Researchers at the Ballistics Impact Lab utilize a 40-foot-long weapon to imitate what it would resemble to be hit by a micrometeorite in area. Just recently, the team has concentrated on testing different kinds of material for usage in area fits. A fast decompression from a micrometeorite strike anywhere on a match would be deadly to any astronaut unlucky enough to suffer one..

Understanding how a piece of fabric would stop working in such a scenario is vital to improving its style. Some types of failure are even worse than others. The lab has a series of high-speed electronic cameras and sensors surrounding the product under test to ensure it can capture as much data about those failure modes as possible..
Those failure modes can be caused by more than simply steel balls. A different test rig shoots a piece of simulated moon rock (mainly made of basalt) vertically down onto the fabric. The material isnt the only product that has to undergo such testing– other material that might be utilized on the outside of environments, or even material specifically designed to capture area debris, should likewise go through comparable violent screening.

Such screening will continue, using a mix of resources from the Glenn Research Center, where the physical laboratory lies, and Johnson Space Center, where the information is examined. As keeping a tight seal between the external void and the soft human occupying the fits and environments of the Moon ends up being more vital, violently testing the materials that make those seals out of does so.

Instead of simply dropping the item under test, as is typical in most settings, they shoot it with a steel ball going 3000 ft/second.
