OSSHW Organizations

At Mach 30, we dream of a world where people live and work on other worlds and in space stations.  When we say people, we don’t mean six at a time, we mean hundreds, then thousands, then tens of thousands. One of the keys to making this dream a reality is to share the technology of space as widely as possible, and so we are doing all of our engineering work as open source hardware, and we are not alone.  In the last four years nearly one dozen groups have formed with the stated purpose of developing Open Source Spaceflight Hardware (OSSHW). These groups intend to develop and then share the designs of a wide variety of space systems including launch vehicles, satellites, and lunar probes.  If we are missing anyone, please let us know.

Copenhagen Suborbitals

Copenhagen Suborbitals is an all volunteer Danish organization founded by Kristian von Bengtson and Peter Madsen. The mission of Copenhagen Suborbitals is to launch a human being into space. They are currently developing a sub-orbital spacecraft composed of a one-person capsule called the Tycho Brahe, and a booster called HEAT.  Documentation of their work can be found on their Resources/Downloads page.

The Collaborative Space Travel and Research Team

The Collaborative Space Travel and Research Team (CSTART) is an all volunteer organization with members throughout the world. CSTART was founded in 2009 by a group of space enthusiasts who met in an online community site called Reddit. The mission of CSTART is to organize and finance open source spaceflight projects run by space enthusiasts. Current CSTART projects include a cubesat called COSMoS, a high altitude balloon called Cloudlab, and a hybrid rocket called Chimera.  Update May 2013 – CSTART’s forums have been dark for some time now, but we are leaving CSTART in this list because of the great work that can still be found in their forums and wiki.  Update October 2013 – CSTART’s homepage is dark, the website redirects to a 403 error.  If this is still the case in January 2014 we will remove them from the list.

Develop Space

Develop Space is a 501c3 non-profit organization founded in 2007. Its mission is to enable human exploration and development of space through open collaboration. Develop Space projects include an architecture study for a minimalist human mission to Mars, the development of a space exploration reference library, and research into engineering tools that are licensed as open source software.

Mach 30

Mach 30 is a non-profit organization incorporated in 2009. Our mission is to hasten the advancement of humanity into a spacefaring society. Current projects at Mach 30 focus on developing a strong legal and organizational foundation for running open source spaceflight projects. These projects include the Openeering Wiki, a community portal documenting the existence of and experience using free and open source engineering tools, Open Design Engine, a web based engineering project management portal, and research into licensing and management of open projects within the boundaries of export control laws such as ITAR.

Open Aerospace

Open Aerospace was founded by Ralph Ewig in 2009. The mission of Open Aerospace is to be the organizing framework for space enthusiasts to collaborate on human activities beyond Earth. Open Aerospace’s projects focus on defining an end to end architecture for space exploration.

OpenLuna Foundation

The OpenLuna Foundation is a 501c3 non-profit organization founded by Paul Graham and Gary Snyder. The mission of Open Luna is to return humans back to the moon through private enterprise. Early projects at Open Luna are focusing on a series of robotic missions and public outreach. Their eventual goal is to build a small human outpost on the moon.


From their website – “Opennautics is dedicated to exploration with Open Source Hardware. We are a community that creates and shares ideas and designs around amateur rocketry and astronomy. We build tools to aid in space exploration.  Members from all over the world are encouraged to participate. In addition, members of all different educational backgrounds are encouraged to join. Anyone with a passion can contribute.

Open Source Starship Alliance

The Open Source Starship Alliance is a Facebook community centered around activities and participation in the 100 Year Starship Symposium and the work that came from the symposium.  Conference attendees, participants who submitted proposals for the 100 Year Starship program, and anyone interested in open source starship technology are encouraged to join.

Portland State Aerospace Society

The Portland State Aerospace Society (PSAS) is a student organization at Portland State University. PSAS projects center around the development and operation of low cost open source rockets. Their most recent launch, held in October of 2010, was a complete success.


SpaceGAMBIT is an international group of space enthusiasts working at makerspaces around the world to develop open source spaceflight hardware.  SpaceGAMBIT was launched by a $250,000 grant from DARPA in the fall of 2012.  Current plans call for using the grant money to fund open source spaceflight projects at makerspaces.


Team FREDNET is an official competitor in the Google Lunar X-Prize. Team FREDNET is incorporated as a 501c3 non-profit organization. As a competitor in the Google Lunar X-Prize, Team FREDNETs projects all center around the development of a prize winning lunar rover.

Ultra Light Space Flight

The Ultra Light Space Flight (ULSF) group is a community of individuals who are working on developing open source space probes.  Their core value is to “to the smallest possible craft operating on the smallest possible budgets” and they believe that robotic probes have been and will continue to be the backbone of space exploration.


WikiSat is an international group of volunteers and students. Their mission is to make access to space open to everyone. Their current projects include a high altitude balloon that will act as a proof of concept for their engineering processes, and a ultra-small scale satellite launcher as an entry to the N-Prize.  Update October 2013 – The website appears to be down (possibly no longer being maintained), linking to Wayback Machine copy for now.
