There have been several delays due to wind speeds exceeding 25mph. The first delay was due to a sailboat within range of the launch site. Edit: New launch time set for 8:26 am. Orion transfer to internal power. Edit: LOX Fill drain valves didn't cycle to closed. Another hold. About an hour...

Decided we should have a thread for pre/post launch discussion of the orion capsule. Maybe we can talk about how much we hate wind, or maybe how much we dislike sailboats. Live stream is here: www.ustream.tv/nasahdtv Also a more active discussion over on reddit(sorted by new)...

Ah I see, this may be a useful resource then? https://www.easycalculation.com/physics/classical-physics/learn-gravitational-acceleration.php Distance would still need to be factored in somewhere though :\

Got this from from the Wikipedia page on gravitational acceleration, this might be what you're looking for. I don't think it shows the acceleration of gravity at specific altitudes but it does give a range."At different points on Earth, objects fall with an acceleration between 9.78 and 9.83...

Would it be useful for stuff like landing on a comet? Because as far as I know, it needs to be very precise and even the slightest change in velocity makes a huge difference.

I can't wait for the day that this actually happens. My family won't care but I sure will. What a time to be alive :)

So I just finished my chemistry homework and was going through my answers and googling them to learn more about them. I got to sodium fluoride and I already knew it was that stuff dentists put on your teeth and that it wasn't to good for you. I read that it has some advantages like preventing...

Saw this on reddit not too long ago. It's a very rare thing to see, especially on film. Really fascinating stuff.

Thanks, will do!

Thanks! I did some editing and IMO it looks a lot better.

Well today my mother got a pretty nice camera, she's been wanting one for a while and what better way to test it then getting some shots of the moon! This is the best photo she could get, the rest were very shaky and we're probably going to invest in a tripod. I also went out with my cheapy...

An elements reactivity is dependent on wether or not the electrons in it's outermost shell are filled to their maximum capacity. The alkali metals are the most reactive of all the groups. In this group, two elements react with oxygen(Sodium and Potassium). These two elements also react with...
