A thriving economy in space is needed to make life on Earth more vibrant, sustainable, and equitable. Space technology will enable global access to information, solutions to climate change, answers to global food security, products that transform healthcare, clean energy production, and more. Today, rocket launch options are slow, expensive, and unreliable. Stoke is building the world’s most efficient fully and rapidly reusable rocket designed to fly daily that will radically increase access to space and open up the space economy to safeguard our precious home, Earth.
