Three More Cover Features

Three issues of How It Works magazine

In a previous post, I mentioned that I had three consecutive cover features in How It Works magazine between November 2021 and January 2022. I’ve just come close to repeating that feat, making the cover for three out of the four issues between June and September this year. As pictured above, the topics this time were near-Earth asteroids, gravity and the solar cycle. The first two are particular favourites of mine, having previously covered the asteroid threat in my book Cosmic Impact, while my PhD thesis was all about gravity and its effects on stellar orbits. Around 15 years after that, in the late 1990s, I had some peripheral involvement with BAE Systems’ “Project Greenglow” on the possibility of gravity control (or antigravity, if you like) – something I’ve written about on a number of occasions, for example in this blog post from 2015. As I said there, my link to the BAE project came through its leader, Ron Evans, who I’ve remained in touch with ever since. So I was really pleased when the magazine editor asked me to include something about “antigravity” in the How It Works feature, as it gave me the opportunity to include a brief Q&A with Ron as a sidebar at the end of the article.
