By Mitzi Adams, NASA Marshall solar scientist Last August, citizens and visitors to the United States of America had a rare opportunity to see a total solar eclipse, because the path of totality ranged from Oregon to South Carolina, essentially bisecting the country. But alas, the total lunar eclipse happening on Friday, July 27, will …

A trio of studies taking place today aboard the International Space Station explored a potential cancer therapy, researched human reproduction and observed protein crystals. Eye exams were also on the schedule to understand how microgravity impacts vision. NASA astronaut Serena Auñón-Chancellor started her morning peering at endothelial cells through a microscope for the AngieX Cancer …

Progress 69P ISS Reboost: This morning at 11:10 AM CT, the ISS completed a 3m 19s reboost using 69P thrusters.  The purpose of the reboost was to start phasing for 54S landing and 55S launch in October and increased the ISS velocity by 0.40 meters per second (m/s).     External High Definition Camera (EHDC) Preparation for …

The International Space Station got an orbital boost today to position itself for a crew swap taking place later this year. Inside the lab complex, the current residents spent their time today exploring a diversity of phenomena impacted by long-term exposure to microgravity. A docked Russian Progress 69 resupply ship fired its engines this morning …

Rodent Research-7 (RR-7):  Today the crew completed the second of two days of rodent operations for the RR-7 investigation today. Crewmembers performed bone densitometer scans, blood draws, fecal pellet collections, and sampling operations.  Following these operations, the crew performed clean-up activities in the Microgravity Science Glovebox (MSG) to prepare the facility for upcoming science.  RR-7 …

  Expedition 56 crewmembers collaborated for the second day in a row studying how living in microgravity impacts rodents. The space research onboard the International Space Station is helping doctors keep astronauts healthy in space and while developing advanced therapies for humans on Earth. Rodent research, and a variety of other life science studies observing …

NASA and its mission partners are targeting Aug. 11 for the launch of the Parker Solar Probe mission to the Sun. The 45-minute launch window will open at 3:48 a.m. EDT. During final inspections following the encapsulation of the spacecraft, a small strip of foam was found inside the fairing and additional time is needed for inspection.

Rodent Research-7 (RR-7): The crew completed the first of two days of rodent operations for the RR-7 investigation today. Crewmembers performed bone densitometer scans, blood draws, fecal pellet collections, and sampling operations.  RR-7 examines how the space environment affects the community of microorganisms in the gastrointestinal tract of mice (also known as the microbiota). It …

Life science took precedence today aboard the International Space Station as the crew explored how microgravity impacts rodent physiology. The space research can help scientists improve astronaut health and treat humans on Earth. Four Expedition 56 crew members worked together throughout the day examining mice for the Rodent Research-7 study. The experiment observes how microbes …

Direct Current Switching Unit (DCSU) 3A Power on Reset (POR): Early Saturday, morning DCSU 3A experienced a POR which, due to power balancing during the current high beta period, resulted in a loss of power to some downstream loads. The crew and ground teams worked together to recover from the failure and teams continue to …
