00:00I don't think people realize is that this is a national laboratory.
00:12If you look around, you know, on the walls and every one of these bays, there's another
00:17experiment essentially or a systems rack that actually keeps the space station operating.
00:22This place is incredible.
00:24We've had astronauts living and working on the space station for over 22 years of continuance
00:29presence at this point, and it's really an honor to get to continue that tradition.
00:35Thank you very much for all your help this morning.
00:37Thank you for all your help today, and I'm excited to learn more about what we're printing
00:42here and see how it goes.
00:46For the last two months, I've been working on a lot of experiments, and I recall working
00:51on heart tissues.
00:52I saw some heart tissues beating in space, and it was incredible.
00:56These tissues are receiving medication on board the station, and this can help us develop
01:01some medication for heart diseases on Earth.
01:05So Tom, we see that top one beating.
01:08Yeah, it looks like happy heart cells.
01:12Every day is truly unique and different.
01:15We could be doing anything from spending all day in a glove box working on science experiments
01:20to doing science on ourselves.
01:22And this is not a fashion statement.
01:23This is actually part of the science we do up here.
01:26I actually have a whole suit with a suite of tools that are measuring part of my biometrics.
01:33So we are our own experiments as well.
01:36This is actually a cylindrically shaped airlock that we have the capability to put small payloads
01:42inside of and send them out to space.
01:44So this is our launcher that deploys these small satellites.
01:47There's a spring in the back, and that provides the force to launch the satellites.
01:53The space shuttle is the first space shuttle to go into orbit.
01:58It is the first space shuttle to go into orbit.
02:01I think humanity has an innate desire to explore.
02:06This is one big part of our constant exploration as humanity.
