On 19 August 1960, two Soviet street dogs named Belka and Strelka became the first living creatures to orbit the Earth and return home alive aboard Sputnik 5. Their survival proved the concept of safe re-entry and made human spaceflight possible. Clara Vale also explores Robert Holmes’s spectacularly destructive naval raid on the Dutch merchant fleet in 1666, the teenage Octavian’s armed negotiation with the Roman Senate in 43 BC, and the 2017 collapse of a salmon pen in Washington State that released hundreds of thousands of non-native Atlantic salmon into Pacific waters. A compact history of audacity, ambition, and things that really should not have worked but somehow did.
