How many of those animals lived to enjoy a long and healthy life? Just sayin.

Anyone been following that we will landing on a comet in a few hours.....and can watch it live...

ummmm ....... did anyone check the parking brake?

Yeah, seems like those harpoons that were supposed to hold it down did not fire.

Very cool. This is equal to man landing on the moon in my opinion. Surprised so many people are clueless that this is even happening.

Even bigger potentially from a scientific point of view.

Since the very first human, we've asked where the fuck do we come from ? How the fuck did we get here ? Even way back in 500bc humans had the idea that maybe our origins are alot more interstellar than we generally perceive and thus came up with the idea of Panspermia.

Fast forward to 08 and while studying the Murchison metorite they discovered organic compounds such as RNA nucleobase, Uracil not from earth.

In 09 they confirm glycine in a comet, in 11 complex organic molecules in cosmic dust, in 12 glycolaldehyde in distant stars, 14 PAH's seemingly all over the place.

What this points to particularly when combined with the idea that liquid water was also transported here via comets and asteroids is that perhaps we are not as connected to the earth as once thought. Seemingly the building blocks of life are everywhere and they are constantly in the universal sense of that word being moved all over the fucking place.

Now that's interesting, that's an idea that will fundamentally alter our concept of who we are.

[Tuckerman]

The tweets that thing is sending from a comet is blowing my mind. Also did anyone hear the noise that comet makes?

Insane pictures are starting to come in.

What is really insane is that we are seeing something form the beginning of the universe 6,000 years ago. Just amazing.

Philae is facing trouble...
Where it intended to land...where it is...




Here's How Scientists Can Save Philae From Its Rough Comet Landing
The lander's triumphant landing on a comet wasn't as smooth as it first appeared. Philae landed in a bad location where it's hard to get precious sunlight, and the engineers behind the mission are trying to figure out what to do.

Here's How It Happened

When the Philae lander touched down on the comet yesterday afternoon, following a 7-hour flight from the Rosetta spacecraft, it faced two troubling issues. First, the lander's top-thruster was not functioning. That thruster was meant to provide a downward push upon impact to dampen the bouncy recoil of Philae's landing. Second, Philae's twin harpoons, which were supposed to anchor the robot to the low-gravity comet, failed to fire.

The combination of events meant that the lander ricocheted off the comet immediately after touchdown and soared upwards of half a mile off the surface. Thankfully, the weak pull of the comet's gravity was enough to bring Philae back down…almost two hours later.

Following two gentler bounces, the lander settled away from the target landing zone and with only two of its three feet on the ground and totally unanchored (it could even be on its side). Worse, Philae now sits in the shade of a giant cliff. The darkness is threatening to shut down the solar-powered robot, which has only 60 hours of battery life.

While the situation may seem bleak, it could be much worse: Philae was not flung entirely off the comet, and right now the minds at ESA are working on the best possible fix. These are their two immediate options.

Option 1: Shut Down and Wait for More Sunlight....
Option 2: Hop to a New Spot ASAP....

To add context escape velocity is around .5 m/sx2, if you know anything about delta v and spaceflight you realize what kind of margins they are operating with.

They have apparently discussed using the arm to give it a bump but it's entirely possible they would simply end up in a worse place, not like there is a book on what to do when your lander has issues on a comet.

The fuck? Copy the url, use [video] and[/video ] tags and done. yeesh. (take out the extra space in the second tag obviously)

[abraham]

Or copy the bit after v= and put it between [ YOUTUBE ][ / YOUTUBE ] tags

[TomCrac]

Where are you getting the [youtube] tags?... I'm more(on) of a simple copy/paster/clicker kind of guy.
