Today I learned that the Ingenuity drone copter twirling about on Mars communicates with the Perseverance rover using 900MHz Zigbee radios. Not Wi-Fi, GSM, or something exotic like fission-powered lasers or space algae, but the same consumer tech you use to turn on a Philips Hue lightbulb.
According to Richardson, Zibee is the ideal wireless protocol to transfer telemetry data between NASA’s Perseverance rover and the semi-autonomous flying drone. “Looking at really extreme environments, like Mars, it’s good to have a very lightweight purpose-built standard,” said…
