TL;DR – A fun trip down memory lane, while learning a thing or two about the International Space Station.

Review –
The Magic School Bus was one of those shows that I can’t help but think back fondly on. Like I can still remember an episode where they went inside a decaying log for some reason. So when a new episode of the show popped up in my feed, and one set in space no less, I had to check it out, and I got sent back in time and into the future all at once.
So to set the scene, we skip all the standard preamble and start with the Bus as a rocket blasting off into space. Ms Frizzle (Kate McKinnon) is taking the whole group up to the International Space Station. The astronauts are heading back to Earth, so the team is watching over the station until the next crew arrives the following day.
