It will provide critical information about the terrain and water in such regions to help plan future crewed and robotic missions there. While the Moon has lost its global magnetic field, it does have localized magnetic features such as “swirls.” By measuring their weak magnetic fields from orbit, Danuri will help us understand the extent of protection they offer from harmful space radiation, and the nature of the Moon’s leftover magnetic areas as hints of its past.ĭanuri’s final instrument, ShadowCam, is an ultrasensitive camera provided by NASA to see inside permanently shadowed areas on the Moon. The last of Danuri’s indigenous instruments is a magnetometer. Together with the polarimetric camera, Danuri will better help understand the Moon’s mineral composition, and how its terrain has evolved over four billion years. The energy levels of these rays are linked to the elements that produce them, allowing scientists to determine the elemental makeup of specific Moon materials. This will help us better understand the Moon’s surface composition and the nature of its varied volcanic deposits.ĭanuri also has a gamma-ray spectrometer, which will look at highly energetic gamma rays released from the Moon. The other is a wide-angle polarimetric camera which can determine the type of surface materials based on the way light reflects and scatters off them. After entering a roughly 100-kilometer circular lunar orbit, Danuri will study the Moon for at least a year with its five scientific instruments starting in January 2023.ĭanuri sports two indigenously built cameras, one of which will image the Moon’s surface at a high resolution of 2.5 meters per pixel. Danuri was launched on a ballistic lunar trajectory, which allowed it to reach the Moon in December 2022.
