Solar energy is becoming increasingly present in our daily lives, and startup Reflect Orbital understands this well. The company plans to deploy mirrors in space to redirect sunlight to Earth without interruption.

Space is a vast and largely unexplored place due to numerous physical factors. However, a startup wants to revolutionize its field by sending a giant mirror into our solar system to redirect solar energy back to Earth.

The California-based company Reflect Orbital is behind this amazing project. And with good reason, because although solar energy is now captured in many places around the world in a variety of ways using solar panels, these panels cannot absorb sunlight at night.

For this project, the start-up plans to send a satellite with a large mirror installed on it into space to capture this energy continuously, without interruption. The mirror is made of mylar, which is made from polyester and has a very fine but ultra-resistant surface.

But that's not all, because while sending a satellite into space is now commonplace, another step must be taken, and it's the most important one. The mirror will have to reflect sunlight toward various specific points on Earth in order to deliver a large amount of energy. Needless to say, this requires remarkable technological prowess, as demonstrated by this AI-controlled satellite used in a NASA mission.

Thus, for this stage, two services are already in place, namely energy and lighting. In other words, the first involves sending light emitted by the sun to solar power stations during the night, so that solar panels can produce energy when the sun is not shining. The second involves directing this light to areas of the Earth that need specific lighting, reminiscent of the village of Viganella in Italy, which is lit by a mirror located on a hill.

It should be noted that the start-up has big plans for the long term. It wants to send 57 mirrors to an altitude of 600 km to create an artificial constellation of satellite reflectors in low orbit. If successful, this could prove very useful in many areas of activity.
