Orbital data centers have become one of the most talked-about topics in space.
Making them a reality comes down to several technical challenges, including power, one of the industry’s longest-standing bottlenecks. (1/3)

Solestial is a cost-effective alternative to III-V solar that doesn’t compromise performance.
For large-scale space infrastructure to move from concept to deployment, success will depend on power that can be produced faster, launched sooner, and scaled efficiently. (3/3)

In just a few years, we've advanced our radiation-annealing Si solar tech from flexible coupons to 1-meter modules, and even to a 5.5-meter long deployable blanket.
Each step reflects our team’s rapid iteration, disciplined engineering, and commitment to redefining space solar.
