An American startup named Sun Catcher is trying to send energy from one satellite to another using a laser, which could be a major breakthrough in creating space data centers. These projects are gaining interest because of the growing need for electricity, water, and space on Earth. Companies like SpaceX, Blue Origin, and Starcloud are involved in space-related innovations, and Google is set to launch its first AI satellite on October 1st. Another mission, launched on a Falcon 9 rocket, is working to build an electrical network in space. This mission is being carried out by a startup based in Florida that was founded in 2024. The startup is developing a prototype called Protostar, which works in two stages. It collects sunlight, focuses it with lenses, converts it into a laser, and then sends that laser to the solar panels of another satellite to supply power. The first test of this system will involve launching a small satellite called a CubeSat and powering it from a distance as both travel at nearly 27,000 kilometers per hour. Teams on the ground will measure the amount of power received as the CubeSat moves away and compare it to their predictions. If the test is successful, it will be the first time energy has been sent by laser between two independent satellites. In 2023, a U.S. Navy laboratory operated a laser in orbit, but it was a single device with a size of less than 1.5 meters and only 11% efficiency. Sun Catcher’s design is inspired by power systems on Earth, and the startup has signed ten contracts to sell energy, including one with Starcloud. These contracts allow clients to pay a deposit to secure a fixed price for a set period. The U.S. military is watching this development closely and has chosen another company, Katalyst, to demonstrate similar technology. This kind of innovation is important for future space data centers, where each satellite must generate and store its own power, which can limit what they can do. Some of the challenges include making the system efficient, ensuring precise targeting, managing heat, and making it work in the vacuum of space. If successful, this technology could support more advanced and powerful operations in space, opening the door for more complex missions and infrastructure beyond Earth.
