Korea Pathfinder Lunar Orbiter (KPLO)

NSSDCA ID: KPLO
COSPAR ID: 

Description

The Korea Pathfinder Lunar Orbiter (KPLO) is South Korea's first lunar mission. It is developed and managed by the Korea Aerospace Research Institute (KARI) and is scheduled to launch in July 2022 to orbit the Moon for 1 year carrying an array of South Korean experiments and one U.S. built instrument. The objectives are to develop indigenous lunar exploration technologies, demonstrate a "space internet", and conduct scientific investigations of the lunar environment, topography, and resources, as well as identify potential landing sites for future missions.

Spacecraft and Subsystems

The spacecraft has a cubic shape with two solar panel wings and a parabolic antenna mounted on a boom. The total mass is 550 kg. Communications are via S-band (telemetry and command) and X-band (payload data downlink). Power (760 W at 28 V) is provided through the solar panel arrays and rechargeable batteries. A monopropulsion system is used, with four 30N orbital maneuver thrusters and four 5N attitude control thrusters. KPLO is equipped with five science instruments and a Disruption Tolerant Network experiment. The five experiments are a Lunar Terrain Imager (LUTI), a Wide-Angle Polarimetric Camera (PolCam), a Magnetometer (KMAG), a Gamma-Ray Spectrometer (KGRS), and a high-sensitivity camera developed by NASA (ShadowCam).

Mission Profile

KPLO is scheduled to launch in July 2022 from Cape Canaveral on a SpaceX Falcon 9 into a 300 km Earth orbit, followed by a translunar injection burn and a one month lunar transfer phase. After capture into an elliptical lunar orbit, it will circularize to a 100 km nominal polar orbit (+-30 km), from which it will conduct science operations for one year. If the mission has an extended phase, it will descend to a 70 km orbit or lower.
