What are Starmind Satellites?

 Proposed by SpaceX in 2026, Starmind is a planned mega-constellation of orbital artificial intelligence data centers. While SpaceX's Starlink network is designed to move and relay data, Starmind is specifically designed to execute massive AI computing and model inference directly in space.


The project aims to transition spacecraft from isolated sensing nodes into an interconnected "orbital intelligence fabric," allowing heavy data processing to happen in orbit before the finalized, smaller results are beamed back to Earth.

The Engineering & Economics (Why Space?)

The Starmind architecture is designed to bypass the three major bottlenecks currently limiting terrestrial AI data centers: land availability, electrical grid constraints, and cooling requirements.

  • Continuous Solar Power: By operating in a Sun-synchronous orbit, Starmind satellites can capture solar energy continuously, completely avoiding atmospheric diffusion, weather interruptions, and the day/night cycle. Elon Musk has characterized this approach as building a "sentient sun".

  • Vacuum Radiator Cooling: Terrestrial AI data centers require immense amounts of energy and water for chillers, cooling towers, and fans. In the vacuum of space, heat from the processors can be radiated directly outward, reducing the cooling power overhead by an order of magnitude.

The AI1 Satellite Hardware

  • Massive Scale: The first-generation Starmind satellite design, designated AI1, is large enough that it relies entirely on the heavy payload capacity of the Starship rocket for deployment. When fully deployed, it stands up to 30 meters tall with a solar array wingspan of 75 meters—wider than the fuselage of a Boeing 747.

  • Compute Payload: Through a co-engineering partnership with Nvidia, each AI1 satellite effectively houses a rack-scale AI system. The payload is slated to carry 36 Nvidia Vera CPUs, 72 Nvidia Rubin GPUs, and an NVLink interconnect system, delivering a peak compute payload of up to 250 kW (175 kW average) per vehicle.

Network Architecture

  • Laser Interconnects: The satellites will not operate in isolation; they will use high-bandwidth optical inter-satellite links (lasers) to network their computing power together in orbit.

  • Earth Backhaul: To deliver the finished AI computations back to users on the ground, Starmind will route its data through the existing Starlink constellation, utilizing it as a low-latency backhaul.

Deployment Schedule and Scope

  • Constellation Size: In January 2026, SpaceX filed an application with the FCC for a Starmind constellation ceiling of up to 1,000,000 satellites.

  • Manufacturing: To meet this scale, SpaceX is constructing a dedicated "Gigasat Factory" in Bastrop, Texas, and recently ordered 100 gigawatts' worth of advanced solar cell manufacturing equipment.

  • Timeline: The first two AI1 prototypes are scheduled to launch on Starship test flights in early 2027. Volume production and mass deployment are targeted to begin by late 2027 or 2028.

What is SSDV? No, it is not a typo!

Image
This week, every amateur radio satellite enthusiast is busy decoding and posting SSTV (Slow Scan TV) images from International Space Station. Now what is SSDV? SSDV is the abbreviation for Slow Scan Digital TV, in contrast to SSTV which is analog and has been there for a long time. It has been mentioned that SSDV is a packetised digital form of SSTV. I heard of SSDV first when I read about the recently launched ASRTU-1 amateur radio satellite, which has a UHF SSDV in addition to the V/U transponder and 10GHz high resolution image downlink onboard. UBSEDS24 Balloon with SSDV launched from Bristol, UK sometime back had recorded nice SSDV images of the clouds from above. Lunar-OSCAR-94 which went into lunar orbit had transmitted SSDV images back to radio amateurs on Earth. WSJT JT4G was used for messages and transmissions were on 435.400 and 436.400 MHz. Transmitting power was about 2W, using VHF/UHF SDR transceivers. It was the world's smallest spacecraft to enter lunar orbit indep...

What is a double conversion superheterodyne receiver?

Image
 We have seen that usual superheterodyne radio receivers have single conversion of received frequency to the intermediate frequency using a single local oscillator and mixer. In many of the modern communications receivers, multiple successive stages of frequency conversions with multiple intermediate frequencies are used. A receiver with two frequency conversions and two intermediate frequencies is known as a double or dual conversion superheterodyne receiver. One with three levels of conversion and three intermediate frequencies is known as a triple conversion superheterodyne receiver. Use of additional conversions improve adjacent channel selectivity and image frequency rejection. First IF stage has a wide separation between the intended signal and the image frequency, enabling RF amplifier to reject the image frequency. Second IF filter has a narrow bandwidth providing good adjacent channel selectivity. Single IF stage in conventional superheterodyne receivers is a tradeoff betw...

Have you heard of zBITX?

Image
 Well, I had not heard till I read the program schedule of LARC-7 today. Most of you would be familiar with uBITX which has gone up to version 6. Some of you would be aware of sBITX, which is quite an advance over uBITX. Almost daily I am meeting a new uBITX user on the band, most of them using additional linear amplifiers. That made me join the BITX group on groups.io , where I am getting messages from uBITX and sBITX users from all sides of the globe. Still I was not aware of zBITX and that made me look around and came across two references. One was the video of a talk by VU2ESE at QRP ARCI . Another was an email in the BITX groups.io which was citing the former. zBITX is a new transceiver from VU2ESE based on Raspberry Pi Zero for 20W, having CW skimmer and FT8 modes in addition to the regular SSB mode and waterfall display which the sBITX also has. zBITX is quite small, just 3" x 3" x 1.5" in size. It is a Raspberry Pi Zero based 20 W software defined radio which h...
