Amazing job! This might be a silly question but are their any ideas as to the actual real world benefits we could see from this? The director-general of the ESA said "This is a big step for human civilisation" so I presume there is some idea of what they expect to gain from this mission? Edit: Thanks for all the replies! I'm at work now but will take a look at them this evening.

i watched a docu on the large hadron collider and the search for the higgs boson particle where they asked one of the scientists a similar question. what do you expect to gain monitarily from that xBillion dollars we just spent on this? his reply was 'i don't know'. he went on to give the example of how when radio waves were first discovered nobody called them 'radio waves' because no one had thought to use them in t…

Reminds me of a great conversation in The West Wing (one of the best written shows ever made, in my opinion).

A senator (ENLOW) has put an anonymous hold on building a supercollider, the white house deputy communications director (SAM) wants to help his old professor (MILLGATE) get the budget approved for it, and this is near the end of the episode:

  ENLOW
  I'm a Democrat, Sam. How's a 20 billion dollar astronomy lecture gonna help
  the President get elected?
  
  SAM
  It won't. "We've discovered a seamless, intellectual framework for the
  universe" isn't a good 30-second spot.
  
  ENLOW
  If only we could only say what benefit this thing has, but no one's been 
  able to do that.
  
  MILLGATE
  That's because great achievement has no road map. The X-ray's pretty good. 
  So is penicillin. Neither were discovered with a practical objective in 
  mind. I mean, when the electron was discovered in 1897, it was useless. And 
  now, we have an entire world run by electronics. Haydn and Mozart never 
  studied the classics. They couldn't. They invented them.
  
  SAM
  Discovery.

  MILLGATE
  What?

  SAM
  That's the thing that you were... Discovery is what. That's what this is used 
  for. 
  It's for discovery.

Anyone knows where i could find some info about the software stack this kind of probes are being built with ? Languages, programming methods, patching methods,os, runtime, etc. I'm really curious to know how different it is from the web or enterprise development worlds.

Most likely they have headless web browsers running on both the main spacecraft (probably chromium) and the Philae lander. Web sockets enables the lander to communicate to the spacecraft which then sends its signals down to earth using regular HTTP (you don't want to keep an interstellar HTTP connection open). All of it is of course written in JavaScript, more specifically vanilla-JavaScript - which frankly I find we…

All this without docker? Their devops team is seriously behind the times...

Absolutely stunning feat of engineering. My bosses are on the drill team for Philae and were amongst the nervy faces being beamed all over the world. Great example of what European nations can do when politics don't get in the way. ExoMars [1] and Bepi-Colombo [2] are perfect examples of the inverse. Look forward to the first pictures from the surface. I'm at the Division on Planetary Sciences (DPS) meeting [3] in Tu…

At the risk of turning political, it's a great example of how our taxes are wasted. Playing with space toys shouldn't be funded with taxpayer money.

I'm sure I'll get downvoted to hell for this, but why should my money be funding this? Sorry, but it has no benefit whatsoever.

edit: Instead of downvoting a dissenting voice, why not argue your case - why should taxpayers fund space toys?

edit2: Well, looks like I'm banned from commenting. Good job dealing with those that don't agree with you...

More analysis of @Philae2014 telemetry indicates harpoons did not fire as 1st thought Ouch, seems like it didn't land? https://twitter.com/esaoperations/status/532575061543485440 edit - the landing is confirmed, however the harpoons did not fire: https://twitter.com/ESA_Rosetta/status/532579871202238464

Emily Lakdawalla tweets from the control center: Ulamec: signal kept coming and going "but we always got it back." Possibly indicates unstable, or tilted. Ulamec confirms the harpoons did NOT fire. There is much they currently do not know. Ulamec: a central rod was pushed into lander 4 cm by landing. Indicates soft rather than hard surface (rod would've pushed more into lander) Just had a chat with Mark McCaughrean a…

Man, measuring how far a rod moves into the lander to gauge depth/surface tension/type? So simple and smart.

Care to give a hint about what kind of results those are?

I 'd dare you to specify what's more important where your money should be spent.

Congratulations Europe. But why don't we hear people saying that the EU should focus on their poverty first and would be better off putting this money into getting the Greece, Spain, and Italy economies in order?

[deleted]

There are some very poor parts of Europe - some with poverty levels almost as bad as rural America.

Earlier quoted context omitted.

Thanks. I would definitely consider the second point a real world benefit but if we are going to spend over $1bn to learn about the solar system's history I take it we are hoping to discover something that actually has benefits to humanity (e.g. when the money could have had more immediate impacts treating disease or helping the poor etc.). Don't get me wrong I'm all for these kinds of missions I just thought that to…

If you want to talk about spending priorities, how about the folly of the Iraq war, trident, etc. those cost huge amounts more than this mission? Not everyone has the same priorities as you. Thank goodness at least some of our money is spent on things which might benefit humanity in the long term , like discovering how the solar system was formed or whether life was formed on earth or elsewhere.

...where did I indicate I would rather spend that money on war and weapons? My comment actually states: "Don't get me wrong I'm all for these kinds of missions".

As for your long term benefits:

Great so we find out how the solar system is formed or where life was formed - now what? Those are really cool things to know but what do we do with that information? The reason I'm curious about this is that although I want to see more of these missions and I think it would be great to have answers to those questions I find it difficult to actually justify spending that money on answering questions. There must be some tangible benefit. Other responses to my question have provided me with answers to that.

"Philae has made the first, historic landing on a comet, after descending from its mothership"

To me, no other statement could be more impacting. Earth is finally sending motherships to space. feeling mind-boggled
