Shortly after the main section of SpaceX’s first recycled Falcon 9 booster landed itself on a platform in the ocean, half of the rocket’s nosecone, which protected a communications satellite during launch, splashed down via parachute nearby.
Measuring 13 metres long and 5 metres in diameter, the nosecone is big enough to hold a school bus. It separates into two pieces, exposing the satellite, about 4 minutes after liftoff. As a test, SpaceX outfitted the fairing with thrusters and a steerable parachute.
After some debate about whether the nosecone could be recovered, Musk said he told his engineering team, “Imagine you had $6 million in cash on a pallet flying through the air that’s just going to smash into the ocean. Would you try to recover that? Yes, you would.”
