Konstantin Kakaes announces a new book about the Pioneer Anomaly and the investigation into its cause:

The Pioneer Detectives

I’ve just published a short book. I’m very excited about it, and wanted to share the news with you.

The Pioneer Detectives is on sale now on amazon.com for a mere $2.99, less than a cup of fancy coffee. It’s also out in Britain for just £2 (and a half-shilling).

The book is short and fun—the length of a novella—but also, in the words of Amazon’s reviewer, “powerful and sad”. If you’ve got any curiosity about how NASA works behind the scenes or why scientists believe what they do, I think you’ll enjoy the book. Many others already are—I’m happy to say it’s the #1 best-selling Kindle Single in “The Sciences” and the #2 best-selling astronomy book on Amazon.

The book tells the story of the “Pioneer Anomaly”—a force slowing down the spacecraft Pioneer 10 and Pioneer 11 while they left the solar system as humanity’s first emissaries into the galaxy. I hope you’ll forgive the mass e-mail, both if it’s been quite a while since we’ve talked, and if we’ve been in touch recently and you’re already aware of the book.
