Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI)-2 Auto-Stop Transition: On Sunday, ground teams received notification that MELFI-2 in the Japanese Experiment Module (JEM) transitioned to Auto-stop. The Brayton Motor powered off, and the rack maintained power and good Low Temperature Loop (LTL) flow. The Cold Stowage team noted that the way the MELFI monitoring software is coded that the software may pick up on an Auto-Stop condition and take action before it’s reported in telemetry that is broadcast to the ground. Based on the state of the rack prior to the Auto-Stop, Cold Stowage is confident that is what happened. Due to all other rack parameters being in a good state, the Brayton Motor was repowered and the total time for the Brayton Motor to be off was 1 hour 16 minutes 5 seconds. Body Measures: FE-6, with the assistance of FE-5 as the operator, conducted a Body Measures data collection session. The crew configured still cameras and video, then collected the Neutral Body Posture video and stow the equipment. NASA is collecting in-flight anthropometric data (body measurements) to assess the impact of physical body shape and size changes on suit sizing. Still and video imagery is captured and a tape measure is used to measure segmental length, height, depth, and circumference data for all body segments (chest, waist, hip, arms, legs, etc.) from astronauts before, during and after their flight missions. Fine Motor Skills (FMS): Both FE-5 and FE-6 performed their weekly FMS sessions. The crew each performed a series of interactive tasks on a touchscreen tablet were completed for the Fine Motor Skills investigation. This investigation is critical during long-duration space missions, particularly those skills needed to interact with technologies required in next-generation space vehicles, spacesuits, and habitats. The crewmember’s fine motor skills are also necessary for performing tasks in transit or on a planetary surface, such as information access, just-in-time training, subsystem maintenance, and medical treatment. Microgravity Science Laboratory (MSL) Sample Cartridge Assembly (SCA) Exchange: The crew changed out the SCA in the Solidification Quenching Furnace (SQF), removing the calibration cartridge and inserting the first test sample. Ground teams will initiate the runs next week. The Batch-2b of the Materials Science Laboratory Sample Cartridge Assemblies serves two projects investigating how different phases organize in a structure when metallic alloys are solidified. The project Metastable Solidification of Composites (METCOMP) studies the phase formed by the reaction of the remaining liquid phase with an already formed solid, to form a second solid phase on cooling. For this purpose, Bronze (Copper-Tin Alloys) of different compositions will be processed. The other project, Solidification along a Eutectic path in Ternary Alloys (SETA), looks at how two phases that form together organize into lamellar, or fibre, structures when cooling Aluminum (Copper-Silver Alloys). Both projects will provide benchmark samples that will enable to test numerical models that aim to predict these structures. Eli Lily Hard to Wet Surfaces: FE-6 charged batteries in support of the Hard to Wet Surfaces experiment. After the battery charging, the crew verified the setup of the camera and flash that will be used in the experiment run starting tomorrow. In chemistry, wetting refers to spreading of a liquid over a solid material’s surface, and is a key aspect of the material’s ability to dissolve. The Hard to Wet Surfaces (Eli Lilly-Hard to Wet Surfaces) investigation studies how certain materials used in the pharmaceutical industry dissolve in water while in microgravity. Results from this investigation could help improve the design of tablets that dissolve in the body to deliver drugs, thereby improving drug design for medicines used in space and on Earth. Hatch Seal Inspection: FE-5 cleaned and inspected the COL, N2 port, N2 Stbd, A/L, N2 Stbd, JLP, JPM Stbd, JPM Zenith and PMM hatch seals, hatch plate sealing surface and hatch handle mechanism for FOD or damage. This is standard preventative maintenance performed every 180 day. Space Station Remote Manipulator System (SSRMS) Latching End Effector (LEE) Survey: The SSRMS was powered up and maneuvered to allow for an inspection of the LEE B using the new High Definition cameras.

50000 Kilometers over the Sun
What's happening at the edge of the Sun? Although it may look like a monster is rampaging, what is pictured is actually only a monster prominence -- a sheath of thin gas held above the surface by the Sun's magnetic field. The solar event was captured just this past weekend with a small telescope, with the resulting image then inverted and false-colored. As indicated with illustrative lines, the prominence rises over 50,000 kilometers above the Sun's surface, making even our 12,700-diameter Earth seem small by comparison. Below the monster prominence is active region 12585, while light colored filaments can be seen hovering over a flowing solar carpet of fibrils. Filaments are actually prominences seen against the disk of the Sun, while similarly, fibrils are actually spicules seen against the disk. Energetic events like this are becoming less common as the Sun evolves toward a minimum in its 11-year activity cycle. via NASA http://ift.tt/2d5Ewlt
