Final answer:
MDIS stands for Mercury Dual Imaging System, an instrument suite on the MESSENGER spacecraft used for mapping Mercury's surface geology.
Step-by-step explanation:
MDIS stands for Mercury Dual Imaging System, an instrument suite on the MESSENGER spacecraft used for mapping Mercury's surface geology. The MDIS is an instrument on NASA's MESSENGER spacecraft, which was used to capture high-resolution images of Mercury. The acronym MDIS stands for Mercury Dual Imaging System. It is a scientific instrument suite on the MESSENGER spacecraft, which was a NASA mission to Mercury. MDIS includes two cameras: a wide-angle and a narrow-angle camera. The purpose of this system was to map the geology and morphology of Mercury's surface. By doing so, MDIS has helped scientists understand Mercury's geological history and the composition of its surface materials.
