The Open Source Satellite Programme vision is to make space more accessible through collaborative design and manufacture of a fully open source micro-satellite. Sign up at www.opensourcesatellite.org to participate and to get access to unique content. Working with the community, our aim is to develop a low-cost, high performance platform on which versatile missions, space-based applications and services can be developed and implemented. Our goal is to stimulate the responsible and sustainable, exploitation and utilisation of space, share knowledge, create excitement and make a difference.
