SpaceX was born from a single question: why does a rocket cost $65M when its raw materials cost $200K? In 2002 Musk drove to NASA, asked to buy a surplus rocket, and was laughed out of the building. He went home and built one. Today SpaceX launches more mass to orbit every year than all other launch providers on Earth combined, recovers its boosters from the sky like science fiction, and is the only company in history to have flown humans to the International Space Station under a commercial contract.
Founding Story
SpaceX originated in a single frustrating trip to Moscow in 2001. Musk had gone to buy a surplus Russian ICBM for a Mars Oasis PR project. The Russians laughed at him and doubled their price to $21 million. On the flight home, Musk opened a spreadsheet and calculated the actual materials cost of a rocket. The gap between materials cost and market price was absurd. A new company was the only logical conclusion.
Space Exploration Technologies Corp. was incorporated on March 14, 2002, with $100 million of Musk's personal PayPal proceeds. Falcon 1, a small two-stage rocket, was the first test vehicle. It failed on its first three attempts. By the third failure in August 2008, SpaceX had enough money for exactly one more launch. The fourth attempt, on September 28, 2008, reached orbit.
Three months later, NASA awarded SpaceX a $1.6 billion commercial resupply contract — arriving days before SpaceX would have run out of money entirely. Falcon 9 followed in 2010. The December 2015 vertical landing of Falcon 9's first stage proved that reusable orbital rocketry was not science fiction.
Crew Dragon carried NASA astronauts to the International Space Station in May 2020, restoring American human launch capability for the first time since the Shuttle's retirement in 2011. Starship — the Mars vehicle — has been under iterative orbital testing since 2023, with the Mechazilla booster catch of IFT-5 in October 2024 the most dramatic single milestone in spaceflight history.

Overview
Space Exploration Technologies Corp. was founded by Elon Musk in March 2002 with $100M of his PayPal proceeds. Stated goal from day one: make humanity multi-planetary. Falcon 1 reached orbit on its fourth attempt in September 2008 — the first privately-funded liquid-fueled rocket to do so. Falcon 9 first launched in 2010, recovered its first booster in December 2015, and re-flew one for the first time in March 2017. Crew Dragon carried NASA astronauts to the ISS in May 2020 — the first crewed orbital launch from US soil since the Space Shuttle's retirement in 2011. SpaceX operates Starlink, the largest satellite constellation ever built. Starship — the Mars vehicle — has been undergoing iterative orbital tests since 2023. On February 2, 2026, SpaceX acquired xAI in an all-stock transaction, bringing Grok, Colossus, and X's distribution under the SpaceXAI umbrella alongside rockets, satellites, and proposed orbital AI infrastructure.

Notable Tweets
“Mechazilla has caught the Super Heavy booster”
The tweet announcing the historic first mechanical booster catch — a feat Musk had set at 50/50 odds.
“SpaceX will put humans on Mars before 2030”
Said during a Twitter Spaces session with reporters.

Predictions
We want to send Dragon to Mars in 2018. And then 2020. And then 2022. And every two years after that, synchronizing with Mars orbital windows.
No Mars missions were launched in 2018 or 2020. Starship development replaced the Dragon Mars plan.
We want to send the first cargo Starships to Mars in 2022 and the first crewed flights in 2024.
Starship had its first integrated test flight in April 2023. Mars cargo missions have not been attempted.
Starship will reach orbit in 2022.
First integrated Starship launch attempt happened April 2023; orbit was not reached until IFT-4 reentry in June 2024.
Famous Quotes
“I think there is a strong humanitarian argument for making life multi-planetary, in order to have a kind of insurance policy against the myriad of possible events that could ultimately extinguish Earth-based consciousness.”
— Reddit AMA, Jun 2016
“I tend to approach things from a physics framework. Physics teaches you to reason from first principles rather than by analogy. So I said, okay, let's look at the first principles. What is a rocket made of? Aerospace-grade aluminum alloys, plus some titanium, copper, and carbon fiber.”
— TED 2013, Feb 2013
“If one can figure out how to effectively reuse rockets just like airplanes, the cost of access to space will be reduced by as much as a factor of a hundred. A fully reusable vehicle has never been done before. That really is the fundamental breakthrough needed to revolutionize access to space.”
— SpaceX press conference, Dec 2015
