Pocket Sized Sattelites for Asteroid Detection


We’ve seen kicksats before, small pocketable single board satellites designed to orbit Earth. At this year’s Maker Faire, the team behind these kicksats has a new plan: using them to determine the orbits of earth-passing asteroids and hopefully not giving us any forewarning of our imminent extinction.

Instead of simply orbiting Earth, the new plan for these kicksats is to deploy them into the path of an oncoming asteroid such as Apophis so the radio transmissions from each satellite can pinpoint where exactly the asteroid is, something Earthbound optical and radio telescopes struggle with.

Despite the small size, the hardware on each kicksat is pretty impressive; each mini satellite has a solar cell on each side, a low-power MSP430 microcontroller with a radio module, and a few sensors. The system is designed so anyone can pick up the telemetry from these satellites with a small Yagi antenna and an RTL SDR TV tuner dongle.

An impressive bit of kit, but if holding a satellite or asteroid in your hand is more your thing, the same team behind the kicksat put up a whole bunch of 3D models of asteroids and space probes. They’re actually quite impressive when they’re printed out.
