Bumping this for Dragon berthing attempt coming up at roughly 8:00AM EST/ 5:00AM PST. Here are links to the NASA TV stream and the SpaceX stream (which will start in ten minutes).

The Dragon just entered the keep out zone of the ISS (less than 250 meters).
Yep, successful capture by the Canada arm makes this the first private space venture to the ISS. I'm thrilled. After the defunding of NASA and the mothballing of the shuttles, I was kind of down about our prospects, but this is one hell of a pick me up. Watched it live.

Explanation: How much of Jupiter's moon Europa is made of water? A lot, actually. Based on the Galileo probe data acquired during its exploration of the Jovian system from 1995 to 2003, Europa possesses a deep, global ocean of liquid water beneath a layer of surface ice. The subsurface ocean plus ice layer could range from 80 to 170 kilometers in average depth. Adopting an estimate of 100 kilometers depth, if all the water on Europa were gathered into a ball it would have a radius of 877 kilometers. To scale, this intriguing illustration compares that hypothetical ball of all the water on Europa to the size of Europa itself (left) - and similarly to all the water on planet Earth. With a volume 2-3 times the volume of water in Earth's oceans, the global ocean on Europa holds out a tantalizing destination in the search for extraterrestrial life in our solar system.

This says to me that we NEED China to advance in the space race in a major way over the next 10-20 years.
They are the only country on the planet that can and will galvanize enough Americans to push Congress and a President to fund 10s of Billions of dollars per year in NASA. I'm rooting for China in a big way for the first time in my life.

you should be ashamed, that sequel was horrible. Quick edit out your post before more people discover this movie and have their memories ruined.
I actually enjoyed it, surprised I didn't know about it before I finally found out it existed on GAF.you should be ashamed, that sequel was horrible. Quick edit out your post before more people discover this movie and have their memories ruined.

You know what would be cool? If there was a bubble of water floating like that above a dry planet and it is released. I can't imagine how that would look.
I thought Jaws was going to be Close Encounters 2.I thought it was going to be Jaws in Space.
I've got an 8 inch orion reflector...but smart phone pic? Fuck that shit.
Strange thing to be be angry about?
Not everyone has a smart phone, quite many people still have normal cell phone with a camera... why wouldn't be that allowed in a contest?

Here we goooooooooo
The problem isn't the government (not really, no more than it ever is), it's that people in general don't care about going into space. Why spend public money when private enterprise something something pixie dust.I would like to think that this will get the US Government thinking about space again, but I know it won't. Good luck, rest of the world. It seems my hopes lie with you.
Object: Triton's subsurface ocean
Temperature: About -90 °C
A new day dawns on Triton. It's going to be a cold one, much like the last. And the one before that and every day since the moon settled into its present orbit around Neptune. Even the volcanoes here spew out cold gases and liquid water rather than hot magma. But below the frigid surface, which registers a temperature of -235 °C, there's something more clement: a liquid ocean.
At first glance, Triton seems to be just another icy moon a featureless, barren world spinning around Neptune, the outermost planet of our solar system. But Triton is different.
For one thing, it orbits Neptune backwards, moving in the opposite direction to Neptune's rotation. It's the only large moon in the solar system to do so. Satellites can't form in these "retrograde" orbits, so Triton must have begun life elsewhere before being captured by the gas giant. It looks a lot like Pluto, and probably came from the same place the inner edge of the Kuiper Belt, close to Neptune.
The Voyager 2 spacecraft flew past Triton in 1989, sending back images of the moon's frozen surface. They revealed signs of cryovolcanism the eruption of subsurface liquids which quickly freeze when exposed to the cold of the outer solar system. As such, Triton joins a short list of worlds in the solar system known to be geologically active.
Its surface ice is unique, too: largely composed of nitrogen, with some cantaloupe-textured terrain, and a polar cap of frozen methane.
But with a name like Triton the messenger of the big sea in Greek mythology this moon should really carry one more feature: is there an ocean hiding beneath its icy veneer? A new model suggests there could be. Understanding why requires a quick look at Triton's unique history.
We know that Triton was captured by Neptune. Such captured bodies start in highly elongated orbits, but as they interact with their associated planet, Triton-sized worlds are quickly dragged into more circular orbits. The process releases energy, which heats up the moon. The temperature rise would have melted not just the icy outer layers of Triton, but also its 1900-kilometre-wide core. Then it would have cooled to its current frigid state.
Earlier models had suggested an ocean exists on Triton, but they were quite simplistic. Saswata Hier-Majumder of the University of Maryland in College Park, and his student Jodi Gaeman, have now developed a more detailed model that considers both radioactive decay of core minerals and the orbital interactions that would have heated the moon.
Although heating from radioactive decay is orders of magnitude larger than heating from tidal effects, heat from the core alone could not keep the outer layer from freezing over the 4.5 billion-year life of the solar system, they say.
However, Hier-Majumder and Gaeman have found that even a small amount of heating from orbital forces makes a huge difference because it is applied to the base of the ice covering the subsurface ocean. "It puts a warm blanket on top of the cooling ocean," says Hier-Majumder. As long as the orbit is so circular that its 350,000-kilometre-radius varies by only a few kilometres, Triton should still have a substantial ocean beneath its icy surface.
That watery ocean contains a strong dose of ammonia, which keeps the liquid from freezing unless the temperature drops below about -90 °C. So, while it may be the outermost ocean in the solar system, it is not as cold as the -180 °C hydrocarbon lakes on Saturn's moon Titan.
We need to send orbiters to every planet, landing vehicles on every large moon!
I think there was even own thread for this video and indeed Neil came out bit douchey.Discussion about "Our Future In Space".
NdGT is acting like the biggest douche ever.
EDIT: forgot to say, the ending is remarkable.
I just found this interesting digital radio station that some of you might enjoy

"Historic Apollo mission audio mixed with ambient music."
I have it on as i'm playing mass effect 3, it's quite soothing

I'm happy for the success of SpaceX. Let's hope it gets things going.
