Alright alright alright Philae Comet Landing

[HomerJS]

Meanwhile the Republican response...

I'm not a scientist but this entire project is a hoax. Only arrogance says we can't have a different opinion.

Please do us all a favor and leave the political remarks in P&N.

Compared to airliner for scale:

They should have just landed the airliner on it when they had the chance, instead of dicking around with a probe.

Cool. Now what?

Ice weasels now know of our home planet; humanity enslaved, as usual.

It looks like it bounced off twice as it landed and drifted significantly (1 KM). The active landing system designed to anchor it to the surface failed completely. It may even be lying on it's side with damaged solar panels and in a poorly lit area.

It is now stable and communicating with the orbiter. The bounces lasted for an hour each and the new location is extremely rugged. Most instruments have been activated using the battery which is good for 50 to 55 hours. According to the scientists, extraordinary data has been collected already.

More to follow on EESA

That's absolutely incredible. Thanks for posting. I couldn't imagine something like that crashing into a planet. Universe = mind fuckingly awesome.

Here is the the Flicker of some cool images.

Amazing pics. Thanks for posting.

Oh yeah, by the way, if that thing crashed into earth, how much of it would survive the burn and impact the surface you think? Enough to jack our shit nicely?

(by the way, it's about as tall as Mt. Fuji)

Next Mario Galaxy needs this as one of the planetoids you can run all over despite the low gravity.

So THAT'S where MH370 went :hmm:

What sucks about that is although it has a battery they were counting on the solar panels to keep it charged, with only a short window of sun exposure it may not be possible to keep it operational for very long. That sucks, I wanted to get the bird's eye view of it out-gassing as it approached the sun, that would have been awesome but doesn't' look like it will happen now after the decent issues.

I guess this link for the airliner size comparison would have been better:

If it hits the ocean, and you are 200 miles away, here's what its like for you:

52 mile diameter crater by 1/2" mile deep in ocean floor

64 mile diameter fireball appears 75 times larger than sun from 200 miles away

500 times hotter than sun from 200 miles away, hot enough to ignite clothing, plywood, grass and other dryer trees

9.5 magnitude earthquake

6 foot deep layer of fallout, 1" diameter particle average.

Air blast = 120psi, 1,500mph wind speed

118db sound intensity

all buildings and structures flattened

Tsunami wave 1.1 miles high 200 miles from impact

Is this assuming a rocky meteor as opposed to an easily-liquified comet?

 

[alkemyst]

if that easily-liquified comet wasn't fully consumed by our atmosphere it could be equally bad or even worst depending on size.

 

[moonbogg]

The end result isn't much different with iron, porous rock or ice. Its all pretty much Armageddon. Sure, iron has the biggest energy release, but you wouldn't know the difference from 200 miles away. You'd be like, "Glad that wave is only 1/2" mile high and shit"?

Also, LOL @ "easily liquefied" ahahah. If that thing was made from marshmallow, it would still rape your ass at 200 miles away.

I did a recalculation using ice with major differences below. Marshmallow wasn't an option, sorry.

7 mile diameter crater by 1/2" mile deep
113 times hotter than sun and 33 times larger in sky (enough to burn everything just the same, spontaneous combustion etc)
7.5 magnitude earthquake
thin layer of dust, no large rocks like before
26psi air blast, 600mph wind (not too bad right?)
all buildings still flattened
Tsunami wave only 1,600ft high. Not too bad. Grab a surf board.

I'm thinking;
- track all/most comets
- when they get close enough to Earth,...
- ,.. launch a probe,...
- ,.. probe latches onto comet
- comet goes off into the far recesses of the galaxy
- during that journey, probe takes photos along the way (probe is powered by solar panels)
- comet comes back hundreds of years later, with probe still latched onto it (provided it didn't break up or get smashed when/if the comet collided with anything,...)
- detach probe
- print out pics; hello areas of the galaxy we can't travel to (yet)

Yay science!

EDIT: it would be totally awful if the comet ripped through an alien space ship during this journey and we had the pictures of them,.. moments before collision,...

-Comets roll wildly and no single area gets a lot of sun exposure
-The energy you can collect from the sun diminishes greatly the further you are from it.

Deep space probes generally use nuclear power or RTG for a reason.

I recently heard a figure that said there are "trillions" of comets orbiting our sun.

There you go.

Rosetta: concerns for comet lander after uneven landing

The long term prognosis does not look good. Once the initial charge is gone and this is going to happen by Friday or Saturday afternoon, they will have to limit the lander's activities drastically. That's too bad.

 

[moonbogg]

Whoa, I just had a thought. Distant civilizations are observing our progress, and they use the asteroid belt which surrounds us as a kind of contingency weapon should we advance and turn hostile. The moment we turn hostile, they use their technology to guide huge meteors into our planet. So we are being watched and held at gun point and never knew it, until now. Your welcome.

should make that into a movie, with super intelligent bugs inhabiting those distant civilizations.

Is the "alright alright alright" in the topic title some kind of reference to Matthew McConaughey?

The lander bounced twice, initially about 1km back out into space, before settling in the shadow of a cliff, 1km from its intended target site.

Just a little bounce.

Hopefully they can at least figure out what caused the thruster to fail. Watch it be a component installed backwards, again.






Huh.....and here's a thought:
A person could do a pushup with only a middle finger and flip off the entire comet as they achieve escape velocity.
"So long, suckers! Enjoy your broken lander!"

Why are the pics all black and white? WTF were they thinking?
