The standard way to keep track of objects in orbit involves watching sunlight bounce off them, which works great right up until a satellite slides into Earth’s shadow. Then, for a stretch of every orbit, the lights go out, and if you were a satellite hoping to quietly change course without anyone noticing, that is exactly when you would do it. [Stephen Clark reports at Ars Technica](https://arstechnica.com/space/2026/11/anduril-demos-night-vision-sensor-for-tracking-satellites-in-darkness/) that Anduril’s first satellite, Anduril-216, carries a sensor built to close that window. The sensor is a long-wave infrared camera, which means it does not need reflected sunlight at all; it detects the heat spacecraft give off, including during eclipse. Thurn described the capability as a “unique capability for us to witness when an adversary or other resident space objects are maneuvering during those eclipse periods, where in the past we’ve been fairly blind.” The translation from defense-contractor-ese is roughly: we built night-vision goggles for orbit, aimed at everyone else’s satellites. ![A satellite projects a red beam toward a smaller glowing satellite orbiting above Earth against a dark, textured space background.](https://rews.cc/img/03f2ac9c2ecdb5ccbb4764d9e4a3fd1c5d09f954.webp) The fun detail is where the technology came from. To build the infrared space sensor, Anduril’s engineers adapted imaging technology the company already uses in its autonomous weapons. This is either an efficient reuse of existing engineering or a sentence that will appear, quoted, in someone’s think piece about the militarization of space, depending on your priors. Both, presumably. The company released a single image from the sensor on Tuesday — an infrared view of the Moon hanging above Earth’s horizon — as a sort of appetizer. Thurn said it offers just a taste of the instrument’s abilities, and noted that “the long-wave infrared capability we have on orbit can do both unresolved and resolved imagery.” Resolved imagery, close enough in, means inspecting other satellites rather than merely dotting them on a chart. For now the focus is low-Earth orbit, though Thurn said the sensor could work in other orbits and eventually in cislunar space near the Moon. Worth noting who actually built the satellite: not Anduril. The spacecraft platform for Anduril-216 came from Apex Space, a satellite-manufacturing startup, and Subramanian said Anduril has no plans to stand up its own satellite production line. The plan instead is to buy third-party satellite buses and bolt on Anduril’s own sensor and compute modules for whatever mission is at hand. The compute module on this one fuses data from different sensor types — infrared, visible imagers — and works out tracking solutions on board, without waiting for humans on the ground to help. ![Gloved hands assemble a small solar-powered camera device, inserting a circuit board and attaching a lens, with loose screws nearby.](https://rews.cc/img/efc2d2783d503eec254e5b9c08d474ddcab70e7e.webp) “You’re seeing that today with Anduril-216, where we started with a simple mission, which was how do we track satellites, especially in these eclipse periods where the US currently does not have the ability to maintain custody,” Subramanian said. “And we designed a mission around that.” And then there is the business model, which is the part I find most telling. If you were a defense contractor who had just built a clever satellite sensor, the traditional move would be to sell the government the satellite, or at least the sensor, at an enormous and lovingly cost-plussed price. Anduril’s current plan is weirder and arguably smarter: keep the hardware, sell the data. Subramanian said the company’s focus is on acquiring space domain awareness data for sale to the US military — subscription surveillance, essentially — rather than selling satellites or sensors outright. “At present, Anduril is not offering this system as a merchant supplier,” he said, adding: “That could change in the future.” The incentive structure here is neat. If you sell a satellite, you get paid once and your customer owns the capability. If you sell the feed, you get paid forever, you keep the fleet, and every eclipse your competitors can’t see through is, commercially speaking, your product’s whole pitch. Whether the US military prefers owning its orbital night vision to renting it is a separate question. But “fairly blind” is the current baseline, and blindness, as a starting point, leaves a lot of room to sell sight.
