Phi-Sat-2 (also known as ɸ-Sat-2) is an Earth observation CubeSat mission from the European Space Agency (ESA) capable of running AI apps directly on board. What makes Phi-Sat-2 particularly noteworthy is its utilization of the NanoSat MO Framework, a modular and open-source platform designed for small satellite missions.

The NanoSat MO Framework enhances the satellite's flexibility and adaptability, allowing for efficient integration of AI technologies into its operational workflow through Apps that can be installed on board. The AI Apps will be able to do different activities such as transforming a satellite image to a street map, detecting clouds, detect and classify maritime vessels, and to perform image compression using AI.{{cite book|chapter-url=https://www.spiedigitallibrary.org/conference-proceedings-of-spie/11858/1185814/Overview-of-ESA-Earth-observation-CubeSats-missions/10.1117/12.2597557.short|publisher=SPIE|doi=10.1117/12.2597557 |access-date=5 December 2021|title=Sensors, Systems, and Next-Generation Satellites XXV |year=2021 |last1=Pastena |first1=Massimiliano |last2=Melega |first2=Nicola |chapter=Overview of Esa Earth Observation Cubesats Missions |page=30 |isbn=9781510645608 |s2cid=239079888 |editor-first1=Steven P. |editor-first2=Toshiyoshi |editor-first3=Sachidananda R. |editor-first4=Arnaud |editor-last1=Neeck |editor-last2=Kimura |editor-last3=Babu |editor-last4=Hélière }}
