Cruise | Interplanetary dust

Since the trajectory to Alpha Centauri would take the nanocrafts away from the ecliptic plane of the solar system, there would be much less impact from solar system dust than from interstellar dust.

Little is currently known about the dust content in the Alpha Centauri star system.

    Maybe it would be possible to augment the laser array to interact with the stellar dust, and fire bursts prior to launch? If there would be some way to measure how the beam interacts with stellar dust in our system, that data could be used to either clear a path, or find out other possibilities.
    Alternatively, maybe a first wave could be sent prior to launch with sails that are designed to clear a path to minimize impact with the more sensitive Starchips. Just a few thoughts, such an incredible endeavor.

    With two suns in the AC I would think dust would not be very common, that's a lot of light to move them about.

    The luminosity of alphaC A and B are similar to the Sun, so not clear that the situation is much better than the Solar System.

    The laser interacting with the dust would not matter because it would be too weak by that point to do anything. I do not know this but I think so.

    Answer:
    You are correct the earth based laser maybe powerful enough to clear the path to Mars orbit. But much past that it will not have enough power to move the particles out of the way. Thank you for your ideas.
