Quakesat is an Earth observation nanosatellite based on three CubeSats. It was designed to be a proof of concept for space-based detection of extremely low frequency signals, thought by some to be earthquake precursor signals. The science behind the concept is disputed.[2]

Mission

The students working on the project hope that the detection of magnetic signals may have value in showing the onset of an earthquake.[3] QuakeFinder, the company that put the satellites together, is from Palo Alto, California. They are gathering data on the extremely low magnetic field fluctuations that are associated with earthquakes to help better understand this area of study. The primary instrument is a magnetometer housed in a 2 ft (0.6 m) telescoping boom.

On 30 June 2003, deployment of Quakesat was alongside other university CubeSats and one commercial CubeSat. The launch occurred on a Rokot rocket from Russia's Plesetsk Cosmodrome.

The mission was planned to last one year, but ended up lasting 1 and a half year.[4]
