Payloads Combustion Integrated Rack (CIR) / Advanced Combustion via Microgravity Experiments (ACME): The crew performed the steps necessary to lubricate the quick disconnect (QD) for the gas chromatograph argon gas bottle. They also replaced the N2/O2 gas bottle at manifold 2 and installed an ethane fuel bottle at the manifold 4 location. This was performed …
Payloads Antimicrobial Coatings (AC) Touch: Per standard procedure, the crew touched both the coated and uncoated coupons for this long-term investigation, and then took photos of the experiment. Boeing Environment Responding Antimicrobial Coatings tests an antimicrobial coating on several different materials that represent high-touch surfaces. Some microbes change characteristics in microgravity, which could create new …
ISS Reboost: Today the ISS performed a reboost using the SM Aft 75P R&D thrusters at 1:09 PM CT. This is the first of two planned reboosts to set up phasing for 64S rendezvous on April 9th and 63S landing on April 17th. This reboost also facilitates the separation of the ISS trajectory from re-encountering …
Exposed Pallet 9 (EP9) Jettison: At 7:30 AM CT today, robotics ground controllers commanded an SSRMS disposal jettison of the EP9, carrying old Nickel-Hydrogen batteries. The EP9 has the approximate mass of a large SUV and is predicted to re-enter Earth’s atmosphere in two-to-four years. The EP9 was delivered to the ISS inside of the …
Payloads Antimicrobial Coatings Touch: Per standard procedure, the crew touched both the coated and uncoated coupons for this long-term investigation. Boeing Environment Responding Antimicrobial Coatings tests an antimicrobial coating on several different materials that represent high-touch surfaces. Some microbes change characteristics in microgravity, which could create new risks to crew health and spacecraft systems as …
Payloads Asian Herb Watering: The crew performed a periodic watering for the plants growing in the Asian Herb experiment. The plants will grow for a period of around 30 days, then be preserved for return to the ground. Microgravity affects the growth of plants and understanding the nature of these changes is important for future …
United States On-orbit Segment (USOS) Extravehicular Activity (EVA) #72 – ISS Upgrades III: Today, EV1 Kate Rubins and EV2 Soichi Noguchi performed a 6 hour 56 minute EVA and completed the following tasks during the ISS Upgrades III EVA: 4B ISS Roll Out Solar Array (IROSA) Mod Kit Installation 2B IROSA Mod Kit Modification Worksite …
Payloads Exploration Environmental Control and Life Support System: Brine Processor System (BPA): The crew installed the BPA hardware. The Exploration ECLSS: BPA is designed to improve water recycling on the ISS and boosts the efficiency of water recycling for the Artemis generation. Sally Ride Earth Knowledge Acquired by Middle Schools (EarthKAM): The crew performed a …
Payloads Exploration Environmental Control and Life Support System: Brine Processor System (BPA): The crew routed the power cable to the BPA hardware. The BPA is designed to improve water recycling on the International Space Station and boost the efficiency of water recycling for the Artemis generation. Dose Distribution Inside the ISS – 3D (DOSIS-3D): The …
Payloads Actiwatch Plus: A crewmember connected Actiwatch units to the Human Research Facility (HRF)-2 rack to allow ground teams to downlink data. The Actiwatch is a waterproof, nonintrusive, sleep-wake activity monitor worn on the wrist of a crewmember. The device contains a miniature uniaxial accelerometer that produces a signal as the subject moves. The data …
