ISS Daily Summary Report – 04/16/15

SpaceX-6(SpX-6) Status:  Dragon has successfully completed several burns today on its way to station.  Cristoforetti and Virts are scheduled to capture Dragon tomorrow morning at approximately 06:00 CDT.  

Space Aging and Nematode Muscle Familiarization: Kelly reviewed overview messages on 2 JAXA experiments currently onboard SpX-6.  Both experiments will study the impacts of the zero-gravity environment on C. elegans roundworms.  In Alterations of C. elegans muscle fibers by microgravity (Nematode Muscles), investigators hope to clarify how and why these changes take place in microgravity. Studying worms exposed to both microgravity, and gravity-like conditions in a centrifuge, could help scientists understand the molecular mechanisms responsible for muscle atrophy and other spaceflight-induced changes.  In the Study of the Effects of Spaceflight on the Aging of C. elegans (Space Aging), the crew will grow millimeter-long C. elegans roundworms in microgravity and compare their health and longevity with control specimens on Earth.  Both experiments will be incubated in the JAXA Cell Biology Experiment Facility (CBEF).

The Effect of Long-Term Microgravity Exposure on Cardiac Autonomic Function (Biological Rhythms): Kelly continued his 48-hour data collection using Holter Electrocardiogram (ECG).  This morning, he completed the first 24-hour collection then exchanged the memory card and battery and started the next 24-hour collection. Biological Rhythms 48 hours studies the effects of long-term microgravity exposure on heart function by analyzing an astronaut’s electrocardiogram for 48 hours. While space station keeps Greenwich Mean Time (GMT), it remains unknown whether a separate biological rhythm is imposed on long-term flight crews. To study this astronauts wear an Actiwatch sleep monitor for 96 hours and a Holter electrocardiograph for 48 hours in the middle of that sequence.

Russian Joint Research (RJR) Microbial Air Sampler (MAS) and Surface Sample Kit (SSK) Sampling: Padalka is currently taking air samples and will later take surface samples (fungal and microbial) in modules throughout the ISS. These samples will be incubated and analyzed on Tuesday, April 21. The investigation refines locations and surfaces prone to microbial contamination throughout the ISS, shares monitoring technologies and data between NASA and Roscosmos, and provides a scientific basis for decisions about future microbial monitoring, both on ISS through its extended life, and on other future human exploration spacecraft.

Dragon Robotics On-Board Trainer (RoBOT) On-Board Training (OBT): In preparation for tomorrow’s capture and berthing of the Dragon vehicle, the USOS crew conducted the second session of this training. They completed 2 Capture Point (CP) Hold runs which allows practice free drift timing, malfunction resolution and nominal rate approaches. They also practiced 2 meter approaches. Following the training, the crew reviewed Dragon attached phase operations.

Centerline Berthing Camera System (CBCS): Virts installed the CBCS and all related avionics for Dragon mating at Node 2 Nadir. He performed a video system checkout by routing CBCS to the Robotic Work Station (RWS) and Ground, then powered down prior to removing the CBCS.
