According to foreign media reports, NASA and other space agencies are already making plans for the inevitable Mars exploration. This means that the red planet needs to send manned spacecraft, carry out research and open up new horizons there. The journey is undoubtedly long, but it makes sense to send people to the surface of Mars and let them live comfortably on Mars, and that means building on the red planet. However, a mission to Mars is already a challenging task, and with the addition of human passengers, it is even more challenging. Life support systems, food and water are needed throughout the journey, and even if the water is recycled and travelers can grow their own food during the journey, a lot of extra equipment is needed. < / P > < p > because the storage space of spacecraft to Mars will be very expensive, this means that there will be no space to carry items such as traditional building materials. While researchers have come up with many solutions – including building houses in ancient lava tubes on the surface of Mars – researchers at Singapore University of technology and design have come up with a slightly different solution. < / P > < p > in a new study published in PLoS One, researchers explain how the first Mars travelers used chitin to build houses and other objects. Chitin is found in nature and forms the hard shell of crabs and the hard exoskeletons of beetles and other insects. Integration is a very versatile material, and it may be the key to making life on Mars easier. < / P > < p > although there are no crabs or insects on Mars, it is still possible for humans to use Martian soil and mix it with the material carried on the journey to create substances similar to chitin. Chitosan, a fiber that gives chitin rigidity, combines with Martian soil simulants and can be easily handled with minimal equipment. The result is a solid material that can be used to make tools and even to support building structures.
