    $100,000 from NASA's Innovative Advanced Concepts program to hammer out a design and figure out whether spacecraft self-construction makes business sense .... I can answer for 0$ ..... NO Infact the question is just stupid: a) spacecraft self-construction exist: then it is a no brainer to decide wether it makes business sense b) it does not: then there is no business

    NASA's Kepler space telescope could be used to find exomoons, which are the moons of planets orbiting stars other than the Sun. That is the claim of an international team of astronomers, which says that careful analysis of data collected by Kepler could reveal if such exoplanets are circled by moons.

    U.S. scientists say they're working on mini-satellites that could function as "space cops" to help avoid collisions in space of satellites and space debris. Researchers at the Lawrence Livermore National Laboratory in California have tested a ground-based satellite to prove it is possible to refine the orbit of another satellite in low Earth orbit.

    In follow up of our discussion yesterday, what would be required to get private investment to keep an orbiting station going? Do we actually want to? On the side, at least the budget for NASA seems to make it unlikely to be able to afford both ISS and a beyond-Earth orbit exploration program (http://www.americaspace.com/?p=36568)

    They were able to compare the ticking rates of two optical clocks separated by 2000 km, with the objective of computing sea level based on the effect gravity has on the clock ticking rate. They did the experiment using glass optical fibers, but I wonder if we could one day do the same from orbit, to measure the gravitational field around Earth.

    The novel part here is that it can be scaled down to the cubesat platform. I then wondered, could we place multiple of such Cubesats in a 'decaying orbit' around the Sun? Fractionated will give spatial and temporal information which, even with a simple langmuir probe setup, can give information on density, temperature, velocity, ion energy distribution, potential.. Of course they will be lost relatively quickly, but more could be ejected from a mother ship which is orbiting at a safer distance.

    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!

  • 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.

Phantom menace to dark matter theory - space - 08 July 2009 - New Scientist - 0 views

shared by pacome delva on 05 Aug 09 - Cached
  • If MOND exists, it will appear as if there is an anomalous, "phantom" mass in that region, exerting a gravitational force on the bodies in our solar system.
  • According to Milgrom, this force should cause the orbits of the planets to precess - that is, their elliptical orbits around the sun should slowly change their orientation, over time tracing out a pattern like the petals of a flower.
