(CNN)If we make it to Mars, we are not heading to be in a position to bring everything humankind demands to stay for an extended interval of time — or to construct colonies on the red planet.

In get to build shelters and manufacture instruments, astronauts may perhaps only want to convey a single important component — with minerals in the lifeless Martian soil ready to do the relaxation, a new analyze released Wednesday claimed.
The critical component is chitin — a fibrous substance that is a element of cell partitions in fungi, the exoskeletons of crustaceans and insects, and the scales of fish and amphibians.
Chitincould be mixed with surface area soil by early Martian settlers to manufacture a new material with no exclusive tools and working with minor electricity, scientists from the Singapore College of Technologies and Design stated.
The chitin for use on Mars, the study explained, could come from insects. Offered their substantial protein content, insects could kind part of the diet program for a crewed mission. The authors reported that the extraction of chitin would be a byproduct of the crew’s meals offer and use.
To test their idea, the experts mixed chitosan, an natural and organic polymer designed from shrimp, and a mineral created to mimic the qualities of Martian soil.
The producing procedure applied drinking water and some essential chemistry. The water, the examine reported, could be acquired from subsurface ice on Mars. Sodium hydroxide could be created from Martian soil. And acetic acid could be designed from fermentation of microorganisms — such as food items waste.
“It feels like concrete but significantly lighter. Quite mild rock,” claimed Javier Fernandez, an assistant professor at SUTD and coauthor of the analyze that posted in the journal PLOS A single.
The researchers then utilised the materials to construct a wrench and a design of a Martian habitat, which they said shown the content could empower the fast manufacturing of objects such as basic applications and rigid shelters.
The wrench the experts manufactured wasn’t as robust as a single created from steel, but Fernandez mentioned it met NASA’s standards for “non-significant place purposes.”
Fernandez described the study as a proof of idea. The team failed to exam the things in circumstances that mimicked Mars’ chilly and dry atmosphere.
“We have a route to … producing structures to applications from 3D printing to mold casting with just 1 one material.”
