A quick guide to everything SpaceX

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.

Elon Musk founded SpaceX after being unable to purchase affordable rockets abroad

Overcoming industry skeptics, SpaceX provides low-cost, high-publicity spaceflights

From recovering and reusing rocket components to launching a mannequin and Tesla into orbit to the tune of David Bowie's "Starman," Elon Musk drove public interest and government contracts to his company as he transformed space launches into spectacles.

SpaceX's S-1 or 'prospectus' revealed many previously unknown details about the company

Those revelations include the company's unprofitability despite doing $18.7B in revenue in 2025, exactly how many voting shares Elon Musk will have in the company (roughly 85%), and more.

How SpaceX Made Space Affordable

SpaceX has cut launch costs by over 95%—from $54,000 per kilogram to around $2,000—reshaping how we access space.

SpaceX has established an efficient schedule for launches of ISS crew shuttles and Starlink satellites, with blastoffs occurring just under once every four days in 2023—a pace that has since accelerated as the company has won more contracts.

NASA and SpaceX combine public support and funding with private enterprise

Rather than competitors, SpaceX and NASA are mutually beneficial collaborators. Without NASA contracts, SpaceX may have run out of funding, and without the low-cost tech of SpaceX, NASA may have been left without a US-based launch system.

The first version, called Starhopper, was named with the vision of developing rocket stages that could safely land after use, enabling reusability to cut costs. The endeavor was an enormous engineering challenge that required years of testing.

SpaceX has launched thousands of its Starlink satellites into low-Earth orbit

Every launched batch of satellites contains roughly 60 of the desk-sized gadgets. The batch is released at random into an initial orbit, and it takes time for them to naturally spread out enough before operators begin unfolding their antennae.

Billionaires are racing to space to control future markets

Although different companies have described focuses ranging from luxury tourism to Martian space colonies, all are building infrastructure to capitalize on the shift away from government-only control and betting big on reusability and scale. By securing public contracts and subsidies, they aim to develop strategic partnerships toward dominance in low Earth orbit.

SPACs, explained

Special purpose acquisition companies make it easy for mature unicorns (companies valued at over $1B) to receive growth capital by going public. This process effectively skips the work of a traditional initial public offering, and its time-intensive investor negotiations. Typically, a well-known investor with expertise in a certain industry sponsors a SPAC with the intent to acquire a startup. Learn how it works and the risks involved here.

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.

SpaceShipOne was the first privately built spacecraft to reach the boundary of space

The rocket-powered aircraft was built by Richard Branson's company Virgin Galactic. The English business magnate has described being inspired to go to space since he was a child watching NASA's moon landings.

Blue Origin, Jeff Bezos’ aerospace company, sent its first passengers to space in 2021

Founded in 2000, Bezos spent many years working on the company as a side project before it became more well-known around 2004, when a plot of land in Texas was purchased as a launch site for the company’s rockets. He has said that the goal of Blue Origin is to build “reusable space vehicles.” This resource details what passengers experience from takeoff to landing on a Blue Origin flight.

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.
