    Bit annoying that they’re more specific about latency than bandwidth. The laser had lower latency than broadband, but I want to know if the laser had enough bandwidth to stream the video.

      Lower latency than broadband…?

      If you’re getting >100s ping times you might want to have them come out to check your lines.

        Something tells me you’re not getting sub 100ms latency with broadband over 19 million miles

          I mean, if their point was that a straight-shot laser had lower point-to-point latency than a system with a bunch of non-direct links, intermediate switches, routers, mix of copper and fiber, etc… Well, no kidding.

          Didn’t say anything about 100ms though. I was guessing maybe they read 100ms though. Still not sure what the point was.

      "The video was then downloaded and each frame was sent to NASA’s Jet Propulsion Laboratory in Southern California, where it was played in real time. "

      It sounds like it. Laser comm can have some insanely high data rates due to the high frequency of the radiation.
