&quot;New-space&quot; aerospace companies are operating on a different funding framework from the old aerospace juggernauts. Instead of cost-plus funding that came almost solely from the government and which allowed rockets like ULA&#x27;s Delta IV and Atlas V to stay competitive in the $300-400 million range without having to find ways to cut costs. SpaceX, Blue Origin, and Orbital Sciences, as well as other new companies, have to innovate in order to make their businesses feasible.<p>Additionally, Blue Origin and SpaceX have different goals from traditional aerospace firms that requires them to drive costs down below what a government would require. Blue Origin want to offer rides to space to tourists; for that, their costs need to be low enough for a person to buy a ticket. SpaceX wants to land their rockets on Mars, and then take off again. Being able to land the first stage of the Falcon 9 allows them to perfect the landing and reuse of rockets on Earth, before taking that knowledge to Mars.
