Astrobot

Titan

C31-35-t3 to the Earth. I am reporting from Titan the moon of Saturn. There's -290 degrees Celsius or -179 degrees Fahrenheit, not habitable for humans, also no breathable oxygen is here. The land is made out of sand which is more coarse than sand on Earth or Mars. The atmosphere here is similar to Earth but the surface pressure is 50% higher. Wait something next to me just exploded. Oh. I think it's Cryovolcano. It erupts methane, ammonia or water into the environment below the freezing point.
"Please do not scare me like that next time."
I'm sorry Ms Wilson. I'll try to be more careful.
"Astrobot don't forget why you came there"
Yes. I should get the drill you gave me.

"Sir I gave C31-35-t3 command to drill into an ice and search for life under water."
"He can swim?"
" Yes she has installed fins. I am telling you, don't doubt her. She's the right one for this mission."
"So far every information it gave us was something we already know. Even on the way to Titan it was only observed the surrendings. It did not gave us any information which we didn't know."
"C31-35-t3 may not be the best model for sending new data but it was build to last up in difficult environment. "It "observes things and thanks to that we can find new information about different subjects."
"So far nothing new Ms Wilson"

It's dark in here. I will use light.
"No that's not a good idea! You might disturb potential life or attract something dangerous to you. Use night vision instead."
Why do I have light when I can use dark vision instead?
"For better quality of pictures."
But if I photograph potential life with light couldn't I disturb it?
"Yes good point. At least you don't scare it like this use the night vision instead."
Okey. Turning on night vision. Nothing so far. Looks like I am alone
"Don't give up Astrobot. There doesn't have to be many visible creatures it's more likely that there will be little creature harder to find. Besides you're not on a bottom yet it's possible that life will be most likely there."
Alright if you say so. I want to ask. Why do you call me Astrobot? My name is C31-35-t3.
"Oh- you don't like it?"
No it's just. I don't understand. It is not my name so I want to know why.
"Well you see us humans like to give each other nicknames. It's usually used by someone who is close to you like friend for example. Since we talk alot I thought calling C31-35-t3 was too long and complicated to say. So I gave you nickname. Astro because you travel outside the Earth's atmosphere and bot because you're robot."
Like astronaut but robot.
"Yes. Do you like it?"
I don't really care so I don't mind. Do you have a nickname?
"It's Cassie."
Cassie-... Can I call you that?
"Of course you can."
