I like how everybody went from N1 being retired to continued flight to another Zarya station, to manned flybys of other planets, which is still expensive and pushing Soviet willingness far. Now we are talking orbital missions and possible landings on the Martian moons
A Venus flyby is relatively useless, same with orbital missions, the clouds block the land so it would be photos of clouds, and nothing would be learned besides stuff probes already know. Mars is kinda the same unless landings are involved (Mars or its moons)
The Soviets are dealing with huge economic instability due to Gorbachev's reforms, and space is not a focus, in OTL the soviet space program was slowing down by the late 8ps, and that was just with Buran-Energia and MIR with Soyuz and Progress flights. ITTL the Soviets have an active lunar program and monster LEO vehicles like TKS with rockets like Groza (N1) flying lunar and shuttle missions.
If anything ITTL Soviet space will start to slip considering the last post was in 1987, i can see the Soviets barely keeping their moonbase active and possibly a small LEO station. But flights to other worlds will not have the funding or priority until the Union recovers, or in the case of a full collapse like OTL, never have priority
A flyby would require a commitment of at least 3 N1 launches and severe modifications for all parts involved, like fuel storage for a year without boiloff, a stronger reentry capsule, and radiation protection and backups for the manned habitation component.
An orbital mission would likely mean 4 or 5 N1 launches, same modifications as above but more fuel.
A Mars orbital mission WITH landings on the moons would need at least 6 if not 7 N1 launches, the habitation and reentry capsule, along with the fuel for injection, braking, Earth return burn and slowdown at Earth, plus the lander for the moons and the fuel required for orbital transfers between orbits
With the economic slowdown of the Soviet Union occurring, this would mean 1 to 2 years of N1 flights would be dedicated to a one-time publicity stunt, development time would mean a mission date no earlier than 1993, which would be affected by the economic issues
And don't forget the elephant in the room, if your going through the trouble of sending PEOPLE to Mars orbit, why not land on the surface? Landing on Mars's moons would be impressive but lets be realistic, its nothing compared to landing on MARS itself. Which would make history and really fuck with the americans. Though it would be hilarious if it somehow overlapped with a US Freedom mission to the moon "Americans return to the moon, Soviets at Mars" would be hilarious
Been reading Fear, loathing and Gumbo on the Campaign Trail 72, i wonder if the Soviets could still pull off the concept of MBA Communism (Like China), the issue would be finding a legit replacement for Gorbachev who had these thoughts in OTL
