As the pace of space launches increases and missions beyond Earth become more abundant and varied, it is important to look for new ways to obtain energy so that these ships can travel to their destinations. Fuel is not infinite, so there comes a point where it runs out. Therefore, there are three main proposals. One is to resupply the ships directly in orbit. Another option is to resort to nuclear energy. In fact, There are already several agencies working on it.
Finally, there is the option of solar energy. Unfortunately, this has some limitations, but the American company Star Catcher wants to solve them through the world’s first energy network located in space.
A good economic injection. Star Catcher just announced which has received 65 million dollars in a series A financing round. With what they already had in their coffers, the company has 88 million dollars. Enough to date its first release to the end of this year.
Different ways to “squeeze” the Sun. The solar energy we are used to is obtained through plates with photovoltaic cells installed directly on the Earth. However, there are already companies that want to bring it directly from the Sun, even at night. Its goal is to use mirrors that reflect sunlight at will anywhere on Earth, whatever the time and whether the weather is good or not. The problem is that these companies They are being criticized a lot for posing risks such as great light pollution.
On the other hand, what Star Catcher wants to do is slightly different. They will also take solar energy directly into space, but they will not direct it to Earth, but to the spacecraft that need it. It will be like a kind of space solar power plant.
Optical beaming. Star Catcher will be based on a phenomenon known as optical beaming. This consists of extracting solar energy and using it to power a multispectral optical laser, with which it will be redirected to satellites from which it can be distributed at will to the ships that need it. To do this, they hope to be able to put a constellation of 200 satellites into low Earth orbit.
Previous records. Last year, this company broke the world record for wireless electricity transmission by delivering 1.1 kW of power to NASA’s Kennedy Space Center. Now, they want to transmit directly to space.
It also has limitations. Although this company does not have the same limitations as those that want to redirect sunlight to Earth, it involves placing an immense number of satellites in orbit, with the risk that this entails.
Many experts warn that, in the same way that could happen with Elon Musk’s Starlink constellation, this type of infrastructure increases the risk of Kessler syndrome. That is, it could happen that one or more fragments of space debris collide with them, deteriorating and launching pieces into space that would become more space debris, which in turn would collide with more satellites or more debris. Thus, a very dangerous domino effect would be generated for satellites, ships and space stations that are in space at that time.
Even more risks. On the other hand, the launches of the ships that will place the satellites into orbit are also a great source of pollution. In fact, recently has been published a study that warns of the large amount of polluting substances that these types of launches leave in the upper layers of the atmosphere, where, otherwise, the pollution would be residual. In short, this company will bring us great advances, but it will have to maneuver carefully so as not to bring even more problems.
