Our satellites also saw the Eclipse! 🌒 These images were taken by FOSSA satellites' ADCS during different phases of this week's solar eclipse. A unique perspective, straight from the eyes of our constellation.

Our first public image from a FOSSA Spacecraft! Definitely looks round.
Our newest satellite is up and running in orbit, and its ADCS is already tracking the Sun and the Earth’s horizon precisely. 🛰️ During early in-orbit testing, our Fine Sun Sensor captured the Mediterranean sea, Italy and the Balearic Islands rolling by beneath our solar panels.

Not in-range here yet, but FossaSat-2E26 from the Transporter-17 deployment very much alive as received by numerous EU tinyGS stations hours ago!

Only hours after deployment from Transporter-16, the latest @FossaSys FossaSat-2E25 coming in loud & clear! Passing over the Central U.S., 125k LoRa decodes via tinyGS + my Arduino-R4_WiFi running much of the original FossaSat-1 code
