Nasa validates 'impossible' space drive (Wired UK) - 3 views

  •  
    NASA validates the EmDrive (http://emdrive.com/) technology for converting electrical energy into thrust.

    (from the website: "Thrust is produced by the amplification of the radiation pressure of an electromagnetic wave propagated through a resonant waveguide assembly.")

    I would be very very skeptic on this results and am actually ready to take bets that they are victims of something else than "new physics" ... some measurement error e.g.
  •  
    Assuming that this system is feasible, and taking the results of Chinese team (Thrust of 720 mN http://www.wired.co.uk/news/archive/2013-02/06/emdrive-and-cold-fusion), I wonder whether this would allow for some actual trajectory maneuvers (and to which degree). If so, can we simulate some possible trajectories, e.g. compare the current solutions to this one ?

    For example, Shawyer (original author) claims that this system would be capable of stabilizing ISS without need for refueling.

    Other article on the same topic: http://www.theverge.com/2014/8/1/5959637/nasa-cannae-drive-tests-have-promising-results
  •  
    To be exact, the chinese reported 720mN and the americans found ~50microN. The first one I simply do not believe and the second one seems more credible, yet it has to be said that measuring such low thrust levels on a thrust-stand is very difficult and prone to measurement errors.

    @Krzys, the thrust level of 720mN is within the same range of other electric propulsion systems which are considered - and even used in some cases - for station keeping, also for the ISS actually (for which there are also ideas to use a high power system delivering several Newtons of thrust).

    Then on the idea, I do not rule out that an interaction between the EM waves and 'vacuum' could be possible, however if this would be true then this surely would be detectable in any particle accelerator as it would produce background events/noise. The energy densities involved and the conversion to thrust via some form of interaction with the vacuum surely could not provide thrusts in the range reported by the chinese, nor the americans. The laws of momentum conservation would still need to apply.

    Finally, 'quantum vacuum virtual plasma'.. really?

    Eh, the swarm flyby gravimetry is very similar to the "measuring gravitational fields" project I proposed in the brewery

Noordwijk | Space Apps Challenge - 1 views

  • On the weekend of the 12 and 13 April 2014 ESA Business Incubation Centre Noordwijk and Verhaert Connect are proud to host the NASA International Space Apps Challenge in the European Space Innovation Centre Noordwijk.
  • Developers, designers, innovators all kinds of creative thinkers from all seven continents will come together for two days of creativity and computer coding to address challenges of global importance. This year we expect to have about 40 challenges that support NASA's mission directorates in five themes: Earth Watch, Technology in Space, Human Spaceflight, Robotics and Asteroids.
  •  
    "Developers, designers, innovators all kinds of creative thinkers" aka "nerd objective-C programmers with no life"?
  •  
    Well, the ACT actually proposed a few of the topics (BEWARE, THERE BE CUCUMBERS!). Some are not necessarily software based, like creating a LEGO model of the ExoMars rover (although they stripped LEGO from the challenge description and now it just says "create an ExoMars rover from hardware" ... ). Also we had no clue that they would host part of the challenge here at ESTEC - so our 5 or 6 challenges will all be hosted in Rome... ...

NASA will send robot drill to Mars in 2016 - The Washington Post - 0 views

  • A German-built drill nicknamed “The Mole” will pound 16 feet into the Martian crust to take the temperature of the planet, while a sensitive French-built seismometer will detect any Marsquakes.
  •  
    slashdot describes the drill as "a self-driving mole developed by the German space agency (DLR)".

    This seems to be the drill: GEMS - a mole to explore the interior of Mars, http://dx.doi.org/10.1109/OCEANSE.2009.5278132.

    Interesting news for all the roots people :)

    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.

    Not so good news ...

    Have a look at the US budget and the incredible amount of money they are spending for military purposes.

    It's as simple as that.

Fly into Solar Radiation Storm (First ACT member into space !) - 1 views

  •  
    " This isn't Camilla's first adventure. The chicken has also flown on a NASA T-38 training jet, traveled onboard a helium balloon to the stratosphere over Louisiana, visited the Yuri Gagarin Cosmonaut Training Center in Star City, Russia, and visited hundreds of elementary students in classrooms around the country. "
    Pretty impressive Camilla ! Congratulations :)

NASA - 2011 NIAC Phase I Selections - 7 views

  •  
    very nice selection of projects by NIAC!! there are at least some who have European partners as it looks like ... lets still see if we can get involved ...
  •  
    Interesting. Is it NASA's equivalent of ESA's GSP?
  •  
    It is a good thing NIAC is alive again.

    Wie, Bong -> "Optimal Dispersion of Near-Earth Objects" . I wonder what it is?

A Fusion Thruster for Space Travel - IEEE Spectrum - 4 views

  • Now a NASA engineer has come up with a new way to fling satellites through space on mere grams of fuel, tens of times as efficiently as today’s best space probe thrusters.
  • Instead of using deuterium and tritium as the fuel stocks, the new motor extracts energy from boron fuel.
  •  
    "And according to his calculations, improvements in short-pulse laser systems could make this form of thruster more than 40 times as efficient as even the best of today's ionic propulsion systems that push spacecraft around. "
  •  
    Dejan please have a look at this also ...
  •  
    while the nuclear reaction seems to be sound at first view, I am not so sure how this would work: "Electromagnetic forces push the target and the alpha particles in the opposite directions, and the particles exit the spacecraft through a nozzle, providing the vehicle's thrust. "
