Alaunch status check, also known as a "go/no go poll" and several other terms, occurs at the beginning of an American spaceflight mission in which flight controllers monitoring various systems are queried for operation and readiness status before a launch can proceed. For Space Shuttle missions, in the firing room at the Launch Control Center, the NASA Test Director (NTD) performed this check via a voice communications link with other NASA personnel. The NTD was the leader of the shuttle test team responsible for directing and integrating all flight crew, orbiter, external tank/solid rocket booster and ground support testing in the shuttle launch countdown. The NTD was also responsible for the safety of all personnel inside the pad after external tank loading, including the flight crew, about 10 go/no go reports. He reported to the Launch Director, who has another about 5 go/no go reports.[1] The Launch director declares if a mission is go for launch.
