My main question is if the Russians can do lunar flybys why haven't they?
These participants would include private individuals, corporate, university and non-profit researchers, lottery winners and journalists. Destinations would include the International Space Station, commercial space stations and orbital free-flys.

then why not do it after Apollo?They would have more capability then us at that point.

I'd still like to understand the business model for this. With two $150M customers, that's $300M. Does Russia expect this upfront, or will they front the money before being "paid back?" Furthermore, is $300M all that is needed, including tests? I doubt it. Therefore, the government will need to front even more cash and hope that additional tourist flights pay it back. Don't get me wrong, I think this is a very exciting concept, but wonder if it is really financially feasible.
I thought it was two tickets for $300 million each. The company might throw in its own money to forward the idea. The hope is to make money on subsequent flights. They think the first two will be losses.

The official line after they lost the moon race was that they were never in a race to start with.QuoteThey would have more capability then us at that point.Zond style flyaround is basically a dead end stunt. Since the collapse of the USSR, the Russians have had more pressing things to spend their money on.
As I recall, the Zond capsules lost pressure and had other issues as well. If they'd sent cosmonauts, likely they'd have had some serious propaganda problems back then, even worse than claiming they were never in the race.

In other words, they worked the bugs out.That was followed by some 40 odd years of Soyuz flights. I suspect that the failures experienced during the 1960s are not relevant today.
The frequency of off-nominal reentries is a severe concern if one wants to attempt reentry from lunar velocities where the margins are a LOT tighter.

IIRC, that was one of the reasons circumlunar Gemini flights were not pursued.
