von Braun's law

Von Braun's Law relates to space launch costs, stating that each dollar spent on developing reusable rocket technology, like those used by SpaceX, effectively reduces the cost of each space launch by about a dollar. In other words, investing in reusability creates a direct, proportional decrease in launch expenses because reusable rockets can be launched multiple times, spreading out development costs and eliminating the need to build entirely new rockets for each mission. This principle underscores the importance of reusable technology in making space travel more economical and sustainable.
