Founded by entrepreneur Elon Musk in 2002, SpaceX did not have an easy start - it was bordering on bankruptcy in 2008 after three failed launches.
Today the aerospace company has about $10 billion worth of launches booked, built the world's most powerful operational rocket, and touts an ambitious goal to colonize Mars.
Its success has so far relied on its workhorse launcher: the 229-foot-tall Falcon 9 rocket. But continued industry dominance is anything but guaranteed.
In the near future, Musk and SpaceX will face competition from a number of companies, including Jeff Bezos' Blue Origin, that are developing reusable, next-generation rocket engines and boosters.
Here's how the competition in the new space race stacks up.
