New Horizons made its closest approach to Pluto this morning, but it’s actually too busy observing to transmit right now, plus it’s so far away that it takes hours for the signal to get here.
But if this picture, which it took from about 50 times as far away, is any indication, the closeup ones should be incredible.

I’m a little behind with this; I was deliberately holding back for a couple of reasons.
I wrote about a “quantum vacuum plasma thruster”, in other words a device similar to the one that this latest news involves, a few times during the early days of this blog, never really saying much about it myself. Since then, I’ve done more research, and found that the variety of explanations for how it’s supposed to work is wider than I’d been aware of, but none of them seem to be very likely and some of them violate the law of conservation of momentum. Nonetheless, there does seem to be some evidence that the EmDrive does in fact work somehow.

As Phil Plait and others point out, the evidence on this one really isn’t sufficient to be getting attached to such extraordinary claims yet.
I still think it does have better odds than I would have given the faster-than-light neutrinos when they were first announced, though.
It sounds like something out of science fiction (especially when you call it that), but NASA says it works.
It seems to defy conservation of momentum and may work by interacting with virtual particles. And since three independently built ones have seemed to work, it probably isn’t an error.
