NASA Highlights Science on 17th SpaceX Resupply Mission to International Space Station

Expedition 58 Flight Engineer Anne McClain of NASA is pictured in the cupola holding biomedical gear for the Marrow experiment. The study measures fat changes in the bone marrow before, and after exposure to microgravity. In addition, this investigation measures specific changes of red and white blood cell functions. Bone marrow fat is measured using magnetic resonance. Red blood cell function is measured with a breath sample analyzed with a gas chromatograph, and white blood cell function is studied through their genetic expression.

NASA will host a media teleconference at 11 a.m. EDT Monday, April 22, to discuss select science investigations launching on the next SpaceX commercial resupply flight to theInternational Space Station.

Audio of the teleconference will stream live online at:

SpaceX is targeting5:55 a.m. Friday,April 26, for the launch of its Dragon spacecraft on a Falcon 9 rocket fromSpace Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

Participants in the briefing will be:

  • Annmarie Eldering, project scientist at NASAs Jet Propulsion Laboratory, who will discusshow the Orbiting Carbon Observatory-3 (OCO-3), to be installed on theJapanese Experiment Module-Exposed Facilityof the orbiting laboratory, observes the complex dynamics of the Earths atmospheric carbon cycle.
  • Gisela Detrell, head of the Life Support System research group at the Institute of Space Systems – University of Stuttgart, Germany, who will talk aboutPhotobioreactor, an investigation aimed at demonstrating the use of biological processes to create a hybrid life support system. On future long-duration missions, this approach could reduce the amount of food, water, and other essentials that crews have to bring from Earth.
  • Lucie Low of the National Center for Advancing Translational Sciences at the National Institutes of Health, who will discusstissue chips, or organs-on-chips. Tissue chips model the detailed physical structure of human tissue using cells grown on an artificial scaffold, enabling higher-accuracy disease modeling and drug testing.
  • Alan Grodzinsky of the Massachusetts Institute of Technology, who will discuss his teamstissue chip investigationthat will study the effects of spaceflight on musculoskeletal disease biology.The goal of this research is to treat the root cause of post-traumatic osteoarthritis disease and prevent permanent joint damage, rather than mask the symptoms with painkillers later in life.
