The Expedition 53 crew worked on a variety of astronomy gear today that looks at meteors in Earth orbit and harmful radiation from deep space. The crew also explored how microgravity affects human bones and muscles.
Flight Engineer Mark Vande Hei worked on a camera for the Meteor experiment, ongoing since March 2016, which peers out of a specialized window in the Destiny laboratory module. The camera observes meteors and meteor showers and analyzes the imagery to determine their physical and chemical composition.

Flight Engineer Joe Acaba installed the Fast Neutron Spectrometer in the Unity module today to explore a new technique that measures deep space radiation. The new technology may be used to provide a more accurate assessment of the mixed radiation future crews and spacecraft may be exposed to.
Cosmonaut Sergey Ryazanskiy strapped himself into the Muscle Atrophy Research and Exercise System (MARES) chair today for a look at his calf muscle and tendons. Flight Engineer Paolo Nespoli assisted Ryazanskiy into the MARES chair and Commander Randy Bresnik collected ultrasound imagery of his leg. The data is being collected for the Sarcolab-3 experiment that is observing space-induced chemical and structural changes in muscle fibers.
