NASA Space Station On-Orbit Status 26 September 2018 - HTV7 to Arrive Tomorrow


NASA Space Station On-Orbit Status 26 September 2018 - HTV7 to Arrive Tomorrow.

The Japanese Aerospace Exploration Agency (JAXA) cargo spacecraft that launched at 1:52 p.m. EDT Sept. 22 (2:52 a.m. Sept. 23 Japan standard time) from the Tanegashima Space Center in southern Japan is set to arrive at the International Space Station early tomorrow morning.

Beginning Thursday at 6:30 a.m., NASA will provide live coverage of the arrival of the unpiloted H-II Transfer Vehicle-7 (HTV-7) via NASA TV and online at

Capture is scheduled around 8 a.m. Coverage of the final installation to Harmony will resume at 10:30 a.m.

The HTV-7 is loaded with more than five tons of supplies, water, spare parts and experiments for the crew aboard the orbiting laboratory, including a new glovebox for life sciences investigations. The spacecraft also is carrying a half dozen new lithium-ion batteries to continue upgrades to the station's power system.

On-Orbit Status Report

Fluidics: The crew prepared the Fluidics hardware in order to perform experiment runs today. Some difficulties were encountered securing one of the fluid tanks, but this was resolved by applying layers of tape. Fluidics is a fluid mechanics experiment with two main objectives: perform a Slosh study to investigate fluid behavior under microgravity during satellite maneuvers, and a Wave Turbulence study to investigate the impact of capillary effect on wave turbulence without being masked by the effect of gravity.

Binary Colloidal Alloy Test - Cohesive Sediment (BCAT-CS): The crew transferred images to the SSC, changed the SB-800 Flash batteries, verified that the camera alignment and focus are still intact by viewing the latest BCAT images on the SSC, and re-set the intervalometer. The BCAT team has previously reported the aggregates observed in their sample cuvettes are significantly larger than achieved in Earth-based experiments. BCAT-CS focuses on the study of forces between particles that cluster together by using sediments of quartz and clay particles. Conducting the research in the microgravity environment of the ISS makes it possible to separate the forces acting on the particles over a short range (adhesive forces) versus those acting over a long range (cohesive forces).

Sally Ride Earth Knowledge Acquired by Middle Schools (EarthKAM): The crew performed a lens change during orbit day. During this activity, the 50mm lens was replaced with an 85mm lens. As of this report, over 27,000 students from 33 countries (including Russia) are participating in EarthKAM mission 63. EarthKAM allows thousands of students to photograph and examine Earth from a space crew's perspective. Using the Internet, the students control a special digital camera mounted on-board the ISS. This enables them to photograph the Earth's coastlines, mountain ranges and other geographic items of interest from the unique vantage point of space. The EarthKAM team then posts these photographs on the Internet for viewing by the public and participating classrooms around the world.

Fast Neutron Spectrometer (FNS): The crew disconnected FNS from Node 1 and moved it to US Lab. Neutron spectrometers are used to make a wide range of measurements, including studies of a planetary body's composition and measuring the flux of high-energy neutrons that could be harmful to humans. The Fast Neutron Spectrometer (FNS) investigation studies a new neutron measurement technique that is better suited for the mixed radiation fields found in deep space. Future operated and exploration missions benefit from clearer, more error-free measurement of the neutron flux present in an environment with multiple types of radiation.

Tropical Cyclone: The crew set up and configured the camera settings for untended image acquisition. The target is a midnight shot of category 5 Tropical Cyclone Trami. The Tropical Cyclone investigation is normally used to capture images of tropical cyclones and hurricanes that are rated at Category 3 or greater on the Saffir-Simpson scale. The photographic images are used to demonstrate that pseudo-spectroscopy can be used to measure the cloud altitudes to sufficient precision so that, when combined with other remote-sensing data, an accurate determination of the intensity of hurricane or cyclone can be made.

H-II Transfer Vehicle (HTV)-7 Capture and Berthing Preparations: Today the crew completed the second of two self-study OBT session using the Robotics Onboard Trainer (ROBoT) in preparation for HTV-7 approach and rendezvous tomorrow morning. During this training, they practiced their Free Drift timing, malfunction response, and nominal rate approaches using a simulated Space Station Remote Manipulator System (SSRMS). Also in support of tomorrow's berthing, ground controllers will use external ISS cameras tonight to inspect the Active Common Berthing Mechanism (ACBM) at the Node 2 Nadir location for damage and/or Foreign Object Debris (FOD). HTV-7 is scheduled to be captured at 7:00 AM CT tomorrow.

N21A4A Remote Power Control Modules (RPCM) Swap: Today the crew swapped the following RPCMs in order to restore power to downstream loads.

In May 2018, RPCM N21A4A-D RPC 13, which feeds Node 2 Shell Heater 5A, experienced a FET Controller Hybrid (FCH) failure. In order to recover the shell heater functionality, the crew swapped RPCM N21A4A-D with N21A4A-C since RPC 13 is no longer used in the N21A4A-C location.
In January 2015, RPCM N21A4A-A RPC 6, which powers General Luminaire Assembly (GLA) NOD2SD2, indicated Open with no trip indication; later troubleshooting verified this RPCM was also suffering from the FCH defect issue. In order to recover the GLA functionality, the crew swapped RPCM N21A4A-A with N21A4A-B since RPC 6 is not used in the N21A4A-B location.
On Board Training (OBT) Soyuz 54S Nominal Descent Drill Two: In preparation for their departure from the ISS on 4-October, the 54S Crew completed a second descent and landing drill earlier this morning. During this training, the crew ran the descent timeline, from Soyuz activation through post-landing activities, using the Neptune-ME training panel and reviewed operating features of the gas mixture supply system.

Japanese Experiment Module (JEM) Intermodular Ventilation (IMV) Flow Measurement: The crew used the Velocicalc tool to take measurements of airflow at the JEM Pressurized Module (JPM) IMV Overhead Aft Inlet, JPM IMV Starboard Aft Inlet, and JPM IMV Starboard Forward Outlet. By taking airflow measurements at different IMV diffusers, ground experts can verify that the IMV flow is sufficient to control carbon dioxide and humidity onboard ISS and that the IMV fans are operating in a good flow condition.
