Me: Hi, my name is Hirohito Yakimoto. My aquaintances call me Hiro-kun, though if you're reading Funimation's English or French translations of this, they'll have even casual acquaintances refer to me as Yakimo, despite Japanese custom. I'm sixteen in the original Japanese version, but the American version will make everyone 3 years older to get the show past the censorers.
This is my childhood friend I've know since birth, though I won't realize until this show how attractive she is or how much she likes me.

Friend-chan: Hi. *bow* My name is Hoshi Sugara, though I normally wouldn't introduce myself since I'm a shy introvert who is embarrassed by the size of her boobs. I'll serve as the main love interest for Hiro-kun and, despite Japanese custom and the logic of me being introverted, will be referred to as Sugara-chan by everyone under 18.
Hiro: Despite the fact that people from all over Earth live in our colony, and the fact that computers could be used to educate people at a fraction of the cost, we go to a typical Japanese high school (college in the American version). I should also tell you that we live in the asteroid belt on the asteroid Ceres, though I'm not sure why that matters in this kind of anime.
Sugara: Because you aren't a pervert, so the shows creators needed a contrived yet somewhat original way for you to see girls in their underwear or boobs. They chose to do that by the colony and all spaceships only having one locker room which the girls and boys have to share. That means that you can walk in on me when I take a late shower or have to change clothes at an inopportune time. Also, you have to get naked to put on a space suit, apparently.
Hiro: Right. Also, they'll be other girls too, and guys. And the school will send us out on a Space ship, putting us in dangerous situations.
In case you didn't realize it, this is low casual and is meant to make fun of tv tropes, especially in anime.
Episode plots:
Ep 1: Establish characters at Neil Armstrong High School. They are all in Professor McDonald's Stellar Geology class and are leaving on a trip tomorrow to help survey near Mar's North pole where they are hoping to build a water production colony in one of the craters there.
Ep 2: Show up for shuttle, get situated onboard, leave for Mars. At the end of the episode Professor McDonald will collapse.
Ep 3: We find out that McDonald-sensei is diabetic, but forgot to pack insulin. The ship doesn't have any, and can't synthesize it, so he'll be unconscious until we get him to Mars. This will leave a group of hormonally charged teens without adult supervision so that they can get into wacky hijinks.
Ep 10: We arrive at Mars, go into orbit, then take the shuttle down. As soon as the Professor gets insulin he's fine and will have no negative consequences from being in a diabetic coma for a week. He tells us his religion (which has no relationship to any late 20th century religion) forbids genetic manipulation of humans, which is why he didn't get this fixed. He goes to Buzz Aldrin high in Ares city and will remain there, looking over the robots at the North pole until we need to leave. We also start to use the robots to help up there.
Ep 11: Totally unnecessary trip to artificial hot springs. Hijinx ensue.
Ep 12: Something goes wrong at the North Pole and all PCs go up there to stay in a habitat meant for 4 people. Surely nothing will go wrong when we have to share four beds and one bathroom, right?
Ep 13: Action for the Shonen fans. We discover that eco-terrorists are destroying equipment so that we can't radio-sterilize the lifeforms they found in the ice. Eventually we will discover them in other locations, getting rid of the moral dilemma, since the show can't have that.
