Ill-Defined Space provides analysis of activities, policies, and businesses in the space sector. The purpose of these analyses is to bring some definition and clarity for a sector with many stakeholders, missions, and businesses.



Ill-Defined Space is written by me, John Holst.

My analysis of the space industry has been a definitive source for national lawmakers and departments, news outlets such as Bloomberg and the San Francisco Chronicle, publications like National Geographic, and National Public Radio.

My research and analysis of the global space industry have been published in The Space Report: The Authoritative Guide to Global Space Activity from 2014-2019 (here’s a link to a 1Q19 promo copy). You can also see my work in Quilty Analytic’s series of LEO Broadband Reports.

I’ve worked in the United States Air Force, Missile Defense Agency, Cobham, Space Dynamics Laboratory, the Space Foundation, and Quilty Analytics. I focused on space operations in the first few and conducted space industry research and analysis with the last two.

I was an undergrad at the University of Washington in Seattle and graduated with a degree in Journalism.

Why Stamps?

The space-themed stamps show just how interested many nations are in any space achievement–no matter which nation did the deed. Plus, many are beautiful works of art, so it seemed wasteful to not post them for others to enjoy.
