Elasztáns

Elasztáns is a fictional material described in the science fiction novel "The Martian" by Andy Weir. In the story, it is a crucial component used by astronaut Mark Watney to repair a damaged habitat module on Mars. Elasztáns is depicted as a highly flexible and durable synthetic polymer, capable of withstanding extreme environmental conditions, including the low temperatures and thin atmosphere of Mars. Its primary function in the narrative is to create an airtight seal, preventing the loss of breathable air from the habitat.

The material is described as being strong enough to withstand significant pressure differences while remaining pliable. Watney uses it to patch a breach in the habitat's environmental control system, effectively saving his life. Elasztáns is not a real-world material but rather a plot device created by Weir to solve a critical survival challenge faced by the protagonist. Its properties are exaggerated for narrative effect, emphasizing its resilience and adaptability in a hostile extraterrestrial environment. The development and application of Elasztáns highlight the ingenuity and problem-solving required for long-duration space missions.
