NASA ISS On-Orbit Status 3 April 2015

NASA astronaut Scott Kelly (left) is happy to be aboard the International Space Station after the hatch opening of the Soyuz spacecraft Mar. 28, 2015. Kelly traveled with Expedition 43 Russian cosmonauts Mikhail Kornienko and Gennady Padalka of the Russian Federal Space Agency (Roscosmos) on the Soyuz TMA-16M that launched Friday, March 27, 2015 from Baikonur, Kazakhstan. Kelly and Kornienko will spend a year in space and return to Earth on Soyuz TMA-18M in March 2016. Most expeditions to the space station last four to six months. By doubling the length of this mission, researchers hope to better understand how the human body reacts and adapts to long-duration spaceflight. This knowledge is critical as NASA looks toward human journeys deeper into the solar system, including to and from Mars. Credit: NASA.

A wide variety of research exploring how life adapts to long-term exposure to microgravity took place on the International Space Station Friday. The crew members also worked on cargo transfers to and from a pair of docked vehicles.

More crew Ocular Health eye checks were on the schedule as scientists study the fluid shifts caused by microgravity and how they affect a crew member's vision. New software was loaded on computers for the Rodent Research study, a life sciences experiment that was delivered on a SpaceX mission in January.

NASA astronaut Scott Kelly, who collected a saliva sample for stowage in a science freezer, and his twin brother on the ground Mark Kelly are the subjects of the Twins study. That investigation compares the two brothers, one in space and one on the ground, and explores how the different environments affect the twins with identical genes.

On the Russian side of the orbital lab, the crew unloaded gear from the recently docked Soyuz TMA-16M spacecraft. The ISS Progress 57 space freighter, docked to the Pirs docking compartment, is also being packed with trash ahead of its departure and fiery disposal April 25.

On-Orbit Status Report

Ocular Health (OH): Kelly and Kornienko performed the last of the activities for their Flight Day (FD) 10 Ocular Health session, completing ocular and cardiac ultrasound scans. The ultrasound images will be used to identify changes in globe morphology, including flattening of the posterior globe, and document optic nerve sheath diameter, optic nerve sheath tortuosity, globe axial measurements, and choroidal engorgement. The protocol calls for a systematic gathering of physiological data to characterize the risk of microgravity-induced visual impairment/intracranial pressure in ISS crewmembers. Researchers believe that the measurement of visual, vascular and central nervous system changes over the course of this experiment and during the subsequent post-flight recovery will assist in the development of countermeasures, clinical monitoring strategies, and clinical practice guidelines.

Aniso Tubule: Cristoforetti retrieved the Aniso samples from the CBEF and installed them on the Aquatic Habitat (AQH) microscope. Over the next two days, ground controllers will send commands and observe the samples. Aniso Tubule examines growth modifications of Arabidopsis hypocotyls in space. Scientists will analyze the changes in dynamics of cortical microtubules and microtubule-associated proteins by observing Arabidopsis hypocotyls and microtubule-associated proteins with a fluorescence microscope.

Japanese Experiment Module (JEM) Intermodule Ventilation (IMV) Flow Measurements: Virts and Cristoforetti completed this regularly scheduled task to measure air velocity in the JEM using the Velocicalc instrument. Measurements were taken in the overhead aft, starboard aft and starboard forward inlets.

Urine Processing Assembly (UPA) Status: Ground controllers have attempted a couple of UPA process cycles today which effectively generated no water. The teams believe this is due to a higher than normal amount of air in the system. The team continue to work on a plan to regain the UPA functionality.

Water Processing Assembly (WPA) Status: The WPA is currently reprocessing due to high conductivity levels. Based upon the ground team's recommendation, the Gas Separator temperatures were raised to 175 F prior to attempting another reprocess cycle. Conductivity decreased below 50 µmhos/cm after 12 hours in process. However the conductivity levels have been trending higher throughout the day, with no commanded changes to the system. The teams are reviewing the data to determine the forward plan.
