Derrick Matthews, at left, moderator with NASA Communications, introduces Dr. Lucy Low, with the National Institutes of Health, during a What’s On Board science briefing to NASA Social participants at the agency’s Kennedy Space Center in Florida on April 29, 2019. The briefing was held for SpaceX’s 17th Commercial Resupply Services (CRS-17) mission to the International Space Station. Low presented on the Tissue Chips in Space project that will test the ability of tissue chip technology to mimic how human organs work and reveal what effects microgravity has on tissue function. Headed to the space station will be lung and bone marrow chips, kidney chips, chips modeling the blood-brain barrier, and bone and cartilage chips. NASA’s Orbiting Carbon Observatory-3 (OCO-3) and Space Test Program-Houston 6 (STP-H6) are two of the experiments that also will be delivered to the space station on CRS-17. The SpaceX Falcon 9 rocket and Dragon cargo module are scheduled to launch no earlier than May 3, 2019, from Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida.
