Sincerity of the various researchers aside I'm not too optimistic about the EM Drive, it seems to have had a reasonable amount of time and attention and some amount of money and doesn't feel like it is really getting anywhere. Be great if I was wrong on that last count but hopefully that will become clearer either way.

Meanwhile the Mach Effect works feels more solid. The work was derived from a theoretical basis, that basis seems to be repeatable using other methods of getting there and the experiments seem to have been done increasingly carefully over the years. You can view the experiments as a way of validating theoretical predictions rather than an attempt to create a drive, though that wasn't the original intention. I'm not an expert in any of this but for all the press attention the EM Drive gets I would say the ME approach seems the more likely bet - long odds as it too may be.

Fingers crossed, I would love to see some new drive tech!

Well, China, lets see some pics of the test article in space and some formal reporting please. While they may have it, they may also be lying. Wouldn't be the first time.

I hate those click-bait articles. I can't find any sources to back up what they're peddling and the claims keep getting more grandiose. Sites like the ibtimes and nextbigfuture like to throw everything at the wall in hopes that one of them sticks. The pay off is that they can say they were first on the off chance one of the articles turns out true.

Watching all the SSI videos may prove informative. I've not done this yet but it should be interesting. Anyone done this and care to offer some conclusions?

I still want to see an audit of current satellites. If Shawyer got his ideas from seeing thrust on satellite antennae, anyone can run the numbers and find the trend.

Welp, things might be about to get even more interesting this weekend...

It seems that the CNSA acknowledgment of EMD on orbit was not in that press release but was instead at a press conference that happened some time after the release.

I've found no links to the PR event itself.

This press conference apparently had both an announcement of ongoing tests on the Tiangong 2 station and the followup fluff by the Chinese sat rep.

And now TT sez that the CNSA EMD team lead will speak at an electric propulsion conference in China this weekend... and the subject might be positive on-orbit test results.

That "CN" label is confusing me, keeps making me think Canada, though I know that's wrong. In China all the armed forces are under the People's Liberation Army, so everything has that in the acronym, and so things are weird. Don't recall what they call their space people.

I can Google too, probably should have a bit sooner. It's the "Chinese National Space Administration." Apparently they do have a civilian program, I was under a bit of an impression the PLA had a bit more to do with it, at least officially.

The daylight is uncomfortably bright for eyes so long in the dark.
