Asteroid mining could lead to self-sustaining space stations - VIDEO!!! - 5 views

  •  
    Let's all start up some crazy space companies together: harvest hydrogen on Jupiter, trap black holes as unlimited energy supplies, use high temperatures close to the sun to bake bread! Apparently it is really easy to do just about anything and Deep Space Industries is really good at it. Plus: in their video they show Mars One concepts while referring to ESA and NASA.

    I really wonder what they wanna mine out there? Is there such a high demand on... rocks?! And do they really think they can collect fuel somewhere?
  •  
    Well they want to avoid having to send resources into space and rather make it all in space. The first mission is just to find possible asteroids worth mining and bring some asteroid rocks to Earth for analysis. In 2020 they want to start mining for precious metals (e.g. nickel), water and such.They also want to put up a 3D printer in space so that it would extract, separate and/or fuse asteroidal resources together and then print the needed structures already in space. And even though on earth it's just rocks, in space a tonne of them has an estimated value of 1 million dollars (as opposed to 4000 USD on Earth). Although I like the idea, I would put DSI in the same basket as those Mars One nutters 'cause it's not gonna happen.

    I will get excited once they demonstrate they can put a random rock into their machine and out comes a bicycle (then the obvious next step is a space station).

    hmm aside from the technological feasibility, their approach still should be taken as an example, and deserve a little support. By tackling such difficult problems, they will devise innovative stuffs. Plus, even if this doom-to-fail endeavour may still seem you useless, it creates jobs and make people think... it is already a positive! Final word: how is that different from what Planetary Resources plan to do? It is founded by a bunch of so-called "nuts" ... (http://www.planetaryresources.com/team/) ! a little thought: "We must never be afraid to go too far, for success lies just beyond" - Proust

    I don't think that this proposal is very different from the one by Planetary Resources. My scepticism is rooted in the fact that - at least to my knowledge - fully autonomous mining technology has not even been demonstrated on Earth. I am sure that their proposition is in principle (technically) feasible but at the same time I do not believe that a privately funded company will find enough people to finance a multi-billion dollar R&D project that may or may not lead to an economically sensible outcome, i.e. generate profit (not income - you have to pay back the R&D cost first) within the next 25 years. And on that timescale anything can happen - for all we know we will all be slaves to the singularity by the time they start mining. I do think that people who tackle difficult problems deserve support - and lots of it. It seems however that up till now they have only tackled making a promotional video... About job creation (sorry for the sarcasm): if usefulness is not so important my proposal would be to give shovels to two people - person A digs a hole and person B fills up the same hole at the same time. The good thing about this is that you can increase the number of jobs created simply by handing out more shovels.

    Check the landing video from the onboard camera - Guido: how well would our optical flow algorithm cope with such images? Looks quite complicated to me....

    Note that videos there are said to be "thumbnail" quality, so I think videos with higher resolution (and possibly frame rate) have been acquired, just that they were not downloaded yet.

    A lot of lectures from the MIT put on video - could not only be model for our stuff, but also useful source of knowledge for the individual.

    [spam] Obama expressed his disappointment recently when rapper Kanye West stormed the stage at the MTV Video Music Awards to protest singer Taylor Swift's win of the "Best Female Video" trophy. Soon after, Obama himself was Swifted by critics who felt he was undeserving of his Nobel Prize win. It is obviously connected to the study of the Journal of Wine Economics that wine gold awards are given randomly http://www.wine-economics.org/journal/content/Volume4/number1/Full%20Texts/1_wine%20economics_vol%204_1_Robert%20Hodgson.pdf which also raised some controversy

    this is what I call truly cloaking!...of course only found in and made by nature :) (video at the bottom of the page)
  •  
    Definitely beautiful, even psychedelic maybe.. but technically its not really cloaking, you wouldn't call your window a cloaking device right? :)
  •  
    The video looks surreal!

    New form of locomotion found in spiders. They say it could be used for a robot on Mars...don't immediately see how though. :)

    Before it gets out of control... I hope you realise that quoting "Science Daily" in the context of science is pretty much like using Daily Mail as your reference news agency?
  •  
    I was just going to post the same story. Here is BTW a video of the intended type of robot: https://www.youtube.com/watch?v=OHo32JrkDRk&feature=youtu.be
  •  
    True Marek :) The article does quote a Journal Paper though ..... published in zootaxa: a staggering 0.9 impact factor journal!! And watching the video you immediately understand why :)
  •  
    I of course watched the video and have trouble sleeping since.

Hayabusa Sample Return Capsule Entry - Airborne Observing Campaign - 0 views

  • An attempt will be made to provide a live video feed of the Hayabusa Re-Entry in the minutes around the re-entry at 13:51 UT, Sunday June 13. The video will be chosen from cameras operated onboard NASA's DC-8 Airborne Laboratory
  •  
    After reading the Hayabusa's story posted by Joris a while ago, I think that the only adequately epic final to conclude this awesome mission is that the capsule will land safely. And empty.
