“On the International Space Station, Expedition 50 Commander Shane Kimbrough and Flight Engineer Peggy Whitson of NASA floated outside the Quest airlock for a spacewalk to complete half of the work involved to swap out nickel-hydrogen batteries on the station’s truss with new lithium-ion batteries. Kimbrough and Whitson installed adapter plates on the truss and hooked up electrical cables as part of a complex robotics and spacewalk plan to shore up the station’s power supply for the future. It was the third spacewalk of Kimbrough’s career and the seventh for Whitson, who equaled the mark for most spacewalks by a woman previously set by NASA’s Suni Williams. Kimbrough will venture outside the station again on Jan. 13 with Flight Engineer Thomas Pesquet of ESA (European Space Agency) to continue and complete the battery work.”
“Kounotori 6, also known as HTV-6, is the sixth flight of the H-II Transfer Vehicle, an unmanned cargo spacecraft launched to resupply the International Space Station. It was launched at 13:26:47 UTC on 9 December 2016 aboard H-IIB launch vehicle from Tanegashima Space Center.
Major changes from previous Kounotori include: built-in payloads to demonstrate new technologies: SFINKS and KITE, reduction of primary batteries to 6 from previous 7, reduction of solar cell panels to 48 from previous 49, omission of some of navigation/position lights which were Earth-side when approaching to ISS, strengthened EP (Exposed Pallet) maximum payload to 1.9 t from previous 1.6 t to carry Li-ion batteries.
SFINKS (Solar Cell Film Array Sheet for Next Generation on Kounotori Six) will test thin film solar cells in space. KITE (Kounotori Integrated Tether Experiment) is an experimental electrodynamic tether (EDT). The tether is equipped with a 20 kg end-mass, and will be 700 m long when deployed. A maximum 10 mA current will run through the tether. Kounotori’s ISS rendezvous sensor will be utilized to measure how the end-mass moves during the test. The EDT experiment will be conducted following Kounotori 6’s departure from the ISS, and is to be held for a week. After the experiment, the tether will be separated before the spacecraft proceeds with the de-orbit maneuvers. The main objective of this experiment is the orbital demonstration of both extending an uncoated bare-tether, and driving electric currents through the EDT. These two technologies will contribute to gaining capabilities to remove space debris.
Cargo in the pressurized compartment includes 30 bags filled with potable water (600 liters), food, crew commodities, CDRA Bed (Carbon Dioxide Removal Assembly), TPF (Two-Phase Flow) experiment unit, PS-TEPC (Position-Sensitive Tissue Equivalent Proportional Chamber) radiation measurement instrument, ExHAM (Exposed Experiment Handrail Attachment Mechanism), HDTV-EF2 hi-def and 4K camera, new J-SSOD (JEM Small Satellite Orbital Deployer), and CubeSats (AOBA-Velox III, TuPOD which comprises two TubeSats (Tancredo-1 (pt) and OSNSAT), EGG, ITF-2, STARS-C, FREEDOM, WASEDA-SAT3). Cargo by NanoRacks includes TechEdSat-5, CubeRider, RTcMISS, NREP-P DM7, four Lemur-2. Additionally, the Blue SPHERES satellite of the MIT Space Systems Laboratory is being returned to the ISS for continued autonomous systems research. Cargo in the unpressurized compartment consists of six Lithium-ion batteries and their associated adapter plates to replace existing nickel-hydrogen batteries of the ISS. Since each of the new Li-ion battery has a capability equivalent to two of the current Ni-H batteries, the six new batteries will replace twelve old batteries, out of the 48 existing batteries of the ISS.”
“After saying farewell to the crew staying on the International Space Station and climbing into their Soyuz spacecraft on October 29, Expedition 49 Commander Anatoly Ivanishin of Roscosmos and Flight Engineers Kate Rubins of NASA and Takuya Onishi of the Japan Aerospace Exploration Agency, undocked from the orbital outpost, to begin their return trip to Earth. Ivanishin, Rubins and Onishi spent 115 days in space and 113 days aboard the orbital laboratory.”
“Loaded with more than 2.5 tons of supplies and science experiments, Orbital ATK’s Cygnus cargo craft arrived at the International Space Station Oct. 23 following its launch on a refurbished Antares rocket from the Wallops Flight Facility, Virginia Oct. 17. Expedition 49 crewmembers Takuya Onishi of the Japan Aerospace Exploration Agency and Kate Rubins of NASA captured Cygnus using the station’s Canadian-built robotic arm. Ground controllers then maneuvered Cygnus to the Earth-facing port of the Unity module where it was installed and bolted into place for a month-long stay.”
