A Guide to CubeSat Mission and Bus Design
Cool new CubeSat guide drops, but readers say it feels a bit too USA-only
TLDR: An open, beginner-friendly CubeSat guide just landed, but the headline reaction is a call for a less U.S.-focused perspective. Readers want global case studies and rules, arguing that a worldwide field needs a worldwide guide—turning Edition 1 into a community wishlist for a more inclusive Edition 2.
A shiny new open textbook just launched: Frances Zhu’s A Guide to CubeSat Mission and Bus Design, packed with step‑by‑step planning, labs, and plain‑English walk‑throughs for tiny satellites. But the real blastoff happened in the comments, where the top vibe was: great resource, too American. One early voice called it “US‑centric,” and the sentiment spread—global readers want the book to orbit beyond NASA examples and U.S. university playbooks. They’re asking for case studies from Europe, Asia, Africa, and Latin America, plus notes on different regulations, launch providers, and success stories outside the States. Defenders countered that it’s Edition 1 from a U.S. program and an open book means the community can help expand it—“submit chapters, don’t just roast.” That only fueled the takeoff: critics say “open” should mean open perspectives now, not later. The humor brigade showed up with memes like “US‑atellites” and quips that “orbits don’t need passports,” while a few pleaded to keep the focus on fundamentals, not flag counts. Either way, the thread turned into a global wish list for Edition 2. The consensus? The book is a strong launch—now give it international thrust. Dive into the text here: Preface
