Standing down today due to a standard ground system auto abort at T-1 min. Rocket and payload are in good health—teams are working towards tomorrow’s backup launch opportunity at 4:14 p.m. EDT, or 20:14 UTC.
Elon’s press call earlier:
Ground computers were at fault for today's #SpaceX launch abort from Pad 39A. Ground computers were also to blame for back to back aborts during the Intelsat 35e mission in July of last year.
