The Korea Pathfinder Lunar Orbiter (KPLO), officially named Danuri, is the Korea Aerospace Research Institute's (KARI) first exploratory space mission outside of Earth's orbit.
Danuri launched on Aug. 4, 2022, atop a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station, Florida at 7:08 p.m. EDT (2308 GMT).
The spacecraft arrived in lunar orbit in mid-December 2022, after more than a four-month journey. It will orbit our rocky companion for about a year, taking measurements of the lunar surface and identifying potential landing sites for future missions, according to NASA (opens in new tab). Data collected from Danuri will also help support the planning of NASA's Artemis program.

Danuri is a joint mission between KARI and NASA with KARI managing the manufacturing and operation of the orbiter while NASA supports the mission with the development of one of the scientific payloads as well as aiding spacecraft communications and navigation, according to an agreement signed in 2016.
"The KPLO Participating Scientist Program is an example of how international collaborations can leverage the talents of two space agencies, to achieve greater science and exploration success than individual missions," Sang-Ryool Lee, the KPLO Project Manager, said in a NASA statement (opens in new tab).
"It's fantastic that the Korea Aerospace Research Institute (KARI) lunar mission has NASA as a partner in space exploration — we're excited to see the new knowledge and opportunities that will arise from the KPLO mission as well as from future joint KARI–NASA activities," Lee added.
The name Danuri is a combination of two Korean words "dal" which means moon and "nuri" which means enjoy, according to NASA Spaceflight (opens in new tab).
Main goals of Danuri
According to the NASA statement, the three main goals of the mission are:
- Realizing the first space exploration mission by the Republic of Korea (ROK).
- Developing and verifying space technologies suitable for deep-space exploration on future missions.
- Investigating the physical characteristics of the lunar surface to aid future robotic landing missions on the moon.
Danuri's scientific instruments(opens in new tab)
The KPLO will carry six payloads: Five developed by Korean universities and research organizations and one from NASA. They are a Lunar Terrain Imager (LUTI), a Wide-Angle Polarimetric Camera (PolCam), a Magnetometer (KMAG) a Gamma-Ray Spectrometer (KGRS), the Disruption Tolerant Network Experiment Payload (DTNPL) and a highly sensitive camera developed by NASA called ShadowCam (opens in new tab).
NASA's ShadowCam will be used to map reflectance within permanently shadowed regions at the lunar poles to help shed light on the possible presence of frost or ice deposits on the moon's surface. ShadowCam is 800 times more sensitive than the Lunar Reconnaissance Orbiter Narrow Angle Camera on which it's based.
