The answer: Yes, but it’s not quite finished.

One enters the rocket by clicking on the command module, almost at the top of the Saturn V. The huge vehicle launches at 32 minutes past the hour, every hour, with the tower’s gantry retracting just a few minutes before. If you’re outside, it’s a spectacular sight as the great behemoth launches into the air. If you’re inside the rocket, you’re in for quite a ride.
I had the fortune of speaking to one of the people responsible for the sim, Rocket Sellers. “I was just mitigating some space debris here,” he told me, “impromptu erotic photo studio in the sky. ... I’m the owner of record here, and there’s a crew with cleaning powers. I try to clean politely so they do not reincarnate as pesky griefers.”
Asking about the Moon rocket, “It’s still a work in progress. This is Version Two. Wicked Quasimodo had an earlier build, but Havoc 4 broke it. This one is lower prim, and the lunar module is sculpty. It really should be on NASA property, but there’s no NASA region that will adopt it. He first tried on the NASA CoLab Testbed, but the sim was just too lagy, and there was just too much junk in the sky. So he began working on it here, with the idea it would find a home at NASA for the Apollo 11 Anniversary. Instead, NASA put some posters around with landmarks to here.”

Rocket Sellers invited me to go along for a ride on the Saturn V, and so we and one other person got aboard the command module. And at 32 past the hour, the rocket roared and thundered up into the air. The ride is best seen with Environment set to Midnight, and being a Second Life spaceship, the stages shake a little as it travels upward. Eventually, the first stage falls away, and then the second. Soon, the ship comes to orbit a megaprim Earth, “It’s very beautiful from up here” “Approaching New Guinea.”

Eventually, the faring on the last rocket stage separated, and the Lunar Module, folded up, appeared. The Command/Service Module then rotated, and connected to it. Passengers could then right-click to board it. The connected ships then went into Lunar orbit. Unfortunately, the ride did not progress any further. It had yet to be finished.
Despite this and the tiny flaws, this reporter, can only consider it a great and memorable build, especially if one is a space fan, or otherwise nostalgic for these glory days of the manned space program.
The Space Frontier Saturn V Moon Rocket is at Space Frontier (154, 126, 137).
