Astrobee

Description

Astrobee is a cube-shaped, free-flying robotic system developed to assist astronauts and ground controllers within the interior of the International Space Station. It succeeded the Synchronised Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) programme, replacing the older CO2-powered units with a more versatile, fan-propelled design. The system consists of three distinct robots named Bumble, Honey, and Queen, which navigate the station autonomously using vision-based mapping to perform routine tasks without human intervention. Primary users include NASA and commercial researchers who utilise the robots as a modular platform for testing new sensors, software, and hardware in microgravity. The units are designed to carry out environmental monitoring, such as checking sound levels and air quality, and documenting inventory via radio-frequency identification (RFID) scanning. Research payloads are integrated via physical expansion ports, allowing third-party developers to run experiments on the platform without the expense of building a dedicated satellite. Potential risks include the degradation of internal propulsion fans and the complexity of maintaining reliable wireless communication within the metal-dense environment of the station modules. The desk would seek to verify the current duty cycle of the active units and the status of the integrated docking station, which handles automated recharging and data transfer. Verification of the specific software update frequency for the Guest Science programme would also be necessary to assess current research capacity.
