The PhoneSat project was selected by Popular Science magazine as one of eleven "Best of What's New" in the aerospace category in 2012. Control software and firmware was made open source whenever possible. The chassis is a single standard CubeSat bus and sized 10 cm × 10 cm × 10 cm (around 4 inches per side). The construction cost of the first version of PhoneSat satellite was reported to be US$3,500 and that of the second version was reported to be below US$7,000.
When the project started, a typical smartphone had a faster CPU and more memory than the average satellite, one or two cameras, multiple acceleration and rotation sensors, a compass, a GPS receiver, radios, and a Li-Ion battery, all of which had benefited from significant research and development efforts and economy of scale in the telecommunications industry to reduce cost. This project is part of NASA's Small Spacecraft Technology Program and was started in 2009 at NASA Ames Research Center ( Moffett Field, California). PhoneSat is an ongoing NASA project of building nanosatellites using unmodified consumer-grade off-the-shelf smartphones and Arduino platform and launching them into Low Earth Orbit.
