Bruce Mackenzie advocates low tech “homesteading” to live on Mars. He originated the concept of Masonry structures on Mars, using regolith (dirt) to hold the internal pressure.
Bruce has been active in the National Space Society since the merger with the L5 Society.
He served multiple terms on the NSS Board of Directors, chapters committee, local chapter, multiple chapters web support, and other duties.

Bruce is the founder of the Mars Foundation, an NSS affiliated organization, dedicated to
education and research on settlement of Mars. His special interest is the use of in-situ materials, such as production of plastic and masonry from the Martian air and dirt, to build habitats and 3D printing for Mars Settlement.

​

Other activities include:
Mars Society advisory Steering Committee, AIAA local council,
Space Studies Institute, SEDS, Mars University,
entrepreneurial ventures, software engineering, aerospace engineering, cad
development, gps receivers, and, would you believe gun launched satellites.
But, the most fun were:
Mars Settlement designs, space elevators, and the use of rotating space
tethers to establish industry on Luna and export Lunar materials,
and intergalactic settlement.

Bruce lives near Boston, USA, with his spouse and 2 grown children.
