The topic of climate change inspires a lot of debate. At NASA, it has also inspired a lot of science. NASA scientists examine the Earth’s climate and how it is changing – gaining knowledge (or insight?) through decades of satellite observations, powerful computer models and expert scientific analysis. Over the course of this month, these […]
Extravehicular Mobility Unit (EMU) Troubleshooting: On Saturday, Flight Engineer (FE)-3 Cassidy and FE-6 Nyberg performed a removal and replacement (R&R) of EMU 3011 condensate water relief valve (item 134) and associated filter. Crew then performed an EMU screening test and discovered that the water crossover anomaly was still present. They then proceeded with the gas …
Early Wednesday morning, at 3:27:20 AM Eastern Time, a piece of an asteroid, about 2 feet in diameter and weighing over 100 pounds, entered Earth’s atmosphere above the Georgia/Tennessee border, just south of Cleveland. The meteor was moving northeast at 56,000 miles per hour, and began to break apart north east of Ocoee, at an …
Ocular Health Ultrasound Eye Imaging: Flight Engineer (FE)-6 Nyberg and FE-5 Parmitano performed their Flight Day (FD) 90 session of the Ocular ultrasound experiment. The data gathered in these sessions will be used to identify changes in globe morphology, including flattening of the posterior globe, and document optic nerve sheath diameter (ONSD), optic nerve sheath …
BioLab Microscope D&C Cassette Troubleshooting: Following yesterdays successful Part A of the Microscope troubleshooting and initialization, Flight Engineer (FE)-5 Parmitano continued with Part B of the troubleshooting by extracting the BioLab HM drawer, installing a Microscope cassette, verifying the correct fit of the cassette, and close up of the microscope. The ground subsequently performed a …
Robonaut Operations: Flight Engineer (FE)-3 Cassidy deployed and attached the Robonaut Taskboard and Robonaut in the U.S. Lab for ground commanded operations. Today the ground performed a checkout of the operating software which involved Robonaut performing large and small arm and finger motions while the ground monitored the generated forces. The purpose of Robonaut is …
The Nuts and Bolts of Designing a Color Palette Knowing what makes a good palette for visualization, how to find and apply good examples, or create one from scratch? In my mind the best place to start is Color Brewer. Cynthia Brewer’s tool is popular for a reason: it explains the theory behind palette design, […]
Extravehicular Mobility Unit (EMU) Troubleshooting: Flight Engineer (FE)-3 Cassidy performed a checkout of the Water Separator Screen on EMU serial number 3011. The checkout was terminated early once expected water was observed leaking from behind the helmet pad. During US Extravehicular Activity (EVA) 23, an excessive amount of water accumulated in the back of the …
Mobile Servicing System (MSS) Status and Operations: Saturday, Robotics Ground Controllers powered up the MSS and used the Special Purpose Dexterous Manipulator (SPDM) on the Space Station Remote Manipulator System (SSRMS) to remove the Utility Transfer Assembly (UTA) from the H-II Transfer Vehicle (HTV) 4 Exposed Pallet (EP) and to install it on the SPDM …
A special congratulations to Cyndy Hunting for being our first reader to work out that the August puzzler showed Garden and Hog islands in northern Lake Michigan. After 19 puzzlers, this was the first time the correct answer came in as a comment on our Facebook page. Just a few hours after Cyndy nailed the […]
