Asteroid mining, orbital 3-D printing, and--of course--manned spaceflight are all part of the modern-day space race.
For making rockets reusable, and Mars seem possible. Already the world's most high-profile commercial spaceflight company, SpaceX continues to demonstrate its technical bona fides, racking up recent milestones as historic as they are diverse. Along with fielding a more muscular version of the workhorse Falcon 9 rocket (with engines that are 50% more powerful than their predecessors), the company conducted a series of test flights of its Grasshopper rocket, which traveled as high as 1,066 feet in June 2013 before depositing itself back on the launchpad, as opposed to dumping in the ocean. SpaceX flies fast, cheap, and always in control, making founder and CEO Elon Musk's plan to eventually establish a permanent, 80,000-person Martian colony, seem less like a pipe dream, and more like the inevitable.
