Launch Feb. 2026 {NET Feb.5} Any thoughts on possible HF Comms?
One of the new additions for Artemis II’s Orion spacecraft is the Optical Communications System O2O hardware, a DTO (detailed test objective) flying on Artemis II. The Optical Communications System2 is an infra-red laser based communications system that has been in development since 2013 by NASA in partnership with the Massachusetts Institute of Technology’s Lincoln Laboratory.
wideband polylingual terminals use
software defined radios to enable
similar roaming capabilities in space,
empowering spacecraft to move
between both government and
commercial frequencies.
Terminal Details
• SWAP: 24 x 24 x 17 inches, ~23kg weight,
peak power 200 watts
• Operational Frequency Coverage: 17.7 GHz-
23.55 (Forward) and 27 GHz-31 GHz (Return)
• EIRP: 46.21 dBW (Minimum)
• G/T: ~6dB/K
• Waveforms: DVB-S2, CCSDS TDRSS
• Data Rates: up to 90 Mbps (Forward)
and up to 375 Mbps (Return)
• Future Data Rates: up to 490 Mbps
(Forward) and 1 Gbps (Return)
I have no need for a history lesson. Im asking about flight's from 2022-2026 missions. My best guess 12.222 USB. HOMEPLATE FLA. has had recent HF radio comms. Will be monitoring each day. Worth it.HF? Apollo didn't use HF, so I wouldn't expect Artemis to do so.
If you are interested, look up Curious Marc on YouTube. He has a whole series about restoring Apollo communications equipment. The technology they used in the 1960s is fascinating.
Only support aircraft. No direct HF comms.Im asking about flight's from 2022-2026 missions. My best guess 12.222 USB. HOMEPLATE FLA. has had recent HF radio comms. Will be monitoring each day.
Well thanks but i still have a desire to monitor HOMEPLATE out of Florida during the flight. HF will never let you down.Only support aircraft. No direct HF comms.
