    Our connectivity to mars is on the order of 12kbps, presumably better for the moon. My other question would be whether this is due to the need to radiation harden stuff? We were de…

    I now have ads on my expensive Samsung. Teaches me right for not heeding the advice and getting as dumb a TV as possible. I should not need to run a PiHole to deal with this.
