So I don’t remember much about this movie, but I do remember some scenes. The movie is set in space and there’s a kid who’s the protagonist, and his mom has gone missing. He somehow gets to space (idk how, or if they were always on space). While there, he looks for his mom and they find her, but somehow she isn’t wearing a oxygen helmet, so the little boy takes off his helmet and puts it on her, and he blacks out. Then when he wakes up, he sees his mom putting it back on him, and she blacks out. Meanwhile the kid’s friend goes to find another helmet and they manage to rescue the mom (or she dies idk, that part’s pretty vague, but I think she lived).
Some details that are random, but may help are:
They travel through some sort of tubes that suck them up to where they need to go.
The space helmets they wear are really easy to put on. All you have to do is put it over your head and twist the neck area and it will somehow seal and make a pressurized gas noise.
The movie is definitely rated G or PG.
It’s in English, it’s in color, and maybe from the early 2000’s.
If I remember correctly, the kid had dark hair and his friend was an adult and a bit chunky.
