.......The countdown for a planned launch of a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida automatically aborted in the last second before liftoff Sunday after an on-board computer detected unexpected data during an engine power check.
The dramatic last-second abort occurred at 9:22 a.m. EDT (1322 GMT) Sunday, moments after the Falcon 9’s main engines ignited on launch pad 39A. A member of launch team announced engine start and liftoff. A second later, she said: “Disregard. We have an abort.”
This was an instantaneous launch opportunity Sunday, so the abort meant SpaceX had to scrub the day’s launch attempt........
SpaceX tweeted later Sunday morning that a “standard auto-abort triggered due to out of family data during engine power check.”
Last-second aborts after engine ignition during SpaceX countdowns are rare, but they have happened before on several occasions. On the Falcon 9’s inaugural launch in June 2010, SpaceX aborted the countdown just before engine start and tried again the same afternoon, resulting in a successful mission that reached orbit.
The company said it will announce a new target launch date once the schedule is confirmed with the U.S. Space Force’s 45th Space Wing, which runs the Eastern Range that oversees all launch activity at Cape Canaveral.
An updated launch weather forecast released by the 45th Space Wing on Sunday suggested the next launch opportunity for the Falcon 9 rocket might be Wednesday at 8:21 a.m. EDT (1221 GMT).
The weather forecast shows an 80 percent chance of acceptable conditions for launch Wednesday morning with scattered clouds, light easterly winds, and a temperature of around 70 degrees Fahrenheit. The primary weather concern is with cumulus clouds........
