Astrobee robot cube assists astronauts on International Space Station

A small robotic cube known as Astrobee is actively assisting astronauts aboard the International Space Station. NASA developed these free-flying robotic assistants to support mission operations in microgravity. The program began in 2019 with the arrival of the first two units, named Bumble and Honey. A third robot, named Queen, joined the station later that same year. Seven years after the initial deployment, the Astrobee program remains operational and effective.

The robots are designed to help astronauts test new technologies and allow mission teams on Earth to better observe the interior of the station. They also assist with everyday tasks for the crew. In a recent image taken by NASA astronaut and Crew-13 commander Jessica Watkins, an Astrobee robot is shown operating within the station’s Kibo laboratory. The metal cubes are approximately the size of a toaster and move autonomously through the spacecraft.

The compact design and autonomous flight capabilities of Astrobee distinguish it from previous robotic systems in space. While not the first robot to operate on the space station, its form factor gives it a unique presence that resembles a companion to the crew. The continued success of the program raises questions about the future evolution of robotic assistants in space, including potential applications for lunar missions where robots might autonomously explore and aid astronauts.
