This first video is of the monarch caterpillars in their little space container. 2 of the caterpillars are supposedly getting ready to shed, so they're not moving around much.
The second video is of painted lady caterpillars that are also on this space mission. I didn't realize there were other caterpillars going up besides the monarchs. This video was kind of sad for me to watch, because the squirmy caterpillar in the middle is actually trying to shed its skin, and it can't seem to manage it in micro gravity. We'll find out tomorrow if it survived.
I guess they shed their skins OK. I found this brief video update on YouTube that points out the molts.
