New Status: H-II Transfer Vehicle (HTV)-4 Status: HTV’s forward Reaction Control System (RCS)-A oxidizer latch valve exhibited two recurrences of the unexpected “closed” indication during the past 24 hours. HTV continues to fly on the RCS-B string with RCS-A available as a backup. If this occurs on the RCS-B string during free flight, Japan Aerospace …
New Status: Advanced Colloids Experiment (ACE)-1: FE-6 Nyberg mixed the 6th of 10 wells for the ACE-1 experiment. ACE-1 is the first in a series of microscopic imaging investigations of materials which contain small colloidal particles which have the specific characteristic of remaining evenly dispersed and distributed within the material. This investigation takes advantage of …
New Status: H-II Transfer Vehicle 4 (HTV4) Status: Yesterday HTV4 telemetry indicated that the Reaction Control System (RCS)-A latching valve was closed unexpectedly. Ground teams tested the latching valve today and determined that both the latch and RCS-A are working nominally. They concluded that the anomaly was a transient in the switch that detects the …
New Status: H-II Transfer Vehicle 4 (HTV4) Status: HTV4 launched successfully Saturday August 3rd at 2:48 PM CDT from Tanegashima Space Center, Japan. Capture and berthing are planned for Friday August 9th at 6:30 AM CDT. Over the weekend, Reaction Control System (RCS) and Main Engines thruster testing and leak checks were performed on both …
New Status: InSPACE-3 Operations: Flight Engineer (FE)-6 Nyberg performed her first two test sessions of InSPACE-3 today. InSPACE-3 obtains data on fluids containing ellipsoid-shaped particles that change the physical properties of the fluids in response to magnetic fields. InSPACE-3 collects and records data on fluids containing ellipsoid-shaped particles that change the physical properties of the …
New Status: Multi-Purpose Small Payload Rack (MSPR) Combustion Chamber (CC) Communication Cable Checkout: Flight Engineer (FE)-3 Cassidy successfully performed activation and checkout of the MSPR CC Communication Cable. Following this activity, ground specialists initiated steps to verify the video quality downlinked from the G1 camcorder. Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions (InSPACE)-3 …
Here is a video of a bright Perseid seen by our all-sky camera located at PARI (NC) in the early morning hours of July 30. Several Perseids have already been detected and they are not set to peak for over a week! The nights of August 11-12 and 12-13 will be the best time to observe, …
New Status: Ocular Health: The crew continued Ocular Health activities with Flight Engineer (FE)-3 Cassidy acting as Crew Medical Officer (CMO) to perform ultrasound scans on FE-5 Parmitano and FE-6 Nyberg. Parmitano and Nyberg also performed cardiac ultrasound scans and blood pressure measurements using the Ocular Health hardware. The cardiac ultrasound aims to obtain vascular …
New Status: Japan Aerospace Exploration Agency (JAXA) Layer2 Ethernet Hub and Multiplexer (LEHX) Setup: Flight Engineer (FE)-3 Cassidy configured the LEHX Hub and a System Laptop Terminal (SLT) with a medium rate data cable to enable communication with the Improved Payload Ethernet Hub Gateway (iPEHG). He set up the SLT to communicate with the Joint …
New Status: 52P Launch and Dock: 50P launched at 3:45pm CDT Saturday with nominal ascent. Rendezvous and docking occurred at 9:26pm CDT and were completed successfully in automated mode. H-II Transfer Vehicle (HTV)-4 Rendezvous and Capture On-Board Training (OBT): Flight Engineer (FE)-3 Cassidy, FE-5 Parmitano, and FE-6 Nyberg conducted proficiency training in preparation for HTV-4 …
