Sierra Space is building a shared ecosystem in space for scientific collaboration and innovation to benefit life on Earth.

With technologies that make space more affordable and accessible, we're dedicated to creating a prosperous and secure space economy that will benefit all of humanity.

Rapidly advancing toward the launch of the next generation of space transportation, the world's first commercial spaceplane, Dream Chaser(r), will perform cargo supply and return missions for NASA - delivering up to 12,000 pounds of cargo to the International Space Station (ISS) at a time.

Sierra Space is also the developer of the Large Integrated Flexible Environment (LIFE(tm)), a modular, three-story inflatable habitat that we are developing as we build the first commercial space station. The unique structure will provide opportunities for multiple businesses including manufacturing, pharmaceuticals, and other sectors, to optimize zero gravity benefits.
