The SpaceX CRS-17 mission includes a variety of payloads representing diverse science investigations, ranging from the life and physical sciences to Earth observation and remote sensing, as well as educational experiments intended to engage and excite the next generation of scientists and engineers.

Below are highlights of sponsored ISS National Lab investigations that are part of the SpaceX CRS-17 mission to the space station.

An ISS Experiment on Electrodeposition
University of Florida
Principal Investigator (PI): Dr. Kirk Ziegler

This project seeks to test electrochemical deposition onboard the International Space Station (ISS) to determine if the absence of gravity reduces interfacial instability patterns produced during electrodeposition. Electrodeposition is a process by which an electric current is used to form thin metal features on conductive surfaces like electrodes. This investigation seeks to utilize the microgravity environment on the ISS, which eliminates gravity-driven confounding factors such as convection, to control the electrodeposition processes so that controlled growth of ordered, high-aspect-ratio structures with fewer imperfections can be achieved. Results from this investigation could be applied to improve the manufacture of many systems on the ground, such as microfluidic reactors, microscale heat exchangers, sensors, and catalytic converters for use in both industrial (cell phones, computers, etc.) and medical (implantable devices) applications.

Cartilage-Bone-Synovium Microphysiological System (NCATS-Cartilage-Bone-Synovium)
Massachusetts Institute of Technology
PI: Dr. Alan Grodzinsky

Post-traumatic osteoarthritis causes about 12% of osteoarthritis of the hip, knee, and ankle, and is a common condition in otherwise healthy young to middle-aged individuals, affecting about 5.6 million people in the United States. This project represents a relevant human tissue chip platform with the potential to provide several pharmacological treatment options for osteoarthritis patients. This project will study the effects of spaceflight on musculoskeletal disease biology, specifically, post-traumatic osteoarthritis and bone loss using a tissue chip cartilage-bone-synovium joint model. Researchers will co-culture primary human explants of intact (native) cartilage, bone, and synovial joint capsule tissue (obtained from a long-standing collaborating human donor bank). The effects of pharmacological agents to ameliorate bone and cartilage degeneration will be tested on Earth and onboard the ISS, using a quantitative and high-content experimental and computational approach.

Cell Culture Module Fluid Behavior Demonstration
Space Tango
PI: Twyman Clements

This project seeks to test variables of fluid exchange in a common 96-well culture plate. Images from a series of fluid experiments will be used to assess capillary action of the plate in microgravity, and results will be compared to ground-based controls to identify an optimum microgravity fluid exchange procedure. The resulting data will help optimize media exchanges for future cell culture research in microgravity. Increased understanding of fluid exchange in commercially-available 96-well plates enables the development of more reliable and affordable ground control studies for microgravity cell culture experiments.

Effects of Microgravity on Human Physiology: Blood-Brain Barrier Chip (NCATS-Brain Chip)
Emulate
PI: Dr. Chris Hinojosa

This project seeks to understand how the unique environment of the ISS National Lab affects blood-brain barrier (BBB) physiology. The research team will validate and develop Emulate’s proprietary tissue chip technology platform for experimentation with human cells. The BBB is a semi-permeable barrier that allows the selective passage of certain molecules and gases while preventing the passage of others. It is a critical component involved in maintaining homeostasis, and disruption of the barrier can lead to or cause neurological dysfunction or disease. This technology will become available to the broader scientific community for studies on human physiology and disease in space.

Genes in Space-6
Woodbury High School, MN and Mounds View High School, MN (through funding from Boeing)
Co-PI’s: David Li, Rebecca Li, Michelle Sung, Aarthi Vijayakumar

The sixth student investigation awarded through the Genes in Space student research competition seeks to improve understanding of microgravity’s effects on the mechanisms of DNA repair. The team’s experiment will use CRISPR/Cas9 genome editing together with DNA amplification using a miniPCR (polymerase chain reaction) machine to make copies of the DNA onboard the ISS. The experiment will then use sequencing technology to read the DNA while in orbit. By increasing our understanding of the effects of microgravity on the mechanisms of DNA repair, the team’s project aims to protect astronauts from cosmic radiation. This is the winning student experiment from the Genes in Space contest, in which students in grades 7 through 12 compete to send their DNA experiments to the space station. This will be the first student experiment coupling DNA amplification by PCR with DNA sequencing onboard the ISS.

Lung Host Defense in Microgravity (NCATS-Lung Host Defense)
Children’s Hospital of Philadelphia
PI: Dr. G. Scott Worthen

This project will test two engineered microphysiological systems (also called tissue chips or organs-on-chips), one that models the airway and one that models bone marrow, in microgravity. The spaceflight environment has been found to cause human immune dysfunction, and infections are commonly reported onboard spacecraft. However, the mechanisms behind spaceflight-induced immune dysfunction are not well understood. Through use of tissue chips in microgravity, the research team seeks to gain a better understanding of immune dysfunction and the link between immune system health and susceptibility to infection. In a second flight project, the research team plans to combine the airway and bone marrow models to emulate and understand the integrated immune responses of the human respiratory system. Ultimately, this research could lead to novel therapeutics for Earth-based patients with compromised immune systems as well as preventive measures for astronauts during spaceflight.

ASU/National Cancer Institute
PI: Jose M. Martin Garcia

Through this program, the National Cancer Institute’s Chemical Biology Consortium (CBC) will conduct multiple protein crystallization experiments on the ISS aimed at drug discovery. The goal is to develop an accelerated drug discovery pipeline that takes advantage of macromolecular crystallization in microgravity and fits within the CBC’s established drug discovery process. In order to achieve this goal, the CBC will utilize commercial off-the-shelf (COTS) microgravity crystallization platforms and establish a queue of multiple high-value cancer-related proteins, allowing for efficient resource utilization and late-stage selection of payloads. This investigation seeks to grow high-quality crystals of the Taspase1 enzyme. Results could help researchers develop drugs to treat cancers such as leukemia, certain types of breast cancer, and glioblastoma (an aggressive brain cancer).

Structure of Proximal and Distal Tubule Microphysiological Systems (NCATS-Kidney Cells)
University of Washington
PI: Dr. Jonathan Himmelfarb

This project aims to develop physiologically relevant proximal and distal tubule tissue chip systems for study on the ISS National Lab. Through these systems, investigators will examine Vitamin D bioactivation and homeostasis as well as disease models that promote proteinuria (excess protein in the urine) and the formation of kidney stones. Kidney dysfunction can precipitate serious medical conditions including proteinuria, osteoporosis, and the formation of kidney stones. These conditions occur more frequently, and progress faster, in astronauts onboard the ISS. This tissue chip project uses a kidney model to understand how microgravity and other factors affect kidney function, toward development of improved treatment options for patients on Earth.
