LUNAR-A was a cancelled Japanese spacecraft project that was originally scheduled to be launched in 1995, then delayed to August 2004. After many delays (primarily due to potential thruster faults), the project was eventually cancelled in January 2007. It was planned to be launched on a Japanese M-V rocket from the Kagoshima Space Center.

==History== The vehicle would have been cylindrical, with a diameter of 2.2 m and a height of 1.7 m. It would have had four solar panels and was engineered to be spin-stabilized. Plans called for it to enter an elliptical orbit around the Moon, and deploy two penetrators at an altitude of 40 km on opposite sides of the lunar body. The penetrators were to have been braked by a small rocket at an altitude of 25 km, then free fall to the surface. They were designed to withstand a collision speed of 330 meters per second to deeply penetrate the lunar regolith.
