A satellite watcher has captured new images of China’s mysterious space plane during its third flight.

Launched on December 14, 2023, by a Long March 2F rocket, the robotic vehicle was photographed by Felix Schöfbänker in Upper Austria.

The images reveal two features at the end of the plane, which Schöfbänker speculates could be solar panels or antennas, not depicted in available computer renderings.

He estimates the craft to be about 30 feet (10 meters) long, potentially longer than the American X-37B space plane, though the exact size could be affected by the angle of illumination.

The vehicle, which recently lowered its orbit to approximately 217 miles (350 kilometers) above Earth, is oriented with its nose facing forward, Space.com has reported.

The purpose of this mission remains unknown, akin to the secretive operations of the U.S. Space Force’s X-37B, which launched on December 29, 2023, and is now 216 days into its mission.
