Google and NASA are developing a robotic assistant intended to support astronauts during future deep-space missions. The system would combine basic health-monitoring capabilities with practical tasks such as retrieving equipment, managing supplies and assisting with maintenance.
The project involves Google Cloud, NASA’s Human Research Program, the Johnson Space Center robotics team and the Jet Propulsion Laboratory. It builds on the Crew Medical Officer Digital Assistant, an AI-based medical support system that the two organizations have been evaluating since 2025.
The need for onboard assistance could become more significant during missions far from Earth. According to Jim Kelly, Google’s public sector vice president, a mission to Mars could face round-trip communication delays of up to 44 minutes, making immediate consultation with Earth-based medical teams difficult during an emergency.
The robot is not intended to replace a crew medical officer or make independent diagnoses. Instead, it would perform physical tasks under human supervision. For example, an astronaut suffering severe back pain possibly linked to kidney stones could ask the robot to retrieve and prepare an ultrasound system. A medical officer would then examine the images and decide on the appropriate response.
The machine is also being designed as a general-purpose payload handler. When not supporting medical activities, it could organize tools, secure compartments, move cargo and assist with routine maintenance, helping a small crew use its time more efficiently.
Early testing has focused on basic robotic abilities. Google is adapting navigation technology developed at NASA’s Jet Propulsion Laboratory, while DeepMind’s MuJoCo physics simulator has been used to evaluate movement and object handling. During initial laboratory trials, the robot located and moved a medical bag successfully in 85% of attempts.
That result reflects a limited retrieval task and does not demonstrate that the system can reliably perform examinations or support complex emergencies. Google describes the project as a proof of concept, and there is no confirmed fully integrated, space-ready robot.
The proposed system is ultimately intended to respond to simple voice commands while remaining under astronauts’ direct supervision. Possible uses include capturing basic vital signs and assisting with simple ultrasounds under the guidance of a human crew medical officer. NASA has not provided detailed information about the project, saying it is examining several advanced AI initiatives with partners for potential future missions.
