Microbes, Mucus, and Brain Organoids—Experiments to Prevent and Treat Disease Launching on Next Space Station Resupply Mission

KENNEDY SPACE CENTER (FL), October 30, 2023 — From research on microbes to studies on brain organoids, a new pharmaceutical lab, and the role of mucus in medication delivery, several payloads launching on SpaceX’s 29th Commercial Resupply Services mission(Abbreviation: CRS mission) A CRS mission is a cargo resupply mission contracted by NASA to deliver supplies and research to the International Space Station on commercial spacecraft as part of the CRS contract with three commercial companies. As part of CRS missions, experiments currently return to Earth on SpaceX Dragon spacecraft that splash down in the ocean. to the International Space Station (ISSInternational Space Station) aim to prevent or treat disease. The mission, contracted by NASANational Aeronautics and Space Administration, is scheduled to launch no earlier than 10:01 p.m. EST on November 5, 2023, with more than 25 payloads sponsored by the ISS National Laboratory®.

Below highlights some of the payloads on SpaceX CRS-29 sponsored by the ISS National Lab that aim to bring value to humanity and foster commerce in low Earth orbit(Abbreviation: LEO) The orbit around the Earth that extends up to an altitude of 2,000 km (1,200 miles) from Earth’s surface. The International Space Station’s orbit is in LEO, at an altitude of approximately 250 miles.:

• An investigation from the Naval Research Laboratory will examine how microgravityThe condition of perceived weightlessness created when an object is in free fall, for example when an object is in orbital motion. Microgravity alters many observable phenomena within the physical and life sciences, allowing scientists to study things in ways not possible on Earth. The International Space Station provides access to a persistent microgravity environment. affects the behavior of microbes in producing melanin. The team will examine how microgravity and cosmic radiation may lead to new melanin variants that could be used to produce new biomaterials with applications both on Earth and in space.
• Boeing will test an antimicrobial polymer surface coating against microbes in multiple locations on the ISS. Results may provide insights to mitigate the risk of infection on future space missions and space platforms.
• The U.S. National Science Foundation (NSF) continues its collaboration with the ISS National Lab by funding two biotechnology investigations on this mission. A research team from the University of California, Santa Barbara aims to leverage microgravity to understand the how mucus that lines the human airway affects the delivery of medication to the lungs. The team will use gel-coated tubes to study the role of mucus in the transport of liquid plugs through the airway. Results from this investigation could improve modeling of drug delivery for treatments such as surfactant replacement therapy (a treatment for infants with respiratory distress syndrome). Researchers at the University of California, San Francisco aim to utilize 3D-immune-liver tissue chips in space to better understand the relationship between immune system aging and the ability of liver cells to regenerate. The research team will then look for possible ways to slow the aging process and enhance the liver healing process for patients on Earth.
• An investigation from the University of California, San Diego, which builds on previous space station research, will explore microgravity’s effects on stem-cell derived brain organoids. Organoids are three-dimensional cellular models that represent aspects of the human brain. This investigation aims to study accelerated aging in space to understand how cognitive decline happens in the human brain. Results could provide a better understanding of the mechanisms behind late-onset neurological conditions like dementia and Alzheimer’s and potentially lead to new treatments.
• Redwire Space, a leader in the development of space-based facilities, will launch initial elements associated with its Pharmaceutical In-space Laboratory, a platform to crystallize small organic molecules in microgravity. Redwire aims to validate the system’s capabilities by performing multiple protein crystal growth experiments. In the absence of gravity, crystals can grow larger and more uniformly, which could lead to improved therapeutics for patients. Once fully operational, this facility will be available to the life science community for future investigations.

On Tuesday, October 31, at 1 p.m. EDT, the ISS National Lab and NASA will host a webinar highlighting investigations launching on SpaceX CRS-29. Media members are invited to ask questions during the webinar but must register beforehand through the link provided in our media advisory. A recording of the webinar will also be posted on our website.

In the coming days, the ISS National Lab will put out a variety of press releases highlighting projects launching onboard the SpaceX Dragon spacecraft as part of this mission.

About the International Space Station (ISS) U.S. National Laboratory: The International Space Station (ISS) is a one-of-a-kind laboratory that enables research and technology development not possible on Earth. As a public service enterprise, the ISS National Lab allows researchers to leverage this multiuser facility to improve life on Earth, mature space-based business models, advance science literacy in the future workforce, and expand a sustainable and scalable market in low Earth orbit. Through this orbiting national laboratory, research resources on the ISS are available to support non-NASA science, technology and education initiatives from U.S. government agencies, academic institutions, and the private sector. The Center for the Advancement of Science in Space™ (CASIS™(Abbreviation: CASIS™) The nonprofit organization that manages the ISS National Lab, which receives at least 50 percent of the U.S. research allocation on the International Space Station to facilitate research that benefits humanity (NASA manages the other 50% and focuses on research for space exploration purposes).) manages the ISS National Laboratory®, under Cooperative AgreementA cooperative agreement is Federal assistance that establishes a relationship between the U.S. Government and a recipient in which the principal purpose of the relationship is to accomplish a public purpose of support or stimulation.  Since 2011, the Center for the Advancement of Science in Space™ (CASIS™) has managed the National Laboratory® through a Cooperative Agreement with NASA. with NASA, facilitating access to its permanent microgravity research environment, a powerful vantage point in low Earth orbit, and the extreme and varied conditions of space.
