This Week in Space 228: What's a HOTOL?

All TWiT.tv Shows (Audio)

About

In the 1980s, as the US space shuttle was just starting operations, the UK embarked on an ambitious project called HOTOL—short for Horizontal Take Off and Landing, a radical, air-breathing spaceplane design. Political and funding shifts in the UK ultimately derailed the project, despite the promising technologies it pioneered. The idea was later restarted as Skylon, with key individuals and refined technologies at its core. This project, too, struggled, ultimately shuttering in 2024. Despite this, the promise of rapid, reusable spaceplanes that can launch and land at airports is still coveted by many countries, and efforts continue. Join Rob Coppinger, author of the definitive book on the topic and editor of the UK's "Spaceflight" magazine, as he tells this fascinating story.
