ISS Crew Ready for Great American Eclipse and Dragon CRS-12 Experiments

Expedition 52 international 6-member crew is hard at work 400 km above the Earth. Among the hundreds of experiments running at ISS at any given time, the arrival of SpaceX Dragon CRS-12 has brought multiple studies involving cosmic rays, cacti, crystal growth, bacteria, pharmaceuticals, stem cells, roundworms, freeze drying, science literacy (aka “Story Time from Space”), multiple Student Spaceflight Experiments and CubeSats to be deployed via Nanoracks Deployer. They are also studying more efficient solar arrays, physics of neutron stars, and adverse effects of prolonged exposure to microgravity on the heart. Expedition 52 is predicted to observe the Great American Eclipse as a partial eclipse and view the Moon’s shadow cast across the continent 3 times Aug 21 while orbiting at 27,577 kph. Commander Fyodor Yurchikhin, Jack Fischer and Peggy Whitson are getting Soyuz MS-04 ready for their return to Earth Sep 3. Peggy Whitson holds the record for cumulative time in Space by any American Astronaut. On her landing, Whitson will have spent nearly 667 days in Space. Paolo Nespoli, Randy Bresnik and Sergey Ryazanskiy will remain aboard ISS and begin Expedition 53. (Image Credit: NASA, Roscosmos, ESA)
