Dude, did you read what I posted? He claims the relay satellite would have 1/300th the mass of a solar power satellite.
That won't matter (see below). Besides, it's likely that Criswell was being overly optimistic about the focusing abilities of the masers on the Moon; if the microwave beam spreads more than he thinks it will, the mirror orbiting Earth will have to be far larger (quadratic scaling) and therefore far more massive than he thinks.


Also, what makes you think bringing the satellites from the Moon would be that much cheaper? What you are talking about would require a massive lunar transportation industry. You would need to lift hugely massive solar power satellites from the Moon and carry them all the way to Earth orbit. Which would not be cheap.
As I have said, if the propellants come from Phobos they will be almost free. If the SPS's solar panels and the rockets launching them are made from lunar substances, the cost will be lower than creating a massive solar farm on the Moon (imagine all the highways that will have to be built). Especially if we use robots to assemble the SPS in GEO; it's difficult to imagine robots coping with the complex environment of the lunar surface (anytime soon).

In light of recent successes from our manned aerospace program, I wanted to share the link for Fiyta, the official watch sponsor for the shenzhou program. You can buy official chinese spacewatches from them.

Seems much more befitting of our time than some omega speedmaster, for which we have no connection or relevance. I'm probably ordering one myself in the next few months. They also have a J-20 inspired watch (Mach collection) for those who are interested. Remember these are official authorized products.

Informative video on CSS's robotic arm, subtitle in both English and Chinese. It has a really interesting section on exactly how the arm attaches firmly to the target adapters.

Supposedly the arm has already walked from the narrow end of the station (configuration at launch) to the fat end prior to Shenzhou-12's arrival. The control being from the ground.