“The most recent series of payloads berthed with the International Space Station (ISS) Sunday morning onboard the Orbital ATK Cygnus capsule. Many of the investigations launched from Wallops Island, VA onboard the Antares rocket are sponsored by the ISS U.S. National Laboratory. The Center for the Advancement of Science in Space (CASIS) is tasked by NASA with managing and promoting research onboard the ISS National Laboratory for the benefit of Earth. Below provides a summary of the ISS National Laboratory-sponsored payloads delivered today:
CONTROLLED DYNAMICS LOCKER FOR MICROGRAVITY EXPERIMENTS ON ISS
Controlled Dynamics
Principal Investigator: Dr. Scott Green
Dr. Green and his team have developed a hardware platform that will provide research payloads with a “controlled dynamic acceleration environment”—in other words, a technology that will dampen fluctuations/disturbances in the microgravity environment that occur onboard moving spacecraft. This technology promises to attract a new class of research experiments and private funding aimed at exploiting this controlled acceleration environment in microgravity, which has the potential to improve space experiments in crystallization; fluid physics; cell, tissue, and plant culturing; and other studies that require precise control of motion. This investigation stems from a CASIS grant supporting enabling technology development onboard the ISS National Lab.
NANORACKS BLACK BOX
NanoRacks, LLC
Principal Investigator: Mary Murphy
NanoRacks Black Box is a key part of NanoRacks’ next-generation ISS platforms. This new hardware is specially designed to provide near-launch payload turnover of autonomous payloads while providing advanced science capabilities for customers, including the use of robotics, new automated MixStix, and NanoLab-style research. OA-5 provides the first technology demonstration mission to test the NanoRacks Black Box platform, NanoRacks’ own payload hardware, and customer technology demonstration experiments. Technology demonstration payloads onboard OA-5 include multiple education-focused experiments, one of which features a partnership between Valley Christian High School in California and Microsoft, in which students will leverage the Microsoft Windows 10 IoT (internet of things) platform to run experiments on a cell phone motor to test the behaviors of different metals and materials in microgravity environments with status and magnetic forces.
NANORACKS EXTERNAL DEPLOYER
NanoRacks, LLC
Principal Investigators: Conor Brown and Henry Martin
NanoRacks provides opportunities for CubeSat deployment from Cygnus after the vehicle departs from the ISS. The NanoRacks deployer is installed on the exterior of the Cygnus service module, and after completion of its primary ISS resupply mission, Cygnus is intended to move into a higher orbit, and then deploy small satellites. Four satellites are part of the OA-5 mission intended to launch from Cygnus in partnership with the space-based data company, Spire. Spire’s solutions offer organizations near-real-time insights into weather and climate, shipping and supply chain, and maritime domain awareness. Ships carry 90% of global trade over the oceans, but the ships and those that rely on them are open to risks caused by delays, piracy, poor data for search and rescue operations, and incomplete data sets. The ship tracking payload reduces those risks by relaying critical metadata about oceangoing vessels to a network of ground stations. The weather observation payload gathers incredibly accurate temperature, pressure, and humidity data by recording and processing signals from GPS satellites as they “bend” through the Earth’s atmosphere. The data is fed into weather models, where it provides large improvements to short- and medium-term forecasts. This mission will incrementally increase Spire’s satellite constellation, providing additional coverage from a mid-inclination orbit.
SOLIDIFICATION USING A BAFFLE IN SEALED AMPOULES (SUBSA) FURNACE
NASA Marshall Space Flight Center
Material melt-growth experiments have been difficult to run in the space environment because there is just enough residual micro-acceleration (g-jitter) to produce natural convection that interferes with the structure and purity of the material. This convection is responsible for the lack of reliable and reproducible solidification data and, thus, for gaps in solidification theory. The Solidification Using a Baffle in Sealed Ampoules (SUBSA) experiment tested an automatically moving baffle (driven by melt expansion during freezing) that was designed to reduce thermal convection inside an ampoule to determine whether the baffle significantly reduces convection. Ground studies showed that the baffle reduces the movement of the material during its liquid phase, making the process easier to analyze and allowing more homogenous crystals to form. The key goal of SUBSA was to clarify the origin of the melt convection in space and to reduce the magnitude to the point that it does not interfere with the transport phenomena. This mission will provide updates to the hardware onboard the ISS to include modifications to the furnace and inserts to ensure future investigations run nominally.”
“Hurricane Nicole is currently a strong tropical cyclone moving away from the British Overseas Territory of Bermuda. It is the first major hurricane to directly impact or make landfall on the island since Hurricane Fabian in 2003. The fourteenth named storm, sixth hurricane and third major hurricane of the active 2016 Atlantic hurricane season, Nicole formed in the central Atlantic on October 4. The small, slow-moving storm defied forecasts by steadily organizing in spite of strong wind shear, and it rapidly intensified to a Category 2 hurricane on October 7. The wind shear finally took its toll by October 8, reducing Nicole to a weak tropical storm, but more favorable conditions allowed the cyclone to reintensify into a hurricane a couple days later. The storm’s approach to Bermuda forced schools, businesses, and government offices to close, while flight, bus, and ferry services were interrupted. On October 13, the eye of Category 3 Hurricane Nicole passed over Bermuda, producing damaging winds.”
“On Sept. 6, after bidding farewell to the crew remaining aboard the International Space Station, Expedition 48 Commander Jeff Williams of NASA and Soyuz Commander Alexey Ovchinin and Flight Engineer Oleg Skripochka of Roscosmos undocked from the orbital outpost to begin their return trip to Earth. They spent 172 days aboard the ISS, conducting research and operational work in support of the station.”
