[9] On 23 May 2022, the South Korean Ministry of Science and ICT officially named the Korea Pathfinder Lunar Orbiter (시험용 달 궤도선, 試驗用月軌道船) as "Danuri" (다누리).

Hydroxyl and water molecules are thought to be transported throughout the lunar surface by mysterious unknown mechanisms, and they seem to accumulate at permanently shadowed areas that offer protection from heat and solar radiation.

[20] To test the experimental system of the “space Internet”, Danuri successfully forwarded a number of photos taken, as well as several video files, including, BTS’ “Dynamite” from outer space to Earth at Korea's Ministry of Science and ICT, Korea Aerospace Research Institute (KARI), and the Electronics and Telecommunications Research Institute (ETRI) on 7 November 2022.

[7] Five instruments are from South Korea and one from NASA:[23][14][20] ShadowCam is a hypersensitive optical camera designed to collect images of permanently shadowed regions (PSRs) near the Moon's poles.

This allows ShadowCam to map the reflectance of these regions to search for evidence of ice deposits, observe seasonal changes, and measure the terrain inside the craters.

[26] The instrument is based on the Lunar Reconnaissance Orbiter LROC narrow angle camera (NAC), but it is 200 times more sensitive[27] to allow for capturing details within the permanently shadowed regions.
