Not for space sharks, it was in their kits in case a reentry capsule missed its designated splashdown zone. The shark repellant contained copper acetate, which apparently smelled like a dead shark when sprinkled into the water. This shark chaser is in the collection of our @airandspacemuseum. Swipe to see a @NASA image of a Marine helicopter picking up Mercury astronaut Alan Shepard and his Freedom 7 capsule in the Atlantic Ocean after his first American sub-orbital flight on May 5, 1961. Luckily, shark attacks are rare. Humans need sharks to keep ocean food chains healthy and maintain ecosystems such as coral reefs. #SharkWeek #OurSustainablePlanet 🎥 Image 1: Small yellow satchel tied with yellow string labeled Shark Chaser. A paper tag includes handwritten text NASM, object number, and Shark Chaser from Freedom 7. Image 2: On a sunny day, a helicopter hovers close over a calm sea, its blades causing radiating white waves. Below it, a space capsule on a rope with a person dangling on it.」7月12日 21時13分
