About

Howard A. MacEwen is a visionary in the field of space astrophysics, focusing on the intersection of human spaceflight and next-generation observatory design. His primary research areas include in-space servicing, assembly, and infrastructure for large telescopes, with a particular emphasis on overcoming the physical limitations of launch vehicle fairings. MacEwen’s major contributions center on the concept of the Modular Assembled Space Telescope (MAST), a proposed 20-meter UV-optical observatory that would be assembled in orbit rather than deployed autonomously. This work, detailed in his 2013 paper (5 citations), challenges conventional thinking by advocating for human-assisted construction to enable telescopes far larger than current rockets can accommodate. His 2017 paper on human space flight and future flagship missions (9 citations) further explores how servicing and assembly could unlock the potential of “flagship” observatories that approach payload limits. Though his citation counts are modest, MacEwen’s forward-looking ideas have influenced discussions on cost-effective, scalable space architectures. By championing modularity and in-space infrastructure, he has provided a roadmap for future missions that may one day revolutionize our view of the cosmos.
