NASA International Space Station On-Orbit Status 28 December 2016

A U.S. spacesuits is seen attached to the wall inside the Quest Airlock aboard the International Space Station. The Expedition 50 crew performed routine maintenance on the suits throughout December to prepare for upcoming spacewalks in January 2017 that will see the astronauts work in tandem with external robotics to install six new lithium-ion batteries on the station.

Today: Extravehicular Activity (EVA) Prep: The crew reviewed procedures for the upcoming S4 Battery EVA.

During this session the crew reviewed the generic EVA prep, emergency and post EVA procedures along with the EVA specific procedures, detailed timelines, and EVA systems briefing. Earlier today ground teams tied Channel 3A to Channel 3B via Seamless Power Channel Handover prior to starting the process of completely discharge the Channel 3A batteries which is expected to be completed on Friday.

Fluid Shifts Dilution Measurements: The third of three 49S subjects initiated their Flight Day 45 (FD45) Fluid Shifts Dilution Measurements activities. Beginning with wakeup the subject collected saliva, blood and urine and inserted them into Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) prior to ingesting a Sodium Bromide (NaBr) tracer. Throughout the day, the crew performed additional urine, blood, and saliva collections, inserting those samples into MELFI as well. Finally, the crew configured for tomorrow's Baseline Imaging in the USOS. Fluid Shifts is divided into three experiment portions - Dilution Measurements, Baseline Imaging, and Baseline Imaging with Chibis (Lower Body Negative Pressure). The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut's eyes. Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is investigated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and eye damage.

Japanese Experiment Module Airlock (JEMAL) Depress: Following the successful installation of the J-Small Satellite Orbital Deployer (SSOD) #6 on the JEMAL slide table, the crew depressed the airlock in preparation for the mid-January deployment of the satellites. The J-SSOD facility provides a reliable, safe and economically viable means of deploying research small satellites into Earth orbit. Atmospheric and surface monitoring, radio communications testing, and small object and sample return to the ground for testing and analysis are all potential candidates for this facility.

Veg-03 Harvest and Stow: The crew performed the final harvest of the Outredgous Romaine Lettuce from the Veggie facility today. Leaves were collected divided between those for consumption and those for return that were placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). Following the harvest, the Veggie equipment was cleaned and stowed. The overall goal of Veg-03 is to further demonstrate proof-of concept for the Veggie plant growth chamber and the planting pillows using 'Outregous' Red Romaine lettuce. Future long-duration missions into the solar system, will require a fresh food supply to supplement crew diets, which means 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 new Veggie hardware, which crew members will soon use to grow cabbage, lettuce and other fresh vegetables in space. 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 Mobility Unit (EMU) 3008 Loop Scrub: Last Friday the crew began EMU 3008 loop scrub which could not be completed due to a leak at the Service and Cooling Umbilical (SCU) Display and Control Module (DCM) interface. Following yesterday's installation of a new SCU, this morning the crew completed the activation and checkout of the new equipment followed by a nominal EMU 3008 loop scrub.
