Welcome to the new online home of the NASA State of the Art Report of Small Spacecraft Technology.
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.
For the sake of this assessment, small spacecraft are defined to be spacecraft with a mass less than 180 kg. This report provides a summary of the state of the art for each of the following small spacecraft technology domains: Complete Spacecraft, Power, Propulsion, Guidance Navigation and Control, Structures, Materials and Mechanisms, Thermal Control, Command and Data Handling, Communications, Integration, Launch and Deployment, Ground Data Systems and Operations, and Passive Deorbit Devices. Due to the high market penetration of cubesats, particular emphasis is placed on the state of the art of cubesat-related technology.
