And they have had neither the priority nor the will to achieve it - they don't use even 2% of their budgets (of $25 billion per year) to study the design of launch vehicles suitable for passenger service! ![]() The only reason why this hasn't been done yet is that launch vehicle development has been left to government space agencies. But there's no technical reason why reusable launch vehicles couldn't come to be operated routinely, just like aircraft. Launch to orbit requires accelerating to Mach 26, and so it uses a lot of propellant - about 10 tons per passenger. You could be forgiven for thinking that space is therefore an impossibly expensive place to get to. Only the Space Shuttle survives past one use, and that's only if you ignore the various parts that fall off (intentionally!) on the way up. But in order for these to start we need vehicles that will take us to orbit and bring us back.Ĭurrent space vehicles clearly cannot. For many many people space tourism and even colonisation are attractive ideas.
