Space Station Science Highlights: Week of July 9, 2018

ISS – Expedition 56 Mission patch.

July 16, 2018

Last week, Progress, a Russian resupply spacecraft, delivered more than 5,700 pounds of crew supplies and cargo to the crew members aboard the International Space Station. Monday’s arrival of the spacecraft set a milestone for station operations by arriving with its cargo in just 3 hours and 40 minutes, or only two Earth orbits.

Blood samples collected in support of JAXA investigations

Blood carries molecular signals released from cells inside the body. For the Cell-Free Epigenome (CFE) study, blood samples are collected from astronauts and cellular genes are analyzed. The results provide insight into how human bodies function during spaceflight. The Medical Proteomics investigation evaluates changes of proteins in blood serum, bone and skeletal muscles after space flight, and also supports identification of osteopenia-related proteins.

By combining research results for mice, astronauts and ground patients, proteins related to osteopenia can be identified using the latest proteome analysis technique. It is anticipated that the use of the marker proteins related to osteopenia will be of benefit in the future for assessing the health of astronauts as well as osteoporosis patients on ground.

Last week, crewmembers collected blood samples in support of both investigations.

Experiment investigates protein associated with various diseases

Amyloid fibril is the protein aggregation that is known to be associated with various diseases including Alzheimer’s disease and diabetes. To develop treatments for Alzheimer’s disease, it is important to clarify the mechanism of amyloid fibril formation. In the Characterization of Amyloid Formation Under Microgravity Environment: Toward Understanding the Mechanisms of Neurodegenerative Diseases (Amyloid) investigation, researchers prepare the high-quality homogeneous amyloid fibrils using the microgravity environment, and bring back the samples to characterize the fibrillation process and intermediate structure.

Last week, crew members transferred the Amyloid samples from a -95 degree Celsius container within the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) to a 2 degree Celsius container, then attached to the Cell Biology Experiment Facility (CBEF) to incubate before being placed back into MELFI.

Study examines spaceflight impact on sperm cells

The survival of multiple generations of organisms beyond the Earth requires proper function of normal sperm and eggs cells. There exists a significant knowledge gap on impacts of spaceflight conditions on the fertility-dependent functions of sperm. The goal of the Spaceflight-Altered Motility Activation and Fertility-Dependent Responses in Sperm (Micro-11) investigation is to study how sperm cells are affected by the spaceflight environment.

Last week, the crew performed five runs of the Micro-11 investigation. For each run, the Micro-11 microscope was checked out, configured and calibrated before samples were fixed and loaded into the device for imaging. Finally, the samples were stored in MELFI. There will be 13 runs conducted for the Micro-11 investigation.

Other work was done on these investigations:, CEO, HDEV, Probiotics, Space Algae, HREP-HICO, HREP-RAIDS, Biomolecule Sequencer, MICS, ACE-M-2, Made in Space-Fiber Optics, Rodent Research-7, LMM Biophysics-4, Neuromapping, MagVector, MICS, Food Acceptability, MELFI, Angiex Cancer Therapy, Biochem Profile, Repository, Atomization, SAMS-II and Manufacturing Device.
