This website provides an overview of the current state of the art of small spacecraft technology. It was first commissioned by NASA’s Small Spacecraft Technology Program (SSTP) in mid-2013 in response to the rapid growth in interest in using small spacecraft for many types of missions in Earth orbit and beyond, and further revised in mid-2015. In 2016 the decision was taken to migrate from a written report to an online website.
