00:30The biggest challenge we faced is to make the material in the environment of near vacuum and very cold, like
00:40the Martian environment.
00:41So we try to find an analogy between the Martian environment and terrestrial engineering.
00:48So we happen to notice that when people freeze and dry the fruit, the environment is actually very much like
00:56the Martian environment, and it makes the material hotter.
01:00And that's because the phase change just takes away the moisture in the fruit.
01:05And we find that's pretty inspiring, and we started to go along this path.
01:30So basically we are making a concrete, which is made of the sand, which can be found on site.
01:36And the important recipe is the glue.
01:40So in this glue we have the gelatin sole, which serves as sort of the environment for those yeast to
01:49grow.
01:49And the yeast, the genetic engineered yeast, produce the adhesive proteins to improve the performance of the glue.
01:59So in total we have this very interesting recipe.
02:30I don't see any factors that prevent us, fundamentally prevent us from executing these ideas on Mars.
