Offworld Protein Chemistry: ISS Ring Sheared Drop Module

Scientists can study protein solutions without interference from container walls and gravity driven forces present on Earth using the space station’s Ring Sheared Drop module.

The device pins a drop of liquid between two rings and holds it in place with surface tension.

JAXA (Japan Aerospace Exploration Agency) astronaut and Expedition 73 Commander Takuya Onishi sets up for Ring Sheared Drop-IBP-2, a study of the behavior of protein fluids in microgravity.

The investigation uses the module to test computer models to predict fluid behavior that could lead to improved processes for manufacturing pharmaceuticals, 3D printing, food processing, and microelectronics.
