Food Acceptability: The crew completed a Food Acceptability Survey using the Data Collection Tool on an SSC (Station Support Computer). This investigation seeks to determine the impact of repetitive consumption of food currently available from the spaceflight food system. Results will be used in developing strategies to improve food system composition to support crew health and performance on long duration missions.

ISS HAM pass: The crew participated in an ISS HAM pass with Maple Dale Elementary School, Cincinnati, OH. Some of the questions asked the crew what things are easy on Earth but difficult in space, how things like planets are dodged in space, and what happens if a crewmember is allergic to something arriving on a supply ship. ISS Ham Radio provides opportunities to engage and educate students, teachers, parents and other members of the community in science, technology, engineering and math by providing a means to communicate between astronauts and the ground HAM radio units.

OsteoOmics: The crew performed a media exchange for day 1 of the first session of the OsteoOmics investigation. The activities went smoothly and were completed ahead of schedule. A previous version of OsteoOmics was performed several years ago and was very successful – the current experiment expands on those successes. Millions of Americans experience bone loss, which results from disease or the reduced effects of gravity that can occur in bed-ridden patients. OsteoOmics tests whether magnetic levitation accurately simulates the free-fall conditions of microgravity by comparing genetic expression osteoblastic cells, a type of bone cell, levitated in a high-field superconducting magnet with cells flown in low-Earth orbit. This information helps scientists determine the molecular and metabolic changes that take place in magnetic levitation and real microgravity.

Systems:

Emergency Simulation OBT: Today, the crew participated in a training exercise for ISS fire and rapid depressurization emergency scenarios. The emergency training consisted of:

Crew and ground controllers utilizing simulator data to identify each of the emergency scenarios and executing the appropriate response procedure(s).

The crew physically translating through ISS to the appropriate response locations to visualize the use of equipment and interfaces.

Practicing communication and coordination with the mission control centers in Houston and Moscow for the each of the scenarios.

A post-simulation crew conference to discuss/evaluate the crew/ground control responses during the training event.
