Starlink Satellite Versions Explained: v0.9 to V2 Mini

Not all Starlink satellites are the same. Since the first batch launched in 2019, SpaceX has steadily redesigned the spacecraft — making them heavier, more capable, and able to talk to each other with lasers. Understanding the generations helps explain why newer satellites are brighter, why some carry more capacity, and what the constellation will look like as it grows.

v0.9 — the prototypes (May 2019)

The very first 60 Starlink satellites were a test batch, often labelled v0.9. They proved the basic design — flat-panel body, a single solar array, krypton-fuelled ion thrusters — but lacked features that came later. Most have since been deorbited. They were never meant to be permanent operational satellites.

v1.0 — the first operational fleet (2019–2021)

Version 1.0 was the first design deployed at scale, with thousands launched through 2020 and into 2021. Each weighs around 260 kg and uses the now-familiar flat-pack design that lets up to 60 stack inside a single Falcon 9 fairing. v1.0 satellites do not have inter-satellite laser links, so they rely entirely on ground stations to route traffic.

v1.5 — adding laser links (late 2021–2022)

Version 1.5 introduced optical inter-satellite links — lasers that let satellites pass data directly to their neighbours in orbit instead of always bouncing it off a ground station. This was a big step: it enabled coverage over oceans and remote regions far from any gateway, and reduced latency for long routes. v1.5 became the backbone of the constellation through 2022.

V2 Mini — bigger and more capable (2023 onward)

The full Version 2 satellites are large enough to need SpaceX's Starship to launch. As an interim step, SpaceX built the V2 Mini — a heavier (~800 kg) satellite that still fits on Falcon 9. V2 Minis carry more powerful phased-array antennas and provide several times the capacity of a v1.5, which is how Starlink keeps adding bandwidth as its subscriber base grows. A V2 Mini variant also carries Direct to Cell payloads that connect ordinary mobile phones.

How to tell which version you're seeing

There is no version field in the public orbital data, but the launch date is a strong clue: satellites launched in 2019–2020 are v1.0, those from late 2021–2022 are typically v1.5, and 2023 onward are V2 Mini.
