Rockets are HUGE, complicated and expensive. As a matter of fact, the rocket that took humans to the moon, the Saturn 5, was 111 meters or 363 feet tall, and had more separation events than dating teenagers.

So why do rockets always split themselves into multiple parts. Isn’t that complicated and risky? Why throw so much away? I mean, there’s got to be a better way!!!

Well how about if rockets were only ONE stage? How awesome would that be? Well this idea isn’t new… it’s called single stage to orbit or SSTO and it’s often considered the holy grail of rocketry.

Well, today, I’m going to SMASH THAT HOLY GRAIL and explain why I think SSTO’s SUCK.

In order to drill this point in we’ll teach you all about the tyranny of the rocket equation and help you understand why every orbital rocket, well, ever is multistage.

Then we’ll take a stroll down SSTO history and look at some crazy designs that in some cases almost worked...

And not to be a huge downer, we will take a look at some SSTO designs that MIGHT actually work, including the Skylon spaceplane that uses the awesome SABRE hybrid engine.
