Imagine if after every flight in an airplane you had to destroy the thing and build a new one from scratch. Sounds ridiculous, right?

It is hard to understate how much of an achievement reusability represents in terms of the future cost of spaceflight. With SpaceX looking to get turnaround times down to under 24 hours with little to no maintenance cost, soon the most expensive part of the launch will be the fuel, and launches could drop to as little as one tenth of their current cost.

And with the cost of launches dropping, it becomes more financially viable to launch a larger volume of smaller, less costly payloads, making spaceflight more accessible for smaller organisations and potentially even private individuals.
