Yesterday, SpaceX launched 103 of the world’s smallest satellites into orbit for testing. These micro satellites weigh just five grams, cost only $25 to produce, and seem fully equipped for permanent orbit. Each of these tiny satellites contains a microprocessor, two aerials, a solar cell, a magnetometer (to measure both the strength and the direction of a magnetic field in space), a gyroscope (for direction), and a radio strong enough to send a signal back to Earth.
SpaceX itself did not create these nano satellites. Zac Manchester of Cornell University is the man behind their creation and development, which was funded by a campaign on Kickstarter, a crowd funding website.
With video confirmation that SpaceX successfully pulled off the nearly impossible Falcon 9 landing (link below), the sky is obviously not the limit for the private rocket firm headed by Elon Musk. SpaceX also has a 1.6 billion dollar contract with NASA to launch unmanned Dragon cargo ships to the International Space Station.
