Artemis II hiccup around 5 p.m. EDT, as an issue popped up with ground hardware that communicates with the flight termination system. The flight termination system allows engineers on the ground to send a signal to destruct the rocket if it were to veer off course during ascent, to protect public safety.
Issue resolved quickly.
Launch abort system hatch now closed.
Countdown continues.
⌛ 🤞
