Space Shuttle

The US Space Shuttle or Space Transportation System (STS) has been making orbital flights since April 1981. The orbit is generally circular with altitude (differing by mission) anywhere from 200 km to over 600 km. The orbital plane is typically inclined (tilted) at 28.5 degrees, 39 degrees, 51.6 degrees, or 57 degrees depending on the mission.

Accurate Space Shuttle orbital information (including Keplerian elements) or other pertinent information is available in a current STSTLE message.

Mission monitoring by NASA TV is enjoyed by many. NASA TV is available by direct downlink by satellite and is provided by some cable TV providers. The audio portion is retransmitted locally by amateur radio operators and is available for monitoring by VHF/UHF scanner radios or other amateur radio equipment. The AMSAT Shuttle Retransmission list provides a current list of local NASA TV audio retransmission frequencies. The NASA Goddard Amateur Radio Club (GARC) also provides High Frequency (HF) Retransmissions of Shuttle audio. The tables below list Amplitude Modulation (AM) VHF and UHF frequencies used for spacecraft mission operations.

Some Space Shuttle missions carry 2 meter Frequency Modulation (FM) Amateur Radio Equipment for the Space Amateur Radio EXperiment (SAREX). The SAREX frequencies vary depending on whether or not the Shuttle will be docking with the Mir Space Station. The voice frequencies used for current SAREX missions are 145.800 MHz for the downlink and either 144.450 MHz or 144.470 MHz for the uplink for non-European stations. European stations should use 145.800 MHz for the downlink and 144.490 MHz for the uplink.
