About Axelspace

Axelspace has been one of the pioneers of micro-satellite technology and industry since the establishment of the company in 2008, and we envision to democratize the space technology to a wider population across the globe for their daily use. A new project started in 2015 called AxelGlobe which aims to provide a new Earth observation infrastructure by launching multiple micro-satellites for its higher data frequency. We have successfully launched our first satellite in 2018 and then four more satellites in March 2021. As we prepare for the upcoming launches for more satellites in the near future, we currently face a pivotal stage in the development for democratizing satellite imagery use to the world. If you find yourself getting excited working to making a global difference with the use of micro-satellite technology, hit that "apply" button! We look forward to making our vision "Space within you reach" come true together!
