But there is a vast difference between launching satellites and operating an industrial-scale computing infrastructure in orbit. Space is unforgiving. Radiation damages electronics. The electronics generate enormous amounts of heat, and getting rid of that heat is surprisingly difficult in space. Repairs are extraordinarily expensive, and every pound launched into orbit still carries a significant cost.
First off, consider what goes into an Earth-based data center, like those that you’ve probably begun to see pop up everywhere. These facilities power cloud computing, video streaming, online banking, scientific computing, and increasingly, artificial intelligence. But a data center is much more than a room full of servers.
WASHINGTON — Rocket Lab is acquiring satellite telecommunications company Iridium for $8 billion as part of its effort to become an end-to-end space company.
The companies announced an agreement June 29 under which Rocket Lab will acquire Iridium for $54 a share in cash and stock, valuing Iridium at $8 billion. That is a 24% premium over the closing price of Iridium’s shares June 26. The deal is projected to close in mid-2027 pending regulatory and other approvals.
Mesh Optical came out of stealth in February when it announced that it raised a $50 million Series A led by Thrive Capital.
Before founding Mesh Optical, the startup’s co-founders, Travis Brashears, Cameron Ramos, and Serena Grown-Haeberli, developed the optical communication links that keep thousands of SpaceX’s Starlink satellites interconnected.
The Mesh co-founders saw an opportunity to develop optical transceivers for terrestrial data centers, as light-based hardware is faster and more energy-efficient than traditional electrical-based systems.
TAMPA, Fla. — British startup Shield Space plans to combine its autonomous satellite operations software with ClearSpace’s in-orbit servicing capabilities to address emerging orbital threats.
The startup signed a memorandum of understanding June 23 with ClearSpace’s British subsidiary to develop sovereign space defense capabilities for the United Kingdom and its allies, which they say are increasingly important as adversaries step up efforts to monitor, disrupt and potentially disable critical satellite infrastructure.
Founded in 2025, Shield Space is developing software designed to keep satellites operating autonomously even when communications with the ground are disrupted.

SpaceX may have just dropped its biggest hint yet about what comes after Starship Flight 13. Indeed, FINALLY! Starship’s Next Giant Leap may be here as the new filings point toward an Orbital Return Demo that could mark the next major milestone on the road to full reusability. With that work continues at Starbase on Pads 1 and 2, the Gigabay, and future launch infrastructure. Elsewhere this week, we cover Falcon 9 launches carrying BlueBird satellites, Starlink, and another classified NRO mission, Cargo Dragon’s return from the International Space Station, Astrobotic’s Griffin lunar lander preparing for launch, Ariane 6’s impressive upgraded debut with its heaviest payload yet, and the dramatic demolition of historic structures at Space Launch Complex 6.
A new race to the moon is emerging between the United States and China. Unlike fifty years ago, the goal is no longer just about landing and leaving, but establishing a base that allows for a sustainable presence and extended stays on the surface of our natural satellite. The objective is now to use the moon as a testing ground for technologies that will enable us to travel further, particularly to Mars.
One of these key technologies is in-situ resource utilization (ISRU), which involves using available resources on-site to produce the consumables necessary for human activities: oxygen, water, rocket fuels, or construction materials. By producing these essentials directly on the moon, it will be possible to significantly reduce the mass of cargo sent from Earth, thereby reducing the logistical and financial costs of space exploration. Instead of importing these resources from Earth, the goal is to learn how to live on the moon.
Breaking down lunar dust to extract oxygen At the dawn of humanity’s sustainable return to the moon, ISRU is emerging as a strategic pivot. One of the major challenges is producing oxygen from regolith, the layer of soil covering the moon, primarily composed of small rock fragments and dust. The composition of regolith is complex, mainly consisting of several minerals (plagioclase, pyroxene, olivine) themselves made up of a mixture of metal oxides—chemical compounds that combine oxygen with another element such as silicon, iron, or calcium.
Since 2019, GPS signals across Europe, Greenland and Canada have experienced a huge spike in sudden, widespread signal blackouts. These have resulted in disruptions and degraded performance in navigation systems that airplanes and ships rely on to travel safely.
Some causes are known, such as military jamming on the ground, but others have been a total mystery. A new paper published on the arXiv preprint server points an accusatory finger at Russia, claiming that a constellation of Russian satellites is likely responsible for many of these interference events, which have been blasting out waves of radio static from space.
The study focuses on how these events affected the Global Navigation Satellite System (GNSS) that GPS relies on. The researchers studied 75 separate days on which at least one major interference event occurred.
