Las imágenes de satélite son como los mapas: están llenas de información útil e interesante, siempre y cuando tengas una clave. Éstas nos pueden mostrar cuánto ha cambiado una ciudad, cuán bien están creciendo nuestros cultivos, dónde arde un fuego o cuando se acerca una tormenta. Para revelar la riqueza de información en una imagen […]
USOS EVA and Orbital Status: A Program decision was made to pursue USOS EVAs on December 21st, 23rd, and 25th (if required) in order to repair the ETCS Loop A Pump Module. The EVAs will be carried out using EMUs 3010 and 3011. Orbital launch will be delayed until after the beta cutout in January. …
Every month we offer a puzzling satellite image here on Earth Matters. Every month someone seems to figure it out quickly. We are feeling like it is time to throw down some gauntlets. The December 2013 puzzler is above. Your challenge is to use the comments section to tell us what the image shows, what part of […]
External Thermal Control System (ETCS) Loop A Status: ETCS Loop A is still operating without full temperature control. All Loop A Interface Heat Exchangers (IFHX) remains bypassed and isolated, preventing internal heat rejection on loop A. ETCS Loop B continues to operate nominally. MCC-H continues to perform tests on ETCS Loop A to determine if …

Orbital 1 Launch Status: To allow additional time for ground specialist to continue to work the ETCS Loop A issues the Orb-1 Launch date has changed from December 18th (CST) to December 19th (CST). External Thermal Control System (ETCS) Loop A Status: ETCS Loop A is operating, however due to a bias on the flow …
Watch closely and you will see the International Space Station, or ISS, cross the disk of the gibbous moon. Traveling at more than 17,000 mph, the ISS occasionally appears to pass in front of the moon or sun. These events go largely unnoticed, however, because viewers have to be along a very narrow path on Earth, …
External Thermal Control System (ETCS) Loop A Status: Overnight ground specialist power cycled the ETCS Loop A Pump Control Valve Package (PCVP), which includes the Flow Control Valve (FCV), in an attempt to correct the FCV position error. The ETCS has been repowered, however the FCV position error has not been corrected. ETCS Loop A …
How do you launch a satellite into space? It isn’t easy. The simple answer would be to build one, place it on a rocket, and shoot it off. But building and launching satellites turns out to be exceedingly complicated things to do. They’re highly complex machines, requiring profoundly precise levels of craftsmanship, not to mention […]
It’s that Time of Year Monarch butterflies congregate in central Mexico every winter. Sandhill cranes stop at a small section of the Platte River in Nebraska every spring. And earth and planetary scientists congregate in San Francisco each December. More than ten thousand people converged on Moscone Center this week for the the fall meeting […]
