NASA To Deploy Four Spacecraft To Study Magnetic Reconnection 29

Zothecula writes: NASA has released a video depicting the initial deployment of an undertaking designed to study a phenomenon known as magnetic reconnection. "Reconnection happens when magnetic field lines explosively realign and release massive bursts of energy, while hurling particles out at nearly the speed of light in all directions. Magnetic reconnection powers eruptions on the sun and – closer to home – it triggers the flow of material and energy from interplanetary space into near-Earth space." The launch of the Magnetospheric Multiscale (MMS) mission will see four identical spacecraft deployed from a single Atlas V rocket, set to lift off from cape Canaveral, Florida, no earlier than March next year.

  • It will be interesting to see whether this research on the phenomenon in the large scale produces insights useful at the smaller scale of fusion plasma confinement.

    In case it's not clear, magnetic reconnection is a phenomenon of magnetic field/plasma interaction. (Without the plasma and its currents (or extreme accelerations like those around black holes) the magnetic field wouldn't be simultaneously twisted up and bent around so it can reconnect differently.

    I see two ways this might apply to plasma confi

    • Re your sig: Jobs are not the goal. Make a basic income available to everyone (funded by the Fed, not the taxpayer, at zero cost). Hold challenges, public and private, to stimulate innovation.

      • Make a basic income available to everyone (funded by the Fed, not the taxpayer, at zero cost).

        The point is that it's not zero cost. Every penny of money "funded by the Fed" comes from your and my pockets - sometimes with a big multiplier - by paths that are not as obvious, but just as costly, as a tax bill.

        The biggest one is inflation: If the Fed just prints money, it dilutes the rest of the money. Your wages go down (though the numbers don't change.) Got retirement savings? They go down, too. Your in

  • ...this means further study can be carried out on the South Atlantic Anomaly which is a continuing risk to pretty much anything which crosses its boundaries (which Hubble and the ISS do an average of 3 times a day each)

  • Considering the terrible back luck all space agencies seem to have had with deploying tethers (getting stuck, snapping, etc) - they plan on deploying 4 per satellite? I hope there are contingency plans or someone really thought long and hard about possible failure modes and engineered around them.

Keep up the good work! But please don't ask me to help.
