    According to the article it seems that the growth of biofilms in space (MIR, ISS) is continuing to be a challenge for any space missions. Hardly any information is present on what role gravity plays in their growth and development. Maybe detection is also one important aspect of this indeed (Tom?)

    Using light-weight membranes to build telescopes in space it may be possible to one day image the whole planet completely at high resolution, hence also the interest of darpa.

    The new findings come from a recent NASA study in which 12 astronauts aboard the ISS took ultrasound images of their hearts before, during, and after their six-month stint in space. What they found confirmed scientists' previous prediction: In microgravity, the human heart becomes more spherical by a factor of nearly 10 percent.

    Nice link and clear overview! I like the point raised about 1000 man in space, even when including automation (as far as they could envision at the time). Now that is a future of the space industry and permanent habitation of near-earth orbits! In fact, I can envision just two reasons maybe, power and the hotel industry

    Researchers in Bangalore, India together with the Indian Space Research organization come up with an intelligent self-healing algorithm that can locate open-circuits faults and repair them in real-time. They used an insulating silicon oil containing conductive particles. Whenever a fault happens, an electric field develops there, causing the fluid to move in a 'thermodynamic automaton' way repairing the fault. The researchers make clear it could be one advantage for electronics in harsh environments, such as in space satellites.

    Strange and exotic cityscapes. Desolate wilderness areas. Dogs that look like wookies. Flickr, one of the world's largest photo sharing services, sees it all. And, now, Flickr's image recognition technology can categorize more than 11 billion photos like these. And it does it automatically. It's called "Magic View." Magical deep learning! Buzzword attack!

    and here comes my standard question: how can we use this for space? fast detection of natural disasters onboard?
  • Alexander Wittig on 22 Jul 15
     
    Even on ground. You could for example teach it what nuclear reactors or missiles or other weapons you don't want look like on satellite pictures and automatically scan the world for them (basically replacing intelligence analysts).
  • Alexander Wittig on 23 Jul 15
     
    In fact, I think this could make a nice ACT project: counting seals from satellite imagery is an actual (and quite recent) thing: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0092613 In this publication they did it manually from a GeoEye 1 b/w image, which sounds quite tedious. Maybe one can train one of those image recognition algorithms to do it automatically. Or maybe it's a bit easier to count larger things, like elephants (also a thing).

    In HiPEAC (High Performance, embedded architecture and computation) conference I attended in the beginning of this year there was a big trend of CUDA GPU vs FPGA for hardware accelerated image processing. Most of it orbitting around discussing who was faster and cheaper with people from NVIDIA in one side and people from Xilinx and Intel in the other. I remember of talking with an IBM scientist working on hardware accelerated data processing working together with the Radio telescope institute in Netherlands about the solution where they working on (GPU CUDA). I gathered that NVIDIA GPU suits best in applications that somehow do not rely in hardware, having the advantage of being programmed in a 'easy' way accessible to a scientist. FPGA's are highly reliable components with the advantage of being available in radhard versions, but requiring specific knowledge of physical circuit design and tailored 'harsh' programming languages. I don't know what is the level of rad hardness in NVIDIA's GPUs... Therefore FPGAs are indeed the standard choice for image processing in space missions (a talk with the microelectronics department guys could expand on this), whereas GPUs are currently used in some ground based (radio astronomy or other types of telescopes). I think that on for a specific purpose as the one you mentioned, this FPGA vs GPU should be assessed first before going further.
  • Paul N on 29 Jul 15
     
    You're forgetting power usage. GPUs need 1000 hamster wheels worth of power while FPGAs can run on a potato. Since space applications are highly power limited, putting any kind of GPU monster in orbit or on a rover is failed idea from the start. Also in FPGAs if a gate burns out from radiation you can just reprogram around it. Looking for seals offline in high res images is indeed definitely a GPU task.... for now.

    The discussion of how to make FPGA hardware acceleration solutions easier to use for the 'layman' is starting btw http://reconfigurablecomputing4themasses.net/.

    very nice success by what we called in 2003 "the second space age" ... for Joris: (related to the discussion we had the other day) But the spacecraft will be assembled, integrated and tested in the United States and will include U.S. hardware, meaning they would not be allowed for launch aboard Indian or Chinese rockets under current U.S. regulations.

    too late, the world will in end in 2012 ......... I fail to see in which scenario this would be better than a couple of vaults on Earth (since there would be no humans on the moon). But if tulips on the moon can convince politicians, I'm all for it.

    "The first flowers - tulips or arabidopsis, a plant widely used in research - could be grown in 2012 or 2015 according to Bernard Foing, chief scientist at the agency's research department." - Bernhard strikes again :-)

    Also, this reminds me of a poem that once sprung out on my Linux console login: The wombat lives across the seas, Among the far Antipodes. He may exist on nuts and berries, Or then again, on missionaries; His distant habitat precludes Conclusive knowledge of his moods, But I would not engage the wombat In any form of mortal combat.
