Yes yes yes. I would go. Im not afraid of no aliens there no different than mingle 2 men. Haha. Let the adventure begin.

Yes and if by myself, a bigger YES.
But I would do it alien ship or no alien ship.
I would also do a one way trip to another star (automated ship).

I find the oceans fascinating.
The mysteries of the deep.
I have spend hours looking at bathymetry maps and love videos which drain the oceans.
So much to explore!

As for the "alien ship"...
Not much lure for me.
The keyword there is "alien" and if it is alien it is from a civilization not from Earth. Most of everything I see will also be "alien" and I wouldn't have a clue as to what it is or what it does. May not even see it as something significant.
When showing alien in movies, there's too many assumptions made. This is because if it is truly depicted as alien the audience won't be able to identify with it. Much of the filming is dedicated to teaching the audience what it is and what it does. This is why I like the strangest stuff in alien movies. The stuff nobody understands.

For instance,
Most movie alien ships have a control room with control panels. Lights and levers and buttons and gizmos.
Truly alien may not have this.
It may be a bio-mental interface with the ship controlled by the will of the alien with no readouts, lights buttons or gizmos, just a room with blank walls. It could be there is no walls or floor, just a series of spheres which the alien passes thru by phasing.

Then there is scale. Ever see the movie *batteries not included? What if the ship you find is a colony ship filled with tiny compartments holding microscopic residents in microscopic habitats?

Since alien is unknown, if its alien, we will have no idea what it is or does. We may have difficulty even identifying anything significant.

I love this! You're awesome rosie and a very dear friend
