This Space Available, by Emily Carney. In last week’s This Space Available post, we introduced Dr. Gerard K. O’Neill, a Princeton physicist, who, at mid-career, was struggling to bring his ideas about space settlement to a wider audience. We left with him finally publishing his iconic article “The Colonization of Space” in the September 1974 issue of Physics Today, developing a larger base of followers with the establishment of the L5 Society, and becoming one of sci comm’s first superstars. While we will catch up again with O’Neill in future posts in this series, this week we will revisit Dr. Brian O’Leary following 1972, the year he introduced his friend O’Neill to a large, enthusiastic audience at Hampshire College – an event which would forever impact space history.

This Space Available, by Emily Carney. This weekend, many of us on the United States’ eastern coast made preparations for Hurricane Dorian, the devastating tropical cyclone that has been parked over the Bahamas for close to an entire day. While Dorian’s slow speed and reluctance to turn away from Florida’s east coast have been the butt of many memes and Facebook jibes, current meteorological satellites such as GOES-16, along with ground-based radar, have provided incredible, often stunning visual data related to the historic storm.
