    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.
  • anonymous on 02 Aug 14
     
    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.

    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?

    nice - did not know about it. GTOC on steroids and with loads of cash. concerning this specific challenge and especially the last condition: doesn't this hint towards a flawed design? In addition to maximizing the total power output there are some constraints on the possible movements: Each SARJ and BGA is limited to a maximum angular velocity and to a maximum angular acceleration. Each SAW must produce at least some minimum average power over the orbit (which is different for each SAW). The sequence of positions must be cyclic, so it can be repeated on the next orbit. The maximum amount of BGA rotation is not limited, but exceeding a threshold will result in a score penalty. Some structural members of the SAW mast (called Longerons) have restrictions on how they can be shadowed.
  • Joris _ on 26 Jan 13
     
    The longerons will expand and contract with exposition to sun (I think whatever the material they are made of). Because you have 4 longerons in a mast, you just need to be carefull that the mast is well balanced, and that the 4 longerons support each other, basically, you need an even number of shadowed longerons, possibly 0 too. I would call this an operational constraint.

    Two aerospace companies are teaming up to launch giant space habitats to orbit, with the first such liftoff targeted for 2020. Bigelow Aerospace will loft its giant, expandable B330 modules - each of which will provide one-third as much usable volume as the entire International Space Station (ISS) - aboard United Launch Alliance (ULA) Atlas V rockets, representatives from both companies announced today (April 11).

    "Two sets of [ ATV docking training for astronauts ] lessons are now available for the home user to try." And in case you wonder *where* in the earth are they available, the links are on the right-hand column (also known as ESA's scorn on usability). As usual for the material located there, I took me a few minutes to find them...

    Well I tried and could not locate the app to download from these links and sent them a feedback on what I thought a wrong error - though the email bounced :-) So, what is the right link to the app then?
  • Ma Ru on 13 Apr 12
     
    Leo, I'm not iEnabled, so I can't help you with the app. Using other links you can try the PC version (so 20th-century-ish, I know), of course assuming you have somewhere one with Internet Explorer :-)

    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?)

    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.

    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...)
  • Paul N on 06 May 14
     
    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.
