A Jet Propulsion Laboratory (JPL) system called "Unified S-band", or USB, was selected for Apollo communications, which allowed tracking, ranging, telemetry, and voice to all use the same S band transmitter. Near-Earth tracking was provided by upgrading the same networks used for Mercury and Gemini.
This crewed flight was to have followed the first three uncrewed flights. After the fire which killed the AS-204 crew on the pad during a test and training exercise, uncrewed Apollo flights resumed to test the Saturn V launch vehicle and the Lunar Module; these were designated Apollo 4, 5 and 6. The first crewed Apollo mission was thus Apollo 7.

NASA currently has a group of flight controllers at the Johnson Space Center in Houston for the International Space Station (ISS). The Space Shuttle flight control team (as well as those for the earlier Gemini, Apollo, and Skylab programs) were also based there.
A launch 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.
The Apollo 17 project, which Feist began in 2009 as a part-time hobby and launched six years later [3] was the first real-time site published. It includes raw audio from the onboard voice and air-to-ground communication channels in Mission Control that had been released by NASA, and film that had been collected by archivist Stephen Slater in the UK.

Flight tracking enables travellers as well as those picking up travellers after a flight to know whether a flight has landed or is on schedule, for example to determine whether it is time to go to the airport. Aircraft carry ADS-B transponders, which transmit information such as the aircraft ID, GPS position, and altitude as radio signals.
Apollo 1, initially designated AS-204, was planned to be the first crewed mission of the Apollo program, [1] the American undertaking to land the first man on the Moon. It was planned to launch on February 21, 1967, as the first low Earth orbital test of the Apollo command and service module .
