China Plans Moon-Orbiting Telescope Array by 2026.

China plans to launch a constellation of satellites around the moon to create a radio telescope that would allow astronomers to study cosmic radiation in the electromagnetic spectrum below 30 MHz, which is impossible to study from Earth's surface. The proposed "Discovering Sky at the Longest Wavelength" project could orbit the moon as early as 2026 and would consist of one "mother" satellite and eight mini "daughter" craft. The moon's far side is the most radio-quiet place in the solar system and would provide an ideal environment for this kind of measurement.
