I asked the question had anyone got the frequency for the Artemis trip to the moon. (for those who don’t understand the question to hear comms from the space ship to NASA inflight to and from the moon)
With the odd helpful reply i went on the hunt and found this info
While you won’t be able to “tune in” with a standard handheld radio to hear the astronauts chatting, dedicated amateur radio operators with specialized equipment are actively preparing to track and receive signals from the Orion spacecraft.
The primary communication for Artemis II happens on the S-band (2.2–2.3 GHz) and via a new high-speed Optical (laser) Communications System (O2O).
-
Public Access: You cannot hear them directly on standard VHF/UHF ham frequencies. However, many ham radio clubs (like those at NASA’s Johnson and Goddard Space Centers) often rebroadcast mission audio on local repeaters (e.g., 146.640 MHz in Houston or 147.450 MHz in Maryland) during major mission phases.
-
Encryption: Much of the modern voice and data telemetry is digital and encrypted for security and mission integrity, meaning even if you “catch” the signal, it would sound like white noise without a NASA-authorized decoder.
-
To participate, operators typically use large satellite dishes (often 1.2 meters to 4.5 meters or larger) and Software Defined Radios (SDRs) capable of receiving the S-band spectrum (specifically around 2210.5 MHz).
-
The Crew: Three of the four Artemis II astronauts—Reid Wiseman (KF5LKT), Victor Glover (KI5BKC), and Jeremy Hansen (KF5LKU).
-
If you have a 2.4 GHz dish and an SDR, you can try to “see” the signal spike on a waterfall display as Orion travels to the Moon. If you just want to hear the crew, your best bet is to listen to the NASA TV live stream or find a local ham repeater that is rebroadcasting the audio feed.
