If you follow Earth and climate science closely, you may have noticed that the media is abuzz every December and January with stories about how the past year ranked in terms of global temperatures. Was this the hottest year on record? In fact, it was. The Japanese Meteorological Agency released data on January 5, 2015, that showed 2014 was […]
Coarsening in Solid Liquid Mixtures (CSLM)-4: Virts set up and began processing on the first of six CSLM-4 runs. Over the next week, six CSLM sample processing units (SPUs) will be processed in the Microgravity Science Glovebox (MSG) and prepared for return on SpaceX-5. For each run, the crew will configure valves and connections to …
Ground controllers have completed troubleshooting work after last week’s false alarm indicating an ammonia leak. Heat exchangers and thermal control systems on the U.S. side of the International Space Station have been recovered and reintegrated and are operating in excellent shape. Commander Barry Wilmore was scrubbing cooling loops on a U.S. spacesuit when he heard …
External Thermal Control System (ETCS) Loop B Recovery Status: Over the weekend, ground teams finished repressurizing and recovering ETCS Loop B and the systems which were deactivated as a result of Wednesday’s safeing response. The Loop B Interface Heat Exchangers (IFHX) have been reintegrated, which allows internal heat rejection on Loop B. Cardio Ox: Crew …
NASA's Soil Moisture Active Passive spacecraft has been attached to the top of the United Launch Alliance Delta II rocket that will deliver it to orbit. Preparations for the Jan. 29 launch are on schedule at Vandenberg Air Force Base in California. Payload carriers containing small satellites called CubeSats are being attached to the rocket's …
NASA and NOAA announced today that 2014 brought the warmest global temperatures in the modern instrumental record. But what did the year look like on a more regional scale? According to the Met Office, the United Kingdom experienced it warmest year since 1659. Despite the record-breaking temperatures, however, no month was extremely warm. Instead, each month (with the exception of […]
External Thermal Control System (ETCS) Loop B Recovery Status: Ground teams continue working towards incrementally re-pressurizing ETCS Loop B. Last night’s re-pressurization resulted in a 1% decrease in Ammonia Tank Assembly (ATA) tank quantity. Ground teams are targeting a total of 7% decrease (0.63 c.f. NH3) before a Loop B restart is attempted. The Loop …
External Thermal Control System (ETCS) Loop B Recovery Status: Ground teams are methodically working towards repressurizing and recovering ETCS Loop B and the systems which were deactivated as a result of yesterday’s safeing response. The Loop B Interface Heat Exchangers (IFHX) are still bypassed and isolated, preventing internal heat rejection on Loop B. Due to …
The International Space Station residents were back at work Thursday after an ammonia leak indication sent the crew over to the Russian segment. Flight controllers determined there was no leak and NASA managers allowed the crew to resume normal activities and open the U.S. segment back up. This week, the orbital residents kicked off several …
