    Data-Visualization Firm's New Software Autonomously Finds Abstract Connections --> Annalisa?
  •  
    I had a nice introduction about Ordinal Regression via Manifold Learning by Francisco last week. It is doubtless a very actual research branch!
  •  
    I doubt :) The original paper from Liu is from 2011 and has .... wait for it .... 1 quotation (and a self-one)!!! http://scholar.google.it/scholar?hl=it&q=Ordinal+Regression+via+Manifold+Learning&btnG=&lr=

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.

An extensive and autonomous deep space navigation system using radio pulsars :: TU Delf... - 4 views

  •  
    Interesting. these guys are apparently gonna try developing pulsar navigation. They propose to solve the low apparent brightness problem using relatively complex signal processing and filtering to limit the antenna size etc. The say they've already had some promising results using ground based data. worth a science coffee perhaps?
  •  
    Absolutely. Sante can you get in contact with them?

NASA investigates sending CubeSats to Phobos and back - 3 views

  •  
    NASA's Innovative Advanced Concepts Program provides funding to study a small number of highly advanced spaceflight concepts, with the goal of understanding the technological possibilities which will guide the development of future space missions. Under this program, a JPL (Jet Propulsion Laboratory) researcher has proposed the use of a pair of CubeSats for an autonomous mission to retrieve samples from Phobos, Mars' larger moon.

Joggobot turns a quadrocopter into a running companion - 3 views

  •  
    Joggobot turns a quadrocopter into a running companion Researchers from RMIT in Melbourne, Australia have developed a flying running companion called Joggobot. The system uses the built-in camera on a commercially-available Parrot AR Drone quadrocopter to track the position of a jogger, and fly a few feet out in front.

NASA set to debut online software catalog April 10 - 1 views

  •  
    The catalog, a master list organized into 15 categories, is intended for industry, academia, other government agencies, and general public. The catalog covers technology topics ranging from project management systems, design tools, data handling, image processing, solutions for life support functions, aeronautics, structural analysis, and robotic and autonomous systems. NASA said the codes represent NASA's best solutions to an array of complex mission requirements. McMillan reported that "Within a few weeks of publishing the list, NASA says, it will also offer a searchable database of projects, and then, by next year, it will host the actual software code in its own online repository, a kind of GitHub for astronauts."

Repeated self-healing in composite materials - 1 views

  •  
    Sottos, White, Moore, and their team created 3D vascular networks-patterns of microchannels filled with healing chemistries-that thread through a fiber-reinforced composite. When damage occurs, the networks within the material break apart and allow the healing chemistries to mix and polymerize, autonomously healing the material, over multiple cycles.

Spaceflight Now | Breaking News | ESA needs to 'tighten the belt' amid budget crisis - 2 views

  • ESA is freezing spending
  • France is planning to boost its funding by 12 percent
  • ESA selected Thales Alenia Space and OHB Technology to build the satellites, but the production contract is still bogged down by Germany's complaints about the distribution of MTG work between France and Germany
  •  
    no much news in regard to the january's talk of Dordain althought just a thought : what if ESA tries to make money - as CNES does - rather than just spending it ?
  • ...1 more comment...
  •  
    to begin with european industry (and probably governments) would complain that ESA was taking business away from industry? or any part that started to make money would be quickly spun-off
  •  
    really bad interview in my view ... btw: how is CNES making money and how much?
  •  
    CNES is known to be a semi-autonomous agency in the sense that it can auto-finance parts of its activities. Besides the money coming from the state, money comes from the participation of CNES in private companies (e.g. Arianespace) and its own activities (e.g. SPOT among others...). It is about 400M€ per year (almost a class-M mission in Cosmic Vision). For the figures (in French): http://www.cnes.fr/automne_modules_files/standard/public/p4354_c050f7963b54a839a843723401bfddf2budget.pdf

X-37B military spaceplane launches from Cape Canaveral - 1 views

  • The X-37B, which has been likened to a scaled-down space shuttle, blasted off from Cape Canaveral Air Force Station at 0052 BST (1952 EDT).
  • The X-37B, which has been likened to a scaled-down space shuttle, blasted off from Cape Canaveral Air Force Station at 0052 BST (1952 EDT). The military vehicle is unpiloted and will carry out the first autonomous re-entry and landing in the history of the US space programme.
  • In all honesty, we don't know when it's coming back for sure.
