In significant space solar power technology development, CalTech‘s Space Solar Power Demonstrator (SSPD-1) has successfully completed its first year-long space mission. The project has made strides in the pursuit of viable space solar power, demonstrating the potential to transmit power wirelessly in space, among other breakthroughs.

Even with unexpected challenges during deployment, the mission successfully tested and validated these technologies. The wrap-up of SSPD-1 signifies a crucial milestone for a project that has been in progress for over ten years and has garnered global interest. “This critical mission demonstrated that [space solar power] should be an achievable future,” commented Caltech President Thomas F. Rosenbaum.

The mission consisted of three main experiments, DOLCE, ALBA, and MAPLE, each focusing on a different technology. DOLCE exhibited the unique architecture of a scalable modular spacecraft; ALBA assessed 32 different types of photovoltaic (PV) cells for robustness in harsh space conditions, while MAPLE proved the feasibility of wireless power transmission at a distance in space.

With the mission now wrapped up, engineers are leveraging the collected data and experiences to propel the future of space solar power. The testbed’s triumphs and lessons are anticipated to influence future space solar power array designs significantly.
