Three residents of the International Space Station will take a short ride aboard a Soyuz MS-18 spacecraft Tuesday, Sept. 28, relocating the spacecraft to prepare for the arrival of the next set of station crew members.

Expedition 65 flight engineers Mark Vande Hei of NASA and Oleg Novitskiy and Pyotr Dubrov of the Russian Space Agency Roscosmos will undock from the station's Earth-facing Rassvet module at 8:21 a.m. EDT. They will dock again at the Nauka Multipurpose Laboratory Module at 9 a.m. This will be the first time a spacecraft has attached to the new Nauka module, which arrived at the station in July.

Live coverage of the maneuver will begin at 8 a.m. on NASA Television, the NASA app, and the agency's website.

Shock testing is commonly used throughout engineering to determine how a product will do when impacted by something. That something could be anything from the ground to a cruise missile. Like so much else in space exploration, engineers at NASA are performing the same type of test, just scaled up. Instead of simply dropping the object under test, as is common in most settings, they shoot it with a steel ball going 3000 ft/second.

Researchers at the Ballistics Impact Lab use a 40-foot-long gun to simulate what it would be like to be hit by a micrometeorite in space. Recently, the team has focused on testing different types of fabric for use in space suits. A rapid decompression from a micrometeorite strike anywhere on a suit would be fatal to any astronaut unlucky enough to suffer one.

Understanding how a piece of fabric would fail in such a situation is critical to improving its design. Some forms of failure are worse than others. The lab has a series of high-speed cameras and sensors surrounding the material under test to ensure it can capture as much data about those failure modes as possible.
