Japanese scientists have successfully deployed a miniaturized, spherical rover named SORA-Q on the moon, marking a milestone in autonomous lunar exploration. The rover, measuring only 3 inches (8 centimeters) in diameter, demonstrated autonomous navigation capabilities and wireless data communication during the Japanese Aerospace Exploration Agency's (JAXA) SLIM (Smart Lander for Investigating moon) mission. Launched in December 2023, the SLIM lander achieved Japan's first soft-landing on the lunar surface on January 19, 2024.

Upon landing, the mission deployed both the tennis ball-sized SORA-Q, designated as Lunar Excursion Vehicle-2 (LEV-2), and a secondary hopping robot, LEV-1. SORA-Q was co-developed by JAXA, Sony, Doshisha University, and the toy company Takara-TOMY. Utilizing expertise from the Transformers brand, engineers enabled the rover to transform from its initial sphere shape into a two-wheeled mobile configuration. Once deployed, the device extended its hemispherical segments to function as wheels, while a camera flipped into position and a tail stabilizer allowed it to traverse the lunar surface.

The rover captured color imagery of the SLIM lander and its surrounding environment, including a crater site near the 885-foot-wide (270-meter-wide) Shioli crater. Led by JAXA’s Daichi Hirano, the development team aimed to create a lightweight, autonomous platform capable of accessing tight spaces like crevasses that larger rovers could not navigate. Because of its miniature size, SORA-Q relied on tandem operation with LEV-1 to relay information back to Earth.

Autonomy was achieved by using onboard camera imagery to identify and maneuver around obstacles without direct intervention from mission control. Despite the successful demonstration, the mission experienced a premature end after approximately 100 minutes of operation, falling 20 to 30 minutes short of its projected lifespan. According to Daichi Hirano, the communication link failed likely due to damage sustained by LEV-1 or battery depletion within the hopping unit, both of which were essential for relaying SORA-Q's findings. The mission results are detailed in the journal Science Robotics.
