Kind: captions Language: en After more than two weeks conducting experiments in [music] orbit, Space Shuttle Colombia disintegrates on re-entry, killing [music] all seven crew members. Those are my friends. [music] You know, I knew them personally. I knew them professionally. Some of them were in my class. I miss them every day. It caused us to lose seven very incredible people. And believe me, they were incredible. >> This is amazing. It's really getting really bright out there. >> Yep. >> Yeah. You definitely don't want to be outside now. The Columbia disaster, we later found out, [music] was due to foam shedding off of the external tank. During launch, a falling piece of insulating foam struck the shuttle's left wing, damaging the [music] thermal protection tiles designed to shield it from extreme heat during re-entry. And what that did was that allowed a very hot plasma to get inside of the wing and basically melt the inner structure of the spacecraft. >> Test simulations back on the ground reveal the devastating impact of this seemingly small briefcase-siz chunk of foam traveling at high speed.
