Company mission
SpaceX's mission is to make humanity multiplanetary. The company is working on a next generation of fully reusable launch vehicles that will be the most powerful ever built, capable of carrying humans to Mars and other destinations in the solar system.
  • Benefits and Perks - Our employees’ well-being is important to us and essential to our capacity to do extraordinary things. We offer a wide variety of programs to support the health, wellness, and financial security of our employees and their families.
Company Values
  • Make History - SpaceX has gained worldwide attention for a series of historic milestones. It is the only private company capable of returning a spacecraft from low-Earth orbit, and in 2012 our Dragon spacecraft became the first commercial spacecraft to deliver cargo to and from the International Space Station. And in 2020, SpaceX became the first private company to take humans there as well.
  • Reusability - SpaceX believes a fully and rapidly reusable rocket is the pivotal breakthrough needed to substantially reduce the cost of space access. The majority of the launch cost comes from building the rocket, which historically has flown only once.
  • Landing - SpaceX’s family of Falcon launch vehicles are the first and only orbital class rockets capable of reflight. Depending on the performance required for the mission, Falcon lands on one of our autonomous spaceport droneships out on the ocean or one of our landing zones near our launch pads.
