A bright fireball event occurred on Dec. 17 at 8:20:40 PM CST. It started out 52 miles above I-24 just south of Manchester, TN and moved to the northwest at 50,000 mph. The all sky camera lost track of it at an altitude of 23 miles just to the northwest of Shelbyville. Below is a …
External Thermal Control System (ETCS) Loop A Status: Following yesterday’s S1-1 MDM software patch, Flight Controllers continued to perform characterization tests on ETCS Loop A to regain fine temperature control of ETCS loop A. The Node 2 Moderate Temperature Loop (MTL) IFHX is still isolated from ETCS Loop A, resulting in half of the loads …
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. …
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 …
External Thermal Control System (ETCS) Loop A Status: ETCS Loop A is still operating without full temperature control. The 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 performing tests on ETCS Loop A to determine if they …
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 …
External Thermal Control System (ETCS) Loop A Status: ETCS Loop A is still operating without full temperature control. The Loop A Interface Heat Exchangers (IFHX) are still bypassed and isolated, preventing internal heat rejection on loop A. ETCS Loop B continues to operate nominally. Due to the loss of heat rejection for the N2 Moderate …
External Thermal Control System (ETCS) Loop A Shutdown: This morning, ETCS Loop A shut down due to under temperature Fault Detection Isolation and Recovery (FDIR). Ground specialist have repowered the Loop A pump and is currently cooling external loads at this time. However, the Flow Control Valve (FCV) is not operating as expected and the Loop …
