via the ARRL: Lunar-Orbiting Microsats with Ham Radio Payloads Will Make Use of WSJT JT4G Sub-Mode

China’s twin-launch Chang’e 4 mission to the far side of the moon will place a pair of microsatellites in lunar orbit “to test low-frequency radio astronomy and space-based interferometry.” The two satellites, DSLWP-A1 and DSLWP-A2 (DSLWP = Discovering the Sky at Longest Wavelengths Pathfinder) are expected to launch in June. They will carry Amateur Radio and educational payloads, but not a transponder.

Equipped with low-frequency antennas and receivers, the astronomy objectives of the two spacecraft will be to observe the sky at the lower end of the electromagnetic spectrum — 1 MHz to 30 MHz — with the aim of learning about energetic phenomena from celestial sources. They will use the moon to shield them from radio emissions from Earth.
