We build rockets. They get sent up. Crash into the ocean. At fabrication where it’ll be reclaimed and used for another rocket. Months pass by and this process will occur again and again as it has for the same amount of time as NASA has. We waste metal and other valuable resources by letting multi stage rockets land in the ocean to be reused later. One major leader in the space industry in Elon Musk and he plans on changing this. With SpaceX he has achieved landing a Stage 1 rocket, ultimately he plans on decreasing the time to recover and repair stages of a rocket and to be able to land all stages of a rocket. It’s important because these reusable rockets are the necessary steps to travelling to space.
