Overall this is a good concept for a storyline. I think if you took the time to pick it back up and polish it a bit, (i.e. make it read like someone other than a sixth/seventh grader wrote it,) it would turn out to be an excellent story.

A few points:
The name of a ship is always italicized.
The cursing makes the story more realistic, but it is highly unlikely that one person would cuss the exact same way twice in the same chapter.

P.S. I really liked the Chinese script!

(KEEP AT IT! Practice is the key. Trust me, I've been doing this a while.)

Some constructive critisism first.
It is never said where the ship and its crew take off from, the moon? Mars? Earth? It would help because then the readers would know that when they have to land on Earth for repairs if they're just pulling a u-turn or if they were headed in that direction to begin with. (I assumed Earth)
"WHOOSH! I get jammed back into my seat as the antigrav devices turn off and the engines take over."
'Whoosh' isn't a very good descriptive term. Go into a little more detail and describe the feeling and sound of this 'whoosh' it helps put the readers in the seat of the ship itself.
"“Holy crap, those new engines are good,” says Peterson and I nod" A skilled and experienced pilot wouldn't dumb down his speech on something that he is educated in, make it a little more technical, but don't get carried away. "says Peterson and I nod" is sort of a run on sentence, try 'says Peterson. I silently nod in agreement." or simply drop the 'and' then put a comma after Peterson. Then maybe shortly explain why the engines were replaced to begin with, were they old and outdated? were they damaged in a battle?
" I certainly am lucky, I’m only sixteen and I already pilot my own cargo ship with two copilots under my command.." To be so young and be trusted with the responsibility of not only commanding a ship, but owning one as well would require him to be extremly skilled and gifted and it sort of clashes with his inability to quickly come up with a plan when the 'meteor' hits them. Which brings me to you calling it a meteorite, it is only a meteorite when it has crashed on the surface of a planet, a meteor is the flash of light given off at night when a chunk of interplanetary debris burns up in the atmosphere, and that chunk of debris is called a meteoroid, which is usually very small in size, less than a kilometer. larger chunks of interplanetary debris are called asteroids, but those lay far beyond Mars in the asteroid belt and rarely wander far. It may seem I'm getting a little carried away with my review, but that's only because I enjoyed this story, stories I don't care for I don't bother writing a review.
"Evalrous wrestles with the controls as if they were some sort of cloned wild beast like a bear with human and wolf genes..." The type of wild beast is not really important, and the analogy is sort of drawn out. I like the combination though, something you would see on Ripley's Believe it or not.
"Repair robots are basically two-foot tall spherical discs..." A sphere is a three dimensional ball, whereas a disc is a flat circular object, it's kind impossible for these robots to be both. Unless of course these disc robots can 'inflate' into a sphere.
"“…You’re kidding, right…you aren’t…Oh crap… how did he die?”" A fellow pilot and most likely a fellow friend has just died, there should be a little more emotion than just "oh crap, he died?" try and put yourself in his shoes, how would you feel if a friend of yours died engulfed in flames? Now put that emotion down in words.
I truly enjoyed this story thusfar, one of the few that I was able to read beyond the first chapter, keep it up.

yo it totalee suks hahahahahhaahahahahahhaahaghhaghahghahghahhahaha
i puked on itmwahaahgahaghagaggagahaga
it stinks

...
Wow. Or in spanish, Guau.
You say you're still in middle school? I have to say I'm impressed. I find it interesting that you live in Seattle... I'm in Spokane, on the other side of the state. But I digress. You wield descriptive and narrative devices well, I'll give you that. You seem to have a clear visualization of that yoe describing, and that's sometimes hard to come by.

I'm looking forward to seeing this in Barnes and Noble...

This is awesome! I love it!1

Wow, pretty good Julian.

Wow, Julian!! That's actually pretty good
I'm suprised. :D
