H-II Transfer Vehicle (HTV)-7 Launch Status: On Sunday, Japan’s Aerospace Exploration Agency (JAXA) reported that tonight’s launch of HTV-7 has been delayed due to weather concerns. Experts are meeting later tonight (Tuesday, 11-September in Japan) to discuss the upcoming weather forecast and begin work to select a new launch date; the next earliest launch opportunity …
Airway Monitoring: Today the crew performed the Airway Monitoring US Airlock Session. The science session consists of two different protocols that are performed at both ambient, and reduced (10.2 psi) pressure in the US airlock. These protocols are the low Nitric Oxide (NO) protocol that determines how much NO is exhaled with the respiration, and …
Airway Monitoring: Today the crew continued the preparatory activities for the GMT 250 Airway Monitoring US Airlock Session. These activities included setting up the camera and hardware required for Airway Monitoring in the US Airlock. The Airway Monitoring investigation aims to determine in detail the pulmonary nitric oxide turnover in weightlessness and in combined weightless, …
Airway Monitoring: Today the crew performed preparatory activities for the GMT 250 Airway Monitoring US Airlock Session. These activities include review of big picture words, hardware location, etc. The Airway Monitoring investigation aims to determine in detail the pulmonary nitric oxide turnover in weightlessness and in combined weightless, hypobaric and hypoxic environments as well as …
Binary Colloidal Alloy Test – Cohesive Sediment (BCAT-CS): On Sunday, the crew checked the camera alignment and focus by viewing the latest BCAT images on a laptop. TheBCAT-CS investigation studies the forces between particles that cluster together by using sediments of quartz and clay particles. Conducting the research in the microgravity environment of the ISS …
Out-of-Spec ISS Cabin Pressure Decrease: Following the initial leak repair yesterday, the ISS was repressurized to nominal pressure using Progress assets. Today, the Russian crew performed additional activities for the leak repair. There was still a small leak path which the crew sealed as they continued with the repair. An additional level of repair will …
Out-of-Spec ISS Cabin Pressure Decrease: Last night, the ISS cabin pressure started dropping at the rate of one mmHg/hr. This morning the crew performed leak isolation steps via a series of hatch closures and determined the leak was in the Soyuz 55S habitation module [БО]; a pressure check of the 55S descent module was nominal. Further …
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: …
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 …
Moon Imagery: Today the crew took photographs of the full Moon and downlinked them for evaluation on the ground. If a spacecraft loses communication with the ground or with NASA’s Deep Space Network, its crew must navigate just as ancient mariners did, using the moon and stars. The Moon Imagery investigation collects pictures of the …
