Lost Beagle 2 spacecraft found intact on Martian surface - 0 views

  •  
    The UK-led Beagle 2 Mars lander, thought lost on the red planet since 2003, has been found partially deployed on the Martian surface. New images show that it successfully touched down on the planet's surface in 2003 but failed to deploy all four of its solar panels, thereby allowing no communication with scientists on Earth.

Spotting East African Mammals in Open Savannah from Space - 1 views

  •  
    A hybrid image classification method was employed for this specific purpose by incorporating the advantages of both pixel-based and object-based image classification approaches. This was performed in two steps: firstly, a pixel-based image classification method, i.e., artificial neural network was applied to classify potential targets with similar spectral reflectance at pixel level; and then an object-based image classification method was used to further differentiate animal targets from the surrounding landscapes through the applications of expert knowledge. As a result, the large animals in two pilot study areas were successfully detected with an average count error of 8.2%, omission error of 6.6% and commission error of 13.7%. The results of the study show for the first time that it is feasible to perform automated detection and counting of large wild animals in open savannahs from space

    And Paul, it includes neural networks!

    I kept telling you guys but you just laughed and laughed :))

New apps allow smartphone users to join the hunt for ultrahigh-energy cosmic rays - 0 views

  •  
    Two apps - the Distributed Electronic Cosmic-ray Observatory (DECO) and Cosmic Rays Found in Smartphones (CRAYFIS) - transform smartphones into miniature cosmic-ray detectors. They use the CMOS chips inside phones' onboard cameras to detect the secondary particles produced when cosmic rays - energetic, charged subatomic particles arriving from beyond the solar system - collide with air molecules in the Earth's atmosphere

Cloud cities for Venus exploration - 3 views

  •  
    Our friends from NASA have come out with a plan to the human exploration of Venus in the time that everyone is speaking about Mars.
  •  
    Love the concept acronym, which pretty much says it all... Not sure which astronaut would fancy floating around in an atmosphere where clouds are made of sulphuric acid.
    Besides I don't see the point of a manned mission if one can't reach the surface.. tele-operation would be easy and so much cheaper.

Direct brain-to-brain communication demonstrated in human subjects -- ScienceDaily - 2 views

  •  
    In a first-of-its-kind study, an international team of neuroscientists and robotics engineers has demonstrated the viability of direct brain-to-brain communication in humans.
  •  
    Was just about to post it... :) It seems after transferring the EEG signals of one person, converting it to bits and stimulating some brain activity using magnetic stimulation (TMS) the receiving person actually sees 'flashes of light' in their peripheral vision. So its using your vision sense to get the information across. Would it not be better to try to see if you can generate some kind of signal in the part of your brain that is connected to 'hearing'? Or would this be me thinking too naive?

    "transferring the EEG signals of one person, converting it to bits and stimulating some brain activity using magnetic stimulation (TMS)"

    How is this "direct"?

UK promises commercial spaceport 'by 2018' with 6 of 8 potential locations in Scotland - 0 views

  •  
    not sure what to make of this. seems like an odd change of direction

    "Spaceports will be key to us opening up the final frontier of commercial space travel," said Chief Secretary to the Treasury Danny Alexander at the announcement of the new sites. Mr Alexander hinted that the plans could lead to Scotland becoming the home of the UK's commercial space ambitions, even as the Scottish government warns that only independence will secure a successful space industry for the country.

Aerospace Industry Trends & Events - 1 views

  •  
    Hey guys,
    I thought I would forward you a link to a newsletter on Aerospace Tech. It is mainly on the engineering level - but after all that was an area where a lot of people in the team felt they missed expertise. So here you go! ;-)
    The newsletter is a mix of stories on new trends and of advertisement of high-tech parts by aerospace suppliers. IHS Global Spec also has similar newsletters on other research fields (e.g. piezoelectrics). Hope this is useful for some people.

Google plans for internet from space with 180 LEO satellites - 2 views

  •  
    The Wall Street Journal hears that the search firm is preparing to build 180 "small, high capacity" satellites that will go into low orbit and provide internet connections to underserved areas
  •  
    sorry, did not see your earlier post ...
    fully altruistic move of course as they claim
  •  
    actually I posted about it first :P

Norwegian army driving tank using Oculus Rift - 1 views

  •  
    I guess it might also make sense to put a camera on an extension to look around corners without having to advance the vehicle to where it can be shot at...
    ?: Could the Oculus be used to let humans control humanoid robots? I guess so. Could humans perform experiments using such robots? Probably. Could Oculus be used to control these robots on the ISS? I guess so. --> Finally we eliminated the last need for humans in space!!! :-D
    (Maybe we could replace humans on Earth with robots that control one another through Oculus Rift...)
  •  
    Even cooler would be to have like a swarm of drones around the tank to act as a sensor array and look around corners for you.

F9R First Flight Test - 3 views

  •  
    In case you have not seen this one yet...
  •  
    Nice one, very impressive (also filming it with a drone :)! I noticed at 0:56 that the exhaust flames do travel upwards on the descent. I wonder how much of a problem this would be for the actual reusability / next flight approval?
  •  
    impressive!

    Article mainly on anti-satellite testing by the Chinese and on US and Russian tests (2nd page) - quite extensive and technical but interesting

Iridium to introduce WiFi hotspots for global satelite internet - 2 views

  •  
    In remote / under-developed regions this might actually be a strong alternative for building internet connectivity - somewhat like the exploding market for cell phones in Africa due to the lack of land lines.

Light-weight membrane optics test for building large telescopes in space #DARPA - 1 views

  •  
    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.

Evidence for High-Energy Extraterrestrial Neutrinos at the IceCube Detector - 1 views

  •  
    IceCube detects a neutrino in about every 6 minutes but most are from within the solar system. A small number of very high energy neutrinos have been found though which have energies that cannot be produced by the sun or on Earth.

    Yes. Worked.

Snake Robots for Exploration - 1 views

  •  
    The researchers are busy working on a feasibility study assigned to them by the ESA. The idea is that by combining a rover that can navigate over large distances with a snake robot that can crawl along the ground and can get into inaccessible places, so many more possibilities could be opened up, e.g. collecting samples from tight spots that the rovers cannot reach.

    165000 people have applied and the founders of Mars One still seem enthusiastic. Wouldn't it be great if they actually could pull it off..?
