Write a story where the power goes out on a spaceship or submarine

Finally, after all this time I get to explore space!"

It's been around two years of travel, we are coming back from a mission on Pluto and it took around six months to get there and six months to get back. We got to spend a year researching Pluto's atmosphere and everything around it. I wish we could have stayed for longer but the ship can only hold 2 years worth of power and we have only enough to get back home.

Right now we should be passing by Jupiter and its many moons. I heard one of them has the deepest oceans possible, I wonder what lives there.

I decided to take a nap, it's been a long 32 hours of checking on the haul. We are attempting to bring back some rocks from Pluto but we don't know if they will be too heavy for the ship. But it's nap time!

*Beep beep beep*

"Huh?"

*Beep beep beep*

"What's going on?"

"We're losing power! Quick start the backup generators!"

I get up and bolt to the back, trying desperately to start the backups.

They turn on just enough for us to get a crash landing on one of Jupiter's moons.

We hit some sort of liquid. I think I know which moon we're on...

I yell up to the bridge, "Go submarine mode! I think we're on the deep ocean moon!" As I finish, we start to transform. I watch as the battery drains. Soon the lights turn off and the, now submarine, sinks down into the deep ocean. Its creatures watch as the seemingly small object floats down into the deep.

A few hours later, we settled in a valley. Right next to a trench... we need to be careful about our next move.

We have two choices. Die in here or die out there.
