Smallest Satellite Ever Sent & Operated in Orbit By Breakthrough Starshot

Breakthrough Starshot is a research and engineering project by Breakthrough Initiatives to develop a proof-of-concept fleet of light sail spacecraft, named StarChip, capable of making the journey to the Alpha Centauri star system, 4.37 light-years away, at speeds between 15% and 20% of the speed of light, taking between 30 and 20 years to get there, respectively, and about 4 years to notify Earth of a successful arrival.

The project was announced on 12 April 2016 in an event in New York City by physicist and venture capitalist Yuri Milner and cosmologist Stephen Hawking who is serving as board member of the initiatives. Other board members include Facebook CEO Mark Zuckerberg. The project has an initial funding of US$100 million to start research. Milner places the final mission cost at $5–10 billion, and estimates the first craft could launch around 2036.

It is now in orbit!

On June 23, the initiative sent the tiniest-ever satellites into orbit. Thanks to an Indian rocket, 6 of these satellites, as named as Sprites, went to space. Some of them were attached to larger satellites: : the Latvian Venta satellite and the Italian Max Valier satellite which will release the other four Sprites to orbit once communications are achieved.

In fact, each Sprite contains a computer processor, solar panels, a magnetometer, a gyroscope, and a radio for communicating with researchers on Earth and all in a size of  3.5×3.5 cm circuit board.
Until now, only one signal came from on of the 2 Sprites. Since the Max Valier hasn’t established a connection yet, the remaining Sprites didn’t detach. Usually the satellite should receive a command to release its cargo, and this is not possible without a functioning antenna.
Despite the humble results, the team is feeling victorious. Having these small and cheap satellites hovering over the space and doing part of the job is an achievement.
These tiny satellites can go along on a planetary exploration mission and start deployment once they get there. By using these satellites, the risk of sending large spacecrafts will diminish.
