Huffman Coding
Huffman coding is a lossless data compression algorithm that assigns variable-length codes to different symbols based on their frequency of occurrence. The more frequent a symbol is, the shorter its code will be. This algorithm is widely used in space and astronautical engineering for compressing data that is transmitted between spacecraft and ground stations, as well as for storing data on board spacecraft. Huffman coding is particularly useful in space missions where bandwidth and storage capacity are limited, as it allows for efficient use of these resources. The algorithm was invented by David A. Huffman in 1952 while he was a graduate student at MIT.
