NASA has sent three Google Nexus One, Android Smartphones in orbit around the Earth so that they can become “low-cost” satellites.
The pictures of the earth taken by these satellites will then be sent to earth. NASA says this as it will publish photographs on the site phonesat.org . Nasa has slightly modified Nexus phones for the operation. They have added a lithium-ion battery and an external radio transmitter that is powerful enough to send data packets from space. Finally, the ability of these phones to send or receive calls has been disabled.
