OsteoOmics: The crew changed BioCell media in BioCell Habitat 2. The media in the other four habitats will be changed this week. This is the second of four weeks of OsteoOmics operations. Crewmembers experience bone loss in orbit, stemming from the lack of gravity acting on their bones. OsteoOmics investigates the molecular mechanisms that dictate this bone loss by examining osteoblasts, which form bone, and osteoclasts, which dissolve bone. Improved understanding of these mechanisms could lead to more effective countermeasures to prevent bone loss during space missions and in a wide range of disorders on Earth. This may lead to better preventative care or therapeutic treatments for people suffering bone loss as a result of bone diseases like osteopenia and osteoporosis, or for patients on prolonged bed rest. Veg-03: The crew harvested leaves from Chinese Cabbage growing in the Veggie facility and inserted samples into Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). The remainder of the plants were left to grow. The goal of Veg-03 is to further demonstrate the proof of concept for the Veggie plant growth chamber and planting pillows. Future long-duration missions into the solar system will require a fresh food supply to supplement crew diets, which entails growing crops in space. Previous investigations focused on improving productivity in controlled environments but the limited quarters of the space shuttle and ISS made it difficult to conduct large-scale crop production tests. Veg-03 expands on previous validation tests of the Veggie hardware to grow cabbage, lettuce and other fresh vegetables. Tests determine which types of microorganisms are present in space-grown cabbage, providing baseline data for future crop-growing efforts. Behavioral health surveys assess the impact of growing plants on crew morale and mood. Extravehicular Activity (EVA) Preparations: The crew completed the following in preparation for the EXPRESS Pallet Controller Assembly (ExPCA) EVA currently planned for this Friday, May 12. Prepared the Equipment Lock, Extravehicular Mobility Units (EMUs) and ancillary hardware to support suit donning. Installed/replaced Metal Oxide (METOX) Lithium Hydroxide (LiOH) canisters and batteries in EMU 3006 and 3008. Performed EMU pressurized fit verification to ensure proper fit and feel prior to the EVA. Performed a procedures review covering reminders, emergency briefing and helpful tips. Following the review, the crew completed a conference with ground teams to address any questions or concerns. Orbital ATK (OA)-7 Cargo Operations: Yesterday afternoon, the crew continued transferring Cygnus cargo to ISS. Approximately 3 hours of transfer operations remain to be completed. Cygnus is currently scheduled to unberth from ISS on July 16th. Today’s Planned Activities All activities were completed unless otherwise noted.
