I’ve not done anything here for too long… Busy with paid work, and research into obscure Soviet Space programs.
But on the subject, I did set up a Substack where I have posted quite a few articles on that very subject. You can find the Soviet Space Substack here:
https://graphicsnickstevens.substack.com

Where it has loads of information on recently declassified information, primarily from the RGANTD State Archive.
Most recent are two articles on the Glushko 1987 proposal for a crewed mission to Mars on a monster 200m long Nuclear Electric vehicle, which would require no less than 5 Energia launches.
You can find Part 1 here:

And Part 2 here:

And a whole lot more! As it’s a substack you can receive new posts by email if you wish, and the whole thing is 100% free.
