Each month, Earth Observatory offers up a puzzling satellite image here on Earth Matters. The September 2013 puzzler is above. Your challenge is to use the comments section to tell us what part of the world we are looking at, when the image was acquired, and why the scene is interesting. How to answer. Your […]
Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions (InSPACE)-3 Experiment Runs: Flight Engineer (FE)-6 Nyberg completed runs 23 through 26 out of a total of 42 runs planned as part of this experiment series. InSPACE-3 studies the behavior of magnetic colloidal fluids which transition to a solid-like state by the formation and cross-linking of …
Note: See the comment thread for an archive of questions and answers related to this event. Do you have questions about how NASA measures, models, and visualizes our changing climate? Here’s your chance to ask them directly. Earth Observatory is hosting a climate Q & A with NASA scientists at 2 pm EDT on Wednesday, […]
In Flight Maintenance (IFM) Crew Quarters (CQ) Cleaning – Flight Engineer (FE)-6 Nyberg cleaned the overhead CQ intake and exhaust ducts, fan and flow sensors. This routine maintenance was performed in preparation for the arrival of new ISS crewmembers later this month. Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions (InSPACE)-3 Experiment Runs: FE-5 …
34S Soyuz Undock & Landing: Soyuz 34S undocked from the ISS Mini-Research Module (MRM)-2 bringing Commander (CDR) Viogradov, Flight Engineer (FE-2) Misurkin, and FE-3 Cassidy back to earth. Prior to undocking, the crew performed leak checks on the vestibule, suits, and hatch between the descent module and the habitation module. The undock command, which initiated …
Monday, Sept 9 at 8:18 PM Central Time, a baseball size fragment of a comet entered Earth’s atmosphere above Alabama, moving southwest at a speed of 76,000 miles per hour. At such speeds, fragile cometary material will not last long. Just 3 seconds after hitting the atmosphere, the meteor disintegrated 25 miles above the town …
References and Resources for Visualization Professionals The previous posts are my personal take on using color in visualization. I hope my perspective is useful, but it’s primarily a synthesis of the work of others. Here’s a list of the sources that inspired and informed this series. If you don’t have the time or the inclination […]
LAB Robotics Work Station (RWS) Loss of Communication (LOC): Shortly after midnight Friday night the C&C Multiplexer/Demultiplexer (MDM) lost comm with the (primary) LAB RWS. Ground teams performed troubleshooting over the weekend which resulted in 5 failed power cycles, however that was followed by 4 successful power cycles. Preliminary analysis indicates a possible intermittent hardware …
Spinal Ultrasound Scan Operations: Flight Engineer (FE)-6 Nyberg with FE-5 Parmitano’s assistance, performed her second of three Spinal Ultrasound Scan sessions for her stay onboard the ISS. This investigation aims to characterize microgravity-associated spinal alterations during and after spaceflight using in-flight ultrasound. Results from this research will provide data to enhance crew health for long duration …
Node 3 Carbon Dioxide Removal Assembly (CDRA) Air Selector Valve (ASV) 103 Remove and Replace (R&R): Flight Engineer (FE)-3 Cassidy performed an R&R of the Node 3 CDRA ASV. The valve had failed to reach its commanded position (position B) on GMT 214 and 228. Telemetry indicated that the valve had stalled in an intermediate …
