Engineers also inspected PPRV B by borescope and didn\u2019t note any visual inconsistencies. <\/p>\n To doublecheck the valve is causing the issue, United Space Alliance engineers connected Ground Support Equipment (GSE) directly to the valve, which did show that the valve poppet is leaking, confirming the earlier results that pointed to the valve as the culprit of failed leak tests. <\/p>\n Once the replacement valve has been installed into Endeavour, a reset will be conducted, ahead of further leak checks, which \u2013 providing they are successful \u2013 will allow NASA to pick up the launch countdown, on time, Saturday evening.<\/p>\n The only potential problem to this process at present is the weather, as a thunderstorm warning for the local area was produced Thursday morning. If KSC is alerted to lightning strikes, workers will have to leave the launch pad, delaying continued operations with very little time to spare.<\/p>\n So far, the weather has not affected operations, and the valve was successfully installed into Endeavour before noon \u2013 ahead of schedule.<\/p>\n Further updates will follow \u2013 refer to the live pages on L2 and STS-118 sections (forum).<\/p>\n L2 members<\/font>: All documentation \u2013 from which the above article has quoted snippets \u2013 is available in full in the related L2 sections, updated live.<\/em><\/p>\n **STARLIGHT: NEW STS-117 MISSION REVIEW MUSIC VIDEO**<\/font><\/em><\/font> <\/em><\/font><\/p>\n **ROCK YOU LIKE A HURRICANE: BRAND NEW STS-117 MISSION REVIEW MUSIC VIDEO \u2013 AS SEEN BY THE STS-117 CREW!!**<\/font> -. **NASASpaceflight.com Job Opportunities**<\/em><\/font> <\/font><\/em><\/p><\/p>\n","protected":false},"excerpt":{"rendered":" So far so good, as engineers move into the next phase of troubleshooting a cabin leak on Endeavour, which is still on the timeline to enable an on-time start to the STS-118 launch countdown Saturday evening.
