ISS On-Orbit Status Report

Grasp Commissioning:  To complete commissioning for the Grasp investigation hardware, Pesquet performed tasks in a seated position. Grasp is intended to provide insight into how the central nervous system integrates information from different sensory modalities encoded in different reference frames to coordinate movements of the hand with objects in the environment.  Performed on the ISS, …

OsteoOmics:  The crew fixated BioCells in Biocell Habitat 1 inserted the sample into the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).  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, …

External (EXT) Multiplexer/Demultiplexer (MDM)-1 R&R Extravehicular Activity (EVA):  With IV support from Thomas Pesquet, today Peggy Whitson (EV1) and Jack Fischer (EV2) performed a 2 hour 46 minute EVA to Remove & Replace (R&R) the EXT MDM-1 that failed on Saturday, May 20th. While Whitson performed the EXT MDM R&R, Fischer installed the Lab Nadir …

External (EXT) Multiplexer/Demultiplexer (MDM)-1 Failure: On Saturday EXT MDM-1 experienced an anomaly. Attempts to recover the MDM remotely were unsuccessful.  Ground Teams configured EXT MDM-2 as primary and set up systems for the next worse failure per established Flight Rules. An IMMT was held Sunday and directed Team 4 to assess the feasibility of performing …

Fluid Shifts: A 50S crewmember performed their Flight Day (FD) 180 Fluid Shifts Chibis operations in the Russian Segment. They donned the Lower Body Negative Pressure (LBNP/Chibis) device while the operator, with ground support in Moscow, assisted in the medical monitoring.  While the subject was in the LBNP and experiencing the negative pressure (pulling the …

NanoRack Cubesat Deployer (NRCSD) #11 Deploy: The final six CubeSats for NRCSD #11 were deployed today from the ISS:  Aerosat, Link, CSUNSat, UpSat, SpaceCube and Hoopoe.  CSUNSAT was developed at California State University Northridge (CSUN) in partnership with the Jet Propulsion Laboratory (JPL).  It is being used to validate in space a new low temperature …

NanoRack Cubesat Deployer (NRCSD) #11 Deploy:  Five Cubesats were deployed today from the ISS:  Phoenix, Xcubesat, Qbee, Altair and SHARC.  ALTAIR is a technology demonstration / risk reduction mission for critical subsystems for the ALTAIR product line of spacecraft.  SHARC (Spacecraft for High Accuracy Radar Calibration) hosts a series of experimental payloads including a C-band …

NanoRack Cubesat Deployer (NRCSD) #11 Deploy:  Six cubesats were deployed today from the ISS: SGSat, CXBN-2 and IceCube, SOMP2, HAVELSAT, and COLUMBIA. SGSat demonstrates the attitude determination and control system reliant on utilization of pictures of star fields to orient the satellite and validate new software used to predict the satellite’s path as it experiences …

SkinSuit:  Over the weekend a crewmember performed two days of Skinsuit activities. With assistance from an operator, measurements of the subject were taken after donning the suit in the morning and before doffing it in the afternoon. The Skinsuit is a tailor-made overall with a bi-directional weave specially designed to counteract the lack of gravity …

EXPRESS Pallet Controller Assembly (ExPCA) Extravehicular Activity (EVA) #42: EV1 Peggy Whitson and EV2 Jack Fischer performed the ExPCA EVA today. At the start of In-Suit Light Exercise (ISLE) Prebreathe, a water leak was discovered at the Service Cooling Umbilical (SCU) for Fischer’s suit.  The leaking SCU was subsequently disconnected and the functioning SCU was …
