Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics is my guest on the Cold Star Project, and our space topics are many. Main-belt asteroid 4589 McDowell was named after him in 1993, and he was a contributor to Sky and Telescope magazine from 1993 - 2010. Since 1989 he has authored and edited Jonathan's Space Report, which tracks all known space launches.  

We discuss:  

the Chandra spacecraft x-ray telescope, which recently hit the 20-year-old mark
what Dr. McDowell has discovered about dark matter and quasars
whether or not he believes the ISS can be considered practical for commercial ventures
how much time and attention Jonathan's Space Report (JSR) takes, and what opportunities have arisen for him because of the consistent effort maintaining it
how good or poor registering and tracking of space objects really is, and whether we are truly ready for megaconstellations.
