“Current day technology” is sort of poorly defined because you can make new technology in one day. “Current tech” is a fake constraint, because even preparing for a launch in two years, you’d be developing new technology all along the way.
The annoying thing is that we could’ve been simulating long duration partial gravity using artificial gravity for decades, but NASA has refused to do so. For inexplicable reasons. If I had to guess, it’s due to the microgravity research community fiefdoms who have made a career of microgravity health effects and so don’t like the idea of directly addressing them using artificial gravity as it makes a whole career’s worth of work largely obsolete.
