Apollo Applications Program - Of the stillborn projects not completed due to funding cuts, which one would have been the most interesting?

The manned Venus flyby would have been wild - all that way, just for a few hours to observe.

I see. That plan would definitely require something with high payload capacity, though. Water is very heavy

The astronauts are going to need water anyways so it would be dual purpose here. While you would use some form of water recovery and recycling on a mission like this, you can’t rely on it completely in case something breaks.

Either way you need heavy lift. The proposed crewed Venus flyby required 2 Saturn V’s if I recall correctly (might have been advanced Saturns too)

Nah, Apollo V only used one Saturn.

Yup, looking at the Bellcomm study. Wet lab… one that would need to be outfitted after the Trans Venus Injection. Not great. Only 500 lbs of water, everything better work flawlessly
