SpaceX was built to achieve Elon Musk's vision of making humans an interplanetary species.

A primer on SpaceX's primary rockets and spacecraft

SpaceX has developed several lines of rockets, from its workhorse Falcon 9 to the visionary Super Heavy rocket of the company's Starship designed for massive payloads. Each iteration costs millions of dollars and came with scientific and economic challenges and several are no longer in development. Learn more about the company's roster of rockets and craft here.

A quick guide to everything SpaceX

SpaceX has single-handedly reignited commercial space exploration, with its reusable rockets, broadband satellite constellation, and plans to populate Mars. The company has gone from a mere idea in 2002 to the world's most well-known private space company. Learn the basics about this pivotal company with this quick guide from CNET.

How reusable rocket boosters work

Reusable rockets drastically reduce the costs of space travel, saving agencies and companies millions of dollars by preserving expensive, complex boosters and their engines. The advancement required engineers to develop systems that restarted a booster in mid-flight to slow it down before landing.

The reusability of Falcon 9's first stage rocket has slashed launch costs

Unlike older rockets left to sink in the ocean, the first stage was designed to steer itself back for a controlled landing on a sea-based barge. Refurbishment of these components are half the cost of building new.

SpaceX hopes to use the vehicle for both interplanetary travel and shorter flights around Earth. At 30 feet wide, it allows for more storage and headspace for inhabitants than previous NASA spacecraft.

See the unbuilt rocket design that would have dwarfed the Saturn V

Designed in the early 1960s, the Sea Dragon was a radical concept for an ocean-launched rocket that would have far exceeded the Saturn V in size and payload. The conceptual design was ultimately too risky and impractical to build.

Falcon 9's first stage is able to land within a 30-foot diameter target consistently

SpaceX's Falcon 9 rocket releases its reusable first stage hundreds of miles above the Earth's surface as it travels thousands of mile per hour. The stage often then lands on an autonomous ocean drone in the middle of the sea.

Microgravity environments improve the success of 3D bioprinting

Gravity can cause gaps, such as those in the chambers of a 3D-printed heart, to collapse before stem cells, hydrogels, and biochemicals bind together during the bioprinting process. Rather than Earth's surface, some bioprinting is done on the International Space Station, where defective organs are also printed to test treatment methods.
