Episode 13 --- Why Future Space-Based Arrays Of Optical Telescopes Will Likely Be 3-D Printed In Orbit

Lowell Observatory astronomer Gerard van Belle, Chief Scientist at the Navy Precision Optical Interferometer (NPOI) in Flagstaff. Arizona talks about the possibility of arrays of space telescopes that are 3-D printed after launch.  We also discuss the history of optical interferometry; why such interlinked telescopes are the key to America’s future in astronomy and why Arizona skies remain as vital today as they were a century ago.
