SpaceX delays fourth flight attempt by a few days SpaceX has delayed its fourth launch attempt of its Falcon I rocket after the commercial space start-up decided to replace a part in the rockets second stage engine.
Static Fire test The static fire took place on Saturday (20 Sep 2008, CA time), as expected, and no major issues came up. However, after a detailed analysis of data, we decided to replace a component in the 2nd stage engine LOX supply line. There is a good chance we would be ok flying as is, but we are being extremely cautious. This adds a few extra days to the schedule, so the updated launch window estimate is now Sept 28th through Oct 1st
As mentioned in my update last month, we do expect to conduct a launch countdown in late September as scheduled. Having said that, it is still possible that we encounter an issue that needs to be investigated, which would delay launch until the next available window in late October. If preparations go smoothly, we will conduct a static fire on Saturday and launch sometime between Tuesday and Thursday (California time). Source SpaceX
