#NASA 📆 July 12, 2023 #DSS23 started in 📆 February 2021 at the Goldstone, #California, #DSN Complex (with #OpticalCommunication
capabilities, which will be critical to communicate with #astronauts 👨🚀👩🚀 traveling to #Mars 🔴). NASA cannot use #RadioFrequency communications to carry higher data rates like those required for Mars without increasing
the size of its antennas 📡 or power of its radio transmitters. Therefore, the Agency is developing #optical communications (use
of light as a means of transmitting information through #lasers) https://oig.nasa.gov/docs/IG-23-016.pdf

Something like the SV1AFN VNA test PCBs but as an open-source design that I can tweak a bit for different components. Also the SV1AFN design is shunt only.

Maybe it's the chance to finally work some contacts with this mode. Anybody planning to participate? I will most likely do.
