What is the difference between .vicar and .pjpg?

Description: The VICAR (Video Image Communication And Retrieval) Image file format is a flexible, image-processing and data format system used primarily by the planetary science community. Developed by NASA's Jet Propulsion Laboratory (JPL) for storing and managing digital images from space missions, VICAR files are designed to support a wide range of image types, including scientific and engineering data from various spacecraft instruments. This format is characterized by its ability to handle multi-dimensional arrays of data.; A PJPEG file is a bitmap image created in the Progressive JPEG format (PJPEG). It contains encoded bitmap data so that the downloaded image appears progressively from a blurry picture to the final sharp image. PJPEG files may also fill alternating horizontal lines until the full picture is revealed.
