Say hello to FemtoSats — the tiny new satellites that could democratize space

The FemtoSat, also known as SunCubes, were developed by Professor Jekan Thangavelautham from the Arizona’s School of Earth and Space Exploration. The cubes are amazingly small and light, measuring a mere 3cm and weighing only 35g. These FemtoSats are significantly smaller than their CubeSat counterparts, which are 11cm long and 1.3kg in weight.

The FemtoSats are not only small and easy to deploy, they are also affordable when compared to the CubeSat, which costs up to $50,000 to prepare for launch and $100,000 to launch into orbit. According to the Arizona State team, each FemtoSat will cost $3,000 to deliver into a lower Earth orbit, and, if desired, $1,000 to send to the International Space Station.

The FemtoSat will be deployed using a CubeSat equipped with a spring that will shoot the FemtoSat out into space. Approximately 27 FemtoSats can be released by a single deployer. This will cut down on launch costs, allowing the FemtoSats to piggyback on existing CubeSat missions.

The Arizona researchers hope their FemtoSats will make it possible for the hobbyists, students, and other enthusiasts to explore space. “By reducing the launch cost, it is hoped a wider community of educators, researchers, and hobbyists can develop their own spacecraft,” said the team. “The standard is targeted towards personal, scientific, private, and government payloads.”
