makayla: that's my dad. and that's me. tiny me.unate circumstances that caused it to happen. but it was necessary for them to come live with us. there were some changes, obviously, because, you know, i'm a lot older, my kids are grown up, and now i'm basically having children again. but i can't imagine my life without her. without any of 'em. woman: and so, speaking of space, what have you got over here? man: okay, so this bad boy is called spheres. the story behind spheres was, uh, a professor at mit had one of his senior projects, uh, and he showed the clip "a new hope," of luke practicing with the little droid floating around. and he said, "i want you to make me one of those." and that's-- that's what they did. (groans) (laughs) man: you already have these things in the space station. here's a sphere. man: so all you have to do is just reprogram it to do whatever you-- you want. these things are able to validate and verify a lot of algorithms and ideas and new sensors that they can maybe implement on larger spacecraft. your obje

makayla: for our strategy, we decided to stick with our assembly zone. i'm excited because... if we can win california, we can watch the competition live at the space station. if this one docks with the second item and doesn't keep dropping it, we should be good. now the question is, does it dock and drop, dock and drop, and if it-- yeah, this is the real question. (children exclaiming) advik: we're losing .2 points every other second. -let me get my... -we have to survive. it reads the code once per second, so this region says, "okay, if item zero is in the zone." yes, item zero is in the zone, and i have item zero, and i drop it. and then it goes back and reads this again. is item one in the zone? yes. does nobody have item zero? yes. so it'll dock it again. -he's right. -this is very hard. it's this part of the code that's broken right now. take the counter out. so this part works without the... -can i throw this away? -yeah, kill the counter. yes. bye, counter. location. item zero docking location. i'm going to have to put the drop item and then take

makayla: teamwork causes all these colossal things just like the first people on the moon.y were a team. they worked together. to do that, it's just... it's amazing. tanner: they continue to inspire me. and that's where the-- that's where the rewards are. that's what makes it all worth it. and space being the vehicle for the kids to dream... i'm all for it.
