Blue Origin's future goal is to get their next rocket, named New Glenn, after another astronaut, into orbit.

And as for the project after that, well, the name is New Armstrong.

it is clear that Blue Origin intends to make its way to the moon.

This is in line with Bezos' stated objectives, to pave the way for industry to more accessibly get into space.

Although he doesn't expect to see it in his lifetime, Bezos has said that he expects much of the Earth's heavy industry to one day be done in space.

Our last billionaire, however, has his eyes on an even further goal.

Elon Musk's company, SpaceX, is a little different from the other two.

While Virgin Galactic and Blue Origin focus on space tourism, SpaceX has been more focused on commercial ventures.

Since its founding in 2002, SpaceX has grown to dominate the market, taking half of the contracts to launch satellites into space.

Part of its success in this area is due to the fact that its rocket, the Falcon 9, is reusable.

This reusability drastically reduces the cost of launches, making launching satellites and other cargo much cheaper.

The Falcon 9 is much larger than New Shepard or Spaceship Two.

While the latter two are roughly comparable, at 18m in length each, Falcon 9 is 70m.

Its thrusters are powerful enough to get it into orbit.

It carries a reusable cargo capsule named the Dragon, the first of which carried supplies up to the International Space Station.

The Falcon 9 is able to carry 5,500 kg of weight into orbit, or more if they are willing to sacrifice the reusability of the rocket.

This ability to transport cargo reflects a possible future purpose of SpaceX, to carry freight to Mars.

Elon Musk has always made it clear that he intends to one day see a colony on Mars, and in 2001, his company conceptualised greenhouses that might grow plants there.

Any such colony will no doubt need supplies from Earth, particularly in its early days, as vital equipment and personnel would need to be transported over.

Any company with the large-scale capability to transport heavyweights between Earth and Mars would stand to make a lot of money.
