Subsea Cables & Internet Infrastructure

Blue Origin is a Jeff Bezos' startup providing space services to NASA and other clients. Those services include cargo delivery, rocket engines, lunar landing vehicles, and under development, a commercial space station. Blue Origin's New Glenn rocket carries as much cargo as SpaceX' Starship and successfully launched a NASA probe in late 2025. The first stage is reusable.  New Glenn's success has encouraged Blue Origin to develop new satellite constellations. The company announced yesterday a hybrid network of 5,280 LEO and 128 MEO satellites called Terawave that will use dual free space lasers and radio frequencies to communicate with the Earth. Radio frequency will provide a minimum committed bit rate of 144 Gibabits per second, many magnitudes greater than what Starlink offers, with free space lasers boosting the throughput by 6 terabits in ideal weather conditions. Dual connectivity is not a new idea. Low latency financial trading platforms have been using microwave ...

Satellite competes with terrestrial broadband because they are both access technologies. But all satellite networks generate traffic for the terrestrial backbones including the subsea cables. After all, there is little content stored in space! 😃 Hence satellite Internet providers must access data centers just like every other technology in the telecom world. Inter-satellite free space laser communication will bypass the terrestrial backbones to an extent, but this is really just a drop in the bucket. It works mostly for low bandwidth applications like email and instant messaging.  The graph shows the number of objects launched into low earth orbit from 1960 onward. This includes manned space craft, satellites, and unmanned spacecraft. Note that the dominant factor is SpaceX putting Starlink LEO satellites into orbit. As of January 2025, Starlink has 6,932 in space. In addition, Amazon Kuiper is deploying 3,236 LEO birds with the bulk of the fleet flying into orbit in 2025 and 2026...
