In a groundbreaking initiative, a Montréal-based startup is set to introduce a network of satellites designed to supply energy to lunar craft. Volta Space Technologies recently announced its ambitious plan to harness solar energy from space and beam it to spacecraft on the moon through advanced laser technology. This innovation aims to support lunar missions, particularly during the two-week-long night cycle or in permanently shadowed regions.
The concept originated from a project within the International Space University, evolving into a venture that garnered attention in NASA’s Watts on the Moon contest. The proposed system, known as LightGrid, will consist of satellites orbiting the moon, capturing solar power and transmitting it to landers and rovers via lasers. This capability will ensure continuous operations for lunar vehicles, even when direct sunlight is unavailable.
Volta has already attracted considerable interest from potential clients, with projected contracts exceeding $250 million. Their technology, which has been successfully tested over distances of 850 meters on Earth, is preparing for a satellite mission in Earth’s orbit in 2026.
The startup envisions deploying a fleet of at least three small satellites to create a reliable energy supply. According to the team, these satellites can be easily scaled to accommodate additional customers, offering global coverage right from the onset.
Volta is eyeing future applications for their power transmission technology beyond the moon, exploring solutions for emergency services, national security, and energy supply on Earth. The potential for cross-industry benefits emphasizes the broad significance of their innovative approach to power distribution.
Innovative Lunar Satellite Network Aims to Power Moon Missions
