SkyCube: The First Satellite Launched by You!

Southern Stars has built a nano-satellite called SkyCube that launched into orbit on 9 January 2014. SkyCube was financed by thousands of sponsors and mobile app users around the world. It was a global grass-roots public outreach and educational effort to make space exploration accessible as never before.

SkyCube launched from the Mid-Atlantic Regional Spaceport on the Antares/Cygnus Orb-1 mission to the International Space Station on January 9th, 2014 at 1:07 PM Eastern Standard Time.

SkyCube was deployed from the ISS into its own orbit on 28 February 2014. The first signals from SkyCube were receieved on 27 March 2014. SkyCube re-entered the Earth's atmosphere on 9 November 2014 before becoming completely operational. The satellite's purpose was to send simple broadcasts - "tweets from space" - for amateur radio operators around the world to hear, and to transmit low-resolution Earth images. Finally, at the end of its 90-day mission, SkyCube was programmed to inflate an onboard balloon, to make SkyCube visible to the unaided eye, and to de-orbit cleanly through atmospheric drag.

Sponsorship and Rewards

SkyCube began life as a successful crowd-funding campaign on For the latest news on SkyCube, check out the project's update page.

Although we are a for-profit company, SkyCube is not really about profit. It's about changing space exploration from something reserved for governments, corporations, and billionaires into an arena that is affordable and accessible by everyone. It's about inspiring a new generation to take risks and accept challenges. It's about acting collectively, sharing risks and expenses, to achieve something together that none of us could have accomplished alone. It's not (just) a science project - it's a social project.

Southern Stars has developed Satellite Safari, an iOS and Android app for tracking SkyCube and other satellites.
SkyCube will become visible at the end of its mission by inflating a large on-board balloon.

We would like to thank MacTech magazine, SkyCube's first corporate sponsor, for its $25,000 award to the project in 2012. Additional corporate sponsorhip opportunities for SkyCube are still available; for more information, please contact us by email to, or on any of the phone numbers at the bottom of this page.
