Selections From the Exploration Journal for Planet X

Our mission of scientific discovery continues, and there is something exciting to report. We may have finally found a planet capable of supporting life. The nearby planets were either too hot or too dry to support life, but this planet seems to be different. Its surface is mostly a blue liquid, though it is spotted with some green and brown parts, and some kind of white substance seems to be moving around the planet.

Now we are orbiting the planet. It seems that our assumption was correct! There are a few mechanical devices circling around it and their designs are rather complex. They were certainly made by some kind of intelligent beings. Are these machines part of a monitoring system? Have they signaled our approach? There doesn’t seem to be any threat, so we have decided to ignore them and get closer to the planet. I hope that their inventors are friendly.

Unlike our planet, which is totally covered with the precious liquid that sustains us, the green and brown parts of this planet are too dry to support life. The blue part is mostly H2O in a liquid state. Although it is liquid, it is not quite the same as the liquid on our home planet. Still, we might be able to find life here. At least, according to our equipment, there seems to be something alive down there. We are ready to start direct observation and will soon dive in. I’m so excited that I won’t be able to sleep tonight!

We succeeded in entering this unexplored liquid safely. The scenery around us was very similar to that of our planet, with soft plants gently waving back and forth. We also noticed a variety of thin swimming creatures. How exciting! We have found life on this planet! However, we cannot see any creatures capable of producing an advanced civilization. Without arms, these swimming creatures wouldn’t be able to build complex machines even if they were smart. Are the leaders of this planet hiding from us? Do they have reservations about meeting us? Is that why they use those flying objects to check out space? Hopefully, we will be able to find some answers.

DAY 12
We found a big object lying on the bottom. Its long body looked somewhat like our spaceship. It sat silently looking very old and damaged. Apparently, it isn’t being used anymore. Maybe it is a part of the remains of this planet’s ancient civilization.

DAY 19
Since we started our dive, we have seen many more unusual creatures. We were especially surprised to find one that looked very similar to us. The upper part of its body was round and soft. Underneath that were two large eyes and several long arms. It escaped quickly, leaving a cloud of black substance. We don’t know if it is the most intelligent life on this planet, but our expectations for new discoveries continue to grow.

DAY 39
This part of our investigation will soon come to an end. We have found more remains and abandoned objects like the one we found earlier, but there have been no signs of the creatures who made them. Perhaps the leaders of this planet have died out. Anyway, we found life on this planet, which is a very big discovery. We must leave this planet for now, but we will certainly come back someday to continue our research. We will return home with amazing reports.

DAY 40
We silently floated up to the surface and then into the air. Just as we were leaving the planet, we saw a lot of strange creatures on the dry areas. What a shock! We, creatures living in liquid, had never imagined creatures like them! Floating safely in our ship’s liquid, we realized that our common sense had led us to the wrong conclusion.
