On Thursday, May 10th, 2018, SpaceX attempted a launch of the first Falcon 9 block V rocket carrying Bangabandhu-1 however the countdown was stopped at t-58 seconds and the launch was scrubbed for 24 hours. Do we know what caused the launch abort sequence to be initiated?

    $\begingroup$ So far only this tweet: "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." - which is ofc not enough for an answer. $\endgroup$

1 Answer 1


The Flight Computer checked everything, and noticed an abort signal in a piece of ground equipment, due to a bad state from a prior test. They have fixed the problem to not happen again.

This is from the livestream of the second launch attempt.
