As flight controllers monitored their data, the decision was made to allow the Expedition 56 crew to sleep since …

Biomolecule Extraction and Sequencing Technology (BEST): The crew prepared BEST RNA samples and began 48 hour sequencing on the Biomolecule Sequencer. The BEST investigation studies the use of sequencing for identification of unknown microbial organisms living on the ISS, and how humans, plants and microbes adapt to living on the ISS. SpaceTex-2 and Metabolic Space: …

NASA and Northrop Grumman are now targeting Saturday, Oct. 6, 2018, for the launch of the agency’s Ionospheric Connection Explorer, or ICON. The spacecraft will launch aboard a Northrop Grumman Pegasus XL rocket from Cape Canaveral Air Force Station in Florida. The launch window is 90 minutes starting at 4:00 a.m. EDT and ICON will be launching off the coast …

The six residents aboard the International Space Station today continued exploring how living in space impacts their bodies. The Expedition 56 crew also worked on science hardware and life support gear to ensure the orbital complex is in tip-top shape. Three astronauts helped doctors understand what is happening to their eyes in the weightless environment …

ExPRESS Rack (ER) 5 Payload Isolation: On August 23rd, the ER5 Subsystem Valve was removed and replaced (R&R’d) after a Japanese Experiment Module (JEM) Moderate Temperature Loop (MTL) leak had been isolated to ER5. Earlier today, the crew disconnected the supply and return lines to the Space Automated Bioproduct Laboratory (SABL) and Plant Habitat facilities …
