About Sierra Space

Sierra Space products and programs are working towards a more accessible space
economy. The company is rapidly advancing toward the launch of the world’s only
winged commercial spaceplane, the Dream Chaser®. As the next generation of space
transportation, the Dream Chaser will perform cargo supply and return missions for
NASA, set to begin in late 2022, delivering up to 12,000 pounds of cargo to the
International Space Station (ISS) at a time. The return journey will carry critical data,
generated by ISS researcher experiments, enabling earth-bound scientists to benefit
from much faster access to these unique results. Dream Chaser is a reusable
spaceplane, uniquely capable of a smooth 1.5 low-g re-entry for crew and cargo
transportation with the ability to land on existing commercial runways worldwide.

Sierra Space is the developer of the Large Integrated Flexible Environment (LIFETM)
Habitat, a modular, three-story commercial habitation and science platform. The unique
structure will provide opportunities for multiple businesses including manufacturing,
pharmaceuticals, and other sectors, to optimize zero gravity benefits. The LIFE Habitat
will be able to be deployed in low-Earth orbit, on the lunar surface, or lunar orbit, and as
a transport vehicle to Mars. Both Dream Chaser and LIFE Habitat will launch using
conventional rocket propulsion systems.

The Dream Chaser spaceplane and LIFE platform are central components of the joint
partnership Orbital Reef commercial space station and mixed-use business park being
developed in partnership with Blue Origin.
