minus-square@Ghystelink3•2 months agoThey fire the engines several seconds before T-0 and it’s ready to jump off the pad at full thrust as soon as the clamps release. Soyuz does the same. Also solid fuel boosters don’t know any word other than GO once lit.
minus-square@[email protected]linkfedilink2•2 months agoDid they change their procedure? AFAIK Ariane 5 had their ignition on zero (in contrast to US launches who famously had their liftoff at zero)…
