As you may know, the oceans of Europa are sequestered underneath a layer of ice which is probably ten or twenty kilometers thick. This makes them a little tricky to access, especially given the limited resources available to a logistically-feasible lander. So I was intrigued by this article about a highly miniaturized submersible vehicle that wouldn't require much energy to transport and operate and would only need to make a small hole in the ice.

It also infected me with the following earworm:

We'll find life with a tiny submarine, tiny submarine, tiny submarine

On a world that's far away
Little aliens swim in the sea
And we'll find out where they live
With our tiny submarine

We will launch it into space
On a rocket ship that's fast and lean
That will land upon the ice
And deploy our tiny submarine

We'll find life with a tiny submarine, tiny submarine, tiny submarine
We'll find life with a tiny submarine, tiny submarine, tiny submarine

With its heaters on full blast
Our sub is moving down pretty fast
Paying out its fiber line
Through the layers of ice and brine

We'll find life with a tiny submarine, tiny submarine, tiny submarine...

...and so on.

But this sort of thing would benefit hugely from some musical accompaniment. I'm thinking of taking up the ukelele so I can provide it myself rather than depending on my more-musically-skilled friends and family.
