The astronaut assistant known as CIMON 2 just launched for the orbiting lab aboard SpaceX's robotic Dragon cargo capsule, which lifted off today (Dec. 5) from Cape Canaveral Air Force Station in Florida.
CIMON 2 is following in the footsteps of the original CIMON (Crew Interactive Mobile Companion), which reached the ISS in the summer of 2018, also aboard a Dragon.
Both robots were developed by the European aerospace company Airbus on behalf of the German space agency, DLR, and employ IBM's Watson system as their AI.
