SpaceX is all about reducing the cost of launching things into space, and right now one of those costs it think it can eliminate is having to use a new fairing every time it launches a rocket. The fairing is basically the shell at the top of the rocket that protects whatever cargo’s being launched (for instance, it housed the Tesla Roadster and SpaceX’s Starman mannequin during the recent Falcon Heavy test launch).

The fairing costs $6 million to produce, and so re-using it for multiple costs could lead to a significantly reduction in how much each launch individually costs SpaceX. SpaceX recovered a nose cone last year during a launch, but it has a new plan for fairing retrieval that should make it more repeatable and reliable to get these things back.
