With ‘Thousand Sails,’ China joins the race to fill up Low Earth Orbit with mega-satellite constellations.
It’s getting crowded up there in Low Earth orbit (LEO). By now, flocks of Starlinks have become a familiar sight, and the bane of astrophotographers as the ‘vermin of the skies.’ Now, several new competitors have joined the fray, with more waiting in the wings.

On December 2nd, 2021, the commercial space company Rocket Lab unveiled the detailed architecture of their Neutron rocket for the first time. In a live-streamed event, the company showcased all the new elements that will make this “megaconstellation” launcher a serious contender in the coming years. These include updated details about the rocket’s design, materials, propulsion, and reusability architecture.

In the near future, humanity stands a good chance of expanding its presence beyond Earth. This includes establishing infrastructure in Low Earth Orbit (LEO), on the surface of (and in orbit around) the Moon, and on Mars. This presents numerous challenges, as living in space and on other celestial bodies entails all kinds of potential risks and health hazards – not the least of which are radiation and long-term exposure to low gravity.
These issues demand innovative solutions; and over the years, several have been proposed! A good example is Dr. Pekka Janhunen‘s concept for a megasatellite settlement in orbit around the dwarf planet Ceres, the largest object in the Main Asteroid Belt. This settlement would provide artificial gravity for its residents while the local resources would allow for a closed-loop ecosystem to created inside – effectively bringing “terraforming” to a space settlement.
