f3wXAnjgE

An add for a telescope seen on Ebay http://www.ebay.com/itm/Celestron-C6N-reflector-optical-tube-/200731262697?pt=US_Telescopes&hash=item2ebc83fee9 Unbelievable! You've had me since I left the factory. A couple of years ago, I was the only thing you could think of. You couldn't wait for it to...

A simple science question that occured to me Would it be possible to travel through empty space by continually changing your shape? E.g. Would an amoeba have the ability to freely move within a weightless environment?

Well done and very informative: http://www.space.com/10900-solar-system-planets-scale-infographic.html

I remember seeing a show as a kid during the '80s or '90s. It was mostly set on spacecraft, although it started out on a very polluted (and rainy) Earth. I can't clearly remember much about the show except for an episode where a guy made a mass driver out of spare parts that shot like a cannon...

http://www.abc.net.au/news/newsitems/200604/s1607840.htm I always thought that alcohol was a by product of biological processes. Is this interstellar alcohol a by product of living things in space? Could this be proof of extraterrestrial organisms? This is a legitimate question although I...

Newfound Planet Orbits Backward

So the universe is expanding. Space is still expanding as a result of the Big Bang and it is slowly being being accelerated apart by something currently termed Dark Energy. As a layperson with only rudimentary basic college physics, I have no real idea what "space" really is. What is it? A...

"FDC 9/5902 FDC .. SPECIAL NOTICE .. EFFECTIVE IMMEDIATELY UNTIL FURTHER NOTICE. AIRCRAFT ARE ADVISED THAT A POTENTIAL HAZARD MAY OCCUR DUE TO REENTRY OF SATELLITE DEBRIS INTO THE EARTHS ATMOSPHERE. FURTHER NOTAMS WILL BE ISSUED IF MORE INFORMATION BECOMES AVAILABLE. IN THE INTEREST OF FLIGHT...

Came across this on another board - the Space Fountain. Had a read of it, but it doesn't feel right. I don't know enough physics to work it out, but it looks to me like it would be fine until you tried to use it to lift something, at which point the energy costs would increase dramatically...

I know next to nothing about astronomy, although everything I read about it is extremely fascinating. My question concerns the absolutely incredible pictures of planets, stars, galaxies, etc. that I've seen throughout my life in various books, internet sites, tv programs and the like. I have...

Ok, I have a question about electromagnetic radiation traveling across space. I am not a physicist and my knowledge of mathematics is limited to basic calculus. I am also not a cosmologist, so this may be a fairly common question, and if so, I am just ignorant of the answer. Here is the...

Here are some recent space shuttle images. These are great! They are fairly high resolution so you can zoom in and examine all the gadgets and stuff.

If the universe in ever expanding and infinite, how can something be halfway across it? Is it just sloppy writing and editing?

I was going to post this in the science section but figured there'd be little point. Iran unveils space center, launches rocket Hey! Get your own name(s)! Copycats.

I'm not sure if this was posted before; if so, my apologies. Seems a man called Arthur Blessitt carried a full-sized cross literally around the world, and now wants to send a smaller one into space. Why? Well, in his own words from the site: "The cross will be over You personally! The Cross...

For the wide-eyed futurist, the costs of slinging things into space is one of the least promising things about space. Depending on how you decide to work out the numbers, launch costs typically work out to the tens of thousands of dollars per kilogram. There is the question of whether there's...

Was thinking about that wonderful scene in 2001 when Dave Bowman blasts himself into an airlock with no helmet on. Then I started thinking... if you go from say normal atmospheric pressure, to vacuum, to normal atmospheric pressure again, even in a short space of time like 10 seconds, wouldn't...

Don't get too excited. It's just a cockroach that the Russians bred in orbit. http://www.foxnews.com/story/0,2933,304744,00.html

Hey gang, this is a follow-up from a sci-tech thread. To what degree should government be involved in spaceflight? The poll options don't reflect the full complexities of these issues, so feel free to discuss distinctions like engineering research vs. other research. Let the feud begin...

This is interesting.

So I read an article the other day that astronomers have looked 13.2 billion years back in time basically, or roughly 500 million years before the supposed big bang. So if the big bang actually happened, could astronomers finally prove it by looking back that extra 500 million years? Would...
