Payloads: Cardinal Heart 2.0: Microscopy and video recordings were performed on eight BioCell tissue chambers. A previous investigation showed that four weeks of microgravity exposure caused significant changes in heart cell function and gene expression that could lead to long-term damage or cardiac muscle atrophy. Effect of Microgravity on Drug Responses Using Heart Organoids (Cardinal …
The Journey of a Carbon Atom: From Space, NASA’s PACE Mission Detects Carbon in the Sky, Land, and Sea

Whether in plants or animals, greenhouse gases or smoke, carbon atoms exist in various compounds as they move through a multitude of pathways within Earth's system. That's why NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission – scheduled to launch in January 2024 – was designed to peer down at Earth from space to see …
