##$\ \ \ F = \dot{m}_e V_e - \dot{m}_0 V_0 + (p_e - p_0) A_e$
versus
##$\ \ \ F = \dot{m}_\mathrm e V_\mathrm e - \dot{m}_0 V_0 + (p_\mathrm e - p_0) A_\mathrm e$
@PearsonArtPhoto now the fourth edit, even you have been corrected!

The NASA Glen Research Center tutorial page Rocket Thrust Equation links to the General Thrust Equation page which starts with: Which transcribes into MathJax as: $\ \ \ F = \dot{m}_\mathrm e V_\mathrm e - \dot{m}_0 V_0 + (p_\mathrm e - p_0) A_\mathrm e$ where $\mathrm e$ and $0$ indica...

I'm guessing that this equation is so fundamental, and people are so fond of it, that it is given a higher than average amount of TLC.

I'm corrected all the time, it's part of the learning process.

thought I can't figure out if it's Yes or No.

Apparently, BepiColombo and JAXA’s Mercury Magnetospheric Orbiter have good taste!

I've heard of the artificial moon, which is definitely a strange concept.
I pretty much figured what Scott said, but it was nice to hear the math.

From 17-Oct-2018 NASA ICE tweet: I'm curious of the actual dimensions, and if possible a complete photo. And curious in a scifi sort of way if they have a ratio of 1:4:9 From yesterday's #IceBridge flight: A tabular iceberg can be seen on the right, floating among sea ice just off of the Lar...

@PearsonArtPhoto I found it hard to concentrate on that particular video of his. He says a lot of words in a short time as background, but I can't figure out what his point is. It's like he just wanted to get a blurb out there as quickly as possible.
Did he ever get to a firm "yes" or "no"?

You could, but it would be a bit crazy.
And the version they are stating wouldn't work.

ah, then no earthshaking surprises there

You would need a large mirror, but that mirror would move with time, making it difficult to keep working.

oh, station-keeping against solar pressure. They may have a clever way to manage that but it never made it into the English press (or even in Chinese). Or not.

The satellite test they are using is a LEO test, so pretty much impossible to do anything useful with.

A "bright and glorious future!"
