We break down why cooling won’t be what limits space data centers, using first-principles scaling and Starlink V3 as a reference point. This week we had, an Amazon’s Atlas V launch, Starlink’s DTC push in Africa, SpaceX IPO momentum, and growing space-traffic risks as megaconstellations scale.

In light of the holidays, we will not publish next week and will resume with our regular update the following week.

Debunking the Cooling Constraint in Space Data Centers
Orbital Data Centers

Radiative cooling is often cited as a fundamental barrier to space data centers. Using first-principles scaling and Starlink-class hardware, we show that cooling is a manageable engineering trade-off rather than a hard physics constraint.

ULA Atlas V Deploys 27 Amazon Leo Satellites To Expand Broadband Constellation
Amazon LEO

United Launch Alliance (ULA) successfully launched 27 Amazon Leo satellites into low Earth orbit on Dec 16, 2025 using an Atlas V rocket from Cape Canaveral Space Force Station as part of Amazon’s Leo broadband constellation build‑out. This marks the fourth Atlas V mission under the Amazon Leo programme, contributing to the deployment of an internet megaconstellation planned to exceed 3,000 spacecraft aimed at global coverage. The launch went smoothly and aligns with Amazon’s timeline to expand constellation capacity ahead of service scale‑up phases. Atlas V continues to be a reliable vehicle for Leo missions while ULA transitions production emphasis toward Vulcan Centaur

Airtel Africa And Starlink Announce Direct‑To‑Cell Satellite Service Across 14 Countries
DTCStarlink

Airtel Africa confirmed that it has partnered with SpaceX’s Starlink to roll out direct‑to‑cell satellite connectivity across all 14 of its African markets beginning in 2026, enabling basic text messaging and data services via Starlink satellites for compatible smartphones. The collaboration includes support for Starlink’s next‑generation Direct to Cell system that is expected to deliver significantly improved data speeds versus earlier versions. This initiative follows the earlier deployment of Starlink direct‑to‑cell tech by Kyivstar in Europe and aims to extend mobile connectivity where terrestrial networks are minimal or absent. Regulatory approvals and spectrum clearances will still be required in individual countries before full service roll‑out.

This partnership represents Starlink’s strategic expansion into mobile operator integration, potentially unlocking new revenue streams that go beyond traditional broadband subscriptions. By embedding satellite connectivity directly within terrestrial telecom offerings, SpaceX could tap into Airtel’s ~150 million customer base.

STMicroelectronics Confirms 5 Billion Starlink Chip Shipments With Potential Doubling
Starlink

STMicroelectronics announced that it has shipped over 5 billion radio‑frequency antenna chips to SpaceX for its Starlink satellite internet network since around 2015, with the volume of shipments expected to potentially double by 2027 according to senior company executives. These BiCMOS‑based chips are used in Starlink user terminals and form a critical part of the hardware supporting connectivity. The announcement also notes STMicro’s intent to supply future technologies including inter‑satellite laser link components and collaborations on broader constellations in Europe. This reflects deeper semiconductor supply chain integration between terrestrial chipmakers and commercial space operators.

Rocket Lab Shares Drop After JAXA Launch Success
LaunchRocket Lab

Rocket Lab stock fell nearly 10 percent on Dec 15, 2025 despite the company successfully executing its first mission for the Japan Aerospace Exploration Agency (JAXA) from New Zealand, setting a new annual launch record. The share price reaction was attributed by market analysts to “buy the rumor, sell the news” dynamics amid an already strong 2025 performance, with shares up substantially year‑to‑date versus broader markets. There were no operational anomalies reported; the investor response appears to reflect valuation expectations that had priced in success ahead of the event.

SpaceX Completes 550th Falcon 9 Booster Landing With Starlink Deployment
LaunchSpaceX

SpaceX successfully launched 27 Starlink satellites on Dec 14, 2025 aboard a Falcon 9 rocket from Vandenberg Space Force Base. This mission marked the 550th successful landing of a Falcon 9 first stage booster, with booster B1093 completing its ninth flight and landing on the autonomous droneship Of Course I Still Love You. The Starlink megaconstellation now includes over 9,300 active satellites out of more than 10,000 launched since 2019, supporting global broadband access and airline wifi connectivity. This was SpaceX’s 162nd Falcon 9 mission of 2025 and further cements its operational cadence.

Spacecraft From Chinese Launch Nearly Collides With Starlink Satellite, SpaceX Says

Spacecraft From Chinese Launch Nearly Collides With Starlink Satellite, SpaceX Says
ChinaSpace Situational AwarenessStarlink

SpaceX reported that on Dec 9, 2025, one of its Starlink satellites narrowly avoided a collision with a spacecraft launched by China’s Kinetica 1 rocket from the Jiuquan Satellite Launch Center. The close pass occurred within approximately 200 meters at ~560 km altitude and, according to SpaceX’s Starlink VP Michael Nicolls, took place without prior coordination between operators. The Chinese operator CAS Space states it followed standard space awareness protocols and is investigating. The launch also included payloads for the UAE, Egypt, and Nepal, but the specific object involved in the close approach was not publicly identified.

This near‑miss highlights the escalating challenges of space traffic management in low Earth orbit as megaconstellations scale and international launch activity grows. Lack of shared trajectory data and deconfliction protocols can raise insurance and operational risks, potentially increasing costs for operators and regulators alike. This dynamic could accelerate regulatory and commercial demand for enhanced space situational awareness services and formalized multinational coordination frameworks

SpaceX IPO Rumours Intensify On Global Media And Executive Signals
SpaceX

Confirmed reporting from Reuters and Bloomberg indicates SpaceX is actively planning an initial public offering in 2026, with discussions underway with investment banks to raise more than $25 billion and potentially over $30 billion, positioning the valuation over $1 trillion and perhaps as high as $1.5 trillion according to some Bloomberg sources. Elon Musk has publicly signalled on social channels that reports of a 2026 IPO are accurate, validating speculation in the mainstream press. No SEC registration has yet been filed, and timing remains contingent on market conditions, with a mid‑year window widely discussed. These developments follow recent secondary‑market pricing chatter, although Musk previously disputed specific tender valuations.

A Wall Street Journal‑sourced Reuters report confirms Blue Origin has spent over a year developing technology for orbital artificial intelligence data centres, driven by the high energy costs of terrestrial facilities and the potential of constant solar power in space. The initiative is reportedly part of a broader aerospace strategy that includes leveraging satellite assets for compute as well as communications. Simultaneously, SpaceX is said to be upgrading Starlink satellites to carry computing payloads, although specifics are not independently verified. Neither company has officially detailed timelines or commercial plans.
