00:00While people here are working hard to develop a reusable system, they've designed an essential
00:06part of the architecture in such a way that it has to be thrown away and rebuilt.
00:13The part is called the cargo module, but in fact it's also a propulsion or service module.
00:19So here you're throwing away more than just a cargo module, which sounds like an empty
00:25shell.
00:26So I ask you, is your car really reusable?
00:29If after every drive your engine bursts into flames and you have to replace it?
00:35Exactly.
00:36I 3D printed the Dream Chaser and the cargo module to give you a sense of how the two compare
00:45in size.
00:46The cargo module makes up about a third of the size and it contains the propulsion system.
00:52It's true that Sierra Space is quite an innovative company.
00:55But you can tell that the company comes from the ranks of the established defense contractors,
01:01where short term profits are a big priority.
01:03I would say they are the perfect hybrid of the two worlds.
01:09And that's the main thing that I received.
01:13And that's the main thing that I would say.
